[Technique Optimization of Interposition Arthroplasty During Proximal Row Carpectomy with Regard to the Vascularity of the Capsule in Carpal Joint: Cadaverous Study]. / Optimalizace techniky interpozicní artroplastiky pri proximální karpektomii s ohledem na vaskularizaci dorzální kapsuly karpu: kadaverózní studie.

PURPOSE OF THE STUDY The study aimed to propose an optimal based fl ap creation with the view to ensure long-term survival of the interposition arthroplasty. MATERIAL AND METHODS A total of 28 dorsal wrist capsules were collected from 16 cadavers (with age range at death 18 to 80 years, with no visible wrist pathology). Altogether 112 histological specimens were obtained from these 28 samples. Post-hoc Dunn's tests were used to analyse the percentage of vascularisation of individual sides of the dorsal capsule (circumference and area) at the 0.05 level of signifi cance. Spearmann's correlation analysis was used to assess the effect of age on vascularization of the dorsal wrist capsule. In cadavers in whom both capsules were collected, the limbs were compared. For the sake of comparison, the Wilcoxon matched pairs test was used. RESULTS Regarding statistical signifi cance, the largest share of the total circumference and area of the measured vessels of the dorsal capsule is constituted by the distal side (35.2% of the circumference and 30.9% of the area). The blood supply of the dorsal capsule received on the ulnar side is the lowest (12.9% of the circumference and 17.6% of the area). There was no signifi cant effect of age on vascularization of the dorsal wrist capsule confi rmed. Also, the comparison of vascularization of both limbs from a single cadaver did not yield any statistically signifi cant results. DISCUSSION Proximal row carpectomy is a long-established surgical technique used to manage the degenerative changes in the wrist. Our results showed the best vascularization on the distal and radial sides of the dorsal wrist capsule. In this light, the distally-based fl ap or the fl ap described by Berger, which respects the clinically important ligaments, appear to be the least invasive and help maintain the future stability of the wrist. CONCLUSIONS In clinical practice, we advise that a radially-based fl ap according to Berger is created and the distal side of the dorsal capsule, the most vascularized portion based on our results, is preserved as much as possible. The fl ap created in this manner also preserves the important carpal ligaments and appears to the authors of this study to be the most benefi cial, also with respect to the presence of the largest arteries, contrary to the distal side. Another option is to use a distally-based fl ap for interposition arthroplasty. Key words: interposition arthroplasty, proximal row carpectomy, vascularization, degenerative changes, wrist.

How to proceed with a patent popliteal artery aneurysm below the chronic superficial femoral artery occlusion?

INTRODUCTION: The indications for popliteal artery aneurysm treatment are clear. In aneurysms with patent inflow and outflow arteries, the risk of peripheral embolisation from a mural thrombus is high and the treatment, mostly a vascular intervention, is focused on preventing this extremity-threatening complication. It is unclear, however, how high the risk of peripheral embolisation is and how to proceed with a patent popliteal artery aneurysm fed by the deep femoral artery when the superficial femoral artery is chronically occluded. METHODS: All patients diagnosed with popliteal artery aneurysm between 2015 and 2019 were searched in the database of the Department of Surgery II of University Hospital Olomouc. Patients with a patent popliteal artery aneurysm and chronic superficial femoral artery occlusion in the ipsilateral extremity were selected. RESULTS: We diagnosed 66 patients with 85 popliteal artery aneurysms. Four patients had a patent popliteal artery aneurysm and chronic superficial femoral artery occlusion in the ipsilateral extremity. In these patients, conservative treatment was indicated after the diagnosis was determined. In three patients, no clinically obvious complication of the popliteal artery aneurysm occurred. In one patient, popliteal artery aneurysm thrombosis occurred after a follow-up of 21 months, leading to a shortening of his calf claudication distance and limiting the patient. CONCLUSION: Our experience with this small group of patients shows the possibility of primary conservative treatment in patients with a patent popliteal artery aneurysm below the chronic superficial femoral artery occlusion site. Aneurysm thrombosis can be expected during follow-up. Patients in whom the thrombosis leads to limitations are indicated for surgical intervention. The risk of peripheral embolisation from the mural thrombus cannot be excluded with certainty. Further studies involving large groups of patients are needed to provide a more precise recommendation.

[Reconstruction of Lower Extremity Palsy after Pelvic Fractures with the Muscle Transfers]. / Rekonstrukce paréz dolní koncetiny po zlomeninách pánve svalovými transfery.

PURPOSE OF THE STUDY The prevalence of nerve structure injuries accompanying pelvic and acetabular fractures is stated to be 5-25 %, with most frequent injuries to motor nerve structures associated with fractures of the posterior wall of the acetabulum. Prognostically worse outcomes of regeneration are documented mainly in iatrogenic, intraoperative injuries to nerve structures. This study aims to document the functional effect of muscle transfers restoring the movement of lower extremities with irreversible nerve lesion caused by the pelvic and acetabular fracture. MATERIAL AND METHODS A total of 18 patients with irreversible palsy of lower extremities in L4-S1 segments underwent a reconstruction surgery in the period 2006-2016, of whom 13 patients with the mean age of 42 (21-79) years arrived for a follow-up. The group included 10 patients with the loss of function of peroneal portion of the sciatic nerve, one patient sustained femoral nerve lesion and two patients suffered complete sciatic nerve lesion (both the peroneal and tibial portion). The patients were evaluated at the average follow-up of 77 (24-129) months after the reconstruction surgery. The average time interval from pelvic fracture to reconstruction by muscle transfer was 47 (18-151) months. Due to a wide spectrum of functional damage, the patients were evaluated in terms of the overall effect of the reconstruction surgery on the activities of daily living using the LEFS (The Lower Extremity Functional Scale). The surgical techniques used transposition of tensor fascie latae for femoral nerve lesion, transposition of tibialis posteriormuscle for palsy of the peroneal division of the sciatic nerve and tenodesis of tibialis anterior tendon and peroneus longustendon for the palsy of the peroneal and tibial portion of sciatic nerve. RESULTS The effect of movement restoration on daily living evaluated using the LEFS achieved 65 points (53-79) which is 85% of the average value of LEFS in healthy population. The transposition of active muscles tibialis posterior and tensor fasciae latae resulted in all the patients in active movement restoration. A loss of correction of foot position following the performed tenodesis of the paralysed tibialis anterior muscle was observed in one patient, with no significant impact on function. No infection complication was reported in the group. In 78% of patients the intervention was performed as day surgery. DISCUSSION There is a better prognosis for restoration in incomplete nerve lesion than in complete lesions and also in the loss of sensation than in the loss of motor function. The mini-invasive stabilisation of pelvic ring according to literature does not increase the risk of nerve lesions, while on the other hand a higher incidence of femoral nerve damage by INFIX fixator is documented. The type of muscle transfer is selected based on the availability of active muscles suitable for transposition and also with respect to functional requirements of the patient. CONCLUSIONS Irreversible palsy of lower extremity after the pelvic fracture is easily manageable as to the restoration of function. Surgical interventions using the preserved active muscles to restore the lost movement should be a component part of comprehensive surgical care for patients who sustained a pelvic fracture and should be performed centrally at a centre availing of comprehensive expertise. Key words: nerve lesion, tendon transfer, acetabulum, pelvis, fracture.

[Distal Ulna Malunion as the Result of Distal Ulnar Shaft Fracture Treated by Three-Dimensional Corrective Osteotomy]. / Malpozice distální ulny po zlomenine distální diafýzy resená trírovinnou korekcní osteotomií.

The team of authors presents a case of the patient who suffered an isolated unstable extra-articular distal ulnar fracture, the surgical treatment of which was affected by a postponed management in consequence of inadequate primary treatment. The primary non-operative treatment resulted in a complex malunion ad latus, ad axim and ad peripheriam. The malunion which led to a painful restricted range of motion of the forearm (59%), decreased hand grip strength and significant limitation of activities of daily living was surgically treated by a triplane corrective osteotomy at 11 months after injury. At 12 months after surgery, a complete ulnar bone union was observed, the patient showed no residual wrist pain, the range of motion of the injured forearm reached 97 % of the range of motion of the unaffected forearm (side), and the hand grip strength was 95% of the hand grip strength in contralateral limb. The treatment outcome can be assessed as very good based on the Quick DASH score. Displaced isolated distal ulnar fractures cause a change in the axial position of the distal end of the bone and can be associated with an injury to the stabilizers of the DRUJ. Thus, they can result in a limited range of motion of the forearm due to the impaired DRUJ biomechanics and development of early post-traumatic osteoarthritis of the DRUJ. The non-operative treatment is recommended only for stable and non-displaced fractures as well as fractures in which surgical treatment is contraindicated. Corrective osteotomy of the distal ulna is the method of choice in managing distal ulna malunion as a result of isolated distal ulnar shaft fractures in symptomatic patients. Good functional outcomes may be achieved if the anatomical position of DRUJ is restored. Key words:corrective osteotomy, distal ulnar fracture.

[The Effect of Activation of the Shoulder Girdle Muscles on Functional Outcomes of Rehabilitation in Patients with Surgically Treated Distal Radius Fractures]. / Vliv aktivace pletencového svalstva na funkcní výsledek rehabilitace po frakturách distálního radia osetrených operacne.

PURPOSE OF THE STUDY The aim of the study was to assess the functional outcomes of rehabilitation in patients with surgically treated distal radius fractures in the early postoperative period. We compared the functional outcomes of patients undergoing standard rehabilitation with the group of patients whose postoperative rehabilitation was extended with shoulder girdle exercises of the affected upper limb while the wrist was immobilized. Several indices and variables were used for the assessment of the functional therapeutic outcomes of the affected wrist. MATERIAL AND METHODS Forty patients (32 females and 8 males, the mean age 60.5 years) with distal radius fractures treated by internal fixation using volar surgical approach were involved in the study between 2013-2016. The tested subjects were randomized and split into two groups according to the selected method of rehabilitation. The tested subjects with standard rehabilitation extended with shoulder girdle muscles activation were labelled as group I. It included patients (n = 20) of the mean age 59.8 (age range 42-73 years) with immobilized wrist (i.e. for 3-4 weeks) performing shoulder girdle muscles exercises at the same time. Furthermore, standard kinesiotherapy continued after their fixation was removed. The other tested group, labelled as group II (n = 20), the mean age 61.3 (variation 40-74 years of age) involved patients with distal radius fractures. Only standard rehabilitation was performed in this group as late as their forearm fixation was removed. The following indices and parameters were assessed in the early postoperative period (i.e. by 8 weeks after the fixation removal): wrist and fingers range of motion (ROM), hand grip strength (dynamometry), local swelling, pain, scores of a nine hole peg test (NHPT), and a DASH score. RESULTS After the fixation had been removed, the group I reported statistically significantly higher values of movement compared to the values of the contralateral limb in the following directions: dorsal flexion, palmar flexion, MP joints flexion, flexion of PIP joints (proximal interphalangeal), and flexion of DIP joints (distal interphalangeal). After eight weeks, the group I manifested significantly higher values in dorsal flexion, palmar flexion and ulnar deviation in the wrist. There were no significant differences in other movement directions. The hand grip strength mean value examined with a dynamometer was significantly higher in the group I in the sixth and eighth week of testing (group I - 58.9% strength of a healthy limb after six weeks, or 66.5% after eight weeks). The results in the group II were 49.9% strength of a healthy limb after six weeks, or 56.6% after eight weeks. The group I showed statistically significantly lower values of wrist swelling and higher finger dexterity in the NHPT in all measured weeks. Lower pain intensity in the group I during the measurements was observed. At the same time, this group showed significantly better results in the DASH score. DISCUSSION The results of this study are useful for clinical practice. They confirm a functional relation between the activity of hand muscles and the shoulder muscle activity. The differences in the functional ability of the hand and the functional state of the injured wrist were detected as early as in the early postoperative period. It could be stated that the tested subjects in the group I showed a greater and faster improvement in the physical function of the injured hand. This was also accompanied by a positive psychological effect. We had not found a study of a similar type in the available literature that we could have compared our submitted results to. CONCLUSIONS Shoulder girdle muscles exercises after a distal radius fracture, while wrist is immobilized, can evidently enhance functional capability and accelerate the hand-function restitution. Early functional outcomes of the injured wrist after the rehabilitation with shoulder girdle muscles exercises support the efficiency of this broadened rehabilitation protocol. Key words: distal radius frac,ture, hand, shoulder, functional treatment, rehabilitation.

[Comparison of Short-Therm Results of Conservative versus Operative Treatment of Distal Ulna Fractures Associated with Distal Radius Fracture Treated by Plate Osteosynthesis]. / Srovnání casných výsledku konzervativní a operacní lécby zlomenin distální ulny pridruzených pri zlomenine distálního radia resené dlahovou osteosyntézou.

PURPOSE OF THE STUDY The study aims to evaluate and compare the results of conservative and operative treatment of individual types of distal ulna fractures associated with distal radius fracture treated by plate osteosynthesis and to verify the conclusions of the other authors regarding the recommended therapeutic procedures in these fractures. MATERIAL AND METHODS In the period from 08/2013 to 09/2015, a total of 81 patients participated in the prospective randomised study, with the mean follow-up period of 24 months (6-36). All the fractures of distal two thirds of ulnar styloid process were treated conservatively. The patients with the other types of ulnar fractures (fractures of the proximal third of ulnar styloid process, ulnar head fractures, subcapital fractures) were systematically divided into two cohorts, based on which the subsequent (conservative vs. operative) treatment of distal ulna fractures was indicated. The operative treatment of all the types of distal ulna fractures was performed by plate osteosynthesis using LCP Distal Ulna Plate implant so that a uniform method is applied. RESULTS In the post-operative follow-up not a single patient with tip fracture of ulnar styloid process in the cohort showed a posttraumatic instability or disorder of distal radioulnar joint (DRUJ) biomechanics (ROM 96.6% (91-100), MWS 61.3 points (75-100), QDASH 2.9 points (0-6.8)). The patients with a fracture of the proximal third of ulnar styloid process, a fracture of ulnar head and a subcapital fracture, treated operatively, achieved better early radiographic and functional outcome (ROM 95.7% (60-100), MWS 91.2 points (75-100), QDASH 3.5 points (0-11.4)) than patients treated conservatively (ROM 89.6% (64-100), MWS 70.4 points (35-85), QDASH 18.4 points (0-52.3)). DISCUSSION The study confirms the conclusions drawn by the other authors that tip fractures of ulna do not cause posttraumatic DRUJ instability and do not require operative treatment. Conservative treatment of ulnar base fractures led to non-union in 60% of cases and to malunion in 25% of cases, altogether in 15 patients (75%) the clinical examination revealed a conclusive posttraumatic DRUJ instability of various severity and these patients showed healing in malunion ad latus greater than 2 mm and non-union of the fracture. By performing anatomical reduction and osteosynthesis of ulnar "base fractures", the stability and DRUJ function were restored in all the patients, thus also a better functional outcome was attained. Conservative treatment of ulnar head fractures brought worse outcomes due to malunion of fractures resulting in a noncongruent articular surface of DRUJ or a change in axial position of the distal end of the bone. The change in DRUJ biomechanics resulted in a limited rotation of radius and a limited range of forearm mobility. The operative treatment of subcapital ulna fracture had a very good early outcome as compared to conservative treatment of the fracture which healed in malunion, the change of axial position of the distal end of the bone resulted in a limited range of forearm mobility. CONCLUSIONS Based on the early functional and radiographic outcomes of RCT study it can be stated, in agreement with the other authors, that the operative treatment of distal ulna fractures associated with the distal radius fracture treated by ORIF should be indicated for base fractures of ulnar styloid process associated with DRUJ instability following the osteosynthesis of distal radius fracture and peripheral fragment dislocation ad axim or ad latus in radial direction by 2 mm and more, and also in case of displaced ulnar head fractures and instable and displaced subcapital fractures of the ulna. Key words: distal ulna fracture, plate osteosynthesis, LCP distal ulna plate.

[Plate Osteosynthesis of Distal Ulna Fractures with Associated Distal Radius Fractures Treated by Open Reduction and Internal Fixation. Short-Term Functional and Radiographic Results]. / Dlahová osteosyntéza zlomenin distální ulny pri soucasné zlomenine distálního radia resené dlahovou osteosyntézou - casné funkcní a rentgenové výsledky.

PURPOSE OF THE STUDY: The aim of the study was to describe the indication criteria and operative technique and to present the first conclusions of a prospective study dealing with an assessment of functional and radiographic findings in patients with concurrent fractures of the distal ulna and distal radius; the former was treated by osteosynthesis using an LCP Distal Ulna Plate (De Puy Synthes, USA) and the latter by plate osteosynthesis. MATERIAL AND METHODS: Between August 2013 and September 2014, 18 patients (3 men and 15 women; average age, 58 years; range, 25-74 years) with a fracture of the distal ulna and a concurrent distal radius fracture were treated by plate osteosynthesis. The indications for surgery included displaced ulnar styloid base fractures in 10 patients, displaced comminuted fractures of the ulnar head in seven patients and a subcapital fracture of the ulna in one patient. The average follow-up was 9 months, with 13 (72%) patients being followed up for 6 months at least. The outcome of surgery was evaluated on the basis of X-ray views and multiplanar reconstruction of CT scans. Functional results were based on measuring the range of motion at wrist and forearm and hand grip strength and on the scores obtained from the Mayo Wrist Score System and Quick DASH Questionnaire. RESULTS: The average values for wrist and forearm range of motion were as follows: 68° in flexion (60-80°), 71° in extension (40- 90°), 87° in pronation (70-90°), 81° in supination (50-90°). This corresponded to a 92% (74-100%) range of motion at the contralateral wrist and forearm. The average hand grip strength measured with a dynamometer was 80.6% (53-100%) of the gripping force exerted by the unaffected extremity. Post-operative X-ray and CT findings showed good reduction of both distal radius and distal ulna fractures as well as good fragment retention by means of LCP implants. During follow-up complete bone union and full stability of the radioulnar joint were achieved in all patients. The functional outcome of treatment was shown by the average Mayo wrist score and Quick DASH score of 84 (55-100) and 7.4 (0-47.7) points, respectively. DISCUSSION: The functional outcome of treatment in our patients corresponded to the severity of their distal forearm fractures. The patients with more serious distal radius fractures, frequently associated with ulnar head fractures, had poorer functional results than the patients with less serious fractures. According to the AO classification, in the distal radius fractures, prevailing fracture types were 23-C3 (78%) and 23-C2 (16%). In relation to the distal ulna fracture type, the patients with ulnar styloid base fractures had better functional results than the patients with ulnar head fractures, because a fracture of the styloid process does not affect the congruency of the distal radioulnar joint (DRUJ). Fractures of the ulnar styloid process base, following distal radius fracture osteosynthesis, were invariably associated with DRUJ instability. This fracture type is always accompanied by injury to the distal radioulnar ligament of the triangular fibrocartilage complex (TFCC) and, in case of a displaced fracture, surgical management is indicated. In agreement with the results of other authors it was found in our study that, when the anatomical position of the distal radioulnar joint had been achieved, both the functional and the radiographic findings were post-operatively very good. The final average values for the range of wrist and forearm motion, hand grip strength and hand and arm function were assessed as very good. CONCLUSIONS The assessment of our results and their comparison with the literature data showed that osteosynthesis of distal ulna fractures with concurrent distal radius fractures managed by open reduction and internal fixation are indicated in displaced fractures of the ulnar styloid process base, displaced comminuted fractures of the ulnar head where fragments interfere with DRUJ congruency, and unstable displaced subcapital fractures of the ulna. The early results of this study provide evidence for the efficiency of plate osteosynthesis in the treatment of distal ulna fractures.

[Scaphoid excision and four-corner fusion using the variable angle locking intercarpal fusion plate for treatment of post-traumatic degenerative changes of the wrist]. / Excize clunkové kosti a ctyrrohá fúze zápestí pomocí VA-LIF v lécbe degenerativních poúrazových zmen zápestního kloubu.

PURPOSE OF THE STUDY: The aim of this study is to compare functional and X-ray results before and after four-corner arthrodesis using an angular stable dorsal circular plate in patients with post-traumatic degenerative changes of the wrist. METHODS: Nine consecutive patients with scapholunate advanced collapse (SLAC) or scaphoid nonunion advanced collapse (SNAC) of the wrist, stage III, underwent scaphoid excision and four-corner fusion using angular stable plate fixation. The wrists were immobilised using a split for two weeks and then a removable wrist brace with assisted physiotherapy for four weeks. Minimal followup was 18 months. Clinical assessment before and after surgery included the wrist range of motion (ROM), grip strength, presence of pain, disabilities of the arm, shoulder and hand (DASH) scores, and radiographic findings of the carpal height and ulnar translation ratios. Differences were statistically tested. In addition, patients' satisfaction with functional outcomes was evaluated. RESULTS: In the post-operative period the patients experienced less pain during daily activities and had a better carpal height ratio than before surgery; these differences were statistically significant. In the other criteria, although showing better post-operative results, improvement was not statistically significant. Eight patients were satisfied with the final outcome. One patient required limited denervation of the wrist for pain relief. There was no non-union. DISCUSSION The functional outcomes (ROM, grip strength) in our patients at follow-up were fully comparable with the previously published studies. Although, by most postoperative treatment protocols, physical therapy is started at four to eight weeks of rigid fixation of the wrist, no non-union was found in our group of patients who had a shorter period of post-operative fixation. CONCLUSIONS: Four-corner arthrodesis of the wrist using angular stable dorsal circular plate fixation provides pain relief with acceptable preservation of the range of motion and no consolidation problems. Long-term follow-up and a larger group of patients would be necessary to confirm these hopeful results.

[Anatomy notes on minimally invasive plate osteosynthesis of the proximal humerus. A cadaver study]. / Anatomické poznámky k miniinvazivní dlahové osteosyntéze proximálního humeru - kadaverózní studie.

PURPOSE OF THE STUDY: The aim of the study was to assess the average length of a proximal and a distal incision, to verify the location of the axillary nerve and to identify risk factors for nerve injury during minimally invasive plate osteosynthesis. MATERIAL AND METHODS: During cadaver study a total of 24 implantations using the Philos angular stable plate were performed from the minimally invasive anterolateral approach. A five-hole plate inserted with the aid of new Philos aiming device was used in all cases. The plate was fixed with four screws proximally and with three screws to the diaphysis. After implantation either of the incisions were joined and the axillary nerve was exposed on the lateral side of the arm. RESULTS: The nerve was not found to be injured during plate implantation in any of the cases. The average length of the proximal incision was 56 ± 2.8 mm (52-64 mm) and that of the distal incision was 32 ± 2.5 mm (28-35 mm). The middle free part covering the axillary nerve was on average 45 ± 4.3 mm (38-54) long. The average width of the nerve was 1.9 ± 0.35 mm (1.4-2.8 mm). The average distance of the axillary nerve was 39 ± 2.9 mm (37-44 mm) from the superior facet of the greater tubercle and 53 ± 3.9 mm (48-60) from the lower edge of the acromial process. In 80% of the cases the nerve was located in the area determined for the screws going to the medial calcar region; in 20% it was over a hole for the screw directed towards the centre of humeral head. Nerve location above the first six most proximally placed screws was not recorded in any of the cases. DISCUSSION: The minimally invasive anterolateral approach is an alternative technique for osteosynthesis of proximal humerus fractures using angular stable plates. Advantages reported by a number of authors include lower incidence of avascular necrosis of the humeral head, an easier way of reduction and a better view of the rotator cuff. On the other hand, this approach is associated with a higher risk of damage to the axillary nerve. Distance of axillary nerve from acromion is very variable. It may be located in the range of 30 to 85 mm from the acromial edge. CONCLUSION: The anterolateral approach is, when respecting the anatomical position of the axillary nerve, a safe alternative to the conventional deltoideopectoral approach.

[Are malleolar fractures easy to treat?]. / Jsou operace malleolárních zlomenin snadné?

Malleolar fractures rank among the most frequent skeletal injuries. The majority of orthopaedic and trauma surgeons incline to surgical therapy with anatomical reposition and retention going for absolute stability. Recommended surgical techniques with screws, plates or tension-band wiring usually presents no problems for surgeons. Unsatisfactory postoperative radiological results, however, are often tolerated because revision surgery may not always have expected results. Difficulties in decision-making for right treatment are (a) the classification and right interpretation of the fracture type, (b) the question of stability and right treatment of syndesmotic injury, (c) the reconstruction of the distal fibula in length and without malrotation, (d) the question of surgical stabilization of the posterior tibial edge, and (e) the diagnostic and therapeutic approach to the medial osteoligamenteous complex. It is necessary to realise that, whatever classification has been used, injury proceeds in connected stages and can stop in each stage (Lauge-Hansen). Both supination and pronation osteoligamenteous injuries have specific patterns. It is important to analyse these patterns and put right therapeutic consequences. Included in this analysis must be the question of the right management of syndesmotic injury. It needs attention for exact reposition and retention of the distal fibula. Also, a fracture analysis of the medial complex is very important for right osteosynthesis following the principles in fracture treatment. In fractures of the anterior colliculus of the medial malleolus, the deep part of deltoid ligament can also be injured. The listed problems with their critical analyses and interpretations show that injuries of the ankle joint can be difficult to diagnose and treat. In conclusion references to these problems are critically interpreted.

[Early suture versus ligamentoplasty of scapholunate ligament injury: comparison of clinical results]. / Casná sutura versus ligamentoplastika léze skafolunátního vazu - srovnání klinických výsledku

PURPOSE OF THE STUDY: The aim was to evaluate subjective and objective criteria of wrist, hand and arm function in a group of patients with acute static scapholunate dissociation treated by acute suture or ligament reinsertion, and in a group of patients with chronic static scapholunate dissociation treated by ligament reconstruction using ligamentoplasty. MATERIAL AND METHODS: Of a total number of 70 patients treated surgically for scapholunate instability at the Department of Trauma Surgery, University Hospital in Olomouc and the Department of Trauma Surgery, University Hospital in Brno, from 2002 till the end of 2008, 37 patients with acute or chronic static scapholunate dissociation treated by suture, ligament reinsertion or ligamentoplasty were selected. Of them, 17 patients with chronic scapholunate dissociation and 10 patients with acute scapholunate dissociation appeared at the final follow-up. The assessment of subjective criteria was based on the Disabilities of the Arm, Shoulder and Hand Score, the Wrightington Wrist Function Score and the Visual Analogue Scale. The objective criteria included range of motion and grip strength, and radiographic parameters, such as scapholunate gap and scapholunate and scaphocapitate angles. Satisfaction of the patients and their return to work were also evaluated. The results were statistically analysed using the Chi-square, Mann-Whitney-U and Wilcoxon tests, with the level of significance a=0.05. RESULTS: In the group with acute static scapholunate dissociation, the objective criteria showed an improved range of flexion- extension. The range of radial and ulnar bending and grip strength were almost identical with those of the healthy wrist. In both evaluated groups the self-rated criteria had almost the same values in all three rating systems used. No statistically significant difference in any of the values compared was recorded. DISCUSSION: The results of subjective and objective assessments were comparable in the two groups. Paradoxically, some items of the subjective evaluation were better in the patients undergoing ligament reconstruction - ligamentoplasty. This can probably be explained by different subjective comparison of pre- and post-operative conditions in each group. Even though the subjective assessment was almost identical in both groups, we definitely find an advantage in acute treatment of a scapholunate ligament tear by suture. A technically easier procedure, a shorter period of restricted hand and arm function for the patient, no degenerative changes due to instability and a lower risk of complications - they all give support to this technique. Later conversion to another type of stabilisation if ligamentoplasty fails may bring problems and give much worse results than a failure of acute sutures CONCLUSIONS: An acute operative treatment of scapholunate ligament injury is regarded as a more suitable method for scapholunate dissociation. Ligamentoplasty, because of technical demands and risk of post-operative complications, can be used as a method of choice if the acute sutures of a torn scapholunate ligament fail or scapholunate dissociation is diagnosed at a late stage.

[A Palmar percutaneous volar versus a dorsal limited approach for the treatment of non- and minimally-displaced scaphoid waist fractures: an assessment of functional outcomes and complications]. / Palmární perkutánní nebo dorzální limitovaný operacní prístup v lécbe minimálne dislokovaných a nedislokovaných zlomenin strední tretiny clunkové kosti: funkcní výsledky a rozbor komplikací.

PURPOSE OF THE STUDY: Non-displaced or minimally displaced scaphoid waist fractures can be surgically treated using either the percutaneous volar or the limited dorsal approach.These techniques provide a possibility of early wrist physiotherapy throughout the healing period, better functional outcomes and a shorter sick leave duration.Many reports cite low complication rates.The purpose of this study is to compare both techniques based on the complication rate and functional outcomes. MATERIAL AND METHODS: The authors compared 42 patients treated for an acute scaphoid waist fracture by percutaneous osteosynthesis and 38 patients treated by osteosynthesis using a limited dorsal approach after a follow-up of at least 12 months. The differences between the groups were tested statistically. RESULTS: The overall complication rate was 11.9% for the percutaneous approach and 15.8% for the dorsal approach. There was one case of non-union in each group. The differences in the complication rates as well as in the range of wrist motion and in persistent complaints were statistically insignificant. We found significantly (p=0.042) better grip strength for the percutaneous approach. DISCUSSION: Most of the complications detected were due to a technical error during surgery and can be minimized by meticulous adherence to the technique. The difference in grip strength is very close to the significance level set for the study, and this will be necessary to clarify in a planned prospective study. CONCLUSIONS: Based on the statistical analysis of the results of our clinical data, the two techniques are comparable.

[Hybrid procedures in the treatment of type IV and V thoracoabdominal aneurysms]. / Hybridní výkony v lébe torakoabdominálních výdutí typu IV, V.

OBJECTIVE: To evaluate our experience with hybrid endovascular and open surgical treatment of thoracoabdominal aneurysms. MATERIAL AND METHODS: Between 1996 and 2008 8 patients with thoracoabdominal aneurysm (6 Crawford type IV and 2 type V) from the total of 257 aortic aneurysms with elective endovascular repair were treated using hybrid procedure. A retrograde revascularisation of visceral and renal arteries through the open access and endovascular exclusion of aneurysms using a stent-graft were done. RESULTS: A primar technical success of the hybrid procedure was in all cases. There was no severe ischaemia of visceral organs, kidneys (no need of haemodialysis) or spinal cord (paraplegia). One patient died on an acute pancreatitis 14 postperative day. Further follow up (in range 16-52 months) showed henceforth a successful exclusion of all the aneurysms without evidence of endoleak and patency of all bypasses with a good function of revascularised organs. CONCLUSION: Owing to minimal haemodynamic load and technical simplicity with a short time of organ ischaemia hybrid procedure represents an acceptable possibility of type IV and V thoracoabdominal aneurysms repair.

[Proximal row carpectomy in the treatment of degenerative arthritis of the wrist]. / Proximální karpektomie v lécbe poúrazových degenerativních zmen zápestního kloubu.

PURPOSE OF THE STUDY: To evaluate the outcome in patients treated by proximal row carpectomy at a follow-up of at least 12 months. MATERIAL: A total of 28 patients were treated by proximal row carpectomy for degenerative arthritis of the wrist due to previous trauma to the wrist or avascular necrosis of the lunate. Of them, 24 underwent a follow-up examination at least 12 months post-operatively. Proximal row carpectomy was indicated in 11 patients for scaphoid non-union advance collapse (SNACwrist), in five patients for scapholunate advanced collapse (SLAC-wrist), in four patients for inveterate dislocation of the wrist, and in four patients for avascular necrosis of the lunate. Ten patients with proximal row carpectomy were simultaneously treated by partial resection of the posterior interosseous nerve and two patients by limited radial styloidectomy. In one patient we performed distraction resection arthroplasty of the wrist using the Fitzgerald method. METHODS: The follow-up clinical and radiological examinations were performed after a minimum of 12 months post-operatively.We evaluated the range of wrist motion, grip strength, the presence of resting pain and pain dusing physical activities and the patient's satisfaction with the treatment outcome. By radiological examination we assessed radiocapitate joint degeneration and translation of the capitate bone in relation to the lunate facet of the radius. The differences between the results of pre- and post-operative clinical examinations were statistically evaluated using the Student's t-test, Sign test, Mann-Whitney test, and Wilcoxon signed rank test. The results were considered to be significant if p < 0.05. RESULTS: Improvements in the range of motion in the flexion-extension arch, dorsal flexion, radial deviation and grip strength, expressed as percentages of these values for the opposite, unaffected wrist, were statistically significant. The differences in palmar flexion and ulnar deviation were statistically insignificant. Pain relief at rest and during physical activities was statistically significant. At the follow-up examination most patients (87.5%) reported an overall improvement. The difference in overall improvements between the patients with and without partial resection of the posterior interosseous nerve was not statistically significant. DISCUSSION: The advantages of this procedure involve its technical simplicity, maintenance of wrist motion, satisfactory grip strength and pain relief, and a relatively low occurrence of post-operative degenerative wrist changes. These changes are not in correlation with functional complaints. CONCLUSIONS: As shown by our results as well as published data, proximal row carpectomy is an effective surgical procedure for the treatment of degenerative arthritis of the wrist for its technical simplicity and favourable functional outcomes. Key words: proximal row carpectomy, SNAC-wrist, SLAC-wrist, avascular necrosis of the lunate, dislocation of the wrist, posterior interosseous nerve resection.

[Wrist arthroscopy]. / Artroskopie zápestí.

BACKGROUND: Pain in the wrist area is quite a frequent lesion. If it is not treated soon enough, it leads to development of degenerative changes which are curable with difficulty. Diagnosing is complicated because it is often difficult to diagnose them by means of radiological methods. Wrist arthroscopy is a method which enables to assess the problem and very often it also helps to solve it with an operation. METHODS AND RESULTS: Authors evaluated 93 wrist arthroscopies performed in their departments during 2004-2005. There were 28 arthroscopies performed due to an acute lesion and 65 arthroscopies due to chronic problems. There were 59 arthroscopic curative interventions performed during the operation and 64 open interventions were indicated on the basis of an arthroscopic examination. CONCLUSIONS: All wrist lesions where the lesion of connective tissues structures is suspected, accompanied with edema and hematoma, should be indicated for acute wrist arthroscopy, even though there is no finding on radiographs. Another group of patients indicated for the acute wrist arthroscopy are young patients with wrist fractures where there is a frequent ligament lesion associated, and patients with persisting ailments, even after radiologically confirmed healing of the fracture when intra-articular pathology can be expected. All patients with pain in the wrist area are indicated for arthroscopy, including those with not obvious cause of pain and with symptoms of arthrosis, because it is possible to evaluate further procedure of the therapy.

[Prognostic impact of matrix metalloproteinases 2,9, and 11 in stromal cells stage I non-small cell lung cancer]. / Prognostický význam matrix metaloproteáz 2,9 a 11 ve stromáilních bunkách I. stadia nemalobunecného karcinomu plic.

BACKGROUND: Matrix metalloproteinases (MMPs) belong to proteolytic enzymes. Degradation of the cell basement membrane and the extracellular matrix is one of their functions. In malignant tumors they can hypothetically contribute to the invasion and metastasis formation. They are mostly produced by stromal cells (fibroblasts and endothelial cells) as a response to the presence of tumor cells. MMP-2 (gelatinase A), MMP-9 (gelatinase B) and MMP-11 (stromelysin 3) are often mentioned in regard to Non-small Cell Lung Cancer (NSCLC). METHODS AND RESULTS: The relation between the expression of the above-mentioned matrix metal-loproteinases in stromal cells and the cancer-related survival in 80 patients after curative resection of NSCLC in stage I according to TNM was studied. The expression of MMP-2 was associated with cancer-related survival but without significant correlation. No correlation was found in MMP-9. There was a statistically near-significant relation between the expression of MMP-11 and cancer-related survival. CONCLUSIONS: The expression of MMP-11 in stromal cells in surgically treated NSCLC patients in stage I appears useful for evaluation of their prognosis.

[Non-union in os scaphoideum and its surgical treatment: overview of literature]. / Paklouby os scaphoideum a jejich chirurgické lécení--prehled literatury.

Authors present an overview of surgical methods used for the treatment of os scaphoideum with a focus on currently most frequent operations. In the period between January 1998 and March 2004, the authors performed 100 operations on the scaphoid bone, of this 54times primary fixation and 46times surgery for non-union in 42 patients. The most frequent method was resection of non-union, implantation of tri-cortical bone graft and internal fixation (17times). This method is considered by the authors optimal in non-unions in the middle third of the bone without signs of avascular necrosis of the roximal pole. In 8 patients with signs of avascular necrosis of the proximal pole and in non-unions in the proximal third, reconstruction was done by vascularized bone graft after Zaidemberg. In case of the finding of a minimal sclerotic line without deformation or shortening of the bone the method of choice was compression of the non-union by a screw (Herbert screw, HBS, Synthes screw) in 8 patients. Intramedullary cancellous bone graft and internal fixation was used in 8 patients. However, the authors do not consider it as an optimal treatment as it does not guarantee preservation of the length of the bone until the healing of the non-union. This surgery was used by the authors only as an alternative when it was not possible to choose another method. Extirpation of the distal scaphoid bone (twice) and proximal carpectomy (twice, of this once together with the dennervation after Wilhelm) were performed in non-unions with marked osteoarthritic changes of the radiocarpal joint. In one patient the proximal pole was excised and replaced by tendon graft. The authors do not have experience in limited intercarpal arthrodesis, but most other authors currently prefer proximal carpectomy to this technically demanding operation.

[Percutaneous osteosynthesis of scaphoid fractures: preliminary results]. / Perkutánní osteosyntéza zlomenin clunkové kosti--predbezné výsledky.

PURPOSE OF THE STUDY: To evaluate the results of percutaneous osteosynthesis of scaphoid fractures and to verify whether this approach is more effective than conservative treatment. MATERIAL: A total of 25 patients were treated by percutaneous osteosynthesis at the Emergency and Accident Department of the University Hospital in Olomouc from March 1, 2002, till March 31, 2003. According to the Herbert classification, five had type A2 fractures, four had type B1 and 16 had type B2 fractures. The surgery was performed at 20.6 days on average after injury. HBS screw (Martin) fixation was used in 22 patients, a 3.5 mm cortical screw and a 4.0 mm cancellous bone screw (Poldi 5 set, Kladno, CZ) were inserted in one and two patients, respectively. The wrist was immobilized with a brace in 11 patients. After a short hospitalization, the patients were referred to an out-patient department for follow-up. METHODS: We evaluated the duration of postoperative immobilization, necessity to initiate assisted rehabilitation, length of follow-up at the out-patient department and the functional outcome. The control group comprised of 43 patients who were treated between March 1999 and December 2001. Only patients with type A, B1 or B2 scaphoid fractures managed conservatively were included. Nine patients were excluded because, during treatment, they were converted to conventional open osteosynthesis through the palmar approach. RESULTS: In the study group, the average postoperative immobilization with a brace was 17 days; assisted rehabilitation was initiated in 50% of the patients and resulted in excellent functional outcomes; the average follow-up was 10.3 weeks. In one patient, the fractured scaphoid failed to heal. In the control group, the average postoperative immobilization was 7.5 weeks; assisted rehabilitation was started in 53% of the patients and 23% reported persistent complaints; the average follow-up was 11.4 weeks. DISCUSSION: To achieve a good outcome of percutaneous osteosynthesis of a fractured scaphoid, it is important to make a precise diagnosis based on CT scan. This approach is suitable for type A2, B1 and B2 fractures. A good outcome of surgery depends on the correct insertion of a screw among fragments in order to achieve adequate compression among fragments. The necessity of postoperative immobilization and its manner and duration are current issues of discussion. CONCLUSIONS: Our preliminary results show that, in indicated fractures types, the percutaneous osteosynthesis of a fractured scaphoid provides better functional outcomes than conservative treatment.

[Importance of neoadjuvant chemotherapy in the treatment of advanced bronchogenic carcinoma]. / Význam neoadjuvantní chemoterapie v lécbe pokrocilého bronchogenního karcinomu.

BACKGROUND: The basic task of induction (neo-adjuvant) therapy is elimination of occult micrometastatic dissemination found in some cases already in localized stages of non-small cell pulmonary cancer (stage I-IIIA NSCLC). An equally important effect is also cytoreduction in primary tumours which have before the local intervention an intact vascular supply. A difficult problem remains the correct selection of patients who from the long-term aspect may profit from such a procedure. MATERIAL AND METHODS: The authors evaluated perspectively aspects of oncological treatment and circumstances of surgical intervention after induction chemotherapy in 81 and 87 patients resp. in stage IIIA NSCLC evaluated before initiated neo-adjuvant chemotherapy. RESULTS: Complete remission was recorded in 4.9%, partial remission in 50.6%, stabilized disease in 23.5% and progression in 21% patients. Down-staging was recorded in 26%, 70.3% patients were indicated for surgery. In the group of 87 patients operated after induction therapy pneumonectomies predominated--41 (46%), only one operated patient died within 30 days after surgery (1.1%), complications were neither frequent nor serious. The median of survival after radical resection is 26 months. CONCLUSIONS: Neo-adjuvant chemotherapy by modern cytostatics is usually well tolerated and creates satisfactory conditions for successful complete resection. The operation proper may be more difficult but need not be associated with serious complications. By this treatment it is probably possible to influence long-term results not only in stage IIIA but to reduce also the risk of a later more remote metastatic dissemination in some patients operated in lower stages of lung cancer. Our present aim is to test parameters which will be able to predict possible failure of induction therapy, and seek factors predicting risk behaviour of the tumour also in lower stages (stage I and II TNM classification).
