Classification of vascularized fibular flap hypertrophy based on X-ray evaluation.

OBJECTIVE: The aim of this study was to analyze and classify hypertrophy seen in vascularized fibula flaps used for reconstruction of tubular bone defects. METHODS: Thirty-three patients who underwent a vascularized fibula flap for the reconstruction of massive bone defects of the upper or lower extremity long bones were retrospectively reviewed and included in this study. There were 24 lower extremities (21 tibial and 3 femoral) and 9 upper extremities (4 humeral, 2 radial and 3 ulnar) reconstructions in this series. The mean age was 32.7 (range= 10- 59) years. The mean length of bony defect following initial debridement was 10.3 (range= 4-25) cm. The fibula was inserted as a single strut in 29 patients, and as a double barrel construct in 4 patients. The degree of fibular hypertrophy was calculated based on anteroposterior (AP) and lateral X-ray measurements of fibular flaps at an average postoperative period of 52 months. The difference in thickness between the initial and final x- ray measurements were expressed as percentage of hypertrophy. The variances seen in this period were defined and classified. RESULTS: When bony consolidation of the 33 cases were examined in detail, 4 different modes of flap hypertrophy were defined: type 0- absence of hypertrophy, type 1- limited hypertrophy, type 2- marked hypertrophy triggered by stress fracture, and type 3- massive hypertrophy enhanced by peripheral bone production. CONCLUSION: Fibular hypertrophy follows different modes based on vascularity of the flap, amount of stress imparted on the flap, site of reconstruction, and whether the periosteal sleeve is retained at the reconstruction site. Determination of these factors at the initial period may help the surgeons to predict the final hypertrophy that will be seen at the end of flap maturation Level of Evidence: Level IV, Therapeutic Study.

The results of delayed open reduction and internal fixation in chronic bony mallet finger injuries.

OBJECTIVES: The aim of this study was to evaluate the functional results of delayed open reduction and Kirschner wire (K-wire) fixation procedures in patients with delayed presentation of bony mallet finger. PATIENTS AND METHODS: Between February 2009 and November 2019, a total of 19 patients (15 males, 4 females; median age: 24.8 years; range, 14 to 47 years) who were diagnosed with a delayed bony mallet finger and treated with dorsal block pin, direct pinning, or the umbrella handle technique were retrospectively analyzed. The Crawford criteria were used to evaluate the outcomes. The degrees of range of motion (ROM) were measured by a goniometer. RESULTS: The median time from injury to surgery was 41 (range, 28 to 90) days. The median DIP joint extension limitation was 7.63 (range, 0 to 40) degrees and the median ROM of the DIP joint was 66.3 (range, 20 to 90) degrees. There was no statistically significant difference in the postoperative ROM, compared to the uninjured side (p>0.05). The Crawford score was excellent in 11, good in four, fair in three, and poor in one patient. Bone union was achieved in all patients. CONCLUSION: Delayed open reduction and K-wire fixation of chronic bony mallet finger injuries yield successful functional outcomes with low complication rates. Extension lag can be eliminated in most patients by making the joint surface anatomical. The most optimal method should be selected depending on the size of the fracture fragment.

Survival and Comparison of External Bleeding Methods in Artery-Only Distal Finger Replantations.

PURPOSE: If there are no veins available in a distal amputation, an artery-only replantation is performed, and an external bleeding method is commonly used. We conducted a survival analysis in a large series of artery-only replantations and compared 2 different external bleeding methods in artery-only distal replantations: nail matrix or hyponychial area bleeding and pulp skin area bleeding, which we have called the crater method. METHODS: Two hundred twenty-eight artery-only distal finger replantations in 199 patients were included in the study. The replanted digits were divided into 2 groups according to the external bleeding methods. One group (n = 94; 41.2%) included the patients in whom the external bleeding was performed using a traditional nail bed incision and the second group (n = 134; 58.8%) included the patients in whom external bleeding was performed using the crater method. The finger survival rates and postoperative circulatory problems were examined. The impact of the injury mechanism, injury level, and external bleeding method on survival were evaluated. RESULTS: Clinical findings indicating venous insufficiency were observed in 198 (86.8%) replanted fingers. One hundred eighty-two (79.8%) survived, and complete necrosis developed in 46 (20.2%). Viability was maintained in 84% of patients treated with the nail bed bleeding method and 76.9% of patients treated using the crater method. Clean-cut cases had the best results and subzone 3 cases had the worst results. CONCLUSIONS: The artery-only replantation was associated with a 79.8% survival rate. The method of achieving venous outflow did not appear to have an impact on survival. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Umbrella handle technique for fixation of FDP avulsion fracture.

We present the treatment course of a 29-year-old male patient with for a Type 3 FDP avulsion (Jersey's finger) of a fifth finger treated with umbrella handle technique. The patient had a volar base fracture of distal phalanx with dorsal subluxation of DIP joint after a fall. Following open reduction of the FDP avulsion fracture and fixation was achieved with a 0.9 mm one edge hooked Kirschner wire under fluoroscopy control. The straight edge of the wire was driven out in a central position in sterile nail matrix just distal to lunula. The wire was removed at the fifth week when the complete union of the fracture was observed. The patient achieved full flexion in DIP joint without an extension lag.

Reconstruction of extensive pulp defects of the thumb with a radial-based pedicled flap from the index finger.

This article defines a sensate, pedicled heterodigital flap from the proximal radial side of the index finger for reconstructing large soft tissue defects of the thumb. The pedicle consists of the radial digital artery of the index finger. Dorsal sensory branch of proper digital nerve and one of the terminal sensory branches of radial nerve are included in the flap for sensation. The results of 17 consecutive patients at 24 months revealed mean static two-point discrimination of 7 mm at the reconstruction site and 10 patients were able to feel 4 mm at the reconstructed thumb. The mean range of motion of metacarpophalangeal and interphalangeal joints of operated thumbs reached 94% and 66%, the mean grip span reached 96% compared with the uninjured side. The presented flap provided a simple yet favourable alternative for reconstruction of the thumb tip, with thick and durable tissue requiring minimum dissection and donor side morbidity. Level of evidence: IV.

Combined Fractures of the Scaphoid and Distal Radius: Evaluation of Early Surgical Fixation (21 Patients with 22 Wrists).

Introduction The purpose of this retrospective study, is to evaluate the clinical and functional results of early surgical fixation of the ipsilateral distal radius and scaphoid fractures in 22 of 21 patients. Patients and Methods Overall, 22 combined ipsilateral scaphoid, and distal radius fracture treatments between 2002 and 2015 were evaluated. The mean age was 34.9 (range: 19-82) years. One patient had bilateral injuries. In 17 patients the injury was due to a fall from a height, and in 4 patients due to a motorcycle accident. According to the AO classification, there were 2 type B and 20 type C fractures of the distal radius. The volar locking plate fixation technique was applied in 14 wrists, screw fixation technique in 1, external fixation combined with Kirschner wires (K-wire) stabilization technique was used in 3 wrists, and only K-wire pinning technique was used in 4 wrists. All scaphoid fractures were type B (21 type B2, 1 type B1) according to the Herbert-Fischer classification. K-wire fixation was applied in 2 and cannulated screw fixation was performed in 20 fractures. Clinical evaluation was performed with measuring the pinch power, grip power, and range of motions. Functional evaluation was performed using patient-rated wrist evaluation score (PRWE). Results The average follow-up period was 25 (range: 12-97) months. All radius and scaphoid fractures healed. The mean active wrist motions were found to be 45 degrees of flexion, 48.5 degrees of extension, 20 degrees of radial deviation, and 43 degrees ulnar deviation. Mean grip/pinch strengths were 31/8.5 kg. Mean PRWE score was 5.5 (range: 0-8.5). All patients returned to preoperative activity level and can do preinjury jobs. Conclusion Combined ipsilateral fractures of distal radius and scaphoid are complex and rare injuries due to high energy traumas. Stable early primary fracture fixation in these injuries can be expected with good functional results. Level of Evidence Level IV.

Comparison of ultrasound and dorsal horizon radiographic view for the detection of dorsal screw penetration.

OBJECTIVE: The aim of this study was to compare the efficiency of dorsal tangential fluoroscopy and ultrasonography in detecting dorsal screw penetration in distal radius volar locking plate applications. METHODS: Ten cadaveric forearms were operated. The distal four screws were protruded 0, 1 and 2 mm into each of the second, third and fourth dorsal compartments of distal radius. Dorsal horizon views were taken using fluoroscopy. Each radiographic image was evaluated by two orthopedic surgeons who are blinded to procedure. Sonographic evaluations were performed by an orthopedic surgeon blinded to the procedure. Both dorsal horizon view and ultrasonography assessments were noted by the evaluators whether the tip of the screw penetrated or not the dorsal cortex for each compartment. RESULTS: No significant difference was observed on correct detection of 0 mm, 1 mm and 2 mm screw penetrations at second and third compartments. In the fourth compartment, there was no difference with 0 mm and 2 mm penetrations but correct detection accuracy of 1 mm screw penetration was 87% in ultrasonography group and 71% in dorsal horizon view group. CONCLUSIONS: The accuracy of ultrasonography on 1 mm penetration at the fourth compartment is better than dorsal horizon view. However, dorsal horizon view and ultrasonography accuracy is similar for the other compartments and penetration levels. Ultrasonography is a reliable and effective procedure for detection of dorsal screw penetrations. LEVEL OF EVIDENCE: Level III, Diagnostic study.

Techniques and survival incidence for revascularization of degloved fingers.

We report techniques and survival incidence of three subtotally and nine completely degloved fingers in seven patients. We performed end-to-end arterial repairs in seven fingers, vein graft repairs for arteries in two fingers, arteriovenous anastomoses in three fingers. End-to-end vein anastomosis was performed in all fingers. One finger requred re-exploration. Soft tissues in the eight degloved fingers survived completely, two failed completely, and two were partially necrotic. We conclude from our results that following revascularization, the skin from a completely degloved finger skin will survive in approximately two cases out of three. LEVEL OF EVIDENCE: IV.

A new complication in volar locking plating of the distal radius: longitudinal fractures of the near cortex.

OBJECTIVE: The purpose of this study was to document a new complication in volar locking plating of the distal radius. METHODS: Between January 2007 and January 2014, 223 patients were identified from the department's surgical database with retrospective chart and radiographic review. Sixty-eight patients were over 60 years of age. All fractures were operated with Acu-Loc® (Acumed, Hillsboro, OR, USA) wrist volar locking plating systems. Longitudinal fracture lines (LFL) beneath volar plate-extending proximal shafts were documented. Correlations between age groups and LFLs were investigated. Radiographs with LFLs were assessed at final follow-up for the following parameters: volar tilt, radial inclination and radial length. RESULTS: Twenty-eight of 68 patients over age of 60 years had LFLs. Correlation was significant for age groups (p<0.05). The effect of these fracture lines on radiographic parameters was not significant (p>0.05). CONCLUSION: Surgeons should be aware of the complications that may occur with volar locking plates. Understanding of potential complications and their results are important. As a result of aging, thinning, and weakening, the near cortex may become more brittle. When the plate is reduced on the bone with a nonlocking screw, the conical head of diaphyseal locking screws can extend over plate thickness and penetrate the near cortex, acting as a screwing wedge. Additional divergent configuration may promote this effect and crack the cortex.

Ultrasonic Evaluation of the Flexor Pollicis Longus Tendon Following Volar Plate Fixation for Distal Radius Fractures.

PURPOSE: To evaluate with ultrasound the thickness of the flexor pollicis longus (FPL) tendon and its relationship to the volar locking plate after the fixation of distal radius fractures. METHODS: We evaluated 27 type C2 and C3 distal radius fractures with ultrasound to evaluate damage to the FPL tendon after volar plate fixation. The thickness of the FPL tendon and its distance to the volar plate in the involved wrists and to the volar rim in the contralateral uninjured wrist were measured on sonograms taken 12 months postoperatively. Measurements of the involved wrists were compared with those of the intact wrists. RESULTS: The mean plate-tendon distance in the involved wrist was considerably shorter than the mean volar rim-tendon distance in the intact wrist, and the FPL tendon was considerably thicker in the involved wrist than in the intact wrist. CONCLUSIONS: In distal radial fractures treated with volar locking plates, increases in the thickness of the FPL tendon and a consequent decrease in the distance between the tendon and the plate can be determined with ultrasonography. This finding is a warning that asymptomatic tenosynovitis may eventually cause tendon ruptures. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic IV.

A bibliometric analysis of orthopedic publications originating from Turkey.

OBJECTIVE: The objective of this study was to analyze the research productivity originating in Turkey using articles published in the top 40 orthopedic journals according to the Journal Citation Reports for 2013. METHODS: All scientific papers published in English and included in the Science Citation Index Expanded between 1980 and 2013 were analyzed using the "Web of Science". The number of publications per million (PmP) was calculated. All selected journals were analyzed for the numbers of articles, authorships, institutions and 100 most frequently cited papers. RESULTS: From a total of 130,494 articles published worldwide, the United States ranked first according to output. Turkey ranked 14th in the number of orthopedic publications and 26th out of 30 countries in the PmP index. 2012 produced the greatest number of publications worldwide and 2008 for Turkey. Gunal I., Yazici M. and Ozturk C. were the most frequent contributors. Hacettepe University, Istanbul University and Ankara University were the most frequent intuitions among all Turkish publications. The Archives of Orthopaedic and Trauma Surgery was the most frequently published journal in this period with a rate of 16.3%. There was a total of 9,085 (8,765; excluding self-citations) citations of the 1,398 publications published in Turkey until December 2013, with a citation-to-work ratio of 7.47 and an h-index of 34. CONCLUSION: With the newly established universities, as well as training and research clinics, the approach of increasing number of orthopedics and traumatology clinics and specialists to scientific activities would be more fruitful in the light of these data.

Clinical applications of free arterialized venous flaps.

Venous flaps are flaps by which tissue perfusion is accessed through the venous network. Despite originally being questioned due to potential perfusion problems, as the dynamics of tissue perfusion have been more fully comprehended, venous flaps appear to have a far wider range of application than first thought. In our study, we analyzed the clinical results of the applications of free arterialized venous flaps along with the factors that can affect flap survival. Forty-one flaps were assessed retrospectively. Type of the trauma, traumatized area, the time duration between trauma and application of the flap, donor area, type and count of the anastomosis, encountered complications, and flap survival rates were analyzed. Regression and classification trees were used to study the relationship between flap surface area, anastomosis count, and flap survival. Circulatory abnormalities such as early congestion and edema were seen in 53.6% of the applied flaps. A total of four flaps (9.7%) developed necrosis which presented as full thickness in three flaps and partial thickness in one flap. It can be said that there was a weak but positive correlation between the size of the flap area and the number of anastomosis. Although the results of arterialized venous flaps are inconsistent in the literature, those flaps can be preferred as an alternative treatment option in single finger defects where tissue compatibility and cosmetic results are quite impressive. In the meantime, syndactylized venous flaps are the preferred method regarding multiple finger soft-tissue defects.

Syndactylizing arterialized venous flaps for multiple finger injuries.

Multiple soft tissue finger defects in different shapes and locations are usually difficult to manage. Such defects commonly involve tendons and bones. Palmar soft tissue defects may also lead to vascular compromise. In this retrospective report, we report the results of seven patients with multiple soft tissue finger defects that were covered by syndactylizing arterialized venous flaps. Six of the patients suffered hot-pressing machine and crushing injuries, one patient had a rolling belt injury. All patients presented with soft tissue defects on palmar or dorsal sides involving at least two digits. The palmar forearm was donor site for all patients. At least one afferent artery and two efferent veins were selected for the anastomosis. Lengths of afferent and efferent veins were long enough to perform healthy anastomosis outside the injury zone. The afferent vessels were anastamosed to the digital arteries with the largest possible diameter or to the common digital arteries to maximize flow. The efferent veins were anastamosed to dorsal veins. Separations of the digits were performed after three weeks by longitudinal incisions. The mean follow-up period was 12 months. None of our patients suffered a flap loss. Syndactylizing arterialized venous flaps may be used for composite or single tissue reconstruction for multiple finger defects with satisfactory cosmetic and functional outcomes.

Surgical reconstruction in Wassel type IV thumb duplication.

OBJECTIVE: The aim of this study was to review the results of patients with Wassel type IV thumb duplication, treated with a single reconstructive procedure. METHODS: The mean follow-up period was 76.9 months. Objective assessments were carried out using Horii modification of Tada scoring system and ALURRA scoring system. Thumb length, thumb girth, range of motion of metacarpophalangeal (MCP) and interphalangeal (IP) joints and angular deformities at MCP and IP joints were evaluated. RESULTS: The mean ALURRA score was 21 (range; 16-24) and Tada Score 5.25 (range; 2-7). The length of the operated thumb was approximately 95%, the girth 89% and nail width 80% of the non-operated side. The mean range of motion was 75.1% of the unaffected thumb in interphalangeal joint and 80.1% in metacarpophalangeal joint. Metacarpophalangeal joint malalignment had shown statistically significant negative correlation with the scores of Tada, ALURRA and VAS. CONCLUSION: Surgical reconstruction may provide a functional and stable thumb in Wassel type IV thumb duplications. The satisfaction of patients is affected by angular deformity of thumbs and cosmetic outlook.

Traumatic hemipelvectomy: case presentation.

Traumatic hemipelvectomy is a severe, life-threatening injury, mainly occurring due to machinery injury or traffic accident. Few cases have been published in the literature. Treatment requires a rapid, multidisciplinary team approach which will result in the saving of the patient's life. We present the outcome of a male patient with traumatic hemipelvectomy.

Popliteal artery injury associated with blunt trauma to the knee without fracture or dislocation.

Popliteal artery injuries are frequently seen with fractures, dislocations, or penetrating injuries. Concern about arterial injury and early recognition of the possibility of arterial injury is crucial for the salvage of the extremity. This article provides an outline of the diagnostic challenges related to these rare vascular injuries and emphasizes the necessity for a high level of suspicion, even in the absence of a significant penetrating injury, knee dislocation, fracture, or high-velocity trauma mechanism. The importance of a detailed vascular examination of a blunt trauma patient is emphasized.

Limb salvage and amputation in Type 3C tibial fractures.

OBJECTIVE: The aim of this study was to evaluate the results of limb salvage and primary amputation treatments in patients with Type 3C tibia fractures and compare with normative population data. METHODS: Limb salvage was performed in 20 patients and primary amputation in 14 patients with Type 3C tibia fractures between 1993 and 2009. Mean follow-up period was 5.3 years. Treatment times, complications, number of operations and return-to-work status of groups were compared. The Short Form-36 (SF-36) was used to assess quality of life and domains were compared among the patient groups and normative data. RESULTS: Limb salvage patients had longer treatment periods with more operations and complications than the primary amputation group. Return-to-work percentage was 59% in the limb salvage group and 71% in the amputation group. There was no statistical difference in all SF-36 domains for limb salvage and primary amputation patients. Physical functioning, social functioning, limitation due to emotional problems and pain were statistically lower in all patients than in the general population. CONCLUSION: Type 3C tibia fractures treated with both limb salvage and primary amputation have negative effects on quality of life. Patients should be informed about limited functional capacity, pain complications and problems with return-to-work at the end of treatment. In addition, high rates of limb salvage can be achieved with proper conditions in suitable patients.

Complications of distal radius locking plates.

Fixation of distal radius fractures via locking plates is an increasingly popular method. However, these plates include variety of complications, such as flexor and extensor tenosynovitis, tendon injury and intra articular screw or peg penetration. Although they offer superior stability and early mobility, if used improperly; they may cause serious complications related to the implant. Proper use of the implant with strict adherence to the fixation principles and close follow up of patients are very important in order to decrease the rate and severity of complications.

Comparison of dorsal and volar percutaneous screw fixation methods in acute Type B scaphoid fractures.

OBJECTIVE: In this study, we aimed to compare the clinical and functional results of patients treated with dorsal or volar percutaneous screw fixation for acute scaphoid fractures. METHODS: We retrospectively evaluated 27 wrists of 26 patients (24 males, 2 females; mean age: 33.1 years) who underwent dorsal or volar percutaneous screw fixation for acute scaphoid fractures between 2000 and 2009. The dorsal approach group contained 13 wrists and the volar approach group 14 wrists. Splint was removed and wrist exercises initiated on the 10th postoperative day. Pinch power, grip power and range of motion were evaluated using the contralateral wrist as controls. Functional evaluation was performed using the patient-rated wrist evaluation score (PRWE) and Mayo wrist scoring system. RESULTS: According to the Herbert and Fisher's classification system there were 9 B2, 3 B3 and 1 B1 fractures in the dorsal approach group, and 12 B2 and 2 B1 fractures in the volar approach group. Fracture union was achieved in all patients. There was no significant difference between the two groups according to functional and clinical results (p>0.05). All patients returned to their jobs in an average of 4.2 weeks and there was no significant difference between the groups (p=0.437). Wrist flexion was significantly better in the control wrists in both groups (p=0.009). In one patient, the screw was removed due to ongoing pain and asymptomatic screw head displacement in the scaphotrapezoid joint was detected in another. CONCLUSION: The surgical approach does not affect the clinical and functional outcomes in percutaneous screw fixation of Type B scaphoid fractures. Percutaneous fixation is a valuable treatment method for Type B scaphoid fractures as it enables early wrist motion and high patient satisfaction.
