Does median nerve translate pre- and postoperatively in carpal tunnel syndrome?

OBJECTIVES: This study aims to evaluate the distance between the median nerve and the hook of the hamate pre- and postoperatively in patients with carpal tunnel syndrome and to investigate the efficiency of magnetic resonance imaging in diagnosis and postoperative follow-up. PATIENTS AND METHODS: Median nerve decompression was performed by releasing the carpal tunnel in 15 patients (4 males, 11 females; mean age 51 years; range, 41 to 66 years) with carpal tunnel syndrome. The shortest distance between the median nerve and the hook of the hamate was measured with magnetic resonance imaging preoperatively and at three months after the operation and radial and ulnar translations were assessed. Findings were compared to those of a control group of 15 subjects (5 males, 10 females; mean age 52.2 years; range, 40 to 65 years). RESULTS: Median nerve shifted ulnarwards in patients with carpal tunnel syndrome. An intragroup evaluation of five patients with thenar atrophy revealed that as disease severity increased, the degree of the nerve's medial translation increased. Compared to preoperation, the median nerve significantly shifted to the radial side after decompression. CONCLUSION: In carpal tunnel syndrome patients, we observed significant ulnar translation of the median nerve and lateral translation after releasing the carpal tunnel. Magnetic resonance imaging may be used to establish a diagnosis and to assess operation success in advanced carpal tunnel syndrome patients who may recover slowly postoperatively.

Endobutton Fixation Technique for Multifragmented Coronoid Fractures.

Coronoid fractures commonly occur in a part of unstable elbow fractures. Stable coronoid fracture fixation is important for early elbow motion. It may be difficult to fix multifragmented coronoid process fractures with loose capsular attachment. Thus, we demonstrated the endobutton suspensory technique to fix the anterior coronoidal fragments due to its suspensory effect providing capsular attachment. This technique allows stable fixation to the small multifragmented coronoid fractures with early range of motion.

Lower extremity rotational deformities and patellofemoral alignment parameters in patients with anterior knee pain.

PURPOSE: Anterior knee pain is a common musculoskeletal condition amongst young adult population. Lower extremity structural factors, such as increased femoral anteversion and lateral tibial torsion, may contribute to patellofemoral malalignment and anterior knee pain. The aim of this study was to evaluate the lower extremity structural factors and related patellofemoral alignment parameters that play a role in the aetiology of anterior knee pain. METHODS: This study involved three groups: patients with unilateral symptomatic knees (n = 35), asymptomatic contralateral knees in the same patients and a control group (n = 40). All subjects were physically examined, and Q-angles were measured. The lower extremities of all subjects were imaged by a very low-dose CT scan, and the symptomatic knees of patients were compared with their asymptomatic contralateral knees and with the healthy knees of controls regarding femoral anteversion, tibial torsion, sulcus angle, patellar tilt angle and lateral patellar displacement. RESULTS: Regarding the Q-angle, femoral anteversion and lateral tibial torsion, no significant differences were found between the symptomatic and asymptomatic knees, whereas significant differences were found between the symptomatic knees and controls. The symptomatic group demonstrated significantly greater sulcus angle only in 30° of knee flexion than did the controls. CONCLUSION: Patients with unilateral anterior knee pain may have similar morphology at their contralateral asymptomatic lower extremity, and different morphology compared with healthy controls. Lower extremity rotational deformities may increase the risk of anterior knee pain; however, these deformities alone are not sufficient to cause knee pain, and may be predisposing factor rather than a direct aetiology. LEVEL OF EVIDENCE: Diagnostic study, Level III.

Effect of Ankaferd blood stopper® on tendon healing: an experimental study in a rat model of Achilles tendon injury.

OBJECTIVES: This in vivo study aims to investigate the effects of Ankaferd Blood Stopper® (ABS) which is a recently developed topical hemostatic agent on tendon healing using a rat Achilles tendon injury model. MATERIALS AND METHODS: Twelve male Wistar-Albino rats were used in the study. Right legs of the rats were assigned as the study group, and left legs were assigned as the control group. Under anesthesia, bilateral Achilles tendon injuries were created and repaired surgically. To the surgical sites, 1 mL of ABS for the right side and 1 mL of serum physiologic solution for the left side were applied. Animals were euthanized on the 21st postoperative day, and tendon samples were collected from the extremities. Histological analyses were performed according to the semiquantitative tendon scoring system (Bonar Scale). RESULTS: Total tendon healing scores were significantly poorer in the study group compared to the control group. Although there were no significant differences between the groups in terms of tenocyte morphology, degree of ground substance staining, and vascularity, the collagen morphology scores were significantly poorer in the study group. CONCLUSION: In our study, application of ABS had histologically negative effect on tendon healing in rats. However, further biomechanical and immune histochemical studies are required to support these results.

Management and Prognostic Factors for Delayed Reconstruction of Neglected Posterior Shoulder Fracture-Dislocation.

INTRODUCTION: Posterior fracture-dislocations of the shoulder are rare conditions. Misdiagnosis can occur in 50% - 80% of the patients. Due to the size of the lesion, stability of the joint could not be achieved with transfer of subscapular tendon or tuberosity. CASE PRESENTATION: A 54-year-old male patient was referred to our hospital with a neglected posterior shoulder fracture-dislocation. Functional results of the patient, and technical informations were explained in this case report. The reverse Hill-Sachs lesion involved 40% of the articular surface. Depressed and malunited fragment was elevated, and fixated to the humeral head. CONCLUSIONS: Glenohumeral joint reduction with reconstruction of the humeral head seems to be possible even in a neglected locked posterior shoulder fracture-dislocation. If the depressed osteochondral fragment is still spheric, signs of the avascular necrosis are absent on CT, and malunion of the fragment has occurred, it is quite possible to reconstruct the head. Although results of the case are good, it is worthwhile to follow these patients for long-term complications.

Arthroscopic synovectomy in the treatment of functional ankle instability: outcomes and gait analysis.

BACKGROUND: Natural consequence of repetitive ankle sprains is the chronic ankle instability. Objective of this study was to clarify the gait patterns of functional ankle instability (FAI) patients after arthroscopic synovectomy, but also assessment of postoperative recovery. PATIENTS AND METHODS: Arthroscopic synovectomy was performed to 14 FAI patients with history of unilateral repetitive ankle sprains, pain, and subjective sensation of instability. At a mean 54 months of follow-up (27-84), clinical assessment was conducted with respect to pain, number of ankle sprains, and American Orthopaedics Foot and Ankle Society (AOFAS) scores. Gait analysis was conducted to determine the temporospatial, kinetic and kinematic parameters at the last follow-up. RESULTS: Mean AOFAS scores increased from 68 (range 55-75) to 89 (range 77-100) points (P < 0.01). Mean ankle sprains was 13 in a period of 23 (range 14-48) months (0.58 per month) and decreased to three sprains in a mean time period of 54 months (0.053 per month) (P < 0.01). Mean preoperative and postoperative VAS scores were 8.0 and 2.9, respectively (P < 0.01). During gait analysis, no significant differences were found in ankle joint, including foot progression angles, ankle dorsi-plantar flexion degrees and ground reaction forces (P > 0.01). Among temporospatial parameters, only double support time showed a significant difference (P < 0.01). All patients were satisfied from the procedure and returned to their previous activity level. CONCLUSION: Improved long-term clinical results and scores were obtained in our patient group when compared with the preoperative scores. Also, three-dimensional gait analysis showed that the involved ankles demonstrate similar gait patterns to the uninvolved ankles in patients with FAI.

Soft-Tissue Mallet Injuries: A Comparison of Early and Delayed Treatment.

PURPOSE: To compare the results of early and delayed extension orthosis fabrication in closed tendinous mallet injuries. METHODS: Between March 1992 and May 2011, 45 patients with isolated closed tendinous mallet finger injuries were treated with orthosis fabrication. The patients were classified into 2 different groups based on their date of presentation. Group 1 consisted of 28 patients who presented within 2 weeks of sustaining the trauma, and group 2 consisted of 17 patients who received treatment beginning between 2 and 4 weeks after sustaining the trauma. During the final assessments, the patients were assessed clinically using the Crawford classification scale and satisfaction ratings. RESULTS: The mean delay between initial injury and presentation to our center was 3 days (range, 1-14 d) in group 1 and 19 days (range, 15-30 d) in group 2. There were no significant differences between the groups regarding their ages, initial extension lag, and arc of flexion. According to the Crawford classification criteria, 72% of the patients in group 1 had excellent results, and 59% of the patients in group 2 had excellent results. There was no significant difference between the groups. CONCLUSIONS: The treatment results of patients with different presentation times have been reported for heterogeneous groups of osseous and nonosseous mallet finger injuries. Our results suggest that conservative management of tendinous mallet finger injuries that have been neglected for 2 to 4 weeks can be treated as well as those injuries in patients presenting within the first 2 weeks of injury with low long-term complication rates. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Comparison of two different measurement methods to determine glenoid bone defects: area or width?

BACKGROUND: This study compared two different techniques that have been used to measure the glenoids of patients with recurrent anterior shoulder dislocation. METHODS: We analyzed 36 patients who had received arthroscopic Bankart repair for anterior shoulder instability. Retrospectively, 3-dimensional computed tomography images of both shoulders were available for these patients. Two measurement methods were compared to determine the glenoid defects. One of these techniques is based on linear measurement, previously defined as the glenoid index. The other method is based on surface area measurement. Subsequently, 3 more diameters and the average values obtained from these diameters were compared with the surface measurement method. Pearson correlation coefficient (r) was assessed to determine the relationship. RESULTS: There was an almost perfect relationship between measurement methods when the defect area was less than 6% of the inferior glenoid circle (r, 0.915; P < .001). This relation decreased and the difference became more pronounced (r, 0.343; P = .657) when the bone loss exceeded 14% of the inferior glenoid circle. The highest correlations with the actual defects were the average values obtained from 4 different diameters (r, 0.964; P < .001) and the 4-o'clock position of the single diameter measurements (r, 0.860; P = .001). In addition, 11 patients had crescent-like defects, demonstrating a relatively low correlation between the measurement methods (r, 0.679; P = .021). CONCLUSION: Although the best correlation was achieved from average values obtained from different diameter positions, in practical use, we advise a linear measurement to estimate the glenoid bone loss at the 4-o'clock position to achieve a high correlation between the measurement techniques.

The effect of platelet-rich plasma on osteochondral defects treated with mosaicplasty.

PURPOSE: This study investigated the efficacy of platelet-rich plasma (PRP) on articular surfaces on which the mosaicplasty technique was performed. Our hypothesis was that PRP can accelerate the osseointegration process and enhance the quality of articular integrity after the mosaicplasty procedure. METHODS: Standard defects were created in the femoral groove of both patellofemoral joints of 12 New Zealand rabbits. PRP solution was placed inside the defect before fixation of the osteochondral autografts and injected inside the involved joint after capsular closure of the tested knees. The contralateral knees served as the control sides. The animals were euthanized three or six weeks after mosaicplasty, and both limbs were assessed according to Pineda's histological grading scale. Significance level was set at p ≤ 0.05 a priori, and the Mann-Whitney U test was used for statistical analysis. RESULTS: Histologic findings at the interface between the transferred autograft and the original cartilage revealed better integration of the adjacent surfaces in the mosaicplasty with PRP group three weeks after the procedure; the difference was significant (p < 0.05). However, no significant difference in the transition zone was observed between the groups six weeks after the experiment (p = 0.59). CONCLUSIONS: Our animal model showed that adjunctive use of PRP produced a better healing response and resulted in superior histological scores after three weeks compared with the mosaicplasty-only procedure. Interpretation of our results is important in terms of rapid return to previous activity levels. Thus, application of PRP can represent a valid therapeutic option for improving the efficacy of mosaicplasty by stimulating the local healing response.

Patients with black hip and black knee due to ochronotic arthropathy: case report and review of literature.

Ochronotic arthropathy is a manifestation of longstanding alkaptonuria. With increasing age, an accumulation of pigment deposits of homogentisic acid in the joint cartilage results in ochronotic osteoarthritis. We present a case of a 62-year-old female who underwent staged left uncemented total hip and right cemented total knee arthroplasty for osteoarthritis secondary to ochronosis.

Short-term functional outcomes of first metatarsophalangeal total joint replacement for hallux rigidus.

BACKGROUND: Although metatarsophalangeal (MTP) arthrodesis has been advocated by many authors, implant arthroplasty appears to be successful option in advanced hallux rigidus (HR). The aim of our study was to evaluate the early results of the ToeFit-Plus prosthesis for the treatment of HR. METHODS: Between December 2007 and January 2011, a total of 26 toes of 24 patients with MTP arthritis of the great toe were treated with ToeFit-Plus implant. The average follow-up time was 29.9 (range: 25 to 62) months. All patients were evaluated clinically and radiographically. Postoperative satisfaction and function were scored according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Pain was assessed with the use of a visual analogue scale. RESULTS: Mean preoperative AOFAS score improved from 42.7 (range: 36 to 59) to 88.5 (range: 59 to 98) at the final follow-up (P < .01). Preoperative average visual analogue scale pain scores improved from 7.4 preoperatively to 1.9 at the final follow-up (P < .01). The average MTP joint range of motion improved from 25.9 degrees preoperatively to 53.8 degrees at the final follow-up. No radiologic loosening was found, but radiolucency was observed in 2 patients with this implant. No revision was required for any of the patients during the follow-up period. CONCLUSIONS: This total first MTP joint prosthesis yielded good functional outcome and high patient satisfaction level with low early complication rate. Preservation of joint movement and good pain relief with early mobilization were the advantages of this procedure. Salvage arthrodesis remains an option if future revisions are indicated. LEVEL OF EVIDENCE: Level IV, retrospective case series.

Forearm compartment syndrome of a newborn associated with extravasation of contrast agent.

Extravasation of contrast agents is a possible complication of imaging studies. Although extravasations typically cause minimal swelling or erythema, they can lead to compartment syndrome when the volume of extravasation is high. In this article, we will present an exceptional case where an insignificant amount of contrast agent extravasation led to a forearm compartment syndrome in a newborn, who was treated with an extended fasciotomy. We would like to emphasize the preventive techniques and treatment options of this iatrogenic complication in newborns. Close followup of the patient by the nurses, awareness of the parents and the personnel in the radiology department are the most important preventive measures in this extremity-threatening complication. Forearm compartment syndrome due to contrast agent extravasation may progress more rapidly in newborns even with smaller amounts of extravasation and prompt recognition of the pathology and immediate intervention are unevitable.

Diagnosis of hyperostosis of the medial calcaneal tubercle similar to a heel spur.

Calcaneal osteochondromas are rare conditions. To our knowledge, we present the first report of a calcaneal osteochondroma in an adolescent patient that was surprisingly similar to a heel spur, and, in addition, symptoms due to compression of the medial plantar nerve were present.

Giant cell tumor of second and third metatarsals and a simplified surgical technique: report of two cases.

Giant cell tumor (GCT) is a rare benign tumor that often arises in tendon sheath as well as long bones of the lower extremity in adults, although localization in the metatarsus is rare. In this report, the authors describe the rare case of GCT localized to the third metatarsal GCT in a skeletally mature 17-year-old girl, and also describe the results of distal metatarsal resection with Kirschner wire stabilization for the treatment of this condition.

Is there any correlation between the preoperative parameters and correction loss in patients operated for hyperkyphosis?

OBJECTIVES: Preoperative, postoperative, and latest follow-up data of sagittal balance and spinopelvic parameters of our patients treated surgically for hyperkyphosis were evaluated retrospectively, to determine whether there is any correlation between the preoperative pelvic incidence and postoperative correction loss. METHODS: Totally 33 patients (18 females) who were operated for hyperkyphosis and, were reached at the latest follow-up were included in the study. Age at operation, gender, date of operation, etiology and level of the deformities, instrumentation, and graft types were noted in detail. The kyphosis angles were measured by the Cobb method. The preoperative and postoperative spinopelvic parameters (pelvic incidence, sacral slope, and pelvic tilt) were recorded. RESULTS: The average follow-up was 4 years (range 3-8 years). The mean age at operation was 21 years (range 14-40 years). Scheuermann kyphosis was diagnosed as the etiological factor in 18 patients (53%). The mean preoperative kyphosis angle was 76° (range 55-98°), which decreased postoperatively to 38° (range 20-55°) (p<0.05). The mean kyphosis angle two years postoperatively was 41° (p>0.05). Preoperative and latest follow-up spinopelvic parameters were also not significantly different. Furthermore, no correlation could be found between the age at operation, instrumentation level, spinopelvic parameters, and correction loss. CONCLUSION: There is no correlation between the preoperative pelvic incidence and postoperative correction loss in patients treated surgically for hyperkyphosis. Further studies with larger sample size and longer follow-up should be conducted.

[Long-term results of conservative treatment for thoracolumbar compression fractures]. / Torakolomber omurga kompresyon kiriklarinda konservatif tedavinin uzun dönem sonuçlari.

OBJECTIVES: We evaluated the radiologic and clinical outcomes of conservative treatment for thoracolumbar compression fractures. METHODS: Forty-three patients (28 males, 15 females; mean age 39 years; range 24 to 54 years) were treated conservatively for 47 thoracolumbar compression fractures. All the patients were assessed by plain radiograms and computed tomography. According to the Denis classification, there were eight type A, 20 type B, 12 type C, and seven type D fractures. Involvement was at L1 in 30, L2 in five, and T12 in 12 fractures. There were no neurological deficits. Treatment involved use of a body cast for two months, followed by a thoracolumbosacral orthosis for four months. Radiographically, local kyphosis angle and sagittal index were measured before treatment, after casting, and at the final follow-ups. Pain and functional scales proposed by Denis et al. were also utilized. The mean follow-up was 7.5 years (range 6 to 11 years). RESULTS: The mean local kyphosis angle and sagittal index were measured as 12.6 and 13.7 degrees before treatment, and 5.9 and 7.0 degrees after casting, respectively (p<0.05). However, both did not differ significantly from the baseline at the final measurements (12.7 and 13.9, respectively; p>0.05). The mean pain and functional scores were 1.4 and 1.6, respectively. Four patients had moderate to severe back pain despite mean kyphosis angles of 12 (baseline), 13.5 (after casting), and 14.8 (final). Two patients required substitution of the body cast for orthosis due to excessive sweating, and three patients received local treatment for skin problems secondary to the use of orthosis. CONCLUSION: If the kyphosis angle is less than 30 degrees, compression fractures are supposed to be stable to be treated conservatively with satisfactory clinical results. Functional results seem to be unaffected from the fact that casting does not improve radiographic parameters in the long-term.

[Surgical treatment of isolated post-traumatic subscapularis tendon ruptures]. / Travma sonrasi olusan izole subskapularis tendon yirtiklarinin cerrahi tedavisi.

OBJECTIVES: We retrospectively evaluated the functional results of patients who were treated surgically for post-traumatic isolated subscapularis tendon ruptures. METHODS: The study included six patients (5 males, 1 female; mean age 63.3 years; range 53 to 70 years) who were operated on for isolated post-traumatic subscapularis ruptures. The mean interval between the development of symptoms due to trauma and operation was 4.3 months (range 1 to 9 months). Mechanism of injury, complaints, clinical findings, imaging methods, arthroscopic and surgical findings, repair techniques, and postoperative follow-up data were assessed. Evaluations were based on physical assessment, radiographic examination, and the UCLA (University of California at Los Angeles) score. The mean follow-up was 29.6 months (range 13 to 53 months). RESULTS: The mean UCLA score was 11.3 (range 9 to 14) preoperatively. It increased to 25.8 (range 12 to 31) postoperatively (p<0.05). The results were good in four patients, fair in one patient, and poor in one patient. Magnetic resonance images obtained in five patients at the final follow-up showed total rupture in the patient with poor outcome, partial rupture in the patient with fair outcome, and maintenance of tendon integrity in the remaining patients. CONCLUSION: A careful clinical examination may enable the diagnosis of subscapularis tendon ruptures. Magnetic resonance imaging may provide additional information. In most patients, the repair of the tendon is possible by proper protection of the axillary nerve and appropriate mobilization.
