Modified Lateral Approach of the Elbow for Surgical Release and Synovectomy.

Elbow stiffness is a common reason for consultation. In recent years, arthroscopic techniques in elbow surgery have progressed, but there are still some contraindications to performance of arthroscopic synovectomy and release in this joint (elbows with anatomic deformity after multiple procedures, malunion, presence of osteosynthesis material, severe stiffness of >80 degrees, instability, or previous transposition of the ulnar nerve). Therefore, knowledge of a safe and reliable open approach to achieve elbow release and/or synovectomy is essential. We report the technical details of the modified lateral approach between extensor carpi radialis brevis and longus muscles, as well as the clinical results of 43 elbow release and/or synovectomy procedures, illustrating its feasibility. The modified lateral approach, providing visual control of the radial nerve and good anterior exposure of the elbow joint, is detailed. From 1994 to 2016, this approach was used in 43 release and/or synovectomy procedures of the elbow in 41 patients, 30 men and 11 women, with a mean age of 40.56 years (range, 17 to 84 y). Using this procedure, 38 elbows (93%) recovered full extension and 5 subtotal extension with an average deficit of 11 degrees (range, 5 to 20 degrees). All elbows were stable. No neurological complications were reported. The modified lateral approach preserves the insertion of the lateral epicondyle muscles that are major dynamic stabilizers and reduces the risk of instability. Initially described for the treatment of radial tunnel syndrome, it should also be recommended for elbow release and synovectomy.

Results of surgical treatment of De Quervain's tenosynovitis: 80 cases with a mean follow-up of 9.5 years.

INTRODUCTION: Surgery is indicated in De Quervain's tenosynovitis only after failure of medical treatment, often due to individual anatomical variants. We use Le Viet's technique, to avoid tendon instability. The aim of the present study was to evaluate long-term results, with the hypothesis that this surgical technique is reliable, providing lasting results. PATIENTS AND METHODS: All patients operated on between 1993 and 2015 were included, and results were assessed by telephone questionnaire at a minimum 1-year's follow-up. Surgical technique was systematically as described by Le Viet, with subcutaneous fixation of the retinaculum flap. Any anatomical variants were specified. In 26 cases, a concomitant pathology was treated in the same step. In addition to demographic data, the study looked for: pain on VAS, functional impairment, tendon dislocation, and satisfaction. RESULTS: There were no intra- or immediate postoperative complications. Of the 89 patients, 74 (80 wrists) were successfully recontacted: 68 women and 6 men, with a mean age of 48.5 years (range, 19-71 years). The 15 patients lost to follow-up showed initial progression comparable to the rest of the population. A supernumerary septum was found in 50 cases, and an abductor pollicis longus tendon with multiple slips in 35 cases. There were no recurrences. Functional impairment was absent in 68 wrists, moderate in 8 and significant in 4, including 3 with associated diseases. Mean VAS was 0.76 (range, 0-10). No patients reported tendon dislocation or neuroma. Patients were very satisfied in 72 cases, satisfied in 6 and dissatisfied in 2 cases with associated diseases. DISCUSSION: Results in the present series, with a mean follow-up of 9.5 years, were favorable, with total regression of functional impairment in 85% of cases and a satisfaction rate of 97.5%. There were no cases of tendon dislocation, neuroma, or recurrence. Residual problems were all related to associated diseases, whether pre-existing or with subsequent onset. CONCLUSION: Le Viet's technique gives reliable, lasting results without complications or recurrence. LEVEL OF EVIDENCE: IV, retrospective study.
