A capsular-based vascularized distal radius graft for proximal pole scaphoid pseudarthrosis.

PURPOSE: To evaluate the clinical results of the application of a capsular-based dorsal distal radius vascularized bone graft in scaphoid proximal pole nonunions. METHODS: Thirteen patients with symptomatic nonunion at the proximal pole of the scaphoid (10 with avascular necrosis) were treated and reviewed retrospectively. The vascularized bone graft was harvested from the distal aspect of the dorsal radius and was attached to a wide distally based strip of the dorsal wrist capsule. It was inserted press-fit into a dorsal trough across the nonunion site after scaphoid fixation with a Herbert screw. RESULTS: After a mean follow-up period of 19 months 10 of the 13 nonunions (8 of the 10 with avascular necrosis) achieved solid bone union. No complications other than the 3 persistent nonunions occurred. CONCLUSIONS: Results of the use of a capsular-based vascularized bone graft from the distal radius for proximal pole scaphoid nonunions compare favorably with the results of pedicled or free vascularized grafts. It is a simple technique that eliminates the need for dissection of small-caliber pedicle or microsurgical anastomoses. No donor site morbidity was observed. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

Bipolar hemiarthroplasty for chronic rotator cuff tear arthropathy.

Massive rotator cuff tears associated with glenohumeral arthritis are currently an unsolvable clinical entity. We review our series of 14 patients with rotator cuff tear arthropathy (RCTA) who underwent a bipolar prosthesis of the shoulder. The average follow up was 27.8 months (range, 24-48 months), and the average age was 71 years (range, 57-84 years). Of these 14 patients, 9 were men and 5 women. None of these patients had undergone previous shoulder surgery, and all patients underwent conservative treatment that failed to improve their symptoms or range of motion. Preoperatively, the average active forward flexion was 30 degrees, active external rotation was 10 degrees, and the American Shoulder and Elbow Society (ASES) score was 25 points. Postoperatively, the average active forward flexion improved to 88 degrees, active external rotation increased to 37 degrees, and the ASES score improved to 80 points. Of the 14 patients, 12 stated that they had no pain with activities of daily living. Two patients continued to have moderate pain in everyday activity.

Radial tunnel syndrome.

True neurogenic radial tunnel syndrome is an uncommon condition caused by entrapment of the radial or posterior interosseous nerve. It is a subjective pain syndrome with rare motor findings. The chief complaint is generally pain at the dorsal aspect of the upper forearm; any weakness is usually secondary to pain. Electrodiagnostic studies are unreliable in radial tunnel syndrome. Although previous studies have found a high rate of good results, the authors believe that a high rate of morbidity is associated with both the disease and its treatment. Based on their results they suggest that great caution has to be taken before performing radial tunnel release, and strict adherence to the indications should be noted during the preoperative examination. A trial of nonsurgical treatment is warranted in all patients. Patients who do not respond or continue to progress despite conservative treatment are candidates for surgical decompression. Based on the recent literature, surgical decompression leads to approximately 60 to 70% good and excellent results.
