A Simplified Modification of the Henderson Extensor Carpi Ulnaris Opposition Transfer.

PURPOSE: There are several potential donor muscle-tendon units for a thumb opposition transfer. The extensor carpi ulnaris (ECU) is useful when the more usual donor units are not available. The technique and results of a simplified ECU opposition transfer elongated with a free tendon graft are described. METHODS: Ten ECU opposition transfers were performed using this modification of Henderson technique in 5 adults after complex trauma, 3 adults with median and ulnar nerve palsies, and 2 children with congenital hand differences. RESULTS: Seven patients achieved a Kapandji opposition score of 6 to the distal phalanx of the small finger, and 3 patients achieved a Kapandji score of 5 to the distal phalanx of the ring finger. None of the patients required a secondary tenolysis or developed a radial deviation imbalance of their wrist. CONCLUSIONS: This modification of the Henderson technique using ECU elongated with a free tendon graft and inserted directly and only into the abductor pollicis brevis tendon is an effective method of restoring opposition to the thumb, especially when other conventional donor muscle-tendon units are not available. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic V.

Minimally invasive technique for release of Dupuytren's contracture: segmental fasciectomy through multiple transverse incisions.

BACKGROUND: A multitude of operative approaches have been described for treatment of Dupuytren's contracture. A less-invasive technique of segmental fasciectomies performed through multiple small transverse incisions is presented. METHODS: Seventy-three digits in 37 patients were treated with segmental fasciectomies. The results of 34 digits in 14 patients are described with subsequent follow-up longer than 2 years. RESULTS: Metacarpophalangeal joint extension improved from a mean of 32.5° to 2.2°, while proximal interphalangeal joint extension improved from 22.9° to 4.1°. Patients subjectively rated their surgical outcomes as excellent or good in 91.2% of cases. No recurrence of the disease was noted, though extension of the disease to adjacent digits was observed in three patients. CONCLUSIONS: Though this approach is technically demanding and requires the help of a skilled assistant, this preliminary study supports our contention that this less-extensive procedure allows excellent correction of contractures; results in mild postoperative pain; and permits a rapid return of finger flexion with satisfactory long-term results so far at 2-years follow-up.

Long term results of radial tunnel release--the effect of co-existing tennis elbow, multiple compression syndromes and workers' compensation.

SUMMARY: Surgical decompression of radial tunnel syndrome (RTS) remains controversial because the results are unpredictable. This study is a retrospective analysis of the long term outcomes of RTS release and a comparison of our findings with previous studies. Thirty-three extremities in 31 patients underwent decompression for radial tunnel syndrome between 1994 and 2003, of which 27 extremities in 25 patients were available for long term follow up after an average of 57 months (range 16 to 106 months). Outcomes were evaluated using the criteria of Ritts et al. (1987). For 16 patients (18 of 27 extremities), the outcome was rated as good (67%), for four patients (four extremities) as fair (15%), and for five patients (five extremities) as poor (18%). The outcome was better in patients with simple RTS (86% good results) compared with patients with additional nerve compression syndromes (57% good results), or patients with coexisting lateral epicondylitis (70% vs 43% good results), or patients who were receiving workers' compensation (73% vs 58% good results). One-third of patients still had moderate or severe disability which affected their ability to work, but 82% had relief of their pain. Surgical decompression is therefore beneficial for simple RTS, but may be less successful if there are co-existing additional nerve compression syndromes or lateral epicondylitis or if the patient is receiving workers'compensation.
