Abstract
We compared decompression of the posterior interosseous nerve (PIN) and len gthening of the distal tendon of the extensor carpi radialis brevis (ECRB) for treatment of tennis elbow in a randomised trial of 28 patients. Fourtee n underwent decompression of PIN and 14, lengthening of ERCB. The groups di d not differ significantly with regard to age, sex and work activities. The average duration of preoperative symptoms was 23 months. The PIN was expos ed in the groove between the brachioradialis and brachialis muscles and dec ompressed at the arcade of Frohse by means of a 1-2 cm incision through the supinator muscle. The ECRB tendon was lengthened by Z-plasty at the dorsil ateral aspect of the forearm. No postoperative complications occurred. The outcome after the primary operation was successful in 50% of the PIN group and in 43% of the ECRB group. Four of the 5 patients with a poor outcome we re reoperated in the former,group and 3 in the latter. The overall outcome after a mean follow-up of 31 months after the primary operation was success ful in 60% of the cases.
