Early protected motion after extensor tendon repair

Thirty hands with 50 extensor tendon lacerations, excluding mallet finger injuries, were examined. They were treated with surgical repair followed by immediate motion which included a dynamic splinting and tendon mobilization program. The average follow-up period was 7 months (range, 8 weeks to 2 years). Forty-five of the 50 tendons regained full range of motion (average total active motion, 262 degrees) within an average time of 9 weeks; the remaining 5 tendons had extension lags of < or = 10 degrees. All patients regained at least 93% of their predicted normal strength within 9 to 12 weeks and returned to their previous level of activity in an average of 10 weeks. These results, which include complex lacerations, are an improvement from previously published data. This is probably due to the addition of a tendon mobilization program to dynamic splinting following extensor tendon repair.
