Abstract
The flexor digitorum profundus tendon in 11 digits with division of both flexor tendons in zone 2 was reconstructed with a palmaris longus tendon graft in a two-stage procedure. The distal and proximal fixation of the graft was reinforced with a polyester mesh sleeve placed around the ends of the graft during stage 1. All digits were mobilized with a combination of active extension and active and passive flexion within 3 days of the second stage. There were three ruptures, one due to faulty technique and two due to falls on outstretched hands during alcohol intoxication and football. Excluding the ruptures, the mean active composite distal and proximal interphalangeal joint range of motion 6 weeks and 6 months post-operatively was 141° and 136° respectively. The results indicate that palmaris longus tendon grafts can survive and heal during early active mobilization, with few or no adhesions of functional significance. The techniques described here represent one possible approach to the safe implementation of early active mobilization after tendon grafting procedures.
