Purpose: Independent FDS action has been cited to be problematic with repair of multiple tendons in zone V owing to adhesion formation between the flexor digitorum superficialis (FDS) and the flexor digitorum profundus (FDP) tendons. Of the several described flexor repair technique the ideal tendon repair should be strong enough to allow for early active motion to minimize adhesion formation and maximize tendon healing. Biomechanical studies have proven the Massachusetts General Hospital (MGH) repair to be strong enough to allow for early active motion. The purpose of this study was to examine the use of the MGH technique for zone V flexor tendon injuries to allow for early protected active motion to achieve independent finger flexion through better differential gliding of the tendons. Methods: We performed a retrospective review of 181 zone V finger flexor tendon repairs for 31 patients performed consecutively over 4 years when early protected active motion protocol was used for all of these patients. We reviewed totals active motion, independent flexion, rupture, and need for tenolysis. These injuries involved 110 FDS and 71 FDP tendons to 110 fingers. The median follow-up period was 22 weeks. Of these 31 patients 21 were men and 10 were women. The average patient age was 29 years. Results: The total active motion for these zone v repairs was 235+/-5 degrees. Overall, 103 of 110 digits attained good to excellent function and 93 of 110 developed some differential glide. One of these patients required a tenolysis. Three repairs ruptured in 1 patient owing to suture breakage that was associated with noncompliance with the dorsal extension block splint. Conclusions: Our retrospective review of 181 consecutive flexor tendon repairs showed that the MGH technique allowed for early protected active motion, which provided good to excellent functional outcomes with 85%, (93/110) developing independent finger flexion at an acceptably low complication risk.
