Early active mobilisation following flexor tendon repair in zone 2.

In a prospective study, 114 patients with 138 zone 2 flexor tendon injuries were treated over a three-year period. Early active mobilisation of the injured fingers was commenced within 48 hours of surgery. 98 patients (86%) were reviewed at least six months after operation. Using the grading system recommended by the American Society for Surgery of the Hand, the active range of motion recovered was graded excellent or good in 77% of digits, fair in 14% and poor in 9%. Dehisence of the repair occurred in 11 digits (9.4%) and in these an immediate re-repair followed by a similar programme of early active mobilisation resulted in an excellent or good outcome in seven digits.
