Repair of extensor tendon injuries of the hand

We have presented methods for treating extensor tendon injuries from the interphalangeal joint to the wrist and the musculotendinous junction in the forearm. Early and proper splinting in the treatment of extensor tendon injuries is more important than a specific method of surgical repair. We emphasize the need for prolonged splinting, up to eight weeks in distal injuries. Immobilizing the finger in full extension or hyperextension is necessary at the distal and proximal interphalangeal joints. Correct splinting is mandatory in any method of treatment. Reconstruction of the extensor mechanism is difficult and the results are unpredictable.
