The modified Kleinert splint in zone II flexor tendon injuries

The Kleinert controlled passive mobilisation splint has been modified to increase the passive range of motion of the proximal and distal interphalangeal joints to near normal. 12 fingers with complete divisions of both flexor tendons in Zone II treated by this method have been reviewed after six months. Nine regained full motion and two good motion while one, with an associated crush compound fracture of the proximal phalanx, had a poor result. The increased mobilisation did not adversely affect wound healing or associated repair of digital nerves.
