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.

A Modification of the Kleinert Splint for Mobilisation of Digital Flexor Tendons

A modification of the Kleinert dynamic splint is described, whereby the rubber band is looped around the hand, rather than attached to the volar aspect of the wrist or forearm. This alters the direction of traction so that the interphalangeal joints are more effectively mobilised.

Some Observations on Controlled Mobilisation Following Flexor Tendon Injury

Several modifications of the Kleinert splint are described including a modified pulley bar, taping of the pulps to prevent skin ulceration and the use of constant-tension springs to simulate more closely the normal flexor muscle function.
