We evaluated 45 cases of post-traumatic contractures, 42 PIP and 3 MP joints, treated by the dynamic skeletal traction apparatus (Nakashima external fixator). This apparatus offers the advantage of stretching shortened collateral ligaments and articular capsule by traction, and of mobilizing the stiff joint during active ROM exercise. All the cases showed improvement of ROM. The average total active ROM increased from 31.6° to 65.8°. Only 3 patients had motion pain after the treatment among 23 patients who complained of pre-operative motion pain. It is suggested that this apparatus is very useful for the treatment of the post-traumatic contracture as well as intra-articular fracture.
