Ligament reconstruction of the distal interosseous membrane to treat distal radioulnar joint instability: Case series of four patients.

We describe a new ligament reconstruction of the distal interosseous membrane to treat chronic distal radioulnar joint instability without osteoarthritis and report the results of a series of four cases. This ligamentoplasty appears to be a technically simple and effective joint stabilization procedure to contend posterior-anterior ulnar head instability. LEVEL OF EVIDENCE: IV.
