Johnson-R-K. Stanford University, California. Clin-Orthop [m. 1992 Feb. (275). P 130-2. Surgical and nonsurgical treatment of distal radioulnar joint instability has characteristically been unsatisfactory. This present paper presents a surgical method involving the removal and transfer of the origin of the pronator quadratus to a more dorsal position, which effectively gives a dynamic stabilization to the joint. Temporary internal immobilization is performed with a transverse Kirschner wire that is removed at four weeks, and graded physical therapy is started at that time. Author-abstract.
