Pronation and supination are often painful or limited due to DRUJ
DRUJ innervation is derived mostly from the anterior interosseous nerve on the ulnar side and by some lesser contributions from the posterior interosseous nerve.
DRUJ injury must be suspected when, on examination, there is a lack of pronation or supination (with or without elbow injury).
The congruency of the DRUJ is maintained by a connection between the distal radius and the distal ulna.
Watanabe and associates (10) examined the contribution of the IOM to DRUJ stability and found that dorsal dislocations of the radius relative to the ulna most likely indicated distal IOM rupture.
Many studies have sequentially sectioned DRUJ soft tissue restraints.
They are often associated with injuries to the ECU subsheath and DRUJ
Surgical techniques for distal radius malunion depend on the type of deformity, DRUJ
dysfunction, and surgeon preference.
Radiographic evaluation of the DRUJ should include a neutral posteroanterior (PA) view and true lateral view of the wrist.
Additionally, he underscored the fact that these procedures do not address instability at the DRUJ and will fail without an intact TFCC.
The Sauve-Kapandji procedure is a combination of creating a pseudarthrosis at the level of the metadyaphysis of the distal ulna with an arthrodesis of the DRUJ while preserving the head of the ulna.
31,33-47) In a study of 15 patients with primary or post-traumatic arthritis of the DRUJ, Minami and coworkers found significant improvement in grip strength to 88% of the contralateral side.
