Arthroscopic findings in gout of the wrist.
OBJECTIVE
We have recently treated several patients with gout of the wrist and scapholunate ligament pathology. The purpose of this investigation was to report the arthroscopic findings of 7 such patients.


METHODS
We searched our medical records for patients with a diagnosis of gout and nontraumatic wrist pathology. We retrospectively reviewed the clinical, arthroscopic, radiographic, and pathologic findings in 7 patients who failed nonsurgical management and were treated with wrist arthroscopy.


RESULTS
All 7 wrists had diffuse synovitis and crystalline deposits throughout the radiocarpal joint. There were focal crystalline precipitates on the scapholunate and lunotriquetral ligaments but not on the triangular fibrocartilage complex. Scapholunate or lunotriquetral ligament disruption was noted in 6 and 5 wrists, respectively. An early scapholunate advanced collapse pattern of arthritis was present in 5 patients.


CONCLUSIONS
Gout affecting the wrist may be associated with crystal deposition on the scapholunate and lunotriquetral ligaments. Ligament incompetence and a scapholunate advanced collapse pattern of wrist arthritis was noted in 6 of our 7 patients.
