W. Doherty et Jl. Lovallo, SCAPHOLUNATE ADVANCED COLLAPSE PATTERN OF ARTHRITIS IN CALCIUM PYROPHOSPHATE DEPOSITION DISEASE OF THE WRIST, The Journal of hand surgery, 18A(6), 1993, pp. 1095-1098
Chondrocalcinosis is a well-described radiographic finding in patients
with calcium pyrophosphate dihydrate deposition disease of the wrist
and other joints. The medical records and x-ray films of 12 patients e
valuated over an 18-month period for chondrocalcinosis of the wrist we
re examined for symptoms and physical and x-ray film findings. Thirtee
n wrists were affected. All wrists were noted to have calcification of
the triangular fibrocartilage complex. Twelve of 13 wrists had the ch
aracteristic features of the scapholunate advanced collapse pattern of
arthritis. In addition, there was a correlation in our series between
chondrocalcinosis and carpal tunnel syndrome. Destruction of the inte
rosseous soft tissues caused by crystalline deposition could alter the
biomechanics of the wrist in a similar fashion to that of the posttra
umatic scapholunate advanced collapse wrist leading to arthritic sympt
oms.
