False about Charcot’s joint in diabetes mellitus is (AIIMS Nov 2012)
|A||Limitation of movements with bracing|
|C||Total ankle replacement|
Total ankle replacement
a. Charcot’s joint refers to neuropathic osteoarthropathy in which there is progressive degeneration of a weight-bearing joint, a process marked by bony destruction, bone resorption, and eventual deformity.
b. Any condition resulting in decreased peripheral sensation, proprioception, and fine motor control can cause Charcot’s joint. Common causes of such osteoarthropathy are:
i. Diabetes mellitus neuropathy (M.C.)
ii. Alcoholic neuropathy
iii. Cerebral palsy
v. Syphilis (tabes dorsalis)
vi. Spinal cord injury
Treatment of Charcot’s arthropathy is focused on limitation of activity and appropriate bracing or casting. A Charcot’s joint is usually a contraindication for total joint arthroplasty.
