Efficacy of Surgical Joint Denervation in Painful Digital Osteoarthritis

Recruiting now · Not applicable

Conditions studied: Osteoarthritis Hand

In brief

Digital osteoarthritis is the second localization of symptomatic osteoarthritis, after the knee. Its cardinal symptoms are particularly intense pain and functional impairment in the case of the erosive form. There is currently no etiological treatment for osteoarthritis. Symptomatic treatments have a modest efficacy, which justifies the search for new treatments. The surgical options are arthrodesis or prosthesis, invasive techniques potentially sources of complications, and finally proposed infrequently given the prevalence of digital osteoarthritis. DECAD is a prospective phase II trial aimed at evaluating the efficacy of surgical joint denervation in painful digital osteoarthritis.
