Innovative Botulinum Toxin Injection: A Promising Nonsurgical Solution for Carpometacarpal Osteoarthritis.

Abstract: Carpometacarpal joint (CMCJ) osteoarthritis (OA) is a common condition that can cause significant pain and functional limitations. Although mild-to-moderate CMCJ OA symptoms can be managed with conservative measures, effective nonsurgical options for patients with moderate-to-severe OA unresponsive to conservative measures are limited. This case report introduces a novel approach involving intra-articular incobotulinumtoxinA (BoNTA) injection for CMCJ OA, resulting in significant and prolonged pain relief and enhanced functionality. This groundbreaking intervention effectively bridges the gap between nonsurgical and surgical treatments, offering a promising alternative for individuals with CMCJ OA.
