Which nonoperative treatment is used for claw deformity?

Claw deformity from intrinsic muscle weakness is best managed nonoperatively by using an anticlaw splint. The splint positions the metacarpophalangeal joints in flexion, which prevents the MCPs from hyperextending. By keeping the MCP joints flexed, the balance between the extensor mechanism and the paralyzed intrinsics is improved, allowing the IP joints to extend more normally and reducing the clawing posture. This nonoperative approach directly addresses the biomechanical issue of clawing without requiring surgery. A dorsal blocking splint is used mainly after flexor tendon injuries to guide and protect tendon healing, not specifically to treat claw deformity. Wrist fusion and nerve graft are surgical interventions, not nonoperative treatments.
