Metacarpal ligament sling tenodesis.

For patients with intrinsic paralysis, if a tendon transfer is not possible, a metacarpal ligament sling tenodesis can effectively correct the claw deformity and synchronize metacarpophalangeal and interphalangeal joint flexion and extension. This sling tenodesis consists of a tendon graft looped about the deep transverse metacarpal ligament and sutured to the lateral bands of adjacent fingers.
