[Injury of the collateral ligaments of the metacarpophalangeal joint of the thumb and therapy].

The authors report on their experience on 176 patients with lesions of the ulnar collateral ligaments. Two samples were compared: the fresh rupture and immediate suture, and the old lesion treated by a special plasty with palmaris tendon (Bäuerle/Reill). The long term results (at least 2 years) of both collectives were nearly identical. The authors recommend immediate repair.
