AbstractDuring a taekwondo competition, a 20-year-old female competitor injured her left thumb. There was pain, swelling, and tenderness at the ulnar side of the metacarpophalangeal joint. Plain radiography demonstrated an avulsion fracture with a small-size fragment at the base of the proximal phalanx. A mini hook plate was used to repair the lesion. The patient was satisfied with the results and returned to her sports activities after 2 months.

Operative Findings

Acute ulnar instability of the metacarpophalangeal joint of the thumb is divided into two distinct groups, according to the history, clinical, radiological and operative findings. In the first group it is a soft tissue injury, as a result of an unresisted abduction force to the thumb. In the second group, following a resisted abduction force, there is avulsion of a bony fragment from the base of the proximal phalanx, which is the site of common insertion of both the ulnar collateral ligament and the adductor pollicis. This is confirmed by post-mortem studies.

Subjective Result

70 patients with total avulsion or rupture of the ulnar collateral ligament of the first metacarpophalangeal joint were treated surgically, using an absorbable self-reinforced poly-L-lactide mini-tack placed through the ligament and a channel in the base of the proximal phalanx. The device stabilized the joint immediately, and 69 ligaments remained stable at 6 months. The subjective result was good or satisfactory in 66 of the cases. One case needed further surgery for pain in the scar and another developed local infection 9 months post-operatively. On the basis of these findings, the new absorbable fixation method seems to be a suitable method for clinical use.
