Abstract
A partial or complete rupture of the ulnar collateral ligament of the MPJ of the thumb, skier’s thumb, is an often-encountered problem. It can occur with any fall on an outstretched hand when a thumb that is already in abduction receives an extra valgus stress. The injury occurs commonly as distal avulsion of the ligament from its insertion in the base of the proximal phalanx with or without bony fragment, also rarely occurs as proximal avulsion or mid-substance tear.
Nonsurgical management of incomplete tears usually results in full recovery of thumb MPJ stability and motion. In contrast, complete ruptures often are associated with a Stener lesion and have little potential for regaining stability without surgical intervention. In these cases, acute anatomic repair of the UCL almost uniformly restores strength, stability, and motion to the thumb MPJ. In neglected cases, UCL insufficiency occurs, increasing the likelihood of pain, weakness, and premature degenerative arthritis.
Different surgical techniques can be used. The UCL can be fixed with a suture anchor or with transosseous stitches. Small bone fragments can be removed; larger ones can be fixed with a K- wire or with miniscrew.
The aim of this study is to evaluate the different techniques in the treatment of acute thumb ulnar collateral ligament injury. Twenty patients were included in this study, for all patients preoperative radiographs and US were done. Follow up period was 3 months and the results were evaluated by Mayo wrist score both pre and post-operatively.
In this study three different methods of fixation were used depending on the size of the fragment; mini screw, k-wire, and two hole mini plate pull out suture. The results were comparable between the three groups which reflect the fact that different surgical techniques can be used. Which one applies depends on the anatomy of the lesion and can often only be decided upon during surgery.
