Stener-Like Lesions in the Metacarpophalangeal Joint of the Fingers / 대한정형외과학회잡지

Three Stener-like lesions of the metacarpophalangeal joint of the fingers and a rupture of the first dorsal interosseous muscle mimicking the lesion in the index finger were observed. Two cases in the little fingers had a true Stener's lesion. In one case in the index finger, the ruptured ligament was retracted and located under the intact sagittal band, which was also observed by preoperative magnetic resonance imaging (MRI). Rupture of the first dorsal interosseous muscle was misdiagnosed preoperatively as a Stener's lesion in the index finger by ultrasonography. MRI should be an essential differential diagnostic exam for collateral ligament ruptures of the metacarpophalangeal joint of the fingers.

Spontaneous Rupture of the Extensor Carpi Radialis Brevis and Radial Collateral Ligament of the Elbow in a Recreational Golfer: Surgical Experience of Repair of a Chronic Retracted Tendon and Ligament

Lateral epicondylitis with rupture of the radial collateral ligament of the elbow has not been reported in the literature. We report on a case of a recreational golfer who had not received steroid injection and had no trauma history. The patient was treated with open surgical repair. At 2 years follow-up, satisfactory clinical and radiological outcomes were observed with return to pre-injury level. The authors report this case and review the literature.

An Isolated Complete Rupture of Radial Collateral Ligament of the Fifth Metacarpophalangeal Joint: A Case Report

PURPOSE: Rupture of a collateral ligament of the metacarpophalangeal joint is rare except in the thumb. The injured digit became flexed and deviated toward ulna side by the hypothenar intrinsic musculature. Incomplete rupture of a collateral ligament of the metacarpophalangeal joint can be often managed by splinting the affected digit in flexion position, however, in the case of complete tears that distraction of the ends of the ruptured collateral ligament is too great to allow repositioning by splinting. Primary repair of the ruptured collateral ligament or reattachment to bone by a pull-out wire, or tendon graft technique appears to be adequate. METHODS: We report a case of instability of fifth metacarpophalangeal joint due to complete rupture of radial collateral ligament. This 18-year-old male presented pain in his right outstretched hand after trauma. The diagnosis was obtained by physical examination and simple radiography. Because of persistent instability after the initial conservative treatment, open reduction and repair surgical treatment was required. RESULTS: The fifth metacarpophalangeal joint became free of pain and stable under forced lateral deviation. Postoperative results showed good metacarpophalangeal joint function and stability during 8 months follow-up period. CONCLUSION: Because of the interposition of the sagittal band between the ruptured ends of radial collateral ligament such as Stener-like lesion of the thumb, surgical repair of metacarpophalangeal joint collateral ligament of the finger was justified in case of complete laxity in full flexion.
