Synovial Chondromatosis / 대한정형외과학회잡지

Synovial chondromatosis is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue which disintegrates into the joint and continues to grow. Of the eight cases of synovial chondromatosis seen by the authors, three cases involved the knee, two of these were bilateral, three cases involved the elbow, one the hip joint and one the proximal phalanx of the right middle finger. The diagnosis of synovial chondroamtosis was made by histopathological findings of the excised mass. Most synovial chondromatosis cases obtained favorable results by removing masses from the joint and at the same time performing a partial synovectomy, except one case in which degenerative arth ritis had developed proeoperatively.

Treatment of the Buttonhole Deformity of Fingers / 대한정형외과학회잡지

A buttonhole deformity of the finger is characterized by flexion of the pmximal interphalangeal joint and hyperextension of the terminal interphalangeal joint. When the central slip of the extensor tendon and the triangular ligament are ruptured,(or severed) on the base of the middle phalanx, buttonhole deformity will result.This article is based on clinical and follow up studies of 5 patients with buttonholedeformities. Five cases were treated by the modified Littler method and were followed from 4 months to 24 months postoperatively and good results were obtained in all cases.
