Surgical release of the A1 pulley for treatment of trigger finger normally produces excellent results. However, in patients with long-standing disease, there may be a persistent fixed flexion deformity of the proximal interphalangeal joint. This is sometimes due to a degenerative thickening of the flexor tendons and may be treated by resection of the ulnar slip of flexor digitorum superficialis tendon. One hundred seventy-two patients (228 fingers) who had undergone this procedure were reviewed at a mean follow-up of 66 months. Mean pre-operative fixed flexion deformity of the proximal interphalangeal joint was 33 degrees. All but eight fingers were improved by surgery and there was an average gain of 26 degrees in passive extension (7 degrees residual fixed flexion deformity) of the proximal interphalangeal joint. Full extension was attained in 141 of the 228 fingers, and in all 101 fingers with a pre-operative loss of passive extension of 30 degrees or less. This technique is indicated for patients with loss passive extension in the proximal interphalangeal joint and a long history of triggering.

Systemic lupus erythematosus associated ocular manifestations usually consist of cotton-wool spots and retinal hemorrhages. The authors report one case of lupus choroidopathy revealed by bilateral serous retinal detachment, occurring 4 months after a systemic flare-up of the disease. An immune complexes-mediated phenomenon is involved in these manifestations, which are usually controlled by systemic corticosteroids and immunosuppressive agents. Plasma exchanges were successfully applied in this case, resulting in a disappearance of the retinal detachment in one month.

Postero-lateral instability of the elbow joint is a rare clinical condition, commonly related to a disruption of the lateral collateral ligament complex of the elbow. Twenty elbow joint specimens were studied in order to describe the morphologic characteristics of this complex, and to determine the role of its different components in the stability of the elbow. After a morphologic and morphometric investigation, serial divisions of the medial bundle of the lateral collateral ligament were performed, with or without section of the annular ligament and the anterior bundle of the lateral collateral ligament. The anterior and medial bundles of the lateral collateral ligament had close relationships with the annular ligament and a common proximal course. Isolated section of the medial bundle of the lateral collateral ligament induced only minor laxity of the elbow joint. Combined divisions of the medial and the anterior bundles at their humeral insertion, or the medial bundle and the annular ligament at their ulnar insertion resulted in a reproducible subluxation of the ulno-humeral joint. Thus, postero-lateral rotatory stability of the elbow joint is largely maintained by the lateral collateral ligament complex, composed of three elements: the anterior and medial bundles of the lateral collateral ligament, and the annular ligament. In clinical practice, chronic postero-lateral instability is best treated by a ligamentous reconstruction, that must take into account all these anatomic considerations. We report here a new technique of ligamentoplasty using the fascia of the extensor carpi ulnaris muscle.
