Trigger finger treatment by ulnar superficialis slip resection (U.S.S.R.).

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.

Heterotopic ossification of the elbow in patients with burns. Results after early excision.

Heterotopic ossification which may develop around the elbow in patients with burns may lead to severe functional impairment. We describe the outcome of early excision of such heterotopic ossification in 28 patients (35 elbows), undertaken as soon as the patient's general and local condition allowed. The mean age at operation was 42 years. The mean area of burnt body surface was 49%. The mean pre-operative range of movement was 22 degrees in flexion/extension and 94 degrees in pronation/supination. The mean time between the burn and operation was 12 months with the median being 9.5. The mean follow-up period was for 21 months. At the last review, the mean range of movement was 123 degrees in flexion/extension and 160 degrees in pronation/supination. Clinical evidence of recurrence was seen in four patients, occurring within the first two months after operation. Nevertheless, three of these elbows gained 60 degrees or more in flexion/extension and in pronation/supination. Based on this experience, we recommend early surgical treatment of heterotopic ossification of the elbow in patients with severe burns.
