Flexor pulley reconstruction using allograft tendon for failed trigger finger surgery: A case report
摘要
Flexor pulley injury can occur after aggressive trigger finger release and may cause flexor tendon bowstringing. For patients suffering from multiple pulley injuries or failed conservative treatment, flexor pulley reconstruction surgery is sometimes required. There are various ways to reconstruct the flexor pulley, and the most commonly used materials are autograft tendons. However, to our knowledge, few studies have described flexor pulley reconstruction using allograft tendons. Herein, we report the case of a 50-year-old female breakfast-store worker who was suffering from left ring finger triggering for years. She underwent several instances of local steroid injection and trigger finger release. During the last trigger finger release, sustained left ring finger pain and bowstringing occurred. Complete A1 pulley injury plus partial A2 pulley tear was noted during the operation. A1 pulley reconstruction was carried out using an allograft tendon. The patient had an uneventful postoperative course and experienced a substantial improvement of her left ring finger pain and function. In conclusion, solitary A1 pulley reconstruction using an allograft tendon with a non-encircling non-bone-anchoring method provides sufficient stability and satisfactory functional outcomes for bowstringing originating from complete A1 pulley injury plus A2 pulley partial tear.
