Open release of the Al pulley is a widely known procedure for the treatment of trigger finger. However, a subset of patients present trigger finger with a positional contracture of the proximal interphalangeal joint. These patients usually have a long history of trigger finger or have already undergone one surgery to treat trigger finger. In both instances, surgical intervention with only transection of the Al pulley is ineffective. In this study, 36 patients (39 fingers) were treated by resection of the flexor digitorum superficialis after section of the Al pulley (mean age: 63 y). We performed a retrospective review with a mean follow up of 30 months. The mean pre-operative extension deficit of the proximal interphalangeal articulation was 24 degrees, and 28 of the 39 affected fingers achieved filli extension following the surgical intervention. All of the resected tendons had histological damage. This technique is a useful treatment for selected patients whose trigger finger is associated with a positional contracture.
