Abstract:
A case of chronic subluxation of the digital extensor tendon is reported, and a new surgical technique for repair is described. A partial-thickness trapdoor three-sided flap is made out of the dorsal joint capsule, brought through an incision in the ulnar sagittal band, and sutured back down. This centers the tendon and creates a new, stable tunnel through which it may glide.
