Spiral oblique retinacular ligament (SORL) mallet correction in a finger with a proximal interphalangeal joint transferred from a toe.

The use of a spiral oblique retinacular ligament (SORL) reconstruction is reported in a middle finger that had previously undergone reconstruction of the proximal interphalangeal (PIP) joint, using a free, vascularized, second-toe PIP joint transfer. The SORL procedure was applied for the reconstruction of the terminal tendon. A satisfactory postoperative range of joint mobility and stability was achieved.
