The Application of Hyaluronic Acid/Alginate Sheet to Flexor Pollicis Longus Tendon Repair to Prevent Adhesion Formation: A Second Look

Abstract

Soft tissue traumas with tendon lacerations are challenging injuries to manage. Repair of these tendon injuries can be complicated by adhesions postoperatively, limiting patient function and satisfaction. Biologic agents have been developed to optimize tendon gliding after repair and can be used as adjuncts. When used in conjunction with a postoperative rehabilitation protocol, they can help restore function and range of motion (ROM). It is rare that the orthopedic surgeon can visualize a healed tendon repair as the results are often followed clinically. We present the case of a patient who underwent flexor tendon repair with the addition of hyaluronic acid (HA) and alginate tendon wrap. This same patient sustained a distal radius fracture one year later, allowing for a second look at the flexor tendon repair site during the operative fixation of his fracture.
