Ligamentous stabilization of the distal radioulnar joint

Tech Hand Up Extrem Surg. 2004 Dec;8(4):239-46. doi: 10.1097/00130911-200412000-00007.


Instability of the distal radioulnar joint results from fracture and/or malunions of the forearm bones, disruption, or laxity of the ligaments of the triangular fibrocartilage. Such instability often-times is not diagnosed acutely and presents as a chronic problem. When these ligaments fail to heal adequately after injury, distal radioulnar joint instability develops into mechanical problems resulting in pain, limited range of motion, and decreased grip strength. In this case, reconstruction of the disrupted distal radioulnar joint ligaments is essential to restore proper function. In this presentation, a technique of ligament reconstruction using palmaris longus, plantaris, or toe extensor tendon graft is outlined with mid-term functional results.
