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.
桡尺远侧关节不稳定是由前臂骨骨折和/或畸形愈合、三角纤维软骨韧带断裂或松弛引起的。这种不稳定通常不能被急性诊断出来，而是表现为一个慢性问题。当这些韧带在受伤后未能充分愈合时，桡尺远侧关节不稳定会发展为机械性问题，导致疼痛、活动范围受限和握力下降。在这种情况下，重建断裂的桡尺远侧关节韧带对于恢复正常功能至关重要。在本报告中，概述了一种使用掌长肌、跖肌或趾伸肌腱移植进行韧带重建的技术及中期功能结果。
