不同类型的三角纤维软骨复合体(triangular fibrocartilage complex,TFCC)损伤,均可引起腕尺侧疼痛、活动受限,甚至桡尺远侧关节(DRUJ)不稳定等。TFCC因中心(占80%)区域无血管,自身修复困难,传统的手术治疗虽能缓解症状,近期疗效好,但均破坏了TFCC稳定及DRUJ的功能。远期疗效差。随着显微外科的发展,应用带血管蒂的骨膜瓣移位术修复关节软骨缺损的报道不断增多。临床上也取得了可喜的效果。我们在解剖观测腕关节周围血供的基 Different types of triangular fibrocartilage complex (TFCC) damage can cause ulnar pain, limited mobility, or even distal radioulnar joint (DRUJ) instability. TFCC has no blood vessels in the center (80%) area, so it is difficult to repair itself. Traditional surgical treatment can relieve the symptoms and has good curative effect in the near future, but all of them destroy the stability of TFCC and the function of DRUJ. Poor long-term efficacy. With the development of microsurgery, the application of the pedicled periosteal flap pedicled with periosteal flap to repair articular cartilage defects has been reported. Clinically also made gratifying results. We dissect the base of the blood supply around the wrist
