Anatomical Study Of Bone Tunnel Preparation Of Wrist Triangular Fibrocartilage Complex Injury Of ID-based Treatment By Arthroscopic

Objective:Through the bone tunnel preparation of the wrist triangular fibrocartilage complex (TFCC) injury of ID-type treatment by arthroscopic, exploration and discussion of the distal radius, in order to find the tunnel's exit point of distal radius, the choice of surgical procedures provide an anatomical basis for the provision of clinical.Method:In this thesis, including literature and anatomy of two parts, the first part of the research literature:systematic review of the triangular fibrocartilage complex injury pathogenesis, anatomy, classification, treatment methods, research, analysis and treatment factors affecting the healing outlook, and Chinese medicine on the triangular fibrocartilage complex understanding of, then a brief introduction of the knowledge of wrist arthroscopy. Anatomy of the second part:First of all,5 frozen over from the broken wrist corrosion specimens, carefully observe the blood vessels, tendons, nerves and bones of the position relationship, and then distal sigmoid notch sagittal thickness of the foreign 1/3 of the needle points, respectively, distal Kirschner wire into the bone tunnel, and then measuring the angle of Kirschner wire and the distal radius articular surface and the distance data were processed and analyzed.Result:Preparation of the bone tunnels to explore three kinds of programs:the first one: approach:6R; export:the radial of the radial artery←→the ulnar of the brachioradialis tendon (limited to the radial styloid process), the radial of the brachioradialis tendon←→the ulnar of the superficial branch of radial nerve and pollicis development, pollicis brevis tendon; second:approach:6U; export:1-2 solution:the ulnar of the superficial radial nerve and the thumb's show, short thumb extensor tendon←→the radial side of the wrist ulnar length short radial extensor tendon; third:approach:palm ulnar approach; exports:the middle part of the dorsal distal radius, Lister tubercle proximal:the radial of the extensor tendon and pollicis longus tendon←→the ulnar of the long and short radial extensor tendon.Conclusion:Through the anatomy of the distal radial by position and observation, TFCC injury of ID type of three of the prepared bone tunnel feasible approach to complete the distal sigmoid notch of the needle point of orientation, export relatively safe and can meet the wrist Mirror complete TFCC avulsion of the distal radius Department fixed, to realize minimally invasive treatment of carpal joint disease, will become TFCC injury of ID type after clinical surgical treatment of choice for one of the ways.
