Arthroscopic Wrist Anatomy

摘要

Wrist arthroscopy allows excellent visualization of the articular surface of the carpal bones,and ligaments that is not possible via an open arthrotomy 1. Arthroscopy of the wrist is now a primary method of evaluating and treating many intra-articular wrist conditions including triangular fibrocartilage complex tears, chondral injuries, distal radius fractures, carpal fractures, wrist ligament injuries, loose bodies, and ganglions (Table 2.1) 2. A thorough knowledge of overall wrist anatomy including topographic landmarks, extracapsular tendon and neurovascular structures, and intracapsular ligamentous and osseus structures is essential to proper diagnosis and treatment 3. Chapter 1 outlined the basic setup and surface topography of the wrist joint, as well as the creation of the standard radio-carpal and mid-carpal portals. This chapter will focus on the internal anatomy of the radio-carpal, mid-carpal, distal radio-ulnar joint, and thumb carpometacarpal joint.
