Abstract
Aim of the work
The aim of this work is to study the principles, indications, operative technique and the outcome of the commonly performed limited wrist arthrodeses.
The wrist joint is a biaxial ellipsoid joint. It is formed by the articulation of the radius with the scaphoid and the lunate. The lunate and triquetrium also articulate with the cartilaginous disc not the ulna. The cartilaginous disc creates a close relationship between the ulna and the carpal bones and binds the distal ends of the radius and the ulna together. The carpal bones are eight bones arranged iti proximal and distal rows. The proximal row consists of the scaphoid, lunate, triquetrum and pisiform. As there are no muscular attachments to the proximal carpal row, it has been described as an intercalated segment by lambrinuidi in 1934. The distal carpal row consists of the trapezium, trapezoid, capitate and the hamate. The distal row is controlled by the extrinsic flexor and extensor tendons, and the proximal segment’s motion, therefore, induced by the distal carpal segment. The ligaments of the wrist are classified into extrinsic and intrinsic ligaments.
