[Semilunar dislocations. A report of 8 cases. (Orthopedic service-University Hospital Center of Treichville-Abidjan)].

The authors have underlined in a study made on 8 observations that the lunate dislocation is scar. All their patients were men under 40 years old. Industrial injury was the most dominant cause. Using WITVOET and ALLIEU's classification, they noticed a predominance of perilunar and posterior dislocations (7/8 cases). Perilunar anterior dislocations and isolated scaphoid carpal dislocation have not been encountered. The treatment which has been orthopaedic or surgical has given moderate results: Good results = 4; Average result = 1; Bad results = 2; Non seen to again = 1 The authors think that a precocious diagnosis and an orthopaedic treatment in the forms detected early and surgical treatment in ancient forms are the only guarantee of a good functional result avoiding dread diseases such as carpal instability, radiocarpal arthrosis.
