[Treatment of carpal fractures. Recommendations of the Hand Surgery Group of the German Trauma Society].

The primary goal in the treatment of carpal fractures is the preservation of a painless wrist function. Scaphoid fractures are the most common carpal fractures and when such a fracture is clinically suspected CT or MRI scans are usually advisable. Only stable and non-displaced scaphoid fractures can be treated conservatively, all other fractures require internal fixation with restoration of normal anatomy. Second most common are fractures of the triquetrum which can occur as chip avulsions of the dorsal rim and are usually treated symptomatically. Fractures of the body of the triquetrum should be treated according to the degree of instability and displacement. This is virtually true for all carpal bones. Perilunate fracture dislocations of the carpus deserve special attention. In these severe injuries a fracture line can run through all carpal bones but the scaphoid is mostly affected. Accurate reduction and internal fixation by screws and K-wires are indicated not only in these cases, but also in carpometacarpal fracture dislocations.
