[Therapy of acute triquetrum fractures and LT ligament injuries].
Fractures of the triquetrum: Triquetrum fractures consist of two types: chip fractures of the dorsum and fractures of the body of the bone. Dorsal cortical fractures respond well to a short time splint or cast support. Non-displaced fractures of the body can be treated by immobilization for four to six weeks. Displacement of body fractures is very rare and often the result of perilunate instability. This condition usually requires open reduction, internal fixation and ligament repair. Lunotriquetral ligament injury: Partial lunotriquetral ligament disruption and dynamic instability should be treated by immobilization alone. Acute complete ligament disruption with static instability results from perilunate instability and requires operative treatment with ligament reconstruction and joint stabilization with K-wires followed by longer immobilization.
