[Isolated luxation of the proximal tibio-fibular joint as a rare sports injury].

The authors present three cases of the rare isolated luxation of the fibular head. Anatomy, injuring mechanism and classification are described. The diagnosis is established by clinical examination and comparative X-ray radiography. If a luxation is irresponsible under general anesthesia (two of our cases), open reposition has to be performed with subsequent temporary nail or screw fixation. A postoperative immobilization with plaster cast on the thigh over a period of six months is necessary. After removal of the plaster cast, the material must immediately be removed in order to avoid complications such as fatigue fractures of the material. If this therapy scheme is observed, surgical treatment can be performed without problems and good functional therapy results will be achieved.
