title: Tibiofibular synostosis: an unusual cause of shin splint-like pain.
abstract: Tibiofibular synostosis may be an underlying cause of tibial pain with activity or ankle pain of uncertain origin. The diagnosis may be suspected when symptoms begin and progress months after an injury, when symptoms occur with vigorous activity, and when symptoms are most pronounced during midstance and preswing phases of the gait cycle. Confirmation of the diagnosis is easily made through radiographic examination, which should include the entire leg. Bone scan may show increased tracer uptake. Interference with normal dynamic function of the fibula subjects the synostosis to repetitive stress and ultimate fatigue fracture with resultant pain. Conservative treatment is recommended initially. Surgical excision should be reserved for the athletically active patient whose symptoms are gradually progressing and disabling, and whose synostosis has taken on the appearance of mature cortical bone on radiographs. The principles of tumor biopsy should be adhered to, lest the diagnosis be in error. Finally, meticulous hemostasis and use of bone wax may lessen the possibility of recurrence.
