BILATERAL CENTRAL ACETABULAR FRACTURE-DISLOCATIONS SECONDARY TO SUSTAINED MYOCLONUS

This case report presents a patient with bilateral central acetabular fracture dislocations secondary to sustained myoclonus treated with de layed bilateral total hip arthroplasty, This is an unusual mechanism o f injury, but is similar to other uncontrolled muscular contractions, such as electroconvulsive therapy and seizures, Because of ongoing myo clonus, the patient initially was treated nonoperatively, The patient then successfully had staged bilateral total hip arthroplasty 15 month s after injury, This case exemplifies that forceful, uncontrolled musc ular contraction can cause bilateral symmetric fracture dislocations. In patients with a history of seizure or myoclonic contracture with su bsequent pain or loss of function, radiographs are indicated and skele tal fracture or joint dislocation must be ruled out. Secondary reconst ruction can be recommended when the patient is medically stable.
