Abstract
Cases are reported of two men who sustained bilateral hip injuries while undergoing convulsive therapy and of one woman who sustained bilateral hip injuries during a uraemic convulsion. A further twenty-three previously unreported cases are analysed, sixteen of which were of simultaneous bilateral femoral neck fractures and five of which were simultaneous bilateral central dislocations of the hip. One other patient sustained his injuries in an epileptic fit. A review of the literature has revealed another thirty-five cases of bilateral hip injuries, most of them caused by convulsive therapy, but a few by accident, disease of the femoral neck, or epilepsy.
One case is included of a rare double injury, a femoral neck fracture on one side and a central dislocation on the other. I have found no previous reference to this combined injury.
Double hip injuries are very rare in relation to the large numbers of patients receiving convulsion therapy, but the change from pharmacological to electrical methods has not prevented their occurrence and at least fifteen are known to have occurred during the last six years.
A wide age range is represented, and many fractures of convulsive origin have occurred in fit, well nourished, adult men. Only a few have been found in more elderly and possibly osteoporotic patients.
All the "convulsive " injuries were sustained during unmodified treatment, and mention is made of the differences of opinion among psychiatrists about the use of anaesthesia and of relaxant drugs in convulsion therapy.
These are the most severe injuries complicating convulsion therapy, and the most difficult for the orthopaedic surgeon to treat.
