Heterotopic ossification and rhabdomyolysis

Abstract

Heterotopic ossification and rhabdomyolysis are well described entities but, as far as we know, their association has never been described in the literature. We recently treated a patient who presented with this association. After a suicide attempt, this patient developed rhabdomyolysis of the left upper and lower limbs with peripheral neurological impairment. Two months later radiographs showed ectopic ossification around the left hip. Rhabdomyolysis is underdiagnosed, and is due to local disturbance of the calcium-phosphorus metabolism resulting in soft tissue calcifications. Underlying rhabdomyolysis may be a possible aetiology of heterotopic ossification. Recognition of this may help us to understand the pathophysiology and to improve the management of heterotopic ossification. © 1995, International Spinal Cord Society. All rights reserved.
