Destructive hip disease complicating traumatic paraplegia.

Recent progress in the management of spinal cord injury has provided longer survivals, and as a result the incidence of secondary bone and joint disorders has increased. Joint lesions due to syringomyelia complicating a cervical spinal cord injury are the most common of these disorders. We report a case of destructive hip disease 7 years after an injury responsible for complete paraplegia with sensory loss. The joint lesions were painless, and there was no local evidence of inflammation. Hip radiographs disclosed atrophic osteoarthropathy with complete destruction of the femoral neck and head. This unusual case raises questions about the pathophysiology of neuropathic osteoarthropathy in paraplegics.
