Long-term radial extracorporeal shock wave therapy for neurogenic heterotopic ossification after spinal cord injury: A case report

Context: Heterotopic ossification is characterized by abnormal growth of bone in soft tissues. Neurogenic heterotopic ossification is also closely related to central nervous system injuries and has been reported to respond to radial extracorporeal shock wave therapy. Findings: In this case, a radial extracorporeal shock wave therapy (five times per week, lasted for almost one year) was applied to a patient with neurogenic heterotopic ossification on the left hip as a result of spinal cord injury. Throughout the treatment session, the heterotopic ossification lesion was gradually diminished, associated with the increase in joint range of motion, pain mitigation and decrease in serum alkaline phosphatase level.
