Heterotopic ossification in the residual lower limb in an adult nontraumatic
amputee patient.Heterotopic ossification usually occurs in association with
various neurologic injuries, trauma, and burns. There have been few reports in
the literature of heterotopic bone formation at the distal residual limb in the
adult amputee population. All previous cases with a documented cause have
involved traumatic amputations. An adult diabetic patient who underwent left
below-the-knee amputation for progressive Charcot foot is presented. The patient
began to experience residual limb pain and decline in functional mobility 4-5 mos
after surgery. Radiographs demonstrated heterotopic bone around the distal tibial
and fibular remnant with extension into adjacent soft tissue. Triple-phase bone
scan testing and tissue biopsy verified active heterotopic ossification. The
patient was treated with etidronate and eventually was able to ambulate with a
prosthesis on a regular basis. This case demonstrates that heterotopic
ossification may occur and be a source of residual limb pain in the adult
nontraumatic amputee population.
