ABSTRACT

Diagnosis: Heterotopic ossification

History: 29 year old active duty USMC male who sustained an improvised explosive device (IED) blast to bilateral lower extremities and who eventually required a through-knee-amputation in March 2005. In January 2006 patient was seen in the orthopedic clinic with complaints of pain in left amputation site with prosthesis use. Patient denied fevers, chills, night sweats, or weight loss.

Findings: Preoperative anteroposterior and lateral radiographs of left knee shows through-knee-amputation with irregularly bordered heterogeneous ossified densities juxtaposed to the posteromedial aspect of the distal femur. These ossifications extend through the soft tissues and are consistent with heterotopic ossification. The left femur shows normal bone density. The remainder of the soft tissues appear normal. Postoperative anterioposterior and lateral radiographs of left knee shows through-knee-amputation with small residual focal ossified densities near the medial epicondyle and the medial condyle. The posterior aspect of the distal femur also shows focal area of ossified densities. A percutaneous drain is in place in the soft tissue distal to the medial condyle. Postoperative air is seen in the soft tissues.

Ddx: The history of trauma combined with the clinical course and radiographic findings of the ossifications in the soft tissue are characteristic of heterotopic officiation.

Exam: On physical exam, a hard mass was palpable on the medial aspect of the left amputation site.
