case_images: The patient was treated with a total elbow arthroplasty and an ulnar nerve anterior subcutaneous transposition (Figure 1).
case_images: (a, b) Marked heterotopic ossification (HO) seen around the prosthesis at the 6-week follow-up X-rays. (c, d) Maturation of the HO seen at 18 weeks postoperation.

case_images: HO development was noticed radiographically at 6 weeks (Figures 2(a) and 2(b)). This patient clinically and radiographically was followed until cortication and maturation of the HO with no change in HO size were noted on consecutive radiographs 6 weeks apart (Figures 2(c) and 2(d)).
case_images: Select computer tomographic views of the elbow in the sagittal (a), coronal (b), and axial (c) planes demonstrating significant HO (marked by the asterisk) engulfing the hardware and native bone.

case_images: CT imaging was then performed to plan for operative excision of the ectopic bone (Figure 3).

case_images: An open excision of HO and soft tissue releases (Figure 4) was conducted.

case_images: Her wound was well-healed, and there was no significant recurrence of the HO on follow-up radiography (Figure 5).
