Heterotopic ossifications in midline abdominal scars: a critical review of the literature.
2010
Heterotopic ossification (HO) is the formation of bone outside the skeletal system, including old incisions. Although a well-known complication after orthopaedic surgery, it is still considered an uncommon phenomenon after vascular surgery. Recent data, however, show that up to 25% of all patients develop HO after midline abdominal surgery. In this article, we present the case of a symptomatic HO, 7 years after an aortobiiliac prosthetic reconstruction for an abdominal aortic aneurysm. Furthermore, we review current insights into the aetiology and show bone morphogenetic proteins to play a crucial role. Treatment options are also reviewed, but lacking any supportive evidence for other therapies, surgical excision with primary closure is the treatment of choice.
