Percutaneous Injection of Calcium Phosphate Bone Substitute into a Chronic Calcaneal Bone Marrow Lesion Associated with a Fragility/Insufficiency Fracture: A Case Report.

Pathologic fractures and marrow lesions of bones in the human foot and ankle can occur secondary to a variety of risk factors. The calcaneus is a rearfoot bone that provides support during weightbearing activities and walking. Although low-risk stress injuries to the bones in the foot and ankle are predominantly treated conservatively in low-demand patients, there are situations where surgical intervention is warranted. Surgical treatment options for calcaneal bone marrow lesions (BML) secondary to stress fractures are dearth with limited evidence supporting the use of the subchondroplasty (SCP) technique. This case report discusses surgical treatment with SCP of a chronic calcaneal BML sustained secondary to a insufficiency/fragility fracture.
