Presentation
Ambulating and patient heard "crack". Pain in right hip. Past history multiple myeloma.
Patient Data
Right subtrochanteric pathological fracture. The fracture is posteriorly displaced and mildly impacted. The proximal fracture fragment is laterally angulated. Surrounding the fracture is a lytic lesion, which had been previously demonstrated as a myelomatous deposit.
Case Discussion
Pathological fracture refers to a fracture through an area of underlying abnormal bone. Although in the vast majority of cases this is a underlying malignant lesion, such as a metastasis or myelomatous deposit, this need not always be the case.
Pathological fractures are a common complication of multiple myeloma.
