Key result
Subtrochanteric femur fracture links to rare superficial femoral artery injury, potentially enhanced by preexisting calcification.
Why the study?
Superficial femoral artery injury from femoral fracture bone fragments is rare, often overlooked, and may be enhanced by preexisting arterial wall calcification.
Case Report (n=1)
Highlights the rare occurrence of superficial femoral artery injury following subtrochanteric femur fracture, particularly in the presence of preexisting arterial calcification.

Clinicians should consider delayed SFA injury after femoral fracture; case report extends recognition of rare events but leaves open calcification's role.
Superficial femoral artery injury due to bone fragment of femoral fracture is often overlooked as it occurs only in rare cases of femoral fractures and the onset of symptoms usually happen weeks or even months later. The deep femoral artery, in fact, is more susceptible to injuries associated with femoral fractures. Moreover, a preexisting calcification lesion of the arterial wall might enhance the chance of such arterial injury, a condition that we noticed in the case we are reporting. We will illustrate a rare case of calcified superficial femoral artery injury complicating subtrochanteric femur fracture.

Tarhuni et al. (2024) conducted a case report in Superficial femoral artery pseudoaneurysm post-subtrochanteric femur fracture (n=1). Subtrochanteric femur fracture was evaluated. A subtrochanteric femur fracture was complicated by a rare superficial femoral artery injury, potentially enhanced by a preexisting calcification lesion of the arterial wall.
