Femoral nail impingement with the quadriceps: an ultrasound case report on orthopedic hardware conflict.

Femoral shaft fractures are commonly treated with intramedullary nailing; however, this procedure can lead to complications. This study explores the role of ultrasound in diagnosing femoral hardware impingement. We present the findings in two patients with persistent thigh pain after femoral intramedullary nailing. Ultrasound successfully identified hardware impingement. Removal of the offending screw led to symptom resolution, with a follow-up US confirming the absence of residual conflicts.
