Intravesical Migration of a Screw during Hip Osteosynthesis: A Case Report

The incidence of fractures of the upper extremity of the femur continues to increase as the population ages. Dynamic hip screw (DHS) is the treatment of choice for stable fractures. We report the case of an 80-year-old man with no notable pathological history presenting with a pertrochanteric fracture. Intraoperatively, the cephalic screw migrated unexpectedly into the pelvis. Several attempts were made to remove it, but the screw had penetrated deep into the pelvis, making removal impossible through the femoral neck. An emergency abdominal CT scan was performed showing that the screw had penetrated into the bladder. The urological surgeon was called in to remove the screw via a medial abdominal approach, which was fnally removed without any further complications. Intravesical migration of a DHS screw is a rare complication. Compliance with the DHS surgical technique, especially in very old osteoporotic patients, can avoid this complication.
