Injury of a Branch of the Arteria Profunda Femoris after a Pertrochanteric Femur Fracture

Abstract

An 85-year-old patient suffered a pertrochanteric fracture of his left femur caused by a fall. He underwent osteosynthesis with a DYAX-nail on the day the accident took place. During his recovery an increasing dislocation of the lesser trochanter caused a violation of a branch of the arteria profunda femoris that required surgical intervention. The arterial lesion was treated by embolisation successfully. An arterial lesion due to a per- or subtrochanteric trauma that needs surgical intervention is extremely rare, iatrogenic arterial violations are described in up to 1 % during the transfemoral drilling procedure in order to fix common plate systems on the proximal femur. This case report establishes for the first time a bleeding complication caused by secondary dislocation of the lesser trochanter. In case of a per- to subtrochanteric fracture the biomechanical advantages of an intramedullary stabilisation add to the avoidance of transfemoral drilling in comparison to an extramedullary plate system fixed on the femoral shaft.

Key words
