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
