[False aneurysm of the deep femoral artery due to pertrochanteric fracture of the hip with displaced fragment of the lesser trochanter].

We report the case of an 82-year-old man with a pertrochanteric fracture of the hip and an avulsion of the lesser trochanter. During the third postoperative week after unproblematic correction with a gamma nail, a swelling of the proximal thigh occurred. Angiographs showed a false aneurysm of the deep femoral artery which was treated by suture.
