Ultrasound diagnosis of profunda femoris pseudo-aneurysm following nail-plate fixation of a transcervical femoral fracture.

False aneurysms of the profunda femoris artery as a complication of orthopaedic operative procedures have been well documented in the past. They have occurred after osteotomy of the proximal femur (Basset & Houck, 1964; Meyer & Slager, 1964; Dumanian & Kelikian, 1969; Mackenzie et al, 1983), intramedullary nailing of the femoral shaft (Dickson, 1968) and nail and plate operations for neck of femur fractures (Dameron, 1964; Fordyce, 1968; Wolfgang et al, 1974). Although usually pulsatile, several examples of nonpulsatile aneurysms have been reported (Mikulin & Walker, 1984; Read, 1984). Ultrasound is routinely used in the diagnosis of aortic aneurysms and, more recently, in the management of peripheral aneurysms (Davis et al, 1977; Gooding & Effeney, 1980). In the case we describe, ultrasound revealed a false aneurysm of the profunda femoris demonstrating its size and site, where clinical examination was inconclusive. An 85-year-old woman fell at home, sustaining a Garden Stage II transcervical fracture of...
