For patients with intertrochanteric fractures, long-stem prostheses (cemented or uncemented depending on bone density and morphology of medullary cavity) were used if it was noted during the surgery that calcar femorale or lesser trochanter fracture was present, and that medial femur could not support the prosthesis sufficiently (Fig.1).
