Abstract:
Operative fixation of distal femur fractures in patients with osteoporotic bone can be challenging. Treatment with either lateral locking plate or retrograde intramedullary nail alone may not provide adequate fixation to allow for early mobilization. Rather, fixation using the nail plate combination (NPC) to treat distal femur fractures in the elderly may offer improved biomechanical stability to achieve immediate weight-bearing, especially in the setting of complex fracture patterns and osteoporosis. Here, we describe the rationale, step-by-step technique, and outcome following 2 cases: 1 patient treated with a true NPC procedure using retrograde intramedullary nail and standard locking plate, as well as a NPC procedure using a novel locking attaching washer plate.
