Reversed anatomic distal femur locking plate for periprosthetic hip fracture fixation.

The incidence of femoral fracture on hip prosthesis is increasing. Plate fixation is the method of choice when the prosthesis is stable. In fracture with proximal extension, the quality of the bone fixation is critical and, despite the development of anatomic plates, may be endangered when there are too few proximal screws. To resolve this issue, we recommend using a reversed LCP™ anatomic distal femoral Less Invasive Stabilization System (LISS™) locking plate: e.g., a left distal femoral plate for femoral fracture on right-hip implant. This presents several advantages: minimally invasive surgery, the introduction of the plate being facilitated by the LISS™ ancillary; ease of locking, also thanks to the ancillary; and, above all, multiple proximal trochanteric fixation thanks to the form of this anatomic distal LISS™ plate, improving proximal bone fixation. The present technical note seeks to illustrate the interest of using a "reversed" plate, in terms of simplicity of fitting and quality of reduction and consolidation, while also specifying the associated limitations and tolerance.
