Treatment of intertrochanteric nonunion after sliding hip screw fixation with a short cephalomedullary nail.

Intertrochanteric femur fracture nonunions are a rare complication that can be difficult to treat with limited evidence regarding treatment options. Revision fixation is typically reserved for well-aligned nonunions with sufficient femoral head bone stock. The most common implant used for revision fixation is a sliding hip screw implant. The use of a short cephalomedullary nail (CMN) for revision fixation has not been previously reported. This article presents a technique for reamed short CMN revision fixation of well-aligned nonunions with sufficient bone stock that is a simpler and potentially less morbid treatment option compared to open procedures with fixed-angle devices. For nonunions with poor femoral head bone stock and/or malaligned fractures, a fixed-angle implant, with or without a valgus osteotomy, may be necessary, while arthroplasty is reserved for nonunions with poor proximal femur bone stock that are not amenable to fixed-angle implant fixation.
