Measure
Standard Treatment
Piriformis fossa entry portal for the antegrade nailing was used for this group. Received either a TRIGEN antegrade femoral nail manufactured by Smith \& Nephew (Memphis, Tennessee) or an Antegrade Femoral Nail manufactured by Synthes (West Chester, Pennsylvania)
Trigen
Trochanteric entry portal for the antegrade nailing was used for this group. These subjects received a TRigen Trochanteric Angegrade Nail (TAN) manufactured by Smith \& Nephew that incorporates a 4 degree valgus bend in the proximal aspect of the nail.
