253 patients scheduled for intramedullary nailing of a trochanteric fracture with the Proximal Femoral Nail Antirotation helical blade implant (PFNA; DePuy) were randomized to either receive or not receive additional cement augmentation of the device. The primary outcome was the functional performance on the Timed Up and Go test, while secondary outcomes included mobility and activities of daily living, radiographic results, and the incidence of complications. TUG test times were significantly shorter in the cement group at 6 months, but not 3 and 12 months; additionally, change in TUG test time from baseline did not significantly differ between groups at any follow-up. No implant-related complications were recorded in either group.
