Bottom Line: Mechanical failures and periprosthetic fractures were not observed in our series.Preinjury activity level was recovered in 78% of the patients.The unique design of the lag screw and its thread spacing had effectively reduced cut-out rate.

ABSTRACT
Geriatric hip fractures are one of the commonest fractures worldwide. The purpose of this study was to report the outcomes of a series of unstable geriatric hip fractures treated with AFFIXUS hip fracture nail. A retrospective study of 100 unstable geriatric hip fractures treated with AFFIXUS hip fracture nail is presented. The mean follow-up duration was 8 months (range 3-32). Of the patients 83% were female. The average age was 85 years. The fracture was treated by closed reduction and intramedullary fixation. The mean acute hospital stay was 17.6 days. Systemic complications occurred in 29 patients (29%) and local complications in 3 patients (3%) including lag screw cutout in one patient (1%), lag screw backout in one patient (1%), and deep infection in one patient (1%). Mechanical failures and periprosthetic fractures were not observed in our series. Fractures united in all patients. Preinjury activity level was recovered in 78% of the patients. The results of AFFIXUS hip fracture nail were satisfactory in most elderly patients. The unique design of the lag screw and its thread spacing had effectively reduced cut-out rate.

Mentions: AFFIXUS nail is available in 2 sizes, short (180 mm) and long (260–460 mm) (Figure 1); the unique thread spacing and lag screw design help to resist displacement and cutout. There is 10° of proximal anteversion built into the nail. The cannulated lag screw measures 10.5 mm in diameter for bone preservation. There is a choice of 125° and 130° neck angles to provide a range of anatomical options. The chamfer on the front distal tip facilitates insertion and decreases risk of stress on the anterior cortex in the distal femur. The 3° distal bend facilitates ease of insertion through the proximal intertrochanteric/subtrochanteric region. There is a preloaded set screw for ease of use and a 5.0 mm antirotation (AR) screw for rotational control. The shouldered lag screw and AR screw help preventing medial screw disengagement.
