About

Intramedullary nailing is the standard treatment of trochanteric fractures. Mechanical failure such as cut-out and cut-through are associated with high rates of revision surgery, functional impairment and mortality. Augmentation of the implant have shown encouraging results in reducing the number of mechanical failures. The aim of the study was to evaluate the rate of mechanical failure of the cement augmented screws of TFNA nails.

A descriptive, retrospective, multi-operator, single-centre study was performed at our level 1 trauma centre. Patients were included if they were > 65 years of age, presented with a trochanteric fracture treated with an augmented TFNA nail. The primary outcome was fixation failure rate (cut-out or cut-through) at 3 and 6 postoperative months. Secondary endpoints were intraoperative data, clinical scores, and radiographic analysis.
