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.

Inclusion Criteria:

• > 65 years of age
• a trochanteric fracture that occurred through a low-energy mechanism
• an augmented TFNA nail

Exclusion Criteria:

• pathological fracture
• open fracture
• hips with pre-existing deformities other than osteoarthritis
• a history of hip surgery
• an insufficient quantity of injected cement (< 3 mL).

The study population consisted of 61 patients. The analyses were therefore based on 45 patients (Table 1). The 38 women and 7 men had a mean age of 82.84 years (65-102, 9.50) and most had sustained AO/OTA 31-A1.2 fractures.

All collected data that underlie results in a publication.

Data will be available beginning three years and ending five years following the final study report completion.

Data access request will be reviewed by the internal committee of Brest University Hospital. Requestor will be required to sign and complete a data access agreement.
