To evaluate the functional outcomes, revision, and mortality rates of 3 implants used for unstable intertrochanteric hip fractures; the sliding hip screw (SHS), with or without a trochanteric stabilization plate (TSP); and a cephalomedullary nail (CMN).
Multicentre National Prospective Cohort Study.
Patients were identified from a prospective database. Fractures were classified according to OTA/AO A31A2.2, A2.3, and A3. All patients had a minimum of 12 months of follow-up.
Patients received either an SHS, an SHS in combination with a TSP, or a CMN. Implant choice was at the discretion of the operating surgeon.
Primary outcome was 12-month mortality analyzed by the Kaplan–Meier survival analysis. Secondary outcomes included 12-month functional status using a validated score and all time revision of implants for any reason.
In total, 3230 patients met the inclusion criteria (2474 SHS, 158 SHS + TSP, and 598 CMN). CMN use increased over time, with concomitant reduction in SHS use. There was no significant difference in functional outcomes at 12 months (analysis of variance, P = 0.177). Although men were significantly younger, they were at a higher risk of 12-month mortality. CMNs had statistically significantly lower 12-month mortality rates (P = 0.0148). The highest revision rate (4.04%) was seen in patients treated with SHS alone (P = 0.041).
The use of a CMN in unstable intertrochanteric hip fractures conveys the best results in functional outcomes, 12-month mortality, and has lower revision rates compared with an SHS ± TSP.
