Is the Best Plate a Nail? A Review of 3230 Unstable Intertrochanteric Fractures of the Proximal Femur

By Tucker A, Donnelly KJ, Rowan C et al.

OBJECTIVES: 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). DESIGN: Multicentre National Prospective Cohort Study. SETTING: Northern Ireland. PATIENT/PARTICIPANTS: 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. INTERVENTION: 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. OUTCOME MEASURE: 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. RESULTS: 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). CONCLUSIONS: 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. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
