ObjectivesTo compare failure rates between short and long cephalomedullary nails used for the treatment of intertrochanteric hip fractures in patients over 65 years of age.DesignRetrospective cohort study. Data were collected from medical records and radiographs.SettingThree level 1 trauma centers.Patients/ParticipantsPatients aged 65 years or older who underwent treatment of an intertrochanteric hip fracture with a cephalomedullary nail between January 2004 and December 2010.InterventionOpen reduction and internal fixation of intertrochanteric hip fracture with either short or long cephalomedullary nail.Main Outcome MeasurementPostoperative treatment failure rate, defined as periprosthetic fracture or reoperation requiring removal or revision of nail, including conversion to arthroplasty.ResultsIncidence of treatment failure (periprosthetic fracture and reoperation requiring removal of nail) was 30 of 559 (5.4%) for the entire cohort; 13 of 219 (5.9%) occurred after placement of a short nail compared with 17 of 340 (5.0%) after placement of a long nail (P = 0.70). There were 11 of 559 (2.0%) patients who sustained a periprosthetic fracture after nailing, 6 of 219 (2.7%) after short nails and 5 of 340 (1.5%) after long nails (P = 0.35). The remaining 19 treatment failures were major reoperations requiring removal of nail, 7 of 219 (3.2%) after short nails and 12 of 340 (3.5%) after long nails (P = 0.81). The reasons for these 19 revision procedures were: screw/helical blade cutout (16), progressive arthritis with conversion to arthroplasty (1), avascular necrosis of femoral head with conversion to arthroplasty (1), and symptomatic leg length discrepancy with conversion to arthroplasty (1). Median follow-up period for patients living at least 1 year postoperatively was 30 months (range, 12-85 months). Overall, 175 of 698 (25%) patients died within 1 year after index surgery.ConclusionsWhen using contemporary cephalomedullary implants, short and long nails exhibit similar treatment failure rates.Level Of EvidenceTherapeutic Level III.
