Summary: | To compare functional and clinical outcomes in patients with pertrochanteric hip fractures treated with either a short (SN) or long (LN) cephalomedullary nail.
Prospective, randomized.
Clinical investigation was performed at the Mayo Clinic's Level 1 Trauma Center in Rochester, MN.
Two hundred twenty patients with intertrochanteric fractures were prospectively randomized to an SN or LN cohort. A total of 168 patients (SN, n = 80; LN, n = 88) had a mean follow-up of 13.9 months. Fifty-two patients did not meet the minimum 3-month follow-up. Demographics were comparable between the cohorts.
The primary outcome measurement was functional outcome evaluated by Short Form (SF-36) and Harris Hip scores (HHS) at 3 months. Secondary outcomes included implant failure, peri-implant fracture, mortality, operative time, estimated blood loss, and reoperation.
SN and LN cohorts were comparable in all aspects of the SF-36. There was a clinically insignificant difference in the HHS between cohorts. Patients treated in the SN cohort experienced shorter operative times but did not differ in tip-to-apex distance or subtrochanteric fracture extension. There was no difference in implant cutout, deep surgical site infection, or peri-implant fractures.
Patients treated with SNs or LNs for pertrochanteric femur fractures experienced comparable functional outcomes as measured by SF-36 and HHS. When compared with the LN cohort, SN patients experienced no difference in peri-implant fracture or lag-screw cutout and tolerated up to 3 cm of subtrochanteric fracture line extension.
