RESUMEN
Intramedullary fixation using a short or long cephalomedullary nail (CMN) for treating hip fractures has gained popularity in recent years. We evaluated reoperation rates requiring device removal of short or long CMNs for patients 65 years and older. A retrospective study was performed at a level I trauma center over a 10-year period (2005-2015). Patients 65 years and older who were treated for intertrochanteric hip fractures with CMNs were included. This study included 893 patients (600 patients treated with a short CMN vs 293 treated with a long CMN). Patients in both cohorts were comparable in age, sex, and Injury Severity Score. There was no significant difference in comorbidities between the short and long CMN groups. Hospital length of stay (7.13 vs 6.88 days, P=.407) and intensive care unit length of stay (4.97 vs 4.63 days, P=.732) were not significantly different between the short and long CMN cohorts, respectively. The in-hospital mortality rate also did not vary between the 2 groups (1.3% for short CMN vs 2.7% for long CMN, P=.139). A significantly higher proportion of patients treated with a long CMN were discharged to a skilled nursing facility (63.4% vs 56.1%, P=.042). The overall reoperation rate was also comparable, 4.7% and 3.4% in the short CMN and long CMN groups, respectively (P=.367). No difference was found between the 2 treatment modalities (short or long CMN) for the elderly population. Both implants had similar rates of reoperation and implant failure. There is a cost consideration, with increasing length of the nail corresponding to increased cost. [Orthopedics. 2022;45(5):304-309.].
