RESUMO
Objective To compare the clinical outcomes of long and short InterTan intramedullary nailing of senior intertrochanteric hip fracture in conjunction with early total care (ETC).Methods In this prospective study, records of 30 elder patients with intertrochanteric fracture hospitalized between January 2011 and September 2013 were included.Using the concept of ETC, the patients were treated with long (long-nail group, n =15) and short InterTan intramedullary nails (shortnail group, n =15) within 72 hours postinjury.The two groups were compared for operation time, intraoperative blood loss, fracture healing time, Harris hip score, time to pre-injury mobilization and hardware failure rate.Results Operation time was (77.25 ± 7.38) minutes in long-nail group versus (72.10 ± 6.90) minutes in short-nail group (P ＜ 0.01).Time to pre-injury mobilization was (7.45 ± 1.61) months in long-nail group versus (8.57 ± 2.18) months in short-nail group (P ＜ 0.05).There were no significant differences between long-and short-nail groups regarding the blood loss [(180.75 ± 38.26)ml vs (178.62 ± 34.79)ml], fracture healing time [(4.82 ± 1.12)months vs (4.76 ± 1.04) months], and Harris hip score [(83.75 ± 1.71) points vs (82.57 ± 2.18) points] (P ＞ 0.05).Conclusions Either long or short InterTan intramedullary nailing combined with ETC is effective in treatment of intertrochanteric hip fracture in the elderly.However patients treated with long nails return to pre-injury mobilization relatively earlier.Long InterTan intramedullary nail system is better for the patients combined with serious osteoporosis.
