intertrochanteric fractures (itfs) in the elderly are still a big challenge for clinical doctors. Although proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty (BPH) are selected by most of the orthopaedic surgeons for elderly ITFs patients, there is still no consensus on the superiority of PFNA and BPH for ITFs in elderly. In this study, we hypothesized that BPH should not be selected as the primary option for ITFs in elderly patients, and analyzed clinical data of 202 elderly ITFs patients aged 80 years or more treated with PFNA (Group A) and BPH (Group B) to compare the early outcome of PFNA and BPH for ITFs in elderly patients aged 80 years or more. We found that operation time and blood loss during surgery in group A are less than in Group B. Time of weight bearing after operation in Group A is longer than in Group B. Incidence of complications 2 weeks after operation in Group A is 9.29% less than 25.81% in Group B (χ 2 = 9.539, p = 0.002). Mortality rates 12 months after operation in Group A is 11.43% similar with 19.35% in Group B (χ 2 = 2.261, p = 0.133). Harris Hip Score 12 months after operation in Group A is 68.00 ± 29.11 points similar with 65.73 ± 33.29 points in Group B (t = 0.490, p = 0.625). Therefore, for elderly ITFs patients aged 80 years or more, BPH should not be selected as the primary option for itfs in elderly patients.
This study aimed to compare the early outcome of proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty (BPH) in elderly intertrochanteric fractures (ITFs) patients aged 85 years or more. This is a prospective cohort study, and we analyzed 120 elderly patients aged 85 years or more presented with ITFs who underwent BPH and PFNA between January 2017 and July 2018. 84 patients treated with PFNA were set as Group A, and 36 patients treated with BPH were set as Group B. Data such as gender, age, period of follow-up, fracture classification (according to Evans-Jensen classification), preoperative ASA (American Society of Anesthesiologists) physical status, interval between injury and operation, method of anaesthesia, duration of operation time, blood loss during surgery, time of weight bearing after operation, incidence of complications 2 weeks after operation, mortality rates and Harris Hip Score 12 months after operation were recorded and compared. There are no statistically significant differences when compared general data in patients from group A and B ( P > .05). Operation time in Group A is less than Group B (103.33, 40–230 min vs 122.64, 75–180 minute, P < .01). Blood loss during surgery in Group A is less than Group B (70.24, 50–100 mL vs 194.44, 100–500 mL, P < .01). Time of weight bearing after operation in Group A is longer than Group B (50.70, 7–100 days vs 6.67, 4–14 days, P < .01). Incidence of complications 2 weeks after operation in Group A is less than Group B (14.12% vs 36.11%, P < .01). Mortality rates 12 months after operation in Group A is similar with Group B (13.10% vs 19.44%, P > .05). Harris Hip Score 12 months after operation in Group A is similar with Group B (64.64,0–91 points vs 64.41, 0–90 points, P > .05). Although BPH and PFNA have similar functional outcome and mortality rates 12 months after operation, BPH has more postoperative complications in elderly patients aged 85 years or more with ITFs, Bipolar Hemiarthroplasty should not be selected as the primary option for ITFs in elderly patients aged 85 years or more.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
