Analysis of the effects and influence factors of primary total hip arthroplasty in the treatment of senile femoral neck fractures / 中国综合临床

ABSTRACT

Objective To analyze the effects and influence factors of primary total hip arthroplasty in the treatment of senile femoral neck fractures,and to increase the excellent rate of hip joint function recovery.Methods Retrospective analysis was applied to study the clinical data of one hundred and ten senile femoral neck fractures patients who underwent primary total hip arthroplasty in the 210th Hospital of People's Liberation Army from January 2014 to March 2016,to explore the main factors affecting postoperative recovery of hip joint function.Univariate analysis was used to analyze the factors influencing the clinical efficacy of the patients in terms of gender,age,body mass index,cause of injury,type of fracture and postoperative rehabilitation time,and Logistic regression analysis was used for multivariate analysis.Results The 110 senile femoral neck fractures patients obtained primary total hip arthroplasty,36 cases have seen excellent hip joint function recovery,54 good,15 fair,and 5 poor,with an excellent rate of 81.8 %(90/110).Single factor analyses found that body mass index,preoperative concomitant diseases,surgical approach,operation time,total blood loss, postoperative analgesia,discrepancy in bilateral lower limb lengths,postoperative rehabilitation time and postoperative complications were significantly related to hip joint function recovery(χ2=8.528,12.742,9.912, 8.131,10.404,10.171,12.406,6.412,10.362,P<0.05).According to the multivariate analysis,body mass index,surgical approach,total blood loss,postoperative analgesia,discrepancy in bilateral lower limb lengths,and postoperative rehabilitation time were the main factors affecting hip joint function recovery(Wald χ2=6.213, 4.543,9.156,6.287,5.461,3.698,95%CI=1.17~6.74,1.43~9.15,1.03~5.82,1.29~9.35,0.05~0.62, 0.12~0.93,P<0.05).Conclusion Primary total hip arthroplasty may lead to excellent curative effects for elderly patients with femoral neck fracture.Smaller body mass index,minimally invasive approach,less discrepancy in bilateral lower limb lengths,postoperative analgesia,less total blood loss and longer postoperative rehabilitation time may facilitate postoperative recovery for hip joint function.
