Effect total hip arthroplasty and hemiarthroplasty in treatment of displaced femoral neck fractures in elderly

Abstract

Objective To investigate the effect total hip arthroplasty and hemiarthroplasty in treatment of displaced femoral neck fractures in elderly .Methods 83 cases of elderly patients with displaced femoral neck fractures were divided into two groups according the order randomly.The control group（n=53） was given hemiarthroplasty while the observation group （ n=30） took total hip arthroplasty .The clinical efficacy and occurrence of complications after surgery were compared.Results The observation group excellent rate was 90.00%（27/30）, significantly higher than the 79.25%（42/53） （χ2 =11.23,P〈0.05）;The observation group′s operative time,blood loss and postoperative drainage were （145.33 ±6.21）min,（575.65 ±26.84）mL and （278.51 ±14.15）mL,which was more than the control group（80.12 ±5.36）min,（322.52 ±25.34）mL and （185.46 ±12.48）mL significantly（t=9.56, 8.83,10.03,all P〈0.05）;The observation group′s incidence of complications was 10.00%（3/30）,which was sig-nificantly lower than the control group′s 22.64%（12/53） （χ2 =12.16,P 〈0.05）.Conclusion The total hip arthroplasty has a significant effect in the treatment of femoral neck fractures in elderly ,patients have good recovery of joint function with a low incidence of complications which can be used as the preferred solution for clinical treatment .
