Hemiarthroplasty for fragile hip fractures in the elderly over 75 years old / 中华创伤杂志

ABSTRACT

Objective To investigate the key points of treating elder patients with hip fractures by hemiarthroplasty.Methods Clinical data of 138 elder patients with hip fractures undergone hemiarthroplasty between January 2008 and December 2010 were analyzed retrospectively.There were 43 males and 95 females at mean age of 82.8 years(range,75-103 years).Injury causes included fall from height(n=98),contusion(n=32)and sprain(n=8).There were 84 patients with femoral neck fractures(33 patients with Garden type Ⅲ,51 with type Ⅳ)and 54 patients with intertrochanteric fractures(three patients of Jensen-Evans type Ⅱ,six with type Ⅲ,25 with type Ⅳ,18 with type V,two with type R).Follow-up evaluation was performed using Harris scoring system.Results The ambulation period was average 4.5 days(range,3-12 days).Follow-up was average 24.4 months(range,10-45 months),which presented no loosening,subsidence or infection of prostheses.Due to additional trauma postoperatively,one patient suffered from prosthesis dislocation and two from fractures of distal prosthetic femoral shaft.Harris score at six months postoperatively was average 86.8 points(range,52-100 points),with excellent results in 42 patients,good in 59,fair in 19 and poor in five,with excellence rate of 80.8％.Conclusion With full accomplishment of peri-,intra-and post-operative measures,hemiarthroplasty is a suitable choice for treating hip fractures in the elderly patients.
