Internal fixation versus hemiarthroplasty versus total hip arthroplasty for displaced subcapital fractures of femur--13 year results of a prospective randomised study.
In this prospect i ve r and omised trial we compare the mortality , morbidity and functional results of patients following each of the three principal methods of treatment for displaced subcapital fractures of the femur . Two hundred and ninety patients over the age of 65 years were included and r and omly allocated to undergo closed reduction and internal fixation with a sliding compression screw plate or uncemented Austin Moore hemiarthroplasty or cemented Howse II total hip arthroplasty ( THA ) .  Nineteen patients were subsequently excluded . The 13 year results show that there was no statistical difference in the mortality between the three groups ( 81 , 85 and 91 % respectively ) . Internal fixation and hemiarthroplasty groups fared poorly with a revision rate of 33 and 24 % , respectively , compared with 6.75 % in the THA group . The dislocation rate was 13 % following hemiarthroplasty and 20 % following THA .  Average Harris hip scores were 62 , 55 and 80 , respectively , for the internal fixation , hemiarthroplasty and THA groups . In the long term , both internal fixation and hemiarthroplasty result ed in a poor outcome with respect to pain and mobility . Despite high early complications , THA result ed in least pain and most mobility both in the short and long-term and was encouraging with a revision rate of only 6.25 % . THA should be seriously considered in physiologically active patients with a displaced subcapital fracture of the femur
