ABSTRACT: According to the literature, hip function after hip fracture is affected by the type of surgery. Our aim was to determine the correlation between surgical treatment of hip fracture and postoperative function in the elderly. Inclusion criteria were displaced hip fracture and age over 70 years. One hundred and twenty-nine participants were randomly divided into three groups according to the type of the surgical operation they underwent (hemi-arthroplasty [Merete, Berlin, Germany], total arthroplasty [Plus; De Puy, Warsaw, IN, USA] and internal fixation [Richards plate screw; Smith & Nephew, Memphis, TN, USA]). The function of the patients was estimated using the following parameters: the Barthel Index and Harris Hip Score, the range of passive hip motion, the gait speed of individuals, after 1 and 4 years of follow-up. The Barthel Index scores after 4 years of follow-up were 85.3, 82.6, 80.1 after total arthroplasty, hemi-arthroplasty and internal fixation respectively. Similarly, the Harris Hip Scores after 4 years of follow-up were 83.7, 79.5 and 73.6. The range of passive hip motion in the three groups of patients did not differ significantly (p>0.05). Also, patients of the total arthroplasty and hemi-arthroplasty groups walked faster than the patients of the internal fixation group 4 years after discharge (p<0.05). In conclusion, we believe that total hip arthroplasty is the treatment of choice for displaced subcapital hip fractures in patients over 70 years old.
