The functional outcome in patients treated with THA with acute fracture neck of femur in patients aged above 60 years using Harris hip score

The incidence of femoral neck fractures is increasing continuously among the aging population. The numbers of hip fracture are expected to increase from 1.7 million in 1990 to 6.3 million during the year 2050. The femoral neck fractures and pertrochanteric fractures are of approximately equal incidence and together make up to 90% of the proximal femur fractures and the remaining 5 – 10% is subtrochanteric. A total 40 patients with acute fracture of neck of femur aged above 60 years treated with THA attending the Department of Orthopedics, constituted the sample size. The sample size was calculated by assuming a Harris hip score of 81 points with a standard deviation of 5, with a relative precision of 2% (Alpha of 5%, 95% confidence interval). The Harris hips score was 81.82 at the end of 6 months of follow up, 86.07 at the end of 3 months and 91.1 at the end of 6 months. The mean difference in Harris Hip score between the 6 weeks versus 3 months was 4.25, 9.27 between 6 weeks versus 6 months and 5.02 between 3 months versus 6 months. There was a statistically significant difference in the Harris Hip score in the period of follow up.
