This study was done in department of orthopedic- Surgery SMMAMC, sirajgonj from October 2016 to December 2018. A total 30 elderly patients with femoral neck fracture. Out of 30 patients 16 patients treated with unipolar hip prosthesis Group-I and 14 patients treated with bipolar prosthesis Group-II. In Group-I age ranges where 52 to 85 years average age 67.75 years and Group-II age ranges 51-81 years average 65 years. Out of 30 cases 19 (63.3%) were female and 11 (36.6%) were male. Average follow up was Group- I 10 months 10 days (range 8 months to 15 months) and Group- II 14 months 10 days (9 months to 18 months). Functional out come of treatment was analyzed by using the modified Harries hip rating system. In this study Group – I there were 5( 31.25%) excellent, 3( 18.75%) good and 6 (37.5%) fair and 2(12.5%) poor functional out come and in Group-II 7(50%) excellent, 5(35.7%) good and 1 (7.14%) fair and 1(7.14%) poor functional out come. Regarding final clinical out come in this series in Group-I 8 (50%) satisfactory and 8(50%) unsatisfactory result. In Group-II 12(85.71%) satisfactory and 2(14.28%) unsatisfactory result. Bipolar prosthesis with bone cement allows better fit of the stem in medullary canal and femoral head in the acetabulum. Approximation of ideal neck length greater range of movement, decrease stem loosing and acetabular erosion, less prosthetic pain and easy conversion of total hip revision than unipolar prosthesis [1].
