Abstract


Background: Fracture neck of the femur leads to significant morbidity and mortality in elderly population. Various surgical options are available for the treatment in the elderly, but the gold standard between Austin Moore’s prosthesis and bipolar prosthesis is always debated. Hence, we designed a short-term prospective study to compare the monopolar and bipolar hemiarthroplasty in the elderly having fracture neck of the femur.
Materials and Methods: We conducted a prospective study at a tertiary hospital between 2017 and 2019. In our study, we enrolled 30 patients in each group. Patients in Group A (monopolar) underwent Austin Moore’s hemiarthroplasty and in Group B (Bipolar) underwent uncemented bipolar hemiarthroplasty by standard posterolateral approach. Patients were treated by standard protocols and analyzed at regular intervals with final assessment done at the end of 1 year. Functional outcome was evaluated using Harris Hip Score.
Results: Out of total 60 patients, 51 were evaluated at the end of 1 year. Mean age of population was 66.58 ± 5.96 in monopolar and 64.68 ± 7.48 in bipolar group. Harris Hip Score was 86.58 ± 5.42 in monopolar and 88.52 ± 3.08 in bipolar group. Pain was 38.69 ± 3.58 in monopolar and 40.20 ± 1.50 in bipolar group. Functional status was 39.72 ± 3.00 in monopolar group and 39.58 ±3.45 in bipolar group. Excellent outcome was noted in 13 of monopolar and 15 of bipolar patients seven 7 complications in monopolar and six in bipolar group, respectively.
Conclusion: In our study, we had comparable functional (Harris Hip Score) results in the monopolar and bipolar prosthesis groups, though more excellent outcomes and less complications were encountered in the bipolar group than monopolar which is statistically insignificant at the end of 1 year.
