Background: Bipolar hemiarthroplasty is the standard of care for transcervical fracture in the elderly. Stainless steel being cheaper is preferred over titanium in developing nations for implants and prostheses. This study was conducted for assessing the short-term outcomes of uncemented bipolar hemiarthroplasty done using hydroxyapatite-coated stainless steel prosthesis. Methods: Sixty-five patients, >60 year of age operated between 2018 and 2020 at tertiary care centre with stainless steel (316L) completely coated with hydroxyapatite bipolar hemiarthroplasty implants were retrospectively followed up. Radiological outcomes were assessed based on pedestal formation, stem position, radiological limb length discrepancy, sinkage of stem, spot welds and stress shielding. Clinical and functional outcomes were assessed based on mean Harris Hip score. Results: Mean Harris Hip score at baseline, 3-week follow-up, 6-week follow-up, 3-month follow-up and 1-year follow-up was 45.9 (SD 2.5), 63.2 (SD 6.5), 75.1 (SD 9.9), 83.9 (SD 9.8) and 87.1 (SD 9.9), respectively. Excellent, good, fair, poor results were seen in 32.31, 40, 18.46, 9.23 of the patients, respectively. Valgus, central and varus stem position was seen in 49.23, 40, 10.77 percent of the patients, respectively. Pedestal formation, radiological limb length discrepancy, sinkage, spot welds, stress shielding was seen in 6.15, 32.31, 3.07, 53.85, 40 percent of the patients, respectively. Conclusion: Short-term outcomes of this study provides evidence that using a more affordable fully hydroxyapatite-coated stainless steel prosthesis for uncemented bipolar hemiarthroplasty is an appropriate treatment option for the transcervical femur fracture.
