Femoral Neck Fracture

The goal of this Randomized controlled trial is to evaluate in household ambulatory, elderly patients sustaining femoral neck fracture who are subjected to be treat with cementless bipolar hemiarthroplasty. The main questions it aims to answer are: * The efficacy in reducing blood transfusion for topical tranexamic acid administration * The safety of tranexemic acid, topically used As having undergone bipolar hemiarthroplasty surgery, participants will either receive retrograde intraarticular tranexamic acid injection via drain tube, or topical soaking administration. Researchers will compare, with standard procedure (procedure), whether topically administered tranexamic acid would reduce rate of blood transfusion.
