Objective：This study aims to explore the feasibility，safety，initial stability and early clinical efficacy of dual mobility cup total hip arthroplasty for the hip reconstruction. Methods：Total 25 patients with the fresh femoral neck fracture （9 male and 16 female），with age of （70.20±6.94） years old，were treated with dual mobility cup THA from January 2019 to June 2019. The operative duration，intraoperative blood loss，postoperative blood loss complications were recorded. All patients were followed up postoperatively. Visual analogue scule（VAS），Harris hip score（HHS） and Mayo hip score（MHS） were recorded to evaluate the improvement of hip local pain and recovery of hip function. Results：Patients were postoperative follow-up in time with an average of （13.55±0.99） months. The mean operative duration was （1.36±0.25） h；the mean blood loss was （275.00±77.17） mL and the mean postoperative blood loss was （236.11±76.32） mL；The X-ray of the postoperative hip joint showed that the joint prosthesis was in good position，the force line of the joint recovered satisfactorily，and the joint prosthesis was in close contact with the bone contact surface without any gaps. The mean VAS scores ranged from （5.61±0.97） points preoperatively to （0.11±0.12） points（t=26.92，P＜0.001）at 12 months postoperatively. The average HHS ranged from （3.77±1.40） points preoperatively to （91.83±4.88） points（t=-86.73，P＜0.001）at 12 months postoperatively. The average MHS was （89.10±5.22） points at 12 months postoperatively. None of the patients had any complications related to surgery，such as vascular nerve injury，infection，dislocation of prosthesis，vascular embolization. Conclusion：The preliminary clinical result of dual mobility cup total hip arthroplasty is satisfactory for the hip reconstruction，increasing the stability of the hip joint，and restoring the function of the postoperative hip joint.
