Abstract: BACKGROUND: For elderly patients with femoral neck fractures with hemiplegia, the economic cost of using restrictive acetabular linings in total hip arthroplasty is relatively low and has a strong anti-dislocation mechanism, which can theoretically restore the patient’s lower limb function and reduce occurrence of posterior dislocation. OBJECTIVE: To investigate the short-term clinical efficacy and feasibility of total hip arthroplasty with restrictive lining in elderly patients with femoral neck fractures with hemiplegia. METHODS: Seven elderly patients with femoral neck fractures and hemiplegia admitted to the Quanzhou Orthopedic-Traumatological Hospital of Fujian University of Traditional Chinese Medicine from March 2015 to January 2019 were enrolled, including three males and four females, at the age of 66-77 years old. Pinnacle ES Stable and Enhanced Lined Hip Joint System was used for total hip arthroplasty. The operation time and blood loss were recorded. The function of the hip joint was evaluated by Harris score. The loosening and dislocation of the prosthesis were observed by imaging examination. This study was approved by the Ethics Committee of Quanzhou Orthopedic-Traumatological Hospital of Fujian University of Traditional Chinese Medicine. RESULTS AND CONCLUSION: (1) The operation time of seven patients was (77.1±14.4) minutes, and the intraoperative blood loss was (350±119) mL. (2) All seven patients were followed up without drop out, and the follow-up time was (32.9±9.0) months. During follow-up, there were no signs of prosthesis loosening or polyethylene wear, and no complications, such as pulmonary embolism, dislocation, and infection. At the last follow-up, the Visual Analogue Scale score of seven patients was 0, and the average Harris score was (80.3±6.2). (3) It is a reasonable and effective method to treat the hemiplegia elderly patients undergoing total hip arthroplasty using the stable and enhanced lined hip joint system for femoral neck fractures.
