Abstract:
BACKGROUND: To solve the dislocation following hip arthroplasty, a double mobility acetabular prosthesis has been developed, and its effect still needs to be confirmed through follow-up observation.OBJECTIVE: To explore the early clinical effectiveness of total hip replacement with double mobility acetabular prosthesis.METHODS: Thirty patients admitted from January 2013 to November 2015, were given total hip replacement with double mobility acetabular prosthesis, and were then followed up for 1 year. The hip function and loosening were evaluated by Harris hip scores, Beijing program scaling and imaging examination.RESULTS AND CONCLUSION: (1) All patients were followed up for 1 year. (2) The mean Harris hip score was significantly increased from preoperatively (39.7±3.87) to postoperatively (93.6±3.82), and the mean score of the Beijing program scaling was also significantly increased from (10.5±2.46) to (17.3±1.87) (both P < 0.05). (3) All patients suffered from moderate to severe pain before replacement, and 28 patients complained mild or no pain and 2 patients with moderate pain after operation. X-ray showed a stable hip. (4) To conclude, the total hip arthroplasty with double mobility acetabular prosthesis achieves satisfactory short-term treatment outcomes, but its long-term effect needs to be observed further.
