Abstract:

BACKGROUND: Traditional operation frequently depends on experience of doctors and anatomic landmark visual observation, which often leads to deviation in acetabular prosthesis implantation. Computer navigation technique greatly improves accuracy of prosthesis implantation.
OBJECTIVE: To assess the accuracy and clinical significance of computer navigation for acetabular implantation in total hip arthroplasty.
METHODS: A computer-based online search of Cochrane Library, Medline, Embase, CBM, and CNKI was performed, and related Chinese journals were manually searched. Clinical trials were selected and analyzed using RevMan5.0.18 software.
RESULTS AND CONCLUSION: A total of 9 clinical trials were included, involving 695 cases. Meta analysis showed that compared with traditional surgery, acetabular component of computer navigation technology in total hip arthroplasty was more accurate in prosthesis position [RR=0.22, 95%CI(0.14-0.34), P < 0.000 01], the degree of inclination angles [RR=-1.76, 95%CI (-5.02 to 1.50), P=0.29], but no differences in the degree of anteversion angles [RR=-1.28, 95%CI (-5.68 to 3.12), P=0.57], and postoperative dislocation rate [RR = 1.25, 95%CI (0.05-31.66), P = 0.89]. There was no statistical difference between navigation applications and traditional surgery in the accuracy of acetabular position.
