Abstract:
BACKGROUND:In total hip arthroplasty, the accurate placement of the acetabulum is needed to guarantee the survival rate of the prosthesis and improve the prognosis. In order to ensure the accurate placement of the acetabulum, the accurate measurement of the abduction angle and the anteversion angle of the acetabulum is needed. OBJECTIVE:To investigate the application value of C-arm X-ray displacement measurement of acetabular anteversion angle and abduction angle in total hip arthroplasty. METHODS:Total y 63 cases undergoing total hip arthroplasty were divided into two groups according to their wil . Patients in the control group (n=30) were implanted with traditional acetabular prosthesis locator. Patients in the observation group (n=33) were implanted with acetabular prosthesis after C-arm X-ray displacement measurement. Acetabular anteversion angle, abduction angle and pelvic inclination were measured before, during and after arthroplasty. Acetabular anteversion angle and abduction angle were measured in both groups after arthroplasty. Pain score and hip function Harris score were recorded in both groups at different time points. RESULTS AND CONCLUSION:(1) No significant difference in acetabular anteversion angle, abduction angle and pelvic inclination was detected before, during and after arthroplasty (al P>0.05). (2) No significant difference in abduction angle was determined between the two groups after arthroplasty (P>0.05), but acetabular anteversion angle was significantly smal er in the observation group than in the control group (P<0.05). (3) At 7 days after arthroplasty, Visual Analog Scale scores were less in the observation group than in the control group (P<0.05). (4) Compared with that before arthroplasty, Harris score was significantly higher after arthroplasty in both groups (P<0.05). Harris score was higher in the observation group than in the control group at 3 and 12 months after arthroplasty (P<0.05). (5) Results indicated that during total hip arthroplasty, C-arm X-ray machine can measure acetabular anteversion angle and abduction angle, and effectively correct pelvic inclination, internal and external rotation, abduction and adduction, improve the accuracy of acetabular cup placement and the quality of replacement surgery, and improve the prognosis of the patients.
