ABSTRACT
BACKGROUND:
During total hip arthroplasty, placement angle of acetabular prosthesis is significant for clinical curative effects.OBJECTIVE:
To investigate the abduction angle and anteversion angle of acetabular prosthesis at different positions during total hip arthroplasty and related influential factors.METHODS:
Thirty-five patients undergoing total hip arthroplasty were included in this study, containing 21 males and 14 females, at the age of 51-75 years old. Thesame patient at different positions underwent X-ray examination, including standing anteroposterior pelvis radiographic imaging, standing lateral radiographic imaging and supine anteroposterior pelvis radiographic imaging. Abduction angle and anteversion angle of acetabular prosthesis were measured. RESULTS ANDCONCLUSION:
(1) Abduction angle and anteversion angle at standing positionwere bigger than that at supine position (48.47°, 45.89°; 12.44°, 6.17°;P< 0.05). (2) The change in anteversion angle wasassociated with pelvic incidenceangleand pelvic tiltangle. The change in abduction angle was associated with pelvic obliquity. (3) The range of abduction angle (40±10)° and anteversion angle (15±10)° of acetabular prosthesis was identified as securityzone. (4) Results suggested that there were changes in acetabular abduction angle and anteversion angle between supine anteroposterior pelvis radiographic imaging and standing anteroposterior pelvis radiographic imaging after total hip arthroplasty. Acetabular angle was associated with pelvic obliquity, pelvic incidence and pelvic tilt.
