Abstract
Objectives: This case-control study aimed to investigate the sagittal spinopelvic alignment in patients with end-stage hip osteoarthritis (HOA) and understand whether the spinopelvic alignment is different from healthy individuals.
Methods: This study was piloted on 240 participants, 120 healthy individuals as the control group, and 120 candidates for total hip arthroplasty due to primary HOA as the case group. Pelvic incidence(PI), Sacral Slope (SS), and Pelvic Tilt (PT) were measured in both groups.
Results: The demographic characteristics of the two groups were not significantly different. In patients with primary HOA, the mean PI, PT, and SS angles were 52.3+10.1, 9.2+4.2 and 44.4+9.3. In the control group, The mean PI, PT and SS were 50.2+8.1, 11.2+5.5, and 39.1+8.5. The P-value indicated that no significant difference in spinopelvic parameters exists between the control and case groups.
Conclusion: Our study showed that standing spinopelvic parameters does not vary in patients with primary HOA from healthy individuals.
