Objectives:
This case-control study aimed to investigate standing sagittal spinopelvic alignment in patients with advanced hip osteoarthritis (HOA) and to determine whether their alignment differs from that of healthy individuals.
Methods:
This study included 240 participants, comprising 120 healthy individuals in the control group and 120 candidates for total hip arthroplasty due to primary HOA in the case group. Pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were measured in both groups using standing lateral X-rays.
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 degrees, respectively. In the control group, the mean PI, PT, and SS values in were 50.2 ± 8.1, 11.2 ± 5.5, and 39.1 ± 8.5 degrees, respectively. The P-value indicated no significant difference in spinopelvic parameters between the control and case groups.
Conclusion:
Our study demonstrated that standing spinopelvic parameters do not significantly differ between patients with primary HOA and healthy individuals.
