Are Standing Spinopelvic Parameters Different in Patients with Hip Osteoarthritis Compared to Healthy Individuals? A Comparative Study

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 ۲۴۰ participants, comprising ۱۲۰ healthy individuals in the control group and ۱۲۰ 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 ۵۲.۳ ± ۱۰.۱, ۹.۲ ± ۴.۲, and ۴۴.۴ ± ۹.۳ degrees, respectively. In the control group, the mean PI, PT, and SS values in were ۵۰.۲ ± ۸.۱, ۱۱.۲ ± ۵.۵, and ۳۹.۱ ± ۸.۵ 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.         Level of evidence: III
