Patients with flatback deformity had lower combined anteversion midpoint targets compared to those with normal spinopelvic alignment after total hip arthroplasty.
2
Stiff spinopelvic mobility resulted in a narrower acceptable anteversion range, indicating reduced compensatory pelvic motion during functional activities.
3
Greater pelvic incidence-lumbar lordosis mismatch was linked to lower midpoint combined anteversion values, with a 2-degree decrease for every 10-degree increase in mismatch.
4
The study suggests individualized acetabular component planning for patients with spinopelvic abnormalities to enhance impingement-free range of motion.
5
Limitations included postoperative assessment of spinopelvic alignment and lack of patient-reported outcomes, which may affect the study's conclusions.
