Hypothesis
Can spinopelvic mobility be reliably measured to improve acetabular cup placement in total hip arthroplasty?
Conclusion
The evaluation of spinopelvic mobility has good to excellent reliability and can be used for personalized acetabular cup placement.
Supporting Evidence
- The average pelvic incidence was 51.0 ± 13.1 degrees.
- The mean spinopelvic mobility was 27.3 ± 13.4 degrees.
- Measurements had good to excellent interobserver and intraobserver reliability.
- 20% of the patients had stiff spines, while 14% were hypermobile.
Takeaway
This study looks at how the movement of the spine and pelvis can help doctors place hip implants better, which might stop them from coming out of place.
Methodology
The study evaluated the spinopelvic motion of 116 patients using radiological assessments and developed a personalized target for acetabular cup placement based on these measurements.
Limitations
The study lacks clinical data to confirm that the suggested cup placement reduces dislocations and is based on a single center's cohort.
Participant Demographics
73% of the patients were women, and 80% had osteoarthritis.
