| The performance of spino-pelvic stabilization with the PERLA® TL System will be evaluated with the measurements of the following radiographic parameters on full spine x-ray or electro-optical system (EOS) x-ray, defined as below: 1. The correction of the sagittal lumbar lordosis (L1-S1) between the preoperative and postoperative follow-up visits 2. Pelvic incidence (PI) at the preoperative and postoperative follow-up visit 3. Pelvic tilt (PT) at the preoperative and postoperative follow-up visit 4. Sacral slope at the preoperative and postoperative follow-up visit 5. Sagittal vertical axis (SVA) at the preoperative and postoperative follow-up visit 6. Thoracic kyphosis (T4-T12) at the preoperative and postoperative follow-up visit 7. Coronal Cobb angle correction (in case of deformity) between the preoperative and postoperative follow-up visit 8. Interbody fusion at the level treated, as applicable (if interbody device implanted), at postoperative follow-up visit 9. Pelvic incidence - lombar lordosis (PI-LL) Mismatch at the preoperative and postoperative follow-up visit The clinical benefits of spino-pelvic stabilization with the PERLA® TL System were evaluated using Patient Reported Outcomes (PRO) with the following endpoints: 1. Pain reduction was measured using the Visual Analog Scale (VAS back and leg) self-reported questionnaire at the postoperative visits compared to the preoperative visit (as applicable) 2. Functional capacity improvement was measured using the Oswestry Disability Index (ODI) self-reported questionnaire at the postoperative visits compared to the preoperative visit (as applicable) | — |
