Previous studies have demonstrated bone-anchored annular closure to significantly reduce reherniation and reoperation rates after lumbar discectomy in patients with large defects. It is important identify the prognostic factors that may be associated successful treatment. This study aimed predictors of treatment success disc herniation treated limited microdiscectomy supplemented by a device (ACD).This was retrospective analysis 133 consecutive ACD. Treatment defined as ≥24% improvement visual analog scale (VAS) for back pain, ≥39% VAS leg ≥33% Oswestry Disability Index (ODI), raw ODI score ≤48. Success calculated at 3, 6, 12 months surgery. Potentially predictive outcomes included patient characteristics, operative data, imaging outcomes, such disc, facet, end plate morphology. Logistic regression used determine significant success.After months, 97 131 (74%), 104 129 (81%), 112 126 (89%) patients, respectively, achieved criteria. At 3 follow-up, higher proportion younger (17-40 years) versus older (41-65 met criteria (P = .025). On basis logistic regression, following were 1 or more follow-up time points: sex (male), lower body mass index, baseline pain scores, grade preoperative degeneration, absence postoperative complication. The index-level recurrent 1.5% 3.0%, respectively.This real-world evidence supports promising benefit-risk profile augmenting ACD provides some insights into populations greater chance realizing improvements function.2 (Cohort study).
