HighlightsCase of patient with reoperation after annuloplasty with Barricaid is provided.Transpedicular and interbody fixation reoperation was performed.Barricaid using for LDH reduces re-operation rate.
Objective: The aim of the study was to investigate the clinical and radiological results of using the annular closure device in patients with lumbar disc herniation (LDH). Methods: The study involved 120 patients with LDH operated on by limited discectomy and annular closure using the Barricaid device. A literature review was conducted to evaluate the effectiveness of the annuloplasty. Results: All patients showed postoperative regression of the radicular pain syndrome and were mobilized on the day of surgery. The correlation between the removed nucleus pulposus and changes in DHI was studied by linear regression. The results revealed that disc height loss is directly correlated with the volume of removed nucleus pulposus (p <0.05). Modic changes were present in 22 (22%) patients. Endplate changes (resorption and erosion) were present in 25 patients (20.7%). We found that these changes in MR and CT images have no effect on the clinical presentation of the disease. No intraoperative complications, such as severe hemorrhage requiring blood transfusion, or injury to the dura mater or nerve roots, were observed in our case series. Postoperative complications occurred in 3 (2.5%) patients. The reoperation rate was 4.2%. Conclusions: The use of the Barricaid annular closure device in 120 patients with lumbar disc herniation and high risk of recurrent herniation showed good clinical and radiographic outcomes. The reoperation rate in our study was 2.5%; disc reherniation at the operated level was observed in 1.7% of patients. This is a good outcome compared to the data reported for patients having a high risk of disc reherniation. Level of Evidence IV; Case series.
Background: Previous studies have demonstrated bone-anchored annular closure to significantly reduce reherniation and reoperation rates after lumbar discectomy in patients with large annular defects. It is important to identify the prognostic factors that may be associated with successful treatment. This study aimed to identify predictors of treatment success in patients with lumbar disc herniation treated with limited microdiscectomy supplemented by a bone-anchored annular closure device (ACD). Methods: This study was a retrospective analysis of 133 consecutive patients with lumbar disc herniation treated with the ACD. Treatment success was defined as !24% improvement in visual analog scale (VAS) for back pain, !39% improvement in VAS leg pain, and !33% in the Oswestry Disability Index (ODI), with the raw ODI score 48. Success was calculated at 3, 6, and 12 months after surgery. Potentially predictive outcomes included patient characteristics, operative data, and imaging outcomes, such as disc, facet, and end plate morphology. Logistic regression was used to determine the significant predictive factors for treatment success. Results: After 3, 6, and 12 months, 97 of 131 (74%), 104 of 129 (81%), and 112 of 126 (89%) patients, respectively, achieved the success criteria. At 3 months follow-up, a higher proportion of younger (17-40 years) versus older (41-65 years) patients met the success criteria (P ¼ .025). On the basis of logistic regression, the following factors were significantly associated with treatment success at 1 or more of the follow-up time points: sex (male), lower body mass index, higher baseline pain and ODI scores, lower grade preoperative disc degeneration, and the absence of a postoperative complication. The rates of index-level recurrent herniation and reoperation were 1.5% and 3.0%, respectively. Conclusions: This real-world evidence supports a promising benefit-risk profile for augmenting limited microdiscectomy with a bone-anchored ACD and provides some insights into the patient populations that may have a greater chance of realizing significant improvements in pain and function. Level of Evidence: 2 (Cohort study).
Longitudinal study of cervical MR in patients with degenerative disc disease (DDD). Objective. To evaluate the evolution of the degenerative changes in the C2-D1 cervical segments and to assess the association magnetic resonance imaging (MRI) parameters with clinical symptoms after surgical treatment in patients with DDD. Summary of Background Data. The evolution of degenerative changes in the cervical spine is poorly understood. Endplate defects can be of great importance in progressive disc degeneration (DD). Clarification of this predictor may be important in determining the treatment tactics in patients with DDD. Methods. The study included patients who had 2-years' followup after cervical fusion for spondylotic radiculo-with/without myelopathy. Demographic data (age, sex, surgical data) were assessed; clinical data (visual analogue scale [VAS] neck, VAS arm, Neck Disability Index [NDI]) and cervical MRI (DD grades by Pfirrmann, Modic changes (MC), total endplate scores (TEPS) were compared to preoperative data.Results. The median follow-up term was 26.5 (18.9-33.1) months. All patients reported a decrease neck pain and arm pain at follow-up (P < 0.001). There was observed the change in MC types (P < 0.001) and an increase of TEPS (P < 0.05). 71.7% discs remained unchanged during the follow-up, but a significant number of discs went from Grade 2 to Grade 3 and from Grade 3 to Grade 4 by Pfirrmann (P < 0.001). Clinical scores (VAS neck, VAS arm, NDI) had no correlation with MRI changes (P > 0.05). DD was associated with TEPS (odds ratio [OR] 2.05-5.47, P < 0.05) and patients' age (OR 1.11-2.33, P < 0.05) at all cervical levels; with MC types, but only at C4-C5 and C6-C7 levels (OR ¼ 2.91 and 2.79, respectively, P < 0.05). Receiveroperating characteristic analysis showed a TEPS threshold value of 7, above which the probability of DD significantly higher. Conclusion. During 2 years' follow-up the significant increase of DD grades by Pfirrmann was observed at C4-C6 levels (P < 0.001). A significant association DD with TEPS and age at all cervical levels was determined.
