Full-Endoscopic Sacroiliac Joint Denervation for Painful Sacroiliac Joint Dysfunction: A Prospective 2-Year Clinical Outcomes and Predictors for Improved Outcomes. Neurosurgery 2024:00006123-990000000-01239. [PMID: 38916375 DOI: 10.1227/neu.0000000000003053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Accepted: 04/26/2024] [Indexed: 06/26/2024] Open
Abstract
BACKGROUND AND OBJECTIVES Full-endoscopic sacroiliac joint denervation (FE-SJD) is a novel technique for the management of pain secondary to sacroiliac joint dysfunction. The aim of this study was to assess the long-term efficacy, safety, clinical outcomes, and outcome predictors of uniportal full-endoscopic sacroiliac joint denervation. METHODS From 2019 to 2021, a total of 47 consecutive patients with pain secondary to sacroiliac joint dysfunction underwent uniportal FE-SJD through posterior approach by a single fellowship-trained spine surgeon. A retrospective analysis of perioperative parameters, complications, and clinical outcomes were obtained prospectively. RESULTS The patient cohort had a mean age of 59.4 ± 14.0 years, with 63.8% females. Symptom duration averaged 62.1 ± 53.7 months. The mean operative time was 57.1 ± 16.8 minutes. All patients were discharged on the same day of surgery. Significant improvement was noted in preoperative visual analog score (back) and Oswestry Disability Index scores at 3, 6, 12 months, and 2 years (P < .001). Thirty-four patients (72.3%) returned to normal functioning with an average of 82% pain relief and a satisfaction rate of 78.7% at a mean follow-up of 18.2 ± 13.1 months. There were no intraoperative complications. One patient had postoperative right L5 dysesthesia. Seven patients (14.9%) underwent contralateral FE-SJD due to satisfaction with the index procedure but residual pain on the contralateral side. Concomitant lumbar issues correlated with less functional improvement at 2 years (P = .009). CONCLUSION The long-term clinical results of FE-SJD are favorable. Endoscopic denervation of the dorsal rami branches supplying the sacroiliac joint represents a safe, effective, and durable option to address pain secondary to sacroiliac joint dysfunction. A significant factor that influences outcomes is the presence of concomitant lumbar pathology. Further research is needed to compare this technique with current available treatment options.

[PMID: 38886996 PMCID: PMC11187614 DOI: 10.7602/jmis.2024.27.2.55] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 05/29/2024] [Accepted: 06/07/2024] [Indexed: 06/20/2024]
Abstract
Recently, there has been considerable progress in developing new technologies and equipment for the medical field, including minimally invasive surgeries. Evaluating the effectiveness of these treatments requires study designs like randomized controlled trials. However, due to the nature of certain treatments, randomization is not always feasible, leading to the use of observational studies. The effect size estimated from observational studies is subject to selection bias caused by confounders. One method to reduce this bias is propensity scoring. This study aimed to introduce a propensity score matching process between two groups using a practical example with R. Additionally, Rex, an Excel add-in graphical user interface statistical program, is provided for researchers unfamiliar with R programming. Further techniques, such as matching with three or more groups, propensity score weighting and stratification, and imputation of missing values, are summarized to offer approaches for more complex studies not covered in this tutorial.

J Orthop Surg Res 2024; 19:341. [PMID: 38849922 PMCID: PMC11162081 DOI: 10.1186/s13018-024-04831-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Accepted: 06/02/2024] [Indexed: 06/09/2024] Open
Abstract
BACKGROUND Percutaneous endoscopic lumbar discectomy (PELD) has demonstrated efficacy in alleviating leg pain among patients with lumbar disc herniation. Nonetheless, residual back pain persists as a troubling issue for surgeons following the procedure. In the treatment of discogenic back pain, sinuvertebral nerve radiofrequency ablation has shown promising results. Nevertheless, the potential benefit of simultaneously implementing sinuvertebral nerve radiofrequency ablation during PELD surgery to address residual back pain has not been thoroughly investigated in current literature. METHODS This retrospective study reviewed Lumbar disc herniation (LDH) patients with low back pain who underwent combined PELD and sinuvertebral nerve ablation in our department between January 2021 and September 2023. Residual low back pain post-surgery was assessed and compared with existing literature. RESULTS A total of 80 patients, including 53 males and 27 females, were included in the study. Following surgical intervention, patients demonstrated remarkable improvements in pain and functional parameters. One month post-operatively, the VAS score for low back pain exhibited a 75% reduction (6.45 ± 1.3 to 1.61 ± 1.67), while the VAS score for leg pain decreased by 85% (7.89 ± 1.15 to 1.18 ± 1.26). Notably, the JOA score increased from 12.89 ± 5.48 to 25.35 ± 4.96, and the ODI score decreased form 59.48 ± 9.58 to 20.3 ± 5.37. These improvements were sustained at three months post-operatively. According to the modified Mac Nab criteria, the excellent and good rate was 88.75%. Residual low back pain is observed to be comparatively reduced compared to the findings documented in earlier literature. CONCLUSION The combination of percutaneous endoscopic lumbar discectomy and sinuvertebral nerve ablation demonstrates effective improvement in low back pain for LDH patients.

Abstract
STUDY DESIGN Randomized controlled trial. OBJECTIVES To compare the effect and safety of 2 anesthetic methods using in the operation of Transforaminal Endoscopic Lumbar Discectomy. METHODS From the January of 2020 to the December of 2021, 230 consecutive patients that underwent TELD were applied with two methods of anesthesia. All the patients were divided into two groups. The Monitored Anesthesia Care (MAC) group used the local anesthesia (LA) with MAC that based on the combination of dexmedetomidine and butorphanol tartrate. The LA group used the local anesthesia only. Then the Visual Analogic Scale (VAS) through the operating period was compared between the two groups at the time points of before operation (T0), inserting of the puncture needle (T1), establishing of the working cannula (T2), excision of the fibrous rings (T3) and immediately postoperatively (T4). Also, the satisfaction degree of the patients for the course of the operations and the occurrence of the complications were compared between the two groups. RESULTS There were no differences of the VAS around the operating area at the time point of T0. Then the MAC group expressed lower scores at all other points of T1, T2, T3 and T4. Then the satisfaction degree of the MAC group was superior than the LA group. No difference was observed for the occurrence of the complications. CONCLUSIONS MAC based on the combination of dexmedetomidine and butorphanol tartrate is an ideal method of anesthesia for TELD with enough effect and safety.

Abstract
Background This study evaluates the factors affecting the return to work of endoscopic surgery for lumbar foraminal stenosis (LFS), including symptoms, functional status, complications, and reoperation rates. Methods The authors' retrospective cohort study included 100 consecutive patients (50 males and 50 females) diagnosed with LFS who underwent endoscopic surgery at Trotsky National Research Center of Surgery between January 2018 and December 2021. Results There were no significant differences in age and preoperative visual analog scale and Oswestry disability index scores between the male and female groups, time to return to work for different patient groups after undergoing endoscopic lumbar foraminotomy (ELF). However, patients with more severe stenosis and comorbidities may take longer to recover. Confounding factors were patient age, preoperative physical function, and job requirements. Conclusion This study confirms that study ELF can effectively improve symptoms associated with lumbar radiculopathy, as well as back pain, and improve patients' quality of life. Comorbidity, smoking status, and complications prolong the time to return to work following ELF surgery compared to healthy subjects.
