Abstract Background: This research aims to discuss the clinical application value of the superior articular process osteotomy navigation (SapON) technique in percutaneous endoscopic lumbar discectomy.Methods: Patients who underwent intervertebral foraminal endoscopic surgery for degenerative disease of the lumbar spine were collected and divided into two groups from March 2016 to May 2018. Group I: 69 patients were treated by the SapON technique. Group II: 53 patients were treated by Transforaminal Endoscopic Spine Surgery (TESS) technique. Fluoroscopy times, the time of establishment working channel, endoscopic operations, and entire operations in two groups were recorded. Patients' clinical curative effect was evaluated by visual analog scale (VAS) scores, Oswestry disability index(ODI), and MacNab standard at different time points, including before surgeries, one day, three months after surgeries, and the last follow-up time.Results: Operations were all successful both in groups I and II. Fluoroscopy times, establishing the working tunnels time, endoscopic operations time, and entire operations time and other indexes between the two groups were statistically significant. Patients’ low back, legs pain VAS scores, and ODI one day, three months after surgeries, and at the last follow-up in both two groups were significantly lower than those before operations with a statistical difference. The excellent rate in groups I and II were 98.55% and 96.23%. Complications were not observed in group I, while in group II, only one patient suffered the injury of the right L5 nerve root, and recovered after three months’ conservative treatment.Conclusion: The application of SapON in percutaneous endoscopic lumbar discectomy (PELD) has its advantages to popularize in clinical work, including operating simply and orderly, high safety, fewer complications, lower radiation exposure, and good clinical effects

Background: Percutaneous endoscopic lumbar discectomy (PELD) has become an increasingly popular minimally invasive spinal surgery. Due to the technical evolution of PELD, the focus of decompression has shifted from the central nucleus to the subannular-protruded disc herniation, which allows direct neural decompression. Surgical entry into the spinal canal leads to the greater possibility of bony structure obstruction, thus the location and direction of the working channel are crucial. The existing preoperative measuring methods mainly rely on 2-dimensional (2D) x-ray images or MRI cross-sections. Because the bony structure and the trajectory are 3-dimensional (3D), the relationship between the anatomical lumbar structure and the working channel cannot be precisely evaluated. Objectives: To investigate a 3D method and quantitatively evaluate the trajectory for percutaneous endoscopic lumbar discectomy (PELD). Study Design: Technical note. Setting: Pain medicine center of a university hospital. Methods: Twenty patients suffering from L4/5 disc herniation were enrolled in this study. After reconstructing the preoperative CT images, the virtual trajectory was placed into the intervertebral foramen through gradient-changing angulations in relation to the coronal and transverse planes. The overlapping portion of the virtual trajectory and the lumbar vertebrae was evaluated. In addition, the probability of atypical structure involvement was calculated. Results: As cephalad angulation (CA) increased, the intersection volume of the L4 inferior articular process increased, while the total intersection volume, the intersection volume of the L5 superior articular process, the intersection volume of the facet joint, and the volume proportion of L5 superior articular process intersection in the facet joint all decreased. As coronal plane angulation (CPA) increased, the total intersection volume, the intersection volume of the L4 inferior articular process, and the intersection volume of the facet joint all increased, while the volume proportion of the L5 superior articular process intersection in the facet joint decreased. When CA increased to 15°-20°, there was a high probability of atypical structure involvement, whereas such a probability in the groups of CA 0° (CPA 15°, 20°, and 25°), CA 5° and CA 10° was low. Limitations: Only patients with L4/5 herniation were evaluated in this study. Conclusions: In terms of the regularity, the ideal angulation for L4/L5 PELD is CPA 5°-10° and CA 5°-10°, which can lead to a relatively low level of total damage to the bony structure, minimal damage to the facet joint, and negligible involvement of atypical structures.

Abstract Background Although percutaneous endoscopic lumbar discectomy (PELD) is increasingly being used to treat lumbar degenerative disease, the treatment of elderly patients with lumbar spinal stenosis (LSS) involves considerable uncertainty. The purpose of this study was to evaluate the safety and effectiveness of PELD for the treatment of LSS in elderly patients aged 65 years or older. Methods In this retrospective review, 136 patients aged 65 years or older who underwent PELD to treat LSS were evaluated. The patients were divided into two groups, group A (ages 65–74) and group B (age ≥ 75), and perioperative data were analyzed. The Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, and MacNab classification were used to evaluate postoperative clinical efficacy. Results All patients successfully underwent the operation with satisfactory treatment outcomes. Compared to preoperative scores, the self-reported scores or pain while performing daily activities were significantly improved in both treatment groups (P < 0.05). No statistically significant between-group differences were observed in operation time, intraoperative blood loss, postoperative bed rest, and postoperative hospital stay (P > 0.05). The overall postoperative complication rate was similar between the two groups. Moreover, no statistically significant differences in VAS-back pain scores, VAS-leg pain scores, JOA scores, and MacNab classification were found between the groups at the 3-month and 1.5-year follow-up examinations (P > 0.05). Conclusion PELD is safe and effective for the treatment of LSS in elderly patients. Age is not a contraindication for decompressive lumbar spine surgery. PELD has advantages such as reduced trauma, fewer anesthesia-related complications, and a fast postoperative recovery. Elderly patients should be considered good candidates for lumbar decompression surgery using minimally invasive techniques.
