Objective. To compare the effectiveness of surgical methods for treating patients with recurrent lumbar disc herniation.Material and Methods. The sample consisted of 160 patients operated on in 2014–2019 for recurrent lumbar disc herniation by percutaneous endoscopic discectomy (Group 1), microsurgical discectomy (Group 2), single-level transforaminal interbody fusion (Group 3) and single-level total intervertebral disc replacement (Group 4). The effectiveness of surgical treatment was evaluated using the NRS-11, ODI, and MacNab questionnaires.Results. Assessment of the pain syndrome severity and the vital activity level of patients revealed significant (p < 0.05) differences in favor of total intervertebral disc replacement. Excellent and good outcomes after arthroplasty according to MacNab criteria were noted in all patients in this group. Similar outcomes were reported in 77.5 % (31/40) of patients in the TLIF group, in 75.1 % (24/32) of patients in the percutaneous endoscopic discectomy group and in 72.6 % (45/62) of patients in the microdiscectomy group. The operation time and length of hospital stay were shorter in the endoscopic and microsurgical discectomy groups (p < 0.001). However, the lower incidence of complications and reoperations was observed in groups of posterior interbody fusion and arthroplasty (p > 0.05).Conclusion. Arthroplasty with the M6-L implant expands the possibilities of surgery for recurrent lumbar disc herniation. Total intervertebral disc replacement and posterior interbody fusion for recurrent lumbar disc herniation are more effective in comparison with decompressive operations, which is reflected in the improvement of clinical treatment outcomes, reduction of perioperative complications and frequency of repeated interventions.

Lumbar intervertebral disc protrusion disease refers to the degeneration of intervertebral disc, rupture of fibrous ring, nucleus pulpous protrusion and stimulation or compression of nerve root. The import command in Mimics medical 3D reconstruction software was used to erase the irrelevant image data and obtain vertebral body images. The original 3D model of each vertebral body was built by 3D computing function. A three-dimensional finite element model was established to analyze the effect of different surgical methods on the mechanical distribution of the spine after disentomb. The stress distribution of the spine, intervertebral disc, and left and right articular cartilage at L4/L5 stage and the position shift of the fourth lumbar vertebra were analyzed under 7 working conditions of vertical, forward flexion, extension, left and right flexion, and left and right rotation. The results showed that the established model was effective, and the smaller the area of posterior laminar decompression was, the lesser the impact on spinal stability was. The PELD treatment of lumbar disc herniation had little impact on spinal biomechanics and could achieve good long-term biomechanical stability. Combining the clinical experiment method and finite element simulation, using the advantages of finite element software to optimize the design function can provide guidance for the design and improvement of medical devices and has important significance for the study of clinical mechanical properties and biomechanics.

Objective. Recurrent lumbar disc herniation (RLDH) is the most common cause of sciatica after primary discectomy. The purpose of this study was to evaluate the efficacy of transpedicular dynamic stabilization (TDS) combined with limited rediscectomy in the treatment of single-level RLDH. Methods. We retrospectively evaluated a consecutive series of 24 middle-aged patients who underwent TDS (Dynesys system) combined with limited rediscectomy (i.e., removing only extruded or loose disc fragments) for single-level Carragee type II and type IV RLDH between April 2012 and September 2017. Clinical results were evaluated with visual analog scale (VAS) for leg and low back pain, Oswestry Disability Index (ODI) scores, and complications. Imaging data include lumbar segment motion and intervertebral height. Results. The mean follow-up period was 38 months. The VAS and ODI scores were significantly improved at the last follow-up. The average range of motion (ROM) at the stabilized segment was 6.4° before surgery and 4.2° at the last follow-up, with a 78.6% mean preservation ( P  < 0.05). Intervertebral height at the stabilized segment decreased slightly after surgery ( P  < 0.05). However, there was no further decline at the last follow-up. There were no cases of reherniation, screw loosening, or segmental instability. Conclusions. TDS combined with limited rediscectomy resulted in an effective procedure in middle-aged patients with Carragee type II and type IV RLDH. It was able to stabilize the operated segment with partial motion preservation. Moreover, it could maintain disc height and decrease the risk of recurrence in patients with a large posterior annular defect.

Abstract OBJECTIVE Same-level recurrent lumbar disc herniation complicates outcomes after primary discectomy in a subset of patients. The health care costs associated with the management of this complication are currently unknown. We set out to identify the incidence and health care cost of same-level recurrent disc herniation after single-level lumbar discectomy at our institution. METHODS We retrospectively reviewed 156 consecutive patients undergoing primary single-level lumbar discectomy at one institution. The incidence of symptomatic same-level recurrent disc herniation either responding to conservative therapy or requiring revision discectomy was assessed. Institutional billing and accounting records were reviewed to determine the billing costs of all diagnostic and therapeutic measures used for patients experiencing recurrent disc herniation. RESULTS Twelve months after surgery, 141 patients were available for follow-up. Of these patients, 124 (88%) were symptom free or had minimal symptoms not affecting their daily activity. Radiographically proven symptomatic same-level recurrent disc herniation developed in 17 patients (12%) a median of 8 months after primary discectomy. Eleven patients (7%) required revision surgery, whereas 6 (3.9%) responded to conservative therapy alone. Diagnosis and management of recurrent disc herniation were associated with a mean cost of $26 593 per patient, and the mean cost was markedly less for patients responding to conservative treatment ($2315) compared with those requiring revision surgery ($39 836) (P &lt; 0.001). Of 141 primary lumbar discectomies performed at our institution with the patients followed for 1 year, the total cost associated with the management of subsequent recurrent disc herniation was $452 083 ($289 797 per 100 primary discectomies). CONCLUSION In our experience, recurrent lumbar disc herniation occurred in more than 10% of patients and was associated with substantial health care costs. Development of novel techniques to prevent recurrent lumbar disc herniation is warranted to decrease the health care costs and morbidity associated with this complication. Prolonged conservative management should be attempted when possible to reduce the health care costs of this complication.
