The problem of patients\' rehabilitation after spinal surgery remains relevant. The use of therapeutic physical factors, both preformed and natural, including pelotherapy, is very important. The application of the latter requires to develop new techniques in this pathology, one of which is low temperature exposure.
OBJECTIVE: To study the possibility and to assess the effectiveness of resource-saving nonthermal pelotherapy techniques in patients\' rehabilitation, who underwent surgeries for intervertebral discs\' herniation.
METHODS: The number of patients equal 88, including 39 males and 49 females, after lumbar microdiscectomy, was examined in this study. The patients were divided into 3 groups. Control group (28 patients) received a basic rehabilitation complex (therapeutic gymnastics, massage, low-frequency magnetotherapy); the 1st study group (30 patients) - basic complex and procedures of thin layer applications with peat muds preparation (Tomed-applikat) at 20-24 °C; the 2nd study group (30 patients) - basic complex and procedures of fluctuoresis of 2% solution of peat mud Tomed-aqua preparation.
RESULTS: There was a significant reduction of pain syndrome, recovery of sensitivity and motor activity, decrease of Oswestry index, characterizing the degree of vital activity disturbance, in patients of the study group compared to the control group after treatment.
CONCLUSIONS: The inclusion of nonthermal resource-saving techniques of pelotherapy in rehabilitation complex of patients who underwent spinal surgery is effective and pathogenetically justified.
Проблема реабилитации больных после перенесенных оперативных вмешательств на позвоночнике остается актуальной. При этом большое значение имеет применение лечебных физических факторов как преформированных, так и природных, в том числе пелоидотерапии. Использование последней нуждается в разработке новых методик при этой патологии, одной из которых является низкотемпературное воздействие.

Dysphagia after anterior cervical spine surgery has a 5% to 15% incidence beyond 1-year postsurgery, often attributed to mechanical factors such as pharyngeal thickening and epiglottis inversion. Despite normal neurological examination and electromyography, nerve distortion related to stretching also remains a possibility in these patients and may cause allodynia resulting in odynophagia and dysphagia. Current treatment options for dysphagia after anterior cervical discectomy and fusion are limited to local intraoperative steroid injections and tracheal traction exercises. In our patient, a glossopharyngeal nerve block was effectively used to manage the glossopharyngeal allodynia, thereby reducing the odynophagia and dysphagia, ultimately enhancing oral tolerance.

METHODS: A technical note and retrospective case series.
OBJECTIVE: Highly upward-migrated lumbar disc herniation (LDH) is challenging due to its problematic access and incomplete removal. The most used interlaminar approach may cause extensive bony destruction. We developed a novel translaminar approach using the unilateral portal endoscopic (UBE) technique, emphasizing effective neural decompression, and preserving the facet joint\'s integrity.
METHODS: This retrospective study included six patients receiving UBE translaminar discectomy for highly upward-migrated LDHs from May 2019 to June 2021. The migrated disc was removed through a small keyhole on the lamina of the cranial vertebra. The treatment results were evaluated by operation time, hospital stays, complications, visual analog scale (VAS), Oswestry Disability Index (ODI), Japanese Orthopaedic Association (JOA) score, and modified MacNab criteria.
RESULTS: The mean pre-operative VAS for back pain (5.0 ± 4.9), VAS for leg pain (9.2 ± 1.0), JOA score (10.7 ± 6.6), and ODI (75.7 ± 25.3) were significantly improved to 0.3 ± 0.5, 1.2 ± 1.5, 27.3 ± 1.8, 5.0 ± 11.3 respectively at the final follow-up. Five patients had excellent, and one patient had good outcomes according to the Modified MacNab criteria. The hospital stay was 2.7 ± 0.5 days. No complication was recorded. The MRI follow-up showed complete disc removal, except for one patient with an asymptomatic residual disc.
CONCLUSIONS: UBE translaminar discectomy is a safe and effective minimally invasive procedure for highly upward-migrated LDH with satisfactory treatment outcomes and nearly 100% facet joint preservation.

To compare the clinical efficacy of interlaminar endoscopic surgical system delta (iLESSYS-Delta) discectomy with that of classical fenestration discectomy for treating lumbar disc herniation. Patients who underwent iLESSYS-Delta or fenestration discectomy were enrolled in this study. Baseline information and clinical indicators were collected. The baseline data were matched using propensity score matching. Fifty-two patients were in each group. In the iLESSYS-Delta cohort, the volume of intraoperative bleeding was 18.17 ± 4.20 ml, the length of postoperative hospital stay was 4.16 ± 2.29 days, and the length of postoperative off-bed activity was 1.58 ± 0.88 days. In contrast, in the fenestration group, the volume of intraoperative bleeding was 32.50 ± 17.13 ml, the length of postoperative hospital stay was 6.66 ± 2.44 days, and the length of postoperative off-bed activity was 3.18 ± 1.28 days. The difference between the two groups was statistically significant (P < 0.05). The operation time was 88.90 ± 19.14 min in the iLESSYS-Delta group and 67.63 ± 19.32 min in the fenestration group, and the difference between the two groups was statistically significant (P < 0.05). Regarding the pain visual analogue scale scores at 24, 48, and 72 h after surgery, patients in the iLESSYS-Delta group had less pain than did those in the fenestration group (P < 0.05). The Oswestry disability indices of postoperative patients in both groups significantly improved at 3 months after surgery and at the last follow-up (P < 0.05); however, there was no statistically significant difference in the postoperative ODI scores between the two surgery groups (P > 0.05). The two groups showed no significant differences in clinical effects, postoperative recurrence rates, or perioperative complications. iLESSYS-Delta can cause less intraoperative bleeding and faster recovery than fenestration discectomy.

METHODS: A 51-year-old woman, who had previously undergone C5-C7 anterior cervical discectomy and fusion, presented with symptomatic hardware failure and subsequently underwent instrumentation removal. Her postoperative course was complicated by an esophageal perforation. Despite initial repair using a rotational flap, the leak persisted, prompting esophageal reconstruction with a radial forearm free flap (RFFF).
CONCLUSIONS: Persistent esophageal perforation is exceedingly rare and difficult to treat. This report discusses the surgical technique for RFFF, an excellent option for revising failed sternocleidomastoid rotational flaps. The decision between rotational repair and free flap reconstruction depends on factors such as defect size, vascularization, wound condition, and donor site morbidity.

OBJECTIVE: The study aims to explore the management of two-level cervical disc disease and to compare outcomes of anterior cervical discectomy and fusion (ACDF), cervical disc arthroplasty (CDA), and hybrid surgery (HS).
METHODS: Between December 2011 and December 2021, a total of 120 patients (76 males, 44 females; mean age: 44.8±8.1 years; range, 18 to 68 years) who were diagnosed as two-level cervical disc disease and underwent anterior cervical surgery were retrospectively analyzed. The patients were randomly divided into three groups as ACDF, CDA, and HS each consisting of 40 patients. The Neck Disability Index (NDI), Visual Analog Scale (VAS), clinical and radiological findings, and range of motion (ROM) data were evaluated.
RESULTS: All of the groups showed a significant improvement according to clinical and radiological outcomes (p=0.01). The mean follow-up was 27.5±6.1 months for ACDF, 20.0±4.7 months for CDA, and 21.1±5.0 months for HS, showing consistency in monitoring post-surgery outcomes. The mean postoperative NDI scores were 13.4±5.6, 14.8±5.2 and 15.0±5.5 in the ACDF, CDA and HS groups, respectively (p=0.056). The mean postoperative ROM values were 20.82±5.66, 32.45±11.21 and 27.18±10.89, respectively (p=0.045).
CONCLUSIONS: All three surgical techniques, ACDF, CDA, and HS, are safe and successful in the treatment of two-level cervical disc disease. However, HS and CDA may be more preferable over ACDF attributed to their motion-preserving benefits and effectively combining fusion and motion preservation techniques, with comparable clinical and radiological outcomes.

BACKGROUND: Non-contiguous two-level Anterior Cervical Discectomy and Fusion (ACDF) may be a viable option for patients with degenerative cervical myelopathy and imaging-evident spine and radicular compression at two non-contiguous cervical levels. The risk of hastening degeneration and triggering Adjacent Segment Disease at the spine levels located between the fused levels is a putative adverse event, which was assessed in a few studies. The aim of this study is to investigate the clinical outcomes of patients undergoing non-contiguous two levels ACDF and to assess biomechanical modifications at non-fused segments.
METHODS: We retrospectively reviewed all patients with noncontiguous two-level spine and radicular compression, who underwent simultaneous noncontiguous two-level ACDF at our center. We analyzed clinical and radiological outcomes and investigated the rate of adjacent segment disease. Radiographic parameters were calculated on pre- and postoperative images.
RESULTS: Thirty-two patients underwent simultaneous noncontiguous two-level ACDF for cervical myelo-radiculopathy between 2015 and 2021 and were followed up for a mean period of 43.3 months. For all patients, the mJOA score significantly improved from 14.57 ± 2.3 to 16.5 ± 2.1 (p<0.01) and the NDI score significantly decreased from 21.45 ± 4.3 to 12.8 ± 2.3 (p<0.01) postoperatively. Cervical lordosis increased after surgery (from 9.65° ±9.47 to 15.12° ± 6.09); intermediate disc height decreased (5.68 mm ± 0.57 to 5.27 mm ±0.98); the ROMs of intermediate (from 12.45 ± 2.33 to 14.77 ± 1.98), cranial (from 14.63 ± 1.59 to 15.71 ± 1.02), and caudal (from 11.58 ± 2.32 to 13.33 ± 2.67) segments slightly increased. During follow-up assessment, in one patient the myelopathy worsened due to spine compression at the intermediate level.
CONCLUSIONS: Simultaneous and non-contiguous two-level ACDF is a safe and effective procedure. The occurrence of postoperative adjacent and intermediate segment disease is rare.

According to the literature, recurrent disc herniation of the lumbar spine occurs in 5-10% of cases. Objective. To develop an algorithm for surgical treatment of recurrent lumbar spine disc herniation based on analysis of risk factors of relapse and assessment of intra- and postoperative period.
METHODS: The study included 61 patients with recurrent intervertebral disc herniation. Thirty patients underwent repeated microdiscectomy without transpedicular fixation, 31 patients - resection of recurrent disc herniation with transpedicular fixation (PLIF technique). The control group included 63 patients without recurrent disc herniation. Mean follow-up period was 3.5 years.
RESULTS: Discectomy with transpedicular fixation is characterized by larger extent, prolonged surgery time and rehabilitation period. However, there is lower risk of recurrent disc herniation and CSF leakage. Repeated microdisectomy without transpedicular fixation is characterized by smaller extent and shorter surgery time, as well as faster recovery period. Nevertheless, we have higher risk of recurrent disc herniation and CSF leakage. We developed a method for assessing the probability of recurrent intervertebral disc herniation. This algorithm allows us to predict the probability of recurrent disc herniation in a particular patient with 86.7% accuracy.
CONCLUSIONS: We proposed an algorithm for choosing surgical treatment of recurrent disc herniation. Microdiscectomy without fixation is advisable for the risk of recurrent disc herniation <30%, discectomy with transpedicular fixation - for risk of disc herniation >30%.

UNASSIGNED: На основании данного метода предложен алгоритм выбора тактики хирургического лечения рецидивов грыж диска: при вероятности развития рецидива грыжи диска <30% рекомендовано использование микродискэктомии без фиксации, в случае вероятности развития рецидива грыжи диска >30% предлагается выполнять дискэктомию с транспедикулярной фиксацией.

BACKGROUND: Biportal endoscopic spine surgery (BESS) has gained traction for lumbar laminectomy and diskectomy. To justify the transition to BESS, outcomes and the surgical learning curve should be known. This study evaluates rates of complications with BESS and how these rates change with increased surgeon experience.
METHODS: A single surgeon\'s consecutive patients who underwent BESS were evaluated. Patients older than 18 years who underwent BESS for lumbar laminectomy and diskectomy were included. Patients with previous spine surgery, multiple levels, or BESS for fusion were excluded. Demographics, length of surgery, intraoperative complications, postoperative complications, and revision surgery were recorded. The learning phase group and mastery phase group were based on a cumulative summation analysis based on surgical time.
RESULTS: A total of 63 patients, with 31 and 32 patients in the learning and mastery group, respectively, were included. Surgical time decreased from 87 to 52 minutes in the mastery phase. Conversion to open decreased from 3 to 0 cases (P = 0.1803), intraoperative complications decreased from 3 to 0 (P = 0.1803), postoperative complications decreased from 7 to 2 (P = 0.017), and rates of revision surgery decreased from 4 to 1 (P = 0.4233).
CONCLUSIONS: This study suggests a learning curve of 31 cases for adequate performance of BESS for lumbar laminectomy and diskectomy.

BACKGROUND: Cervical spondylosis in the warfighter is a common musculoskeletal problem and can be career-ending especially if it requires fusion. Head-mounted equipment and increased biomechanical forces on the cervical spine have resulted in accelerated cervical spine degeneration. Current surgical gold standard is anterior cervical discectomy and fusion (ACDF). Posterior cervical foraminotomy (PCF) is a nonfusion surgical alternative, and this can be effective in alleviating radiculopathy from foraminal stenosis caused by disc-osteophyte complex. Biomechanical studies have not been done to analyze motion associated with military aircrew personnel following PCF. The aim of this study was to compare the biomechanical responses of the effects of ACDF and PCF with different grades of facet resection under simulated military aircrew conditions using range of motion, disc pressure, and facet loads at the index and adjacent levels.
METHODS: A validated 3D finite element model of the human cervical spinal column was used to simulate various graded PCF and ACDF. All surgical simulations were performed at the most commonly operated level (C5-C6) in warfighters. Pure moment loading under flexion, extension, and lateral bending, and in vivo follower force of 75 N were applied to the intact spine. Hybrid loading protocol was used to achieve 134 degrees of combined flexion-extension and 83 degrees of lateral bending in intact and surgical models to reflect military loading conditions. Segmental motions, disc pressure, and facet load were obtained and normalized with respect to the intact model to quantify the biomechanical effect.
RESULTS: Anterior cervical discectomy and fusion decreased range of motion at the index and increased motion at the adjacent levels, while all graded PCF responses had an opposite trend: increased motion at the index and decreased motion at adjacent levels. The magnitude of changes depended on the level of resection, spinal level, and loading mode. Disc pressure increased at the index level and decreased at the adjacent levels after PCF. These changes were exaggerated with increasing extent of facet resection. Facet load increased at the index level after PCF especially with extension and right (contralateral) lateral bending. Complete facetectomy led to facet load increases greater than ACDF at the adjacent levels in both flexion and extension.
CONCLUSIONS: Posterior cervical foraminotomy is a motion-preserving implant-free surgical alternative to ACDF for warfighters with cervical radiculopathy after failure of conservative management. The treating surgeon must pay close attention to the extent of facet resection to avoid potential spinal instability and future disc and facet degeneration after PCF. Posterior cervical foraminotomy can be more advantageous than ACDF in terms of adjacent segment degeneration, motion preservation, reoperation rate, surgical cost, and retention of warfighters.
