Cervical disk arthroplasty (CDA) is well-studied for 1-level and 2-level cervical pathology. There is an increasing trend towards its utilization for greater than 2-level disease as an alternative to the gold standard, anterior cervical discectomy and fusion (ACDF). The number of high-level, prospective studies or randomized trials regarding multilevel CDA is limited but continues to grow as the procedure gains popularity. In appropriately indicated patients with multilevel disease caused by disk herniations or spondylosis without extensive facet arthropathy, CDA shows promising results. Multilevel CDA should be avoided in patients with prior spinal trauma, significant degenerative spondylolisthesis with translation, arthrodesis without mobility, severely incompetent facet joints, ossification of the posterior longitudinal ligament, or kyphotic deformity. With overall similar risk profiles to ACDF but lower theoretical rates of pseudarthrosis and adjacent segment disease, multilevel CDA has been shown to preserve, or perhaps even increase, preoperative cervical range of motion. There are negligible differences in postoperative neck and arm pain, VAS scores, modified Japanese Orthopaedic Association scores, and Neck Disability Index scores when comparing multilevel CDA and ACDF. Despite current indications for multilevel CDA largely being based on single and 2-level data, careful patient selection is critical. Expansion of indications can be expected as literature continues to emerge regarding outcomes and complications in multilevel CDA, as well as with improvements in prosthesis design.

Comparison of Full Endoscopic Lumbar Diskectomy Using the Transforaminal Approach versus Interlaminar Approach for L5-S1 Lumbar Disk Herniation Treatment: A Meta-Analysis.
BACKGROUND
Numerous studies have examined the clinical effectiveness of transforaminal full endoscopic lumbar diskectomy (T-FELD) and interlaminar full endoscopic lumbar diskectomy (I-FELD) for L5-S1 lumbar disk herniation (LDH), with mixed findings. The goal of this systematic review and meta-analysis was to evaluate the perioperative outcomes, clinical results, and complications of T-FELD and I-FELD to determine their efficacy and safety for treating L5-S1 LDH and to examine the features of complications in depth.
METHODS
Several databases were searched for articles that matched all of the inclusion criteria. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were used to assess the clinical results. Information on perioperative outcomes and complications was gathered and analyzed.
RESULTS
Eight studies with 756 participants were included. There were no significant differences in postoperative bed time ( = 0.44) and hospitalization time ( = 0.49) between T-FELD and I-FELD. When compared with I-FELD, T-FELD was associated with substantially longer fluoroscopy time ( < 0.0001) and operating time ( < 0.0001). There were no significant differences in the preoperative and postoperative VAS and ODI scores between T-FELD and I-FELD. The rates for overall complications, postoperative dysesthesia, postoperative lower extremity pain, incomplete decompression, recurrence, and conversion to open surgery were comparable for T-FLED and I-FELD.
CONCLUSION
T-FELD and I-FELD had equal clinical results and safety for treatment of L5-S1 LDH. Fluoroscopy and operative times were shorter for I-FELD than for T-FELD.

OBJECTIVE
The goal of this study is to discuss our initial experience with a multimodal opioid-sparing cocktail containing ropivacaine, epinephrine, clonidine, and ketorolac (RECK) in the postoperative management of lumbar decompression surgeries.
METHODS
Patients were either administered no local anesthetic at the incision site or were administered a weight-based amount of RECK into the paraspinal musculature and subdermal space surrounding the operative site once the fascia was closed. We performed a retrospective chart review of all patients 18 years of age or older undergoing lumbar laminectomy and lumbar diskectomy surgeries between December 2019 and April 2021. Outcomes including total opioid use, measured as morphine milligram equivalent, length of stay, and postoperative visual analog scores for pain, were collected. Relationships between variables were analyzed with Student's t-test, chi-square tests, and Fisher exact tests.
RESULTS
A total of 121 patients undergoing 52 lumbar laminectomy and 69 lumbar diskectomy surgeries were identified. For lumbar laminectomy, patients who were administered RECK had decreased opioid use in the postoperative period (11.47 ± 12.32 vs. 78.51 ± 106.10 morphine milligram equivalents, P = 0.019). For patients undergoing lumbar diskectomies, RECK administration led to a shorter length of stay (0.17 ± 0.51 vs. 0.79 ± 1.45 days, P = 0.019) and a lower 2-hour postoperative pain score (3.69 ± 2.56 vs. 5.41 ± 2.28, P = 0.006).
CONCLUSIONS
The RECK cocktail has potential to be an effective therapeutic option for the postoperative management of lumbar decompression surgeries.

This study aims to compare the outcomes of interlaminar and transforaminal approaches for full-endoscopic discectomy (FED) for treating L4/5 lumbar disc herniation (LDH).A retrospective study of patients with L4/5 LDH treated with interlaminar endoscopic lumbar discectomy (IELD, n = 19) or transforaminal endoscopic lumbar discectomy (TELD, n = 105) was conducted. Patient background, radiological findings, and operative data were collected. Oswestry Disability Index (ODI) and European Quality of Life-5 Dimension (EQ-5D) scores were recorded preoperatively and 1 and 2 years postoperatively.Although ODI and EQ-5D scores 1 and 2 years postoperatively improved statistically in the IELD and TELD groups, there were no statistical differences between the groups. IELD was predominantly performed in patients who were taller and heavier. The mean operative times and the frequency of laminectomy for IELD and TELD were 67.2 and 44.6 min and 63.2 and 17.1%, respectively (P < 0.001). The radiological findings showed that the concave configuration of the L4 lamina, interlaminar space width, and foraminal width were statistically different between the groups. There were no complications in either of the groups. Reoperation was required for recurrence in two and five patients in the IELD and TELD groups (P = 0.29), respectively.Operative outcomes were identical between the two groups. Although the operative time was longer in the IELD group, both approaches were safely and effectively performed. Depending on the patient's physique and preoperative radiological findings, the more suitable approach for L4/5 LDH should be chosen.

BACKGROUND CONTEXT
Anterior cervical discectomy and fusion (ACDF) is the leading surgical treatment for cervical radiculopathy. However, ACDF surgery has been suggested for to accelerate the degeneration of the adjacent cervical discs, which causes so-called adjacent segment disease (ASD). Over the past 2 decades, total disc replacement (TDR)/cervical disc arthroplasty (CDA) has become an increasingly common method for treating degenerative cervical diseases. The rationale is that a synthetic disc prosthesis may preserve motion at the operated level, which is expected to lead to reduced stress on the other cervical levels and thus decrease the risk of developing ASD. However, since the method was first introduced in the early 2000s, the long-term outcome after it is still not completely understood.
PURPOSE
Our goal was to compare the long-term outcomes of TDR and ACDF procedures.
STUDY DESIGN
Retrospective case-control study.
PATIENT SAMPLE
All patients who underwent TDR due to degenerative cervical disease at Helsinki University Hospital between 2006 and 2012 (38 patients) and matched control patients who underwent ACDF during this period (76 patients) for degenerative disc disease.
OUTCOME MEASURES
The primary outcome measure was the rate of reoperations and further cervical surgeries. Secondary outcome measures included neck symptoms (Neck Disability Index, or NDI), health-related quality of life (EQ-5D-3L), satisfaction with the surgery, radiological outcomes, and employment status.
METHODS
The medical records of all patients who underwent TDR due to degenerative cervical disease at Helsinki University Hospital between 2006 and 2012 and those of the matched control patients were analyzed retrospectively. Questionnaires were sent to all available patients at the end of the follow-up (median 14 years) to evaluate their employment status, levels of satisfaction with the surgery, current neck symptoms, and health-related quality of life. Radiological outcomes were evaluated from the cervical plain radiographs, which were taken either at the end of the follow-up as a part of the present study or earlier on for other clinical reasons, but at least 2 years after index surgery.
RESULTS
The total rate of reoperations and further cervical surgeries during the follow-up of a median of 14 years was 7/38 (18%) in the TDR group and 6/76 (8%) in the ACDF group (p=.096, ns.). Total disc replacement patients were reoperated earlier, and the 5-year reoperation rate was significantly higher in the TDR group (11% vs 1.3%, p=.026). None of the TDR patients underwent further cervical surgery more than 6 years after index surgery, whereas 5/6 (83%) of the reoperated ACDF patients were reoperated after that time. There were no significant differences in the NDIs between the patient groups. The employment rate and health-related quality of life were slightly higher in the TDR group, but the differences were statistically nonsignificant. TDR was significantly better at maintaining the angular range of motion at the operated level, and the fusion rate was significantly lower among this group.
CONCLUSIONS
There were no significant differences in the long-term outcomes of ACDF and TDR when measured by reoperation rates, employment status, NDI, EuroQoL, and satisfaction with surgery. Reoperation rate and, on the other hand, employment rate and health-related quality of life, were higher in the TDR group, but the differences were statistically nonsignificant. However, TDR patients were reoperated earlier, and the 5-year reoperation rate was significantly higher in the TDR group. Randomized long-term studies in which these methods are compared are needed to further clarify the differences between them.

OBJECTIVE
To identify the incidence and predictors of postoperative dysphagia in patients who undergo anterior cervical spine surgery (ACSS) by utilizing the Eating Assessment Tool (EAT-10).
METHODS
A multicenter prospective study was undertaken at three hospitals to evaluate patients undergoing ACSS between January 2021 and January 2023. Included patients were aged 18-80 years and were undergoing primary or revision ACSS. Dysphagia was assessed using the validated EAT-10 questionnaire. Patients with dysphagia were included in the observation group, and those without dysphagia were included in the control group.
RESULTS
Of the 343 patients enrolled, 50 patients (14.6%) had EAT-10 scores of 3 or more at the 6-month follow-up. In the univariate analysis, patients with dysphagia at 7 days had a longer operative time, were current smokers, had involvement of vertebral bodies at C4 and above, and underwent intraoperative neurophysiological monitoring. Patients with dysphagia at 6 months had involvement of vertebral bodies at C4 and above and underwent intraoperative neurophysiological monitoring. In the multivariate analysis to determine associations with prolonged dysphagia, only the involvement of vertebral bodies at C4 and above (odds ratio 3.883, 95% confidence interval 1.847-8.165, P = 0.001) and intraoperative neurophysiological monitoring (odds ratio 0.273, 95% confidence interval 0.080-0.931, P = 0.038) remained significant.
CONCLUSIONS
Dysphagia is common after ACSS, affecting more than 67.5% of patients at 7 days postoperatively, but over time, the incidence of dysphagia gradually decreases. Involvement of the vertebral bodies at C4 and above is a risk factor for dysphagia after ACSS, and intraoperative neurophysiological monitoring is a protective factor.

Spine Sep 2023Retrospective cohort study.
Improving Racial and Ethnic Disparities in Outpatient Anterior Cervical Discectomy and Fusion Driven by Increasing Utilization of Ambulatory Surgical Centers in New York State.
STUDY DESIGN
Retrospective cohort study.
OBJECTIVE
The purpose of this study was to assess trends in disparities in utilization of hospital outpatient departments (HOPDs) and ambulatory surgical centers (ASCs) for outpatient ACDF (OP-ACDF) between White, Black, Hispanic, and Asian/Pacific Islander patients from 2015 to 2018 in New York State.
SUMMARY OF BACKGROUND DATA
Racial and ethnic disparities within the field of spine surgery have been thoroughly documented. To date, it remains unknown how these disparities have evolved in the outpatient setting alongside the rapid emergence of ASCs and whether restrictive patterns of access to these outpatient centers exist by race and ethnicity.
MATERIALS AND METHODS
We conducted a retrospective review from 2015 to 2018 using the Healthcare Cost and Utilization Project (HCUP) New York State Ambulatory Database. Differences in utilization rates for OP-ACDF were assessed and trended over time by race and ethnicity for both HOPDs and freestanding ASCs. Poisson regression was used to evaluate the association between utilization rates for OP-ACDF and race/ethnicity.
RESULTS
Between 2015 and 2018, Black, Hispanic, and Asian patients were less likely to undergo OP-ACDF compared with White patients in New York State. However, the magnitude of these disparities lessened over time, as Black, Hispanic, and Asian patients had greater relative increases in utilization of HOPDs and ASCs for ACDF when compared with White patients ( Ptrend <0.001). The magnitude of the increase in freestanding ASC utilization was such that minority patients had higher ACDF utilization rates in freestanding ASCs by 2018 ( P <0.001).
CONCLUSIONS
We found evidence of improving racial disparities in the relative utilization of outpatient ACDF in New York State. The increase in access to outpatient ACDF appeared to be driven by an increasing number of patients undergoing ACDF in freestanding ASCs in large metropolitan areas. These improving disparities are encouraging and contrast previously documented inequalities in inpatient spine surgery.

BACKGROUND
Annulus fibrosis (AF) defects have been identified as the primary cause of disc herniation relapse and subsequent disc degeneration following discectomy. Stem cell-based tissue engineering offers a promising approach for structural repair. Menstrual blood-derived mesenchymal stem cells (MenSCs), a type of adult stem cell, have gained attention as an appealing source for clinical applications due to their potential for structure regeneration, with ease of acquisition and regardless of ethical issues.
METHODS
The differential potential of MenSCs cocultured with AF cells was examined by the expression of collagen I, SCX, and CD146 using immunofluorescence. Western blot and ELISA were used to examine the expression of TGF-β and IGF-I in coculture system. An AF defect animal model was established in tail disc of Sprague-Dawley rats (males, 8 weeks old). An injectable gel containing MenSCs (about 1*10/ml) was fabricated and transplanted into the AF defects immediately after the animal model establishment, to evaluate its repairment properties. Disc degeneration was assessed via magnetic resonance (MR) imaging and histological staining. Immunohistochemical analysis was performed to assess the expression of aggrecan, MMP13, TGF-β and IGF-I in discs with different treatments. Apoptosis in the discs was evaluated using TUNEL, caspase3, and caspase 8 immunofluorescence staining.
RESULTS
Coculturing MenSCs with AF cells demonstrated ability to express collagen I and biomarkers of AF cells. Moreover, the coculture system presented upregulation of the growth factors TGF-β and IGF-I. After 12 weeks, discs treated with MenSCs gel exhibited significantly lower Pffirrmann scores (2.29 ± 0.18), compared to discs treated with MenSCs (3.43 ± 0.37, p < 0.05) or gel (3.71 ± 0.29, p < 0.01) alone. There is significant higher MR index in disc treated with MenSCs gel than that treated with MenSCs (0.51 ± 0.05 vs. 0.24 ± 0.04, p < 0.01) or gel (0.51 ± 0.05 vs. 0.26 ± 0.06, p < 0.01) alone. Additionally, MenSCs gel demonstrated preservation of the structure of degenerated discs, as indicated by histological scoring (5.43 ± 0.43 vs. 9.71 ± 1.04 in MenSCs group and 10.86 ± 0.63 in gel group, both p < 0.01), increased aggrecan expression, and decreased MMP13 expression in vivo. Furthermore, the percentage of TUNEL and caspase 3-positive cells in the disc treated with MenSCs Gel was significantly lower than those treated with gel alone and MenSCs alone. The expression of TGF-β and IGF-I was higher in discs treated with MenSCs gel or MenSCs alone than in those treated with gel alone.
CONCLUSION
MenSCs embedded in collagen I gel has the potential to preserve the disc structure and prevent disc degeneration after discectomy, which was probably attributed to the paracrine of growth factors of MenSCs.

Review
PURPOSE
Hirayama disease, a rare cervical myelopathy in children and young adults, leads to progressive upper limb weakness and muscle loss. Non-invasive external cervical orthosis has been shown to prevent further neurologic decline; however, this treatment modality has not been successful at restoring neurologic and motor function, especially in long standing cases with significant weakness. The pathophysiology remains not entirely understood, complicating standardized operative guidelines; however, some studies report favorable outcomes with internal fixation. We report a successful surgically treated case of pediatric Hirayama disease, supplemented by a systematic review and collation of reported cases in the literature.
METHODS
A review of the literature was performed by searching PubMed, Embase, and Web of Science. Full-length articles were included if they reported clinical data regarding the treatment of at least one patient with Hirayama disease and the neurologic outcome of that treatment. Articles were excluded if they did not provide information on treatment outcomes, were abstract-only publications, or were published in languages other than English.
RESULTS
Of the fifteen articles reviewed, 63 patients were described, with 59 undergoing surgery. This encompassed both anterior and posterior spinal procedures and 1 hand tendon transfer. Fifty-five patients, including one from our institution, showed improvement post-treatment. Eleven of these patients were under 18 years old.
CONCLUSION
Hirayama disease is an infrequent yet impactful cervical myelopathy with limited high-quality evidence available for optimal treatment. The current literature supports surgical decompression and stabilization as promising interventions. However, comprehensive research is crucial for evolving diagnosis and treatment paradigms.

OBJECTIVE
To investigate the effects of two types of temperature rinses on body temperature, inflammatory cytokine levels, and bleeding volume in percutaneous endoscopic lumbar discectomy.
METHODS
Eighty patients underwent percutaneous endoscopic lumbar discectomy from January 2018 to December 2020 were selected and divided into experimental group (40 cases) and control group(40 cases). In experimental group, there were 19 males and 21 females, aged (38.8±9.8) years old;7patients on L and 33 patients on LS;Body msss index(BMI) was (27.8±7.2) kg·m. In contral group, there were 18 males and 22 females, aged (41.5±10.9) years old, 5 patients on L and 35 patients on LS;BMI was (26.4±6.2) kg·m. The patients in the control group were received normal saline rinse at room temperature, and the patients in the experimental group were received normal saline rinse heated to 37 ℃. Body temperature, chills, nausea, vomiting, and other adverse reactions were recorded. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-10 (IL-10) in two groups were recorded before and 2 hours after operation. Visual analogue scale (VAS) was used to evaluate the degree of lumbar pain in two groups before and 2 hours after surgery. Fibrinolytic-coagulation indexes with preoperative and 2 hours after surgery, including the D-dimer (DD), fibrinogen degradation products (FDP), activated partial thrombin time (APTT) and prothrombin time (PT) were recorder. Operation time and blood loss in two groups were recorded.
RESULTS
The body temperature of both groups showed a downward trend, while the body temperature of the control group was lower than that of the experimental group. The levels of TNF-α, IL-6 and IL-10 in two groups were increased 2 hours after surgery compared with those before surgery(<0.05), while the levels in experimental group were lower than those in control group(<0.05). Postoperative VAS in experimental group 2.19±1.13 was significantly lower than that in the control group 3.38±1.35(<0.05). The levels of DD and FDP at 2 hours after surgery in both groups were higher than those before surgery (<0.05), while the levels of DD and FDP in the experimental group were higher than those in the control group (<0.05). There was no significant difference in APTT and PT levels between two groups after operation (>0.05). The blood loss in the experimental group of (45.2±14.1) ml was lower than that in the control group of (59.52±15.6) ml. The operation time of experimental group (46.7±13.8) min was less than that of control group (58.3±15.2) min(<0.05).
CONCLUSION
Body temperature rinse can reduce the incidence of adverse reactions, alleviate local inflammatory reactions, reduce intraoperative blood loss and shorten the operation time.
