RESUMEN
BACKGROUND CONTEXT: Anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) are commonly performed operations to address cervical radiculopathy and myelopathy. Trends in utilization and revision surgery rates warrant investigation. PURPOSE: To explore the epidemiology, postoperative complications, and reoperation rates of ACDF and CDA. DESIGN: Retrospective cohort study. PATIENT SAMPLE: A total of 433,660 patients who underwent ACDF or CDA between 2011 and 2021 were included in this study. OUTCOME MEASURES: The following data were observed for all cases: patient demographics, complications, and revisions. METHODS: The PearlDiver database was queried to identify patients who underwent ACDF and CDA between 2011 and 2021. Epidemiological analyses were performed to examine trends in cervical procedure utilization by age group and year. After matching by age, sex, Charlson Comorbidity Index (CCI), levels of operation, and reason for surgery, the early postoperative (2-week), short-term (2-year), and long-term (5-year) complications of both cervical procedures were examined. RESULTS: In total, 404,195 ACDF and 29,465 CDA patients were included. ACDF utilization rose by 25.25% between 2011 and 2014 while CDA utilization rose by 654.24% between 2011-2019 followed by relative plateauing in both procedures. Mann-Kendall trend test confirmed a significant but small rise in ACDF and large rise in CDA procedures from 2011 to 2021 (p<.001). After matching, ACDF and CDA had an overall complication rate of 12.20% and 8.77%, respectively, with the most common complications being subsequent anterior revision (4.96% and 3.35%) and dysphagia (3.70% and 2.98%). The ACDF cohort, especially multilevel ACDF patients, generally had more complications and higher revision rates than the CDA cohort (p<.05). CONCLUSIONS: While ACDF utilization has plateaued since 2014, CDA rates have risen by a staggering 654.24% over the past decade. ACDF and CDA complication and revision rates were relatively low in comparison to previously published values, with significantly lower rates in CDA. Although a lack of radiographic data in this study limits its power to recommend either procedure for individual patients with cervical radiculopathy or myelopathy, CDA may be associated with minor improvement in the complication and revision profile.

BACKGROUND CONTEXT: Racial disparities in spine surgery have been thoroughly documented in the inpatient (IP) setting. However, despite an increasing proportion of procedures being performed as same-day surgeries, whether similar differences have developed in the outpatient (OP) setting remains to be elucidated. PURPOSE: This study aimed to investigate racial differences in postoperative outcomes between Black and White patients following OP and IP lumbar and cervical spine surgery. STUDY DESIGN/SETTING: Retrospective cohort study. PATIENT SAMPLE: Patients who underwent IP or OP microdiscectomy, laminectomy, anterior cervical discectomy and fusion (ACDF), or cervical disc replacement (CDR) between 2017 and 2021. OUTCOME MEASURES: Thirty-day rates of serious and minor adverse events, readmission, reoperation, nonhome discharge, and mortality. METHODS: A retrospective review of patients who underwent IP or OP microdiscectomy, laminectomy, anterior cervical discectomy and fusion (ACDF), or cervical disc replacement (CDR) between 2017 and 2021 was conducted using the National Surgical Quality Improvement Program (NSQIP) database. Disparities between Black and White patients in (1) adverse event rates, (2) readmission rates, (3) reoperation rates, (4) nonhome discharge rates, (5) mortality rates, (6) operative times, and (7) hospital LOS between Black and White patients were measured and compared between IP and OP surgical settings. Multivariable logistic regression analyses were used to adjust for potential effects of baseline demographic and clinical differences. RESULTS: Of 81,696 total surgeries, 49,351 (60.4%) were performed as IP and 32,345 (39.6%) were performed as OP procedures. White patients accounted for a greater proportion of IP (88.2% vs 11.8%) and OP (92.7% vs 7.3%) procedures than Black patients. Following IP surgery, Black patients experienced greater odds of serious (OR 1.214, 95% CI 1.077-1.370, p=.002) and minor adverse events (OR 1.377, 95% CI 1.113-1.705, p=.003), readmission (OR 1.284, 95% CI 1.130-1.459, p<.001), reoperation (OR 1.194, 95% CI 1.013-1.407, p=.035), and nonhome discharge (OR 2.304, 95% CI 2.101-2.528, p<.001) after baseline adjustment. Disparities were less prominent in the OP setting, as Black patients exhibited greater odds of readmission (OR 1.341, 95% CI 1.036-1.735, p=.026) but were no more likely than White patients to experience adverse events, reoperation, individual complications, nonhome discharge, or death (p>.050 for all). CONCLUSIONS: Racial inequality in postoperative complications following spine surgery is evident, however disparities in complication rates are relatively less following OP compared to IP procedures. Further work may be beneficial in elucidating the causes of these differences to better understand and mitigate overall racial disparities within the inpatient setting. These decreased differences may also provide promising indication that progress towards reducing inequality is possible as spine care transitions to the OP setting.

INTRODUCTION: Endoscopic techniques are becoming popular among spine surgeons because of their advantages. Though the advantages of endoscopic spine surgery are evident and patients can be discharged home within hours of surgery, readmissions can be sought for incomplete relief of leg pain, recurrent disc herniation, and recurrent leg pain. We aim to find out the factors related to the readmission of patients treated for lumbar pathologies. MATERIALS AND METHODS: This is a retrospective analysis of the data between the time duration of 2012 and 2022. Patients in the age group of 18-85 years, with lumbar disc herniation treated by transforaminal endoscopic lumbar procedures, were included. The patients who were readmitted within 90 days were included in the R Group and those who were not were included in the NR group. Univariable and multivariable logistic regression analyses were used to find the risk factors for 90-day readmission. RESULTS: There were a total of 1542 patients enrolled in this study. Sex, number of episodes before admission, hypertension, smoking, BMI, migration, disc height, disc height index, spondylolisthesis, instability, pelvic tilt (PT), and disc cross-sectional area (CSA) were found significant on univariable analysis. Age, spondylolisthesis, instability and muscle CSA were the only variables that were found to be statistically significant on multivariable analysis. CONCLUSIONS: This study shows that the elderly age group, presence of spondylolisthesis, segmental instability and decreased muscle cross-sectional area are independent risk factors for 90-day hospital readmissions. Patients having the above risk factors should be carefully counseled regarding the possibility of readmission in the future.

OBJECTIVE: To elucidate risk factors for 90-day readmission in anterior cervical discectomy and fusion (ACDF) for small, medium, and large hospitals. To assess differences in length of stay, charges, and complication rates across hospitals of different size. METHODS: A retrospective analysis was performed using elective, single-level ACDF data from 2016 to 2018 in the Healthcare Cost and Utilization Project Nationwide Readmissions Database. Elective single-level ACDF cases were stratified into 3 groups by hospital bed size (small, medium, and large). All-cause complication rates, mean charges, length of stay, and 90-day readmission rates were compared across hospital size. Frequencies of specific comorbidities were compared between readmitted and nonreadmitted patients for each hospital size. Comorbidities significant on univariate analysis were evaluated as independent risk factors for 90-day readmission for each hospital size using multivariate regression. RESULTS: The overall 90-day readmission rate was 6.43% in 36,794 patients, and the rates for small, medium, and large hospitals were 6.25%, 6.28%, and 6.56%, respectively (P = 0.537). Length of stay increased significantly with hospital size (P < 0.001), and small hospitals had the lowest charges (P < 0.001). Although different independent predictors of 90-day readmission were identified for each hospital size, cardiac arrhythmia, chronic pulmonary disease, neurologic disorders, and rheumatic disease were identified as risk factors for hospitals of all sizes. CONCLUSIONS: Hospital size is a determining factor for charges and length of stay associated with elective single-level ACDF. Variation in risk factors for readmission exists across hospital size in context of similar 90-day readmission rates.

OBJECTIVE: A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach. METHODS: A retrospective review of pediatric patients with lumbar disc disease who had undergone microdiscectomy at our institution from 2005 to 2016 was conducted. The preoperative presentation, hospital course, postoperative course, and follow-up data (≥3 years) were reviewed. We evaluated the risk factors for LDH and the surgical outcomes for both groups. RESULTS: A total of 52 pediatric patients had undergone 61 lumbar disc surgeries for LDH in our department from 2005 to 2016. Their average age at surgery was 16.65 years. Of the 61 procedures, 48 (78.7%) had been performed via the minimally invasive spine microdiscectomy approach and 13 (21.3%) via the open microdiscectomy approach. The average body mass index for all cases was 29.3 kg/m2. The average interval to diagnosis was 7.9 months. Of the 61 cases, 21 (34.4%) had been required for patients who were competitive athletes. In addition, 15 had been for LDH related to trauma (24.6%). In 46 of the 61 cases, complete resolution of the symptoms had occurred at the 1-year follow-up visit (79.2% of minimally invasive spine microdiscectomy vs 61.5% of open microdiscectomy). CONCLUSION: Risk factors similar to those for adult LDH, such as an elevated body mass index, can be seen in the pediatric population. However, some unique risk factors such as post-traumatic LDH were found in the pediatric age group. Minimally invasive techniques are demonstrably safe and useful in this patient population.

BACKGROUND: Extended length of stay (LOS) after surgery is costly to the health care system and can be distressing to the patient and family. Previous studies have shown conflicting data on factors associated with increased LOS and are limited by using multiple different surgeries. Our study seeks to analyze factors that are associated with extended LOS. OBJECTIVE: The objective of this study was to analyze data from 2 Food and Drug Administration trials of one-level cervical surgery to identify risk factors that are associated with extended LOS in the hospital. METHODS: Extended LOS was defined to be >1 day. Patients with LOS ≤1 day were compared with those with LOS >1 day. Data from the BRYAN and Prestige ST Trial (n = 1004) were analyzed. Subjects with LOS ≤1 day were compared with those with LOS >1 day. Variables analyzed for their effect on LOS included demographic characteristics, patient-reported outcome measures, preoperative medical conditions, preoperative neurologic status, and intraoperative factors. RESULTS: A total of 912 patients (90.84%) had an LOS ≤1 day and 92 patients (9.16%) had an extended LOS >1 day. Weak narcotic medication use (P = 0.021; odds ratio [OR], 1.72), Nurick gait (P = 0.019; OR, 1.796), and operative time (P < 0.0001; OR, 2.062) were found to significantly affect LOS. CONCLUSIONS: Nurick gait, operative time, and history of weak narcotic use are associated with extended hospital stay. These data may be useful in preoperatively counseling patients, developing quality metrics for hospitals, and helping create financial models for cost/diagnosis-related group reimbursement for single-level anterior cervical surgery.

There is a paucity of data characterizing regional variations in the utilization and costs of conservative management in patients suffering from cervical stenosis prior to anterior cervical discectomy and fusion (ACDF) surgery. An understating of these regional trends becomes critical as outcomes-based reimbursement strategies become standard. The objective of this investigation was to evaluate for regional differences in the utilization and overall costs of maximal non-operative therapy (MNT) prior to ACDF surgery. Medical records from patients with symptomatic cervical stenosis undergoing a ≤3-level index ACDF procedure between 2007 and 2016 were accessed from a large insurance database. Geographic regions (Midwest, Northeast, South, and West) reflected U.S. Census Bureau definitions. MNT utilization within 2-years prior to ACDF surgery was analyzed. An index ACDF surgery was performed in 15,825 patients. Patient regional breakdown was as follows: South (67.6% of patients), Midwest (21.8% of patients), West (8.9% of patients), Northeast (1.6% of patients). Regional variations were identified in the number of patients utilizing NSAIDs (p < 0.001), opioids (p < 0.001), muscle relaxants (p < 0.001), cervical epidural steroid injections (p = 0.001), physical therapy/occupational therapy treatments (p < 0.001), and chiropractor visits (p < 0.001). The West (64.5%) and South (63.5%) had the greatest proportion of patients utilizing narcotics. When normalized by the number of opioid using-patients however, the Northeast (691.4 pills/patient) and South (674.4 pills/patient) billed for the most opioid pills. The total direct cost associated with all MNT prior to index ACDF was $17,255,828. The Midwest ($1,277.72 per patient) and South ($1,047.86 per patient) had the greatest average dollars billed.

OBJECTIVE: The aim of this study was to better understand current treatment trends and revision rates for lumbar disc herniation (LDH) in the workers' compensation (WC) population compared with other payer types. METHODS: This was a retrospective analysis of outpatient claims data from Florida and New York during 2014 to 2016. RESULTS: WC patients were less likely to undergo discectomy in Florida (15% vs 19%; Pâ<â0.001) and New York (10% vs 15%; Pâ<â0.001). The odds of WC patients undergoing revision discectomy were 1.5 times greater than patients covered by private payers or all other non-WC payers (Pâ=â0.002). CONCLUSIONS: WC patients undergo discectomy significantly less often than non-WC counterparts, which may be related to a higher risk of reoperation. New evidence-based treatments, such as annular repair, may be critical to advancing care in this unique population.

BACKGROUND: Posterior percutaneous endoscopic cervical diskectomy (P-PECD) can be used posterior microdiscectomy for cervical disc herniation. But only some small sample sizes of clinical studies have evaluated the efficacy and safety of P-PECD. This study aim to evaluated the efficacy and safety of P-PECD compared with traditional open surgery. METHODS: We will search the following seven electronic databases from their initiation to the May 1, 2020: PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM) and Wanfang database. All randomized controlled trials, non-randomized controlled trials and retrospective case controls that compared the efficacy and safety of P-PECD and traditional open surgery in the treatment of cervical disc herniation will be included. The pooled odds ratio with 95% credible intervals (CIs) was used for the dichotomous variables. The mean difference with 95% CIs was used for the continuous variables. All analyses were conducted by Comprehensive Meta Analysis 2.0. A 2-tailed P valueâ<â0.05 is considered statistically significant. RESULTS: The results of systematic review and meta-analysis will be submitted to a peer-reviewed journal. CONCLUSION: Our study will provide clarity regarding for clinicians to choices best surgical approach for patients with cervical disc herniation. Any changes that need to be made during the process of this study will be explained in the final full-text publication. PROTOCOL REGISTRATION NUMBER: CRD42020164011.

Patients with lumbar intervertebral disc herniation classically trial a brief course of conservative management prior to microdiscectomy surgery. Gender differences have previously been identified in the selection and symptomatic response to commonly-utilized nonoperative treatments. However, whether gender differences exist in the degree and cost of nonoperative therapy in this cohort remains unknown. Therefore, the purpose of this study was to assess for gender differences in the utilization and costs of nonoperative therapy in patients diagnosed with symptomatic lumbar intervertebral disc herniation 3-months prior to undergoing microdiscectomy. Medical records from adult patients diagnosed with a lumbar intervertebral disc herniation undergoing index microdiscectomy procedures from 2007 to 2017 were collected retrospectively from a large insurance database. The utilization of nonoperative therapy within 3-months after initial lumbar herniation diagnosis was determined. A total of 13,106 patients (55.4% Males) underwent index microdiscectomy. Male patients were more likely to fail conservative management and opt for surgery (Males: 2.9% vs. Females: 1.8%, p < 0.0001). A greater percentage of female patients utilized muscle relaxants (p = 0.0049), lumbar epidural steroid injections (p = 0.0007), and emergency department services (p = 0.001). The total direct cost of conservative treatment prior to microdiscectomy was $13,205,924, with males accountable for $7,457,023 (56.5%). When normalized by number of patients utilizing the respective therapy, males used fewer units of NSAIDs (males: 84.2 pills/patient; females: 97.3 pills/patient) and muscle relaxants (males: 77.5 pills/patient; females: 89.0 pills/patient). These results suggest that gender differences exist in the utilization of nonoperative therapies for the management of a lumbar intervertebral herniated disc prior to microdiscectomy surgery.

STUDY DESIGN: Prospective cohort study. OBJECTIVE: To develop and internally validate prognostic models based on commonly collected preoperative data for good and poor outcomes of lumbar microdiscectomy followed by physiotherapy. SUMMARY OF BACKGROUND DATA: Lumbar microdiscectomy followed by physiotherapy is a common intervention for lumbar radiculopathy. Postoperatively, a considerable percentage of people continues to experience pain and disability. Prognostic models for recovery are scarce. METHODS: We included 298 patients with lumbar radiculopathy who underwent microdiscectomy followed by physiotherapy. Primary outcomes were recovery and secondary outcomes were pain and disability at 12 months follow-up. Potential prognostic factors were selected from sociodemographic and biomedical data commonly captured preoperatively. The association between baseline characteristics and outcomes was evaluated using multivariable logistic regression analyses. RESULTS: At 12 months follow-up, 75.8% of the participants met the criterion for recovery. Variables in the model for good recovery included: younger age, leg pain greater than back pain, high level of disability, and a disc herniation at another level than L3-L4. The model for poor recovery included: lower educational level, prior back surgery, and disc herniation at L3-L4. Following internal validation, the explained variance (Nagelkerke R) and area under the curve for both models were poor (≤0.02 and ≤0.60, respectively). The discriminative ability of the models for disability and pain were also poor. CONCLUSION: The outcome of microdiscectomy followed by postoperative physiotherapy cannot be predicted accurately by commonly captured preoperative sociodemographic and biomedical factors. The potential value of other biomedical, personal, and external factors should be further investigated. LEVEL OF EVIDENCE: 3.

OBJECTIVE: To investigate the prevalence and outcomes of surgery for lumbar disc herniation in professional football players. DESIGN: Retrospective case series. SETTING: Sports rehabilitation center. PARTICIPANTS: A period of 10 seasons of the Italian Football First League (Serie A) was retrospectively investigated. Thirty-three teams (for a total of 1960 players) took turns in the 10 seasons, and 42 team doctors were requested to provide information about the number of players who underwent surgery for lumbar disc herniation. INTERVENTION: Survey distributed to team doctors. MAIN OUTCOME MEASURES: Prevalence and match incidence of the lumbar discectomy, proportion of players returning to competition after surgery, recovery time and preintervention and postintervention number of appearances in official matches were analyzed. RESULTS: Eleven players underwent the surgical intervention during the considered period. The prevalence of the surgical treatment was 0.6%, whereas the match incidence was 0.09 cases/1000 match hours. All players returned to competitions 6.0 (3.5-7.7) months after surgery, with no significant difference between different roles. The number of appearances in official matches was comparable during the seasons before and after surgery. CONCLUSIONS: The lumbar discectomy must be considered a rare surgical procedure performed in professional football players. All players returned to competitions after surgery. The postintervention number of appearances in official matches was comparable with the preintervention one.

STUDY DESIGN: Retrospective comparative study. OBJECTIVE: The purpose of this study was to investigate whether preoperative depressive symptoms, measured by mental component score of the Short Form-12 survey (MCS-12), influence patient-reported outcome measurements (PROMs) following an anterior cervical discectomy and fusion (ACDF) surgery for cervical degeneration. SUMMARY OF BACKGROUND DATA: There is a paucity of literature regarding preoperative depression and PROMs following ACDF surgery for cervical degenerative disease. METHODS: Patients who underwent an ACDF for degenerative cervical pathology were identified. A score of 45.6 on the MCS-12 was used as the threshold for depression symptoms, and patients were divided into two groups based on this value: depression (MCS-12 ≤45.6) and nondepression (MCS-12 >45.6) groups. Outcomes including Neck Disability Index (NDI), physical component score of the Short Form-12 survey (PCS-12), and Visual Analogue Scale Neck (VAS Neck), and Arm (VAS Arm) pain scores were evaluated using independent sample t test, recovery ratios, percentage of patients reaching the minimum clinically important difference, and multiple linear regression - controlling for factors such as age, sex, and BMI. RESULTS: The depression group was found to have significantly worse baseline pain and disability than the nondepression group in NDI (Pâ<â0.001), VAS Neck pain (Pâ<â0.001), and VAS Arm pain (Pâ<â0.001) scores. Postoperatively, both groups improved to a similar amount with surgery based on the recovery ratio analysis. The depression group continued to have worse scores than the nondepression group in NDI (Pâ=â0.010), PCS-12 (Pâ=â0.026), and VAS Arm pain (Pâ=â0.001) scores. Depression was not a significant predictor of change in any PROMs based on regression analysis. CONCLUSION: Patients who presented with preoperative depression reported more pain and disability symptoms preoperatively and postoperatively; however, both groups achieved similar degrees of improvement. LEVEL OF EVIDENCE: 3.

INTRODUCTION: Anterior cervical discectomy and fusion (ACDF) remain an effective treatment option for multiple pathologies of the cervical spine. As the health care economic climate has changed, so have reimbursements with a concomitant push toward outpatient procedures. Certificate of Need (CON) programs were established in response to burgeoning health care costs which require states to demonstrate need before expansion of medical facilities. The impact of this program on spine surgery is largely unknown. The purpose of this study was to examine the impact of CON status on reimbursement and utilization trends of ACDF in both inpatient and outpatient settings. MATERIALS AND METHODS: We queried a combined private payer and Medicare database from 2007 to 2015. All single-level ACDFs were identified. We then split each procedure into those performed in CON versus non-CON states. We then further split each group into the inpatient and outpatient settings. Compound annual growth rate (CAGR) was used to compare utilization and reimbursement trends. Reimbursement was adjusted for inflation using the United States Bureau of Labor Statistics consumer price index. RESULTS: A total of 32,727 single-level ACDFs were identified, of which 28,441 were performed in the inpatient setting, and 4286 were performed in the outpatient setting. Reimbursement decreased across all settings, with the most pronounced decrease in the non-CON outpatient setting with an adjusted CAGR of -11.0%. Utilization increased across all groups, although the fastest growth was seen in the outpatient CON setting with a CAGR of 47.7%, and the slowest growth seen in the inpatient non-CON setting at a CAGR of 12.9%. CONCLUSIONS: ACDF utilization increased most rapidly in the outpatient setting, and CON status did not appear to hinder growth. Reimbursement decreased across all settings, with the outpatient setting in non-CON states most affected. Surgeons should be aware of these trends in the changing health care environment.

BACKGROUND: Thus study was a retrospective cohort analysis. Anterior cervical discectomy and fusion (ACDF) has been the gold-standard procedure for single-level degenerative disc disease (DDD). Recently, cervical disc arthroplasty (CDA) has become increasingly prevalent as an alternative intervention. OBJECTIVE: To examine the long-term costs and reoperation rates associated with CDA and ACDF for the treatment of single-level DDD. METHODS: In the present study, we performed a retrospective cohort analysis using the MarketScan database of patients who underwent either ACDF or CDA between 2007 and 2011 and had 5 years postsurgery follow-up. Outcomes related to the health care utilization, cost, and reoperation were analyzed after propensity score matching (PSM). RESULTS: Of 12,434 patients, 12,099 underwent ACDF and 335 CDA. Length of hospital stay and initial hospitalization cost was higher after ACDF compared with CDA. More patients undergoing CDA had early physical therapy compared with patients undergoing ACDF (CDA 30.15% vs. ACDF 22.39%; P = 0.0176). Five years after surgery, there was no significant difference in overall payments between patients undergoing ACDF and patients undergoing CDA. Reoperation rates were comparable at 5 years after the index procedure (CDA 8.06% vs. ACDF 9.25%; P = 0.5862). Patients who underwent ACDF showed decreased use of tramadol after surgery (15.09% before surgery vs. 9.55% after surgery; P < 0.0001). CONCLUSIONS: We found no difference in health care utilization between ACDF and CDA procedures for DDD 5 years after surgery. Also, there was no difference in reoperation rates during the study period. ACDF resulted in significant reduction in overall opioid use after versus before procedure.

STUDY DESIGN: Retrospective study of prospectively collected outcome data. OBJECTIVE: The aim of this study was to investigate reoperation cases and determine whether or not the experience period of a single surgeon was associated with the causes of reoperations following lumbar microendoscopic discectomy for disc herniation (MEDH) and microendoscopic decompression for spinal stenosis (MEDS). SUMMARY OF BACKGROUND DATA: There have been few studies that investigated reoperation cases following MEDH and MEDS. METHODS: Between June 2005 (first experience of MEDH) and September 2013, the same surgeon had been using MEDH and/or MEDS on 441 consecutive patients. The follow-up rate was 89.3%. The causes and rates of reoperations (RORs) were determined at 5 years after the initial operations. We also investigated the experience period of a single surgeon (EPS, interval between June 2005 and initial operation: median, 37 months). RESULTS: The 5-year reoperation rate for all patients combined was 12.4% (49/394). The main causes for reoperations were recurrence of disc herniation (ROR, 7.01%) and increase of postoperative spondylolisthesis and/or instability (ROR, 9/394 = 2.28%); two of the nine cases were caused by excessive decompression, and the EPSs were 11 and 16 months. The other causes for reoperations were postoperative epidural hematoma (ROR, 0.76%; median EPS, 20 months), insufficient decompression (ROR, 0.25%; EPS, 17 months), and residual segmental scoliosis (ROR, 7.69%); two segmental scoliosis cases did not provide relief from sciatica, and therefore L4/5 transforaminal interbody fusions were performed. CONCLUSION: Postoperative epidural hematoma and excessive or insufficient decompression were often observed in the initial series of patients as the causes for reoperations. We think that it is important to be aware of and prevent such potential problems in any initial series of patients, as there are limitations to any surgical indications for the use of microendoscopic decompression for degenerative segmental scoliosis because of original traction and/or kinking of nerve roots.

STUDY DESIGN: Prospective observational study OBJECTIVE.: The aim of this study was to record daily opioid use and pain levels after 1-level lumbar decompression or microdiscectomy. SUMMARY OF BACKGROUND DATA: The standardization of opioid-prescribing practices through guidelines can decrease the risk of misuse and lower the number of pills available for diversion in this high-risk patient population. However, there is a paucity of quantitative data on the "minimum necessary amount" of opioid appropriate for post-discharge prescriptions. METHODS: At two institutions between September 2017 and 2018, we prospectively enrolled 85 consecutive adult patients who underwent one-level lumbar decompression or microdiscectomy. Patients with a history of opioid dependence were excluded. Daily opioid consumption and pain scores were collected using an automated text-messaging-based platform for 6 weeks or until consumption ceased. Refills during the study period were monitored. Patients were asked for the number of pills left over and the method of disposal. Opioid use was converted to oral morphine equivalents (OMEs). Results are also reported in terms of "pills" (oxycodone 5âmg equivalents) to facilitate clinical applications. Risk factors were compared between patients in the top and bottom half of opioid consumption. RESULTS: Total opioid consumption ranged from 0 to 118 pills, with a median consumption of 32 pills (236.3 OME). Seventy-five percent of patients consumed ≤57 pills (431.3 OME). Mean Numeric Rating Scale pain scores declined steadily over the first 2 weeks. By postoperative day 7 half of the study population had ceased taking opioids altogether. Only 22.4% of patients finished their initial prescription, and only 9.4% of patients obtained a refill. CONCLUSION: These data may be used to formulate evidence-based opioid prescription guidelines, establish benchmarks, and identify patients at the higher end of the opioid use spectrum. LEVEL OF EVIDENCE: 2.

BACKGROUND: Dysphagia is one of the most common complications of surgical procedures in the anterior cervical spine, and can persist up to 2 years postoperatively. Corticosteroids are relatively safe and inexpensive for treating various inflammatory conditions. Perioperative corticosteroid administration for anterior cervical spine procedures may effectively minimize postoperative dysphagia, potentially leading to better outcomes, decreased readmission rates, and improved patient satisfaction. The purpose of this study was to determine the efficacy of perioperative corticosteroids in decreasing the severity and duration of dysphagia following single-level and multilevel anterior cervical spine procedures. METHODS: Seventy-four patients undergoing elective anterior cervical surgical procedures for degenerative conditions were recruited. Patients with prior cervical procedures; with a diagnosis of fracture, malignancy, or infection; or requiring combined anterior-posterior procedures were excluded. Patients were randomized to perioperative intravenous dexamethasone or saline solution. Doses were administered before incision and at 8 and 16 hours postoperatively. Investigators and patients were blinded to the treatment throughout the study. Dysphagia outcomes were assessed with use of the Bazaz dysphagia scale and the Dysphagia Short Questionnaire (DSQ) at 1 day, 2 days, 1 week, 2 weeks, 1 month, 3 months, 6 months, and 12 months postoperatively. Statistical analysis was performed comparing means and standard deviations; significance was set at p < 0.05. Clinical outcomes were measured with use of the Quality of Life-12 and Neck Disability Index. RESULTS: Sixty-four patients were included in the analysis. There were 49 anterior cervical discectomies and fusions, 8 corpectomies, 1 hybrid procedure (corpectomy and adjacent discectomy), and 6 single-level arthroplasties. Patients who received corticosteroids had significantly better dysphagia scores on both the Bazaz scale and DSQ at most time points up to 6 months postoperatively (p < 0.05). On subgroup analysis, patients with multilevel (≥2-level) fusion benefited significantly from corticosteroids on both scales, whereas those with single-level procedures did not. There were no short-term wound complications or infections, and length of stay and fusion rates were comparable. CONCLUSIONS: Perioperative administration of corticosteroids can reduce dysphagia symptoms following multilevel anterior cervical procedures. Benefit was noted immediately and up to 6 months postoperatively. There was no significant effect on short-term wound-healing, infection rates, length of stay, or fusion rates. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: To investigate the adjacent segment kinematics, including the instantaneous axis of rotation (IAR) and range of motion (ROM), after anterior cervical discectomy and fusion (ACDF), and to compare between ACDF with zero-profile anchored spacer (ACDF-Z) and ACDF with plate (ACDF-P). METHODS: Eighty-seven patients (ACDF-Z = 63; ACDF-P = 24) were included. Flexion, extension and neutral cervical radiographs were obtained before operation and at 1-year follow-up. C2-C7 ROM, adjacent segment ROMs, and IARs were measured. Clinical evaluation was based on the Visual Analogue Scale, Neck Disability Index, and Japanese Orthopaedic Association score. RESULTS: After ACDF-Z, location of the superior IAR-AP reduced 1.60 mm, which represents 8% of the vertebral body (P < 0.001), and location of the inferior IAR-SI reduced 2.19 mm, 17% of the vertebral body (P = 0.02). After ACDF-P, location of the superior IAR-AP increased 0.8 mm, which means 6% of the vertebral body (P = 0.008), location of the inferior IAR-AP increased 3.34 mm, 22% of the vertebral body (P = 0.03), and location of the inferior IAR-SI reduced 3.14 mm, 25% of the vertebral body (P = 0.002). C2-C7 ROM significantly decreased after both ACDF-Z and ACDF-P (P < 0.001). Neither ACDF-Z nor ACDF-P significantly affected the adjacent segment ROMs (P > 0.05). CONCLUSIONS: Both ACDF-Z and ACDF-P significantly impacted cervical kinematics, although both procedures obtained satisfactory clinical results in the treatment of cervical spondylosis. After both ACDF-Z and ACDF-P, C2-C7 ROM decreased significantly, while adjacent segment ROMs were preserved. ACDF-Z and ACDF-P impact the location of adjacent segment IAR-SI in similar way, while impact the location of adjacent segment IAR-AP in diverse ways.
