RESUMO
Previous studies have shown a relationship between cigarette use and pain but never in the setting of traumatic spinal cord injury (TSCI). Therefore, the objectives of this study were to (1) determine whether smokers with TSCI experience increased pain compared with nonsmokers with TSCI and (2) determine whether smokers with TSCI experience worse functional outcomes than nonsmokers with TSCI. A retrospective analysis of the National Spinal Cord Injury Statistical Center database was performed. Pain severity, interference, and functional outcomes were compared between 514 nonsmokers and 124 smokers with American Spinal Injury Association (ASIA) C/D TSCI. Smokers reported higher scores for pain severity and interference compared with nonsmokers. These findings were significant on multivariable analysis. Smokers also reported higher rates of job loss compared with nonsmokers, but this finding was not significant on multivariable analysis. Smoking may be an independent risk factor for increased pain severity and interference in the setting of TSCI. (Journal of Surgical Orthopaedic Advances 33(2):103-107, 2024).

STUDY DESIGN: Level III evidence-retrospective cohort. OBJECTIVE: The purpose of this study was to (1) determine whether longer CDA operative time increases the risk of 30-day postoperative complications, (2) analyze the association between operative time and subsequent health care utilization, and (3) discharge disposition. BACKGROUND: Cervical disk arthroplasty (CDA) most commonly serves as an alternative to anterior cervical discectomy and fusion (ACDF) to treat cervical spine disease, however, with only 1600 CDAs performed annually relative to 132,000 ACDFs, it is a relatively novel procedure. METHODS: A retrospective query was performed identifying patients who underwent single-level CDA between January 2012 and December 2018 using a nationwide database. Differences in baseline patient demographics were identified through univariate analysis. Multivariate logistic regression was performed to identify associations between operative time (reference: 81-100 min), medical/surgical complications, and health care utilization. RESULTS: A total of 3681 cases were performed, with a mean patient age of 45.52 years and operative time of 107.72±49.6 minutes. Higher odds of length of stay were demonstrated starting with operative time category 101-120 minutes (odds ratio: 2.164, 95% CI: 1.247-3.754, P=0.006); however, not among discharge destination, 30-day unplanned readmission, or reoperation. Operative time <40 minutes was associated with 10.7x odds of nonhome discharge, while >240 minutes was associated with 4.4 times higher odds of LOS>2 days (P<0.01). Increased operative time was not associated with higher odds of wound complication/infection, pulmonary embolism, deep venous thrombosis, or urinary tract infections. CONCLUSIONS: Prolonged CDA operative time above the reference 81-100 minutes is independently associated with increased length of stay, but not other significant health care utilization parameters, including discharge disposition, readmission, or reoperation. There was no association between prolonged operative time and 30-day medical/surgical complications, including wound complications, infections, pulmonary embolism, or urinary tract infection.
RESUMO
BACKGROUND: Vertebral compression fractures (VCFs) are typically treated nonoperatively but can be treated with either kyphoplasty or vertebroplasty when indicated. The decision to treat patients with/without surgical intervention is dependent on the severity of deformity and patient risk profile. The aims of this study were to: 1) compare baseline patient demographics, 2) identify risk factors of patients undergoing operative vs. nonoperative management, and 3) identify patient-specific risk factors associated with postoperative readmissions. METHODS: This retrospective database study used patient information from January 1st, 2010, to October 31st, 2021. Cohorts were identified by patients diagnosed with VCFs through International Classification of Disease, Ninth Revision (ICD-9), ICD-10 codes, identifying those undergoing kyphoplasty/vertebroplasty via Current Procedural Terminology codes. The 2 research domains utilized in this investigation were baseline demographic profiles of patients who underwent kyphoplasty or vertebroplasty for treatment of VCFs, and those who underwent nonoperative management served as the control cohort. RESULTS: Of the 703,499 patients diagnosed with VCFs, 76,126 patients (10.8%) underwent kyphoplasty or vertebroplasty within 90 days of diagnosis of a VCF. Univariate analysis demonstrated female sex was associated with increased risk of undergoing surgical management for VCF (P < 0.0001). Several comorbidities were significantly associated with increased rates of readmission including hypertension, tobacco use, coronary artery disease, and chronic obstructive pulmonary disease (P < 0.0001 for all). CONCLUSIONS: This study highlights specific comorbidities that are significantly associated with higher rates of kyphoplasty or vertebroplasty for the treatment of thoracolumbar wedge compression fractures and increased risk for 90-day postoperative hospital readmission.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The purpose of this study is to compare the impact of anterior cervical decompression and fusion (ACDF) versus posterior cervical decompression and fusion (PCDF) for the treatment of acute traumatic central cord syndrome (CCS) on hospital episodes of care in terms of (1) cost, (2) length of hospital stay, and (3) discharge destination. SUMMARY OF BACKGROUND DATA: Acute traumatic CCS is the most common form of spinal cord injury in the United States. CCS is commonly treated with surgical decompression and fusion. Hospital resource utilization based on surgical approach remains unclear. METHODS: Patients undergoing ACDF and PCDF for acute traumatic CCS were identified using the 2019 Medicare Provider Analysis and Review Limited Data Set and Centers for Medicare and Medicaid Services 2019 Impact File. Multivariate models for hospital cost of care, length of stay, and discharge destination were performed, controlling for confounders. Subanalysis of accommodation and revenue center cost drivers was performed. RESULTS: There were 1474 cases that met inclusion criteria: 673 ACDF (45.7%) and 801 PCDF (54.3%). ACDF was independently associated with a decreased cost of $9802 ( P <0.001) and a 59.2% decreased risk of discharge to nonhome destinations (adjusted odds ratio: 0.408, P <0.001). The difference in length of stay was not statistically significant. On subanalysis of cost drivers, ACDF was associated with decreased charges ($55,736, P <0.001) compared with PCDF, the largest drivers being the intensive care unit ($15,873, 28% of total charges, P <0.001) and medical/surgical supply charges ($19,651, 35% of total charges, P <0.001). CONCLUSIONS: For treatment of acute traumatic CCS, ACDF was associated with almost $10,000 less expensive cost of care and a 60% decreased risk of discharge to nonhome destination compared with PCDF. The largest cost drivers appear to be ICU and medical/surgical-related. These findings may inform value-based decisions regarding the treatment of acute traumatic CCS. However, injury and patient clinical factors should always be prioritized in surgical decision-making, and increased granularity in reimbursement policies is needed to prevent financial disincentives in the treatment of patients with CCS better addressed with posterior approach-surgery.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: The study aimed to (1) compare baseline demographics of patients undergoing surgery for SEA who were/were not readmitted; (2) identify risk factors for 90-day readmissions; and (3) quantify 90-day episode-of-care health care costs. BACKGROUND: Spinal epidural abscess (SEA), while rare, occurring ~2.5-5.1/10,000 admissions, may lead to permanent neurologic deficits and mortality. Definitive treatment often involves surgical intervention via decompression. METHODS: A search of the PearlDiver database from 2010 to 2021 for patients undergoing decompression for SEA identified 4595 patients. Cohorts were identified through the International Classification of Disease, Ninth Revision (ICD-9), ICD-10, and Current Procedural Terminology codes. Baseline demographics of patients who were/were not readmitted within 90 days following decompression were aggregated/compared, identifying factors associated with readmission. Using Bonferroni correction, a P -value<0.001 was considered statistically significant. RESULTS: Readmission within 90 days of surgical decompression occurred in 36.1% (1659/4595) of patients. While age/gender were not associated with readmission rate, alcohol use disorder, arrhythmia, chronic kidney disease, ischemic heart disease, and obesity were associated with readmission. Readmission risk factors included fluid/electrolyte abnormalities, obesity, paralysis, tobacco use, and pathologic weight loss ( P <0.0001). Mean same-day total costs ($17,920 vs. $8204, P <0.001) and mean 90-day costs ($46,050 vs. $15,200, P <0.001) were significantly higher in the readmission group. CONCLUSION: A substantial proportion of patients (36.1%) are readmitted within 90 days following surgical decompression for SEA. The top 5 risk factors in descending order are fluid/electrolyte abnormalities, pathologic weight loss, tobacco use, pre-existing paralysis, and obesity. This study highlights areas for perioperative medical optimization that may reduce health care utilization.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To compare elective single-level anterior cervical discectomy and fusion (ACDF) versus posterior cervical decompression and fusion (PCDF) for degenerative cervical myelopathy (DCM) in terms of (1) cost, (2) length of hospital stay, and (3) discharge destination in Medicare patients. A sub-analysis of potential cost drivers was also performed. BACKGROUND: In the era of value-based medicine, there is substantial interest in reducing the cost of care. Both ACDF and PCDF are used to treat DCM but carry different morbidity and risk profiles that can impact hospital resource utilization. However, this has not been assessed on a national level. METHODS: Patients undergoing single-level elective ACDF and PCDF surgery were identified using the 2019 Medicare Provider Analysis and Review (MedPAR) Limited Data Set (LDS) and Centers for Medicare and Medicaid Services (CMS) 2019 Impact File. Multivariate models of hospital cost of care, length of stay, and discharge destination were performed, controlling for confounders. A univariate sub-analysis of 9 revenue centers was performed. RESULTS: In all, 3942 patients met the inclusion criteria. The mean cost of elective single-level cervical fusion for myelopathy was $18,084±10,783, and the mean length of stay was 2.45±2.95 d. On multivariate analysis, ACDF was independently associated with decreased cost of $5,814 ( P <0.001), shorter length of stay by 1.1 days ( P <0.001), and decreased risk of nonhome discharge destination by 58% (adjusted odds ratio: 0.422, P <0.001).On sub-analysis of 9 revenue centers, medical/surgical supply ($10,497, 44%), operating room charges ($5401, 23%), and accommodations ($3999, 17%) were the largest drivers of charge differences. CONCLUSIONS: Single-level elective primary ACDF for DCM was independently associated with decreased cost, decreased hospital length of stay, and a lower rate of nonhome discharge compared with PCDF. Medical and surgical supply, operating room, and accommodation differences between ACDF and PCDF are potential areas for intervention. Increased granularity in reimbursement structures is warranted to prevent the creation of disincentives to the treatment of patients with DCM with pathology that is better addressed with PCDF. LEVEL OF EVIDENCE: Level-III Retrospective Cohort Study.

Hematoma after anterior cervical spine surgery can result in neurologic and airway compromise. Current guidelines recommend an international normalized ratio (INR) <1.5 before elective spine surgery because of increased complications. The risk associated with an INR of 1.25 is not well studied. The purpose of this study was to determine the risk of complications associated with a preoperative INR >1.25 and ≤1.5 in patients undergoing elective anterior cervical spine surgery. The American College of Surgeons National Surgical Quality Improvement Program database was queried. Patients undergoing elective anterior cervical spine surgery from 2012 to 2016 who had an INR recorded within 24 hours of surgery were included. Outcomes of interest included postoperative hematoma requiring surgery, 30-day mortality, and 30-day readmissions and reoperations. A total of 2949 patients were included. The incidence of a postoperative hematoma that required surgical management was 0.2%, 0.6%, and 4.5% in the INR≤1, 1

STUDY DESIGN: Retrospective Case-Control Study. OBJECTIVES: The objectives were to determine whether patients from poor social determinants of health, undergoing primary 1- to 2-level lumbar fusion, demonstrate differences in (1) medical complications, (2) emergency department (ED) utilizations, (3) readmission rates, and (4) costs of care. SUMMARY OF BACKGROUND DATA: Measures of socioeconomic disadvantage may enable improved targeting and prevention of potentially increased health care utilization. The Area Deprivation Index (ADI) is a validated index of 17 census-based markers of material deprivation and poverty. MATERIALS AND METHODS: A retrospective query of the 2010-2020 PearlDiver database was performed for primary 1- to 2-level lumbar fusions for degenerative lumbar pathology. High ADI (scale: 0-100) is associated with a greater disadvantage. Patients with high ADI (90%+) were 1:1 propensity score matched to controls (ADI: 0-89%) by age, sex, and Elixhauser Comorbidity Index. This yielded 34,442 patients, evenly matched between cohorts. Primary outcomes were to compare 90-day complications, ED utilizations, readmissions, and costs of care. Multivariable logistic regression models computed the odds ratios (OR) of ADI on complications, ED utilizations, and readmissions. P -values <0.05 were significant. RESULTS: Patients with a high ADI incurred higher rates and odds of developing respiratory failures (1.17% vs. 0.87%; OR: 1.35, P =0.005). Acute kidney injuries (2.61% vs. 2.29%; OR: 1.14, P =0.056), deep venous thromboses (0.19% vs. 0.17%; OR: 1.14, P =0.611), cerebrovascular accidents (1.29% vs. 1.31%; OR: 0.99, P =0.886), and total medical complications (23.35% vs. 22.93%; OR: 1.02, P =0.441) were similar between groups. High ADI patients experienced higher rates and odds of ED visits within 90 days (9.67% vs. 8.91%; OR: 1.10, P =0.014) and overall 90-day expenditures ($54,459 vs. $47,044; P <0.001). CONCLUSIONS: Socioeconomically disadvantaged patients have increased rates and odds of respiratory failure within 90 days. ED utilization within 90 days of surgery was higher in socioeconomically disadvantaged patients. Social determinants of health could be used to inform health care policy and improve postdischarge care. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: With the advent of bundled care payments for spine surgery, there is increasing scrutiny on the costs and resource utilization associated with surgical care. The purpose of this study was to compare (1) the total cost of the hospital episode of care and (2) discharge destination between White, Black, and Hispanic patients receiving elective anterior cervical decompression and fusion for degenerative cervical myelopathy (DCM) in Medicare patients. METHODS: The 2019 Medicare Provider Analysis and Review Limited Data Set and the 2019 Impact File were used for this project. Multivariate models were created for total cost and discharge destination, controlling for confounders found on univariate analysis. We then performed a subanalysis for differences in specific cost-center charges. RESULTS: There were 11,506 White (85.4%), 1,707 Black (12.7%), and 261 Hispanic (1.9%) patients identified. There were 6,447 males (47.8%) and 7,027 females (52.2%). Most patients were between 65 to 74 years of age (n = 7,101, 52.7%). The mean cost of the hospital episode was $20,919 ± 11,848. Most patients were discharged home (n = 11,584, 86.0%). Race/ethnicity was independently associated with an increased cost of care (Black: $783, Hispanic: $1,566, P = 0.001) and an increased likelihood of nonhome discharge (Black: adjusted odds ratio: 1.990, P < 0.001, Hispanic: adjusted odds ratio: 1.822, P < 0.001) compared with White patients. Compared with White patients, Black patients were charged more for accommodations ($1808), less for supplies (-$1780), and less for operating room (-$1072), whereas Hispanic patients were charged more ($3556, $7923, and $5162, respectively, P < 0.05). CONCLUSION: Black and Hispanic race/ethnicity were found to be independently associated with an increased cost of care and risk for nonhome discharge after elective anterior cervical decompression and fusion for DCM compared with White patients. The largest drivers of this disparity appear to be accommodation, medical/surgical supply, and operating room-related charges. Further analysis of these racial disparities should be performed to improve value and equity of spine care for DCM.

PURPOSE: Most randomized trials comparing open carpal tunnel release (OCTR) to endoscopic carpal tunnel release (ECTR) are not specific to a working population and focus mainly on how surgical technique has an impact on outcomes. This study's primary goal was to evaluate factors affecting days out of work (DOOW) following carpal tunnel release (CTR) in a working population and to evaluate for differences in medical costs, indemnity payments, disability ratings, and opioid use between OCTR and ECTR with the intent of determining whether one or the other surgical method was a determining factor. METHODS: Using the Ohio Bureau of Workers' Compensation claims database, individuals were identified who underwent unilateral isolated CTR between 1993 and 2018. We excluded those who were on total disability, who underwent additional surgery within 6 months of their index CTR, including contralateral or revision CTR, and those not working during the same month as their index CTR. Outcomes were evaluated at 6 months after surgery. Multivariable linear regression was performed to evaluate covariates associated with DOOW. RESULTS: Of the 4596 included participants, 569 (12.4%) and 4027 (87.6%) underwent ECTR and OCTR, respectively. Mean DOOW were 58.4 for participants undergoing OCTR and 56.6 for those undergoing ECTR. Carpal tunnel release technique was not predictive of DOOW. Net medical costs were 20.7% higher for those undergoing ECTR. Multivariable linear regression demonstrated the following significant predictors of higher DOOW: preoperative opioid use, legal representation, labor-intensive occupation, increasing lag time from injury to filing of a worker's compensation claim, and female sex. Being married, higher income community, and working in the public sector were associated with fewer DOOW. CONCLUSIONS: In a large statewide worker's compensation population, demographic, occupational, psychosocial, and litigatory factors have a significant impact on DOOW following CTR, whereas differences in surgical technique between ECTR and OCTR did not. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

STUDY DESIGN: This was a retrospective cross-sectional analysis. OBJECTIVE: The objective of this study was to estimate the incremental health care costs of depression in patients with spine pathology and offer insight into the drivers behind the increased cost burden. SUMMARY OF BACKGROUND DATA: Low back pain is estimated to cost over $100 billion per year in the United States. Depression has been shown to negatively impact clinical outcomes in patients with low back pain and those undergoing spine surgery. MATERIALS AND METHODS: Data was collected from the Medical Expenditure Panel Survey from 2007 to 2015. Spine patients were identified and stratified based on concurrent depression International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Health care utilization and expenditures were analyzed between patients with and without depression using a multivariate 2-part logistic regression with adjustments for sociodemographic characteristics and Charlson Comorbidity Index. RESULTS: A total of 37,094 patients over 18 years old with a spine condition were included (mean expenditure: $7829±241.67). Of these patients, 7986 had depression (mean expenditure: $11,455.41±651.25) and 29,108 did not have depression (mean expenditure: $6837.89±244.51). The cost of care for spine patients with depression was 1.42 times higher (95% confidence interval, 1.34-1.52; P<0.001) than patients without depression. The incremental expenditure of spine patients with depression was $3388.22 (95% confidence interval, 2906.60-3918.96; P<0.001). Comorbid depression was associated with greater inpatient, outpatient, emergency room, home health, and prescription medication utilization and expenditures compared with the nondepressed cohort. CONCLUSIONS: Spine patients with depression had significantly increased incremental economic cost of nearly $3500 more annually than those without depression. When extrapolated nationally, this translates to an additional $27.5 billion annually in incremental expenditures that can be attributed directly to depression among spine patients, which equates to roughly 10% of the total estimated spending on depression nationally. Strategies focused on optimizing the treatment of depression have the potential for dramatically reducing health care costs in spine surgery patients.

The objective of this study was to determine the impact of smoking on clinical outcomes in workers' compensation (WC) patients receiving spinal cord stimulation (SCS). One hundred and ninety-six patients from the Ohio Bureau of Workers' Compensation were identified who received SCS with implantation occurring between 2007-2012. Patients were divided into smokers (n = 120) and nonsmokers (n = 76). Population characteristics before and after implantation were analyzed between the two groups. A multivariate logistic regression was run to determine predictors of return to work (RTW) status. Our regression determined smoking (p = 0.006; odds ratio [OR] = 0.260) and body mass index (p = 0.036; OR = 0.905) to be negative predictors of RTW status. After implantation, smokers were less likely to RTW after 6 months and had higher pain scores after 6 and 12 months. Both smokers and nonsmokers had significance reductions in opioid use after SCS implantation. (Journal of Surgical Orthopaedic Advances 30(3):185-189, 2021).

The optimal timing of lumbar diskectomy in patients with lumbar disk herniation and radiculopathy has not been studied in the workers' compensation (WC) population. A total of 10,592 patients received lost-work compensation from the Ohio Bureau of Workers' Compensation for a lumbar disk herniation between 2005 and 2012. The primary outcome was whether subjects return to work (RTW). To determine the impact time to surgery had on RTW status, the authors performed a multivariate logistic regression analysis. They compared other secondary outcomes using chi-square and t tests. The authors identified 1287 WC patients with single-level disk herniation and radiculopathy. Average time from injury to surgery was 364 days (range, 2-2710 days). The WC patients with shorter duration of radiculopathy before diskectomy had higher RTW rates; fewer physical therapy, chiropractic, and psychotherapy sessions; and fewer postoperative diagnoses of psychological illnesses (P<.05). A multivariate logistic regression model showed that time to surgery was an independent, negative predictor of RTW (odds ratio [OR], 0.97 per month; P<.01). Legal representation (OR, 0.56; P<.01), psychological comorbidity (OR, 0.32; P=.01), and mean household income (OR, 1.01 per $1000; P<.01) also significantly affected RTW status. These results confirm that the duration of radiculopathy due to single-level lumbar disk herniation has a predictive value for the WC population undergoing diskectomy. Within 12 weeks of injury, post-diskectomy patients do reasonably well, with 70.0% of subjects returning to work. [Orthopedics. 2021;44(1):e43-e49.].

BACKGROUND: Symptomatic post-operative lumbar epidural hematoma (PLEH) is a complication of lumbar spine surgery that can cause permanent neurologic consequences through compression of the cauda equina and nerve roots. QUESTIONS/PURPOSES: We sought to investigate the incidence, timing, and risk factors for symptomatic epidural hematomas following posterior lumbar decompression, as well as to identify additional post-operative complications associated with symptomatic lumbar epidural hematomas. METHODS: Elective lumbar spine procedures were identified in the National Surgical Quality Improvement Program (NSQIP) database between 2012 and 2016. Analyzed predictors of reoperation or readmission within 30 days for symptomatic PLEH included demographics, comorbidities, pre-operative laboratory values, peri-operative characteristics, and post-operative complications. RESULTS: There were 75,878 cases included in the analysis. The incidence rate of symptomatic PLEH was 0.27% (n = 206), 54.4% (n = 112) of which occurred within 5 days of the procedure. Increased age, obesity (body mass index of 35 or higher), peri-operative transfusion, multilevel surgery (two or more levels), dural tear repair, and microscope use were independently associated with PLEH. Post-operative complications associated with PLEH included surgical site infection and urinary tract infection. CONCLUSIONS: Readmission or reoperation for symptomatic PLEH following elective lumbar spine surgery is rare and can occur many days or weeks after a procedure. There are modifiable risk factors for PLEH and associated additional post-operative complications that physicians should be suspicious of following posterior lumbar decompression.
RESUMO
Diabetes currently affects over 25 million Americans, with the elderly carrying much of the disease burden. It's well known that diabetes increases the risk of surgical complications, but few studies have analyzed its effects on reoperation rates after single-level lumbar discectomy. Data was obtained using the commercially available Explorys software, which houses de-identified data for several healthcare systems. A database search was conducted to find all patients who'd undergone a lumbar discectomy. Scoliosis, spondylolisthesis, smoking history and obesity were excluded as possible confounding variables, after which 31,210 patients remained. Of them, 950 were found to have undergone a revision discectomy within 2 years. Those with diabetes were found to have a relative risk of 1.29 for revision discectomy compared to those who did not, 95% confidence interval (95% CI) 1.10-1.52, p < 0.002. These findings contribute to the importance of modifiable risk factor assessment preoperatively and their effects on surgical complications.

The purpose of this study was to examine the relationship between smoking and back pain in a cross-sectional analysis. Using the Osteoarthritis Initiative database, a multi-center, longitudinal, observational cohort study with 4796 participants, we examined the prevalence of back pain and of limitations in activity due to back pain, as well as the frequency and severity of back pain in participants who were current smokers compared to those who had never smoked. Data was evaluated using binary and ordinal logistic regression analyses. An increase in prevalence, frequency and severity of back pain was strongly associated with smoking. This demonstrates a relationship between smoking and back pain; however, further studies are needed to evaluate causation. (Journal of Surgical Orthopaedic Advances 29(3):165-168, 2020).

Removal of a herniated disk that is causing neural compression is among the most common indications for spinal surgery. Previous population database studies of risk factors for reoperation after this procedure analyzed small to medium numbers of patients. To date, no study has concurrently assessed the effect of modifiable risk factors, such as smoking and nicotine dependence, with a large number of patients. Data were obtained with commercially available software that houses de-identified data for several major US health care systems. A database search was conducted to find all patients who had undergone lumbar diskectomy. Obesity, scoliosis, spondylolisthesis, and depression were excluded as possible confounding variables. The remaining patients were divided into smoking and nonsmoking groups. Those who had undergone revision lumbar diskectomy within 2 years were counted. Pearson's chi-square statistical test was used to determine significance at P<.05. Of the 50 million patient records in the software platform, 53,360 patients were identified who had undergone single-level lumbar diskectomy. Of these, 26,980 fulfilled the inclusion criteria. A total of 890 of those patients had undergone revision lumbar diskectomy within 2 years of their original procedure. Those who smoked were found to have a relative risk of 2.47 compared with nonsmokers (95% confidence interval, 2.17-2.82; P<.0001). Nicotine dependence and smoking had a significant effect on the rate of reoperation. These findings support the importance of preoperative assessment of modifiable risk factors and their effects on surgical complications. [Orthopedics. 2020;43(5):e438-e441.].

BACKGROUND: Optimal surgical management of displaced femoral neck fractures (dFNFs) in subjects 45-65 years old is unclear. We evaluated days out of work (dOOW), medical and indemnity costs, and secondary outcomes at 2 years between internal fixation (IF), hemiarthroplasty (HA), and total hip arthroplasty (THA) among workers' compensation (WC) subjects with isolated dFNFs aged 45-65. METHODS: We retrospectively identified 105 Ohio Bureau of WC subjects with isolated subcapital dFNFs aged 45-65 with 2 years of follow-up. In total, 37 (35.2%) underwent IF, 23 (21.9%) THA, and 45 (42.9%) HA from 1993 to 2017. Linear regression was used to determine if surgery type was predictive of dOOW postoperatively and to evaluate inflation-adjusted net medical and indemnity costs at 2 years. RESULTS: IF subjects were younger (52.9) than THA (58.5, P < .001) and HA (58.4, P < .001) subjects. Mean dOOW for THA subjects at 6 months, 1 year, and 2 years was 90.8, 114.6, and 136.6. This was significantly lower than IF (136.3, 182.0, 236.6) and HA (114.6, 153.3, 247.6) subjects at all time points. Medical costs were similar. Mean indemnity costs were 3.0 and 2.4 times higher among IF (P < .001) and HA (P = .007) groups compared to THA, respectively. Rates of postoperative permanent disability awards were 13.0%, 43.2%, and 35.6% for the THA, IF, and HA groups (P = .050). IF and HA subjects had a 24.3% and 11.1% revision rate. Overall, 77.8% and 100% of the IF and HA revisions were conversions to THA. CONCLUSION: WC subjects aged 45-65 with dFNFs treated with THA had fewer dOOW, lower indemnity costs, and less disability at 2 years. Longer follow-up will help determine the durability and long-term outcomes of these surgeries.

The prevalence of obesity has been rising, creating a major public health concern. While several studies have shown obesity to increase the risk of surgical complications, few have analyzed its effects on reoperation, specifically after singlelevel lumbar discectomy. Data was obtained using the commercially available Explorys software that houses deidentified data for several major healthcare systems. A database search was used to find all patients who had undergone a lumbar discectomy. Scoliosis, spondylolisthesis, smoking history and depression were excluded as possible confounding variables, after which 25,960 patients remained. Of them, 690 were found to have undergone a revision discectomy within 2 years. Those who were obese were found to have a relative risk of 1.64 for revision discectomy compared to those who were nonobese, 95% confidence interval (95%CI) 1.322.03, p 0.0001. These findings contribute to the importance of modifiable risk factor assessment preoperatively and their effects on surgical complications.

This study sought to determine the impact of time to surgery on clinical outcomes in patients with spondylolisthesis in the workers' compensation (WC) population. There is conflicting evidence regarding the effect of time to surgery on patients with spondylolisthesis. Patients receiving WC are known to have worse outcomes following spine surgery compared with the general population. A total of 791 patients from the Ohio Bureau of Workers' Compensation were identified who underwent lumbar fusion for spondylolisthesis between 1993 and 2013. The patients were divided into those who had surgery within 2 years of injury date and after 2 years. Confounding factors were corrected for in a multivariate logistic regression to determine predictors of return to work (RTW) status. Multivariate logistic regression determined that longer time to surgery (P=.003; odds ratio, 0.89 per year), age at index fusion (P=.003; odds ratio, 0.98 per year), and use of physical therapy before fusion (P=.008; odds ratio, 0.54) were negative predictors of RTW status. Patients who had surgery within 2 years were more likely to RTW and have fewer days absent from work, lower medical costs, and fewer sessions of psychotherapy, physical therapy, and chiropractor care. The authors demonstrated that for WC patients with spondylolisthesis, longer time to surgery was a negative predictor of RTW status. Patients who had surgery within 2 years of injury date were significantly more likely to RTW compared with after 2 years. [Orthopedics. 2020;43(3):154-160.].
