RESUMO
OBJECTIVE: To compare the 2-year reoperation rates for adjacent segment disease between patients with pelvic incidence-lumbar lordosis (PI-LL) mismatch postoperatively and patients with normal PI-LL measurements. METHODS: Patients undergoing elective 1- to 2-level lumbar fusion for degenerative conditions between 2016 and 2018 were retrospectively reviewed. Spinopelvic radiographic parameters immediately postoperation were measured, and PI-LL mismatch was determined using the age-adjusted thresholds defined in Lafage et al. After propensity score matching, early reoperation rates were compared between the PI-LL mismatch and normal PI-LL cohorts. Early reoperation was defined as symptomatic adjacent segment disease (ASD) requiring reoperation within 2 years of the index surgery. RESULTS: A total of 219 patients were identified. The average age was 59 years of age, with 59.8% female. The PI-LL mismatch cohort (n = 148) was younger (57.5 vs. 63.5 years, P < 0.001) and had a higher proportion of Black patients (31.8% vs. 11.3%, P = 0.001) than the normal PI-LL cohort, respectively. A total of 100 patients in the PI-LL mismatch cohort were propensity score matched to 66 patients in the normal PI-LL cohort, resulting in no difference in age (P = 0.177), sex (P = 0.302), race (P = 0.727), or body mass index (P = 0.892). Using these matched cohorts, the rate of early reoperation for ASD was 8.0% in the PI-LL mismatch cohort and 9.1% in the normal PI-LL cohort (P = 0.805), with a mean time to reoperation of 1.28 and 1.33 years, respectively. CONCLUSIONS: After propensity score matching, PI-LL mismatch was not associated with early reoperation for ASD in patients undergoing 1- to 2-level lumbar fusions for degenerative conditions.
RESUMO
BACKGROUND CONTEXT: Traumatic spinal injuries (TSI) are associated with high morbidity, mortality, and resource utilization. The epidemiology of TSI varies greatly across different countries and regions and is impacted by national income levels, infrastructure, and cultural factors. Further, there may be changes over time. It is essential to investigate TSI to gain useful epidemiologic information. However, there have been no recent studies on trends for TSI in the US, despite the changing population demographics, healthcare policy, and technology. As a result, reexamination is warranted to reflect how the modern era has affected the epidemiology of US spine trauma patients and their management. PURPOSE: To determine epidemiologic trends in traumatic spine injuries over time. STUDY DESIGN/SETTING: Retrospective analysis; level 1 trauma center in the United States. PATIENT SAMPLE: A total of 21,811 patients, between the years of 1996 and 2022, who presented with traumatic spine injury. OUTCOME MEASURES: Age, sex, race, Injury Severity Score, mechanism of injury, injury diagnosis, injury level, rate of operative intervention, hospital length of stay, intensive care unit length of stay, discharge disposition, in-hospital mortality. METHODS: Data was collected from our institutional trauma registry over a 26-year period. Inclusion criteria involved at least one diagnosis of vertebral fracture, spinal cord injury, spinal subluxation, or intervertebral disc injury. Exclusion criteria consisted of patients with no diagnosed spine injury or a diagnosis of strain only. A total of 21,811 patients were included in the analysis. Descriptive statistics were tabulated and ordinary least squares linear regression was conducted for trends analysis. RESULTS: Regression analysis showed a significant upward trend in patient age (+13.83 years, ß=+0.65/year, p<.001), female sex (+2.7%, ß=+0.18%/year, p=.004), falls (+10.5%, ß=+0.82%/year, p<.001), subluxations (+12.8%, ß=+0.35%/year, p<.001), thoracic injuries (+1.5%, ß=+0.28%/year, p<.001), and discharges to subacute rehab (+15.9%, ß=+0.68%/year, p<.001). There was a significant downward trend in motor vehicle crashes (-7.8%, ß=-0.47%/year, p=.016), firearms injuries (-3.4%, ß=-0.19%/year, p<.001), sports/recreation injuries (-2.9%, ß=-0.18%/year, p<.001), spinal cord injuries (-11.25%, ß=-0.37%, p<.001), complete spinal cord injuries (-7.6%, ß=-0.24%/year, p<.001), and discharges to home (+4.5%, ß=-0.27%/year, p=.011). CONCLUSIONS: At our institution, the average spine trauma patient has trended toward older females. Falls represent an increasing proportion of the mechanism of injury, on a trajectory to become the most common cause. With time, there have been fewer spinal cord injuries and a lower proportion of complete injuries. At discharge, there has been a surge in the utilization of subacute rehabilitation facilities. Overall, there has been no significant change in injury severity, rate of operative intervention, length of stay, or mortality.

Revision total hip arthroplasty (THA) is a procedure with many challenges, especially when patients exhibit femoral bone defects. The causes of these defects vary, ranging from removal of prior implants to aseptic loosening. As surgeons navigate these challenges, a reliable surgical system is important. One modular fluted tapered system provides surgeons with tools to address complex hip revision cases. Introduced in 2003, this system has been utilized in over 180,000 procedures, demonstrating its reliability and effectiveness. Previously, the body stem came in sizes 155mm to 235mm. In the discussed case series, we present six distinct patient cases that highlight the advantages and efficacy of a newly introduced modification of the system; that is the use of smaller stemmed components (now 115mm). With each patient presenting unique challenges, we have demonstrated the use of this new short-stem version for multiple applications for various revision scenarios.
RESUMO
BACKGROUND: Elevated body mass index (BMI) increases surgical complications post-total hip arthroplasty (THA). However, the effects of rapid weight loss pre-THA remain unclear. This study evaluated patients who had initial BMIs between 40 and 50, and then achieved a BMI under 35 at various intervals before their THA. Comparisons were made with consistent obese and nonobese groups to understand potential complications. METHODS: Using a national database, we categorized THA patients based on initial BMI and weight loss timing before the surgery. These were contrasted with those maintaining a steady BMI of 20 to 30 or 40 to 50. We monitored outcomes like periprosthetic joint infections (PJI), surgical site infections (SSI), and noninfectious revisions for 2 years postsurgery, incorporating demographic considerations. Statistical analyses utilized Chi-square tests for categorical outcomes and Student's t-tests for continuous variables. RESULTS: Among patients who had a BMI of 45 to 50, weight loss 3 to 9 months presurgery increased PJI risks at 90 days (Odds Ratios [OR]: 2.15 to 5.22, P < .001). However, weight loss a year before the surgery lowered the PJI risk (OR: 0.14 to 0.27, P < .005). Constantly obese patients faced heightened PJI risks 1 to 2 years postsurgery (OR: 1.64 to 1.95, P < .015). Regarding SSI, risks increased with weight loss 3 to 9 months before surgery, but decreased when weight loss occurred a year earlier. In the BMI 40 to 45 group, weight loss 3 to 6 months presurgery showed higher PJI and SSI at 90 days (P < .001), with obese participants consistently at greater risk. CONCLUSIONS: While high BMI poses THA risks, weight loss timing plays a crucial role in postoperative complications. Weight loss closer to the surgery (0 to 9 months) can heighten risks, but shedding weight a year in advance seems beneficial. Conversely, initiating weight loss approximately a year before surgery offers potential protective effects against postoperative issues. This highlights the importance of strategic weight management guidance for patients considering THA, ensuring optimal surgical results and reducing potential adverse outcomes.

INTRODUCTION: Modular fluted, tapered stems provide a reliable treatment for Vancouver B2/B3 fractures. Historically, these patients had weightbearing restrictions postoperatively. Although full immediate postoperative weightbearing may provide benefits in this patient population, stem subsidence is a concern. QUESTIONS/PURPOSES: The objective of this study was to investigate the effect of post-operative weight-bearing status on stem subsidence in patients treated with modular tapered stems for Vancouver B2 and B3 periprosthetic fractures. We sought to answer two questions: (1) Does full immediate postoperative weightbearing after revision total hip arthroplasty for periprosthetic femur fracture lead to increased stem subsidence compared to protected weightbearing? (2) Is there a mortality difference between these two groups of patients with different weightbearing restrictions? METHODS: From 2009 to 2015 all patients who underwent revision for Vancouver B2/B3 fractures were made non-weightbearing (NWB) for six weeks postoperatively. After 2015, immediate weightbearing as tolerated (WBAT) was allowed postoperatively. We compared stem subsidence between immediate postoperative and final radiographs. Additionally, we performed a Kaplan-Meijer analysis with one-year mortality as an endpoint. RESULTS: The final cohort included forty-seven patients with an average follow-up of 254 days. The average stem subsidence was 1.0 mm (95 % CI, 0.5-1.5 mm) in the NWB cohort and 0.3 mm (95 % CI, 0-0.7 mm) in the WBAT cohort (P = 0.10). In our survivorship analysis, we noted no deaths in the WBAT cohort compared to 17 % mortality in the NWB cohort at the one-year timepoint. CONCLUSION: Allowing patients to weight bear immediately after revision does not increase stem subsidence. Further studies are needed to determine whether early weightbearing provides a mortality benefit.

Introduction: Obstructive sleep apnea (OSA) impacts approximately 936 million individuals globally and is known to complicate post-surgical recovery, particularly after total hip arthroplasty (THA). While continuous positive airway pressure (CPAP) is commonly recommended for managing OSA, its effect on THA recovery remains uncertain. The study aimed to assess the impact of CPAP use on post-THA outcomes in patients with OSA, focusing on medical complications and periprosthetic joint infection (PJI) at 90 days and 1 year. Methods: A national, all-payer database was utilized to identify patients undergoing primary THA between 2010 and 2021. Patients with OSA were stratified based on CPAP use through propensity score matching. Three matched groups were formed: OSA without CPAP, OSA with CPAP, and no OSA. Medical and surgical complications were assessed at 90 days and 1 year post-THA. Results: Patients with OSA using CPAP exhibited more baseline comorbidities than those without CPAP. CPAP use was associated with inferior outcomes, including higher odds of PJI, wound complications, and venous thromboembolism at 90 days and 1 year post-THA. These trends were consistent even after adjusting for confounders. Conclusion: CPAP use, indicative of severe OSA, was linked to worse post-THA outcomes, emphasizing the importance of recognizing OSA severity preoperatively. The study does not advocate for or against CPAP use but underscores the heightened risk in this patient population, guiding clinicians in tailoring perioperative strategies and counseling patients about potential risks.
RESUMO
BACKGROUND: Traumatic cervical spinal cord injury (tCSCI) is often a debilitating injury, making early prognosis important for medical and surgical planning. Currently, the best early predictors of prognosis are physical examination, imaging studies, and patient demographics. Despite these factors, patient outcomes continue to vary significantly. The purpose of this study was to evaluate the prognostic value of somatosensory evoked potentials (SSEPs) with functional outcomes in tCSCI patients. METHODS: A retrospective study was conducted on prospectively collected data from 2 academic institutions. Patients 18 years and older who had tCSCI and underwent posterior cervical decompression and stabilization with intraoperative neuromonitoring were reviewed. The outcomes of interest were the American Spinal Injury Association (ASIA) Impairment Scale (AIS) grade and ASIA motor score at follow-up. Outcomes measures were assessed via student t-tests, chi-squared tests, and multivariable regression analysis. RESULTS: A total of 79 patients were included. In complete injuries, detectable lower extremity SSEPs were associated with higher ASIA motor scores at follow-up (P = 0.002), greater increases in ASIA motor scores at follow-up (P = 0.009), and a greater likelihood of clinically important improvement in ASIA motor score (P = 0.024). Incomplete, AIS grade C injuries has higher rates of grade conversion (P = 0.019) and clinically important improvement in ASIA motor score (P = 0.010), compared to AIS grade A or B injuries. CONCLUSIONS: The detection of lower extremity SSEP signals during initial surgical treatment of tCSCI is associated with greater improvement in ASIA motor scores postoperatively. The association is most applicable to patients with complete injury.

BACKGROUND: Studies suggest an increase in the number of combined users of tobacco and cannabis. Therefore, we specifically assessed tobacco, cannabis, and combined users who underwent primary total knee arthroplasty (TKA) to determine 90-day to 2-year: (1) odds of periprosthetic joint infection; (2) odds of revision; and (3) medical complications. METHODS: We queried a national, all payer database of patients undergoing primary TKA between 2010 and 2020. Patients were stratified according to current use of tobacco products (n = 30,000), cannabis (n = 400), or a combination (n = 3,526). These were defined according to International Classification of Disease codes, Ninth and Tenth Editions. Patients were tracked from the 2 years before TKA through 2 years afterwards. A fourth group of TKA recipients who did not have tobacco nor cannabis use was used as a matching cohort. Periprosthetic joint infections (PJIs), revisions, and other medical/surgical complications from 90 days through 2 years were evaluated between these cohorts using bivariate analyses. Multivariate analyses assessed independent risk factors for PJI at 90 days through 2 years, adjusted for patient demographics and health metrics. RESULTS: Combined tobacco and cannabis use were associated with the highest rates of PJI following TKA. The odds of 90-day PJI risk among cannabis, tobacco, and combined users was 1.60, 2.14, and 3.39, respectively, as compared to the matched cohort (P < .001). Co-users had the highest and significantly increased revision odds at 2 years following TKA (odds ratio = 1.52, 95% confidence interval, 1.15 to 2.00). At 1 and 2 years following TKA, cannabis, tobacco, and co-users had higher rates of myocardial infarctions, respiratory failures, surgical site infections, and manipulations under anesthesia when compared to the matched cohort (all P < .001). CONCLUSION: Tobacco and cannabis use before primary TKA demonstrated a synergistic association on PJI risk from 90 days through 2 years. Although the harms of tobacco use are well-known, this additional knowledge about cannabis should be incorporated in the shared decision-making discussions in the pre-operative setting to best prepare for expected risks following primary TKA.

OBJECTIVE: In patients with traumatic cervical spinal cord injury (tCSCI), the potential role of intraoperative neuromonitoring as a prognostic tool has been insufficiently studied. This study aimed to determine if detectable signals during intraoperative neuromonitoring portend a greater likelihood of recovery for patients with tCSCI. METHODS: Patients who underwent decompression and surgical fixation following tCSCI were retrospectively reviewed through previously prospectively collected data from the Surgical Timing in Acute Spinal Cord Injury Study. Improvement in American Spinal Injury Association (ASIA) motor score and ASIA Impairment Scale grade conversion rates at final follow-up were compared between patients with detectable intraoperative neuromonitoring somatosensory evoked potential (SSEP) signals and those without detectable signals. RESULTS: Forty-nine patients had intraoperative neuromonitoring. Patients with incomplete tCSCI had detectable lower extremity SSEPs more often than patients with complete tCSCI (56.3% vs. 23.5%, P = 0.028). There was no difference in detectable upper extremity SSEPs between complete and incomplete tCSCI (65.6% vs. 58.8%, P = 0.638). Of the 17 patients with complete tCSCI, patients with detectable lower extremity SSEPs had ASIA motor scores similar to the nondetectable cohort on admission (21.5 vs. 16.2, P = 0.609) but higher ASIA motor scores at final follow-up (57.5 vs. 27.1, P = 0.041). Of the 32 patients with incomplete spinal cord injury, there was no difference in grade conversion or motor scores between detectable and nondetectable SSEP cohorts. CONCLUSIONS: The presence of upper extremity SSEP signals in patients who present with complete tCSCI portends greater improvement in ASIA motor scores and likelihood of American Spinal Injury Association Impairment Scale grade conversion at final follow-up.

OBJECTIVE: The aim of this study was to compare accuracy of surgical plans generated from in-person and telemedicine evaluations and assess the reasons for surgical plan changes between initial evaluation and surgery. The secondary objective was to assess the effect of changes in surgical planning on postoperative outcomes. METHODS: In this retrospective cohort study, consecutive patients who were evaluated as new patients by orthopaedic spine faculty between 2019 and 2021 were divided by appointment type: telemedicine (n = 39) and in-person (n = 92). Patients were included if the surgeon documented a definitive surgical plan at the initial visit. The primary outcome was change in surgical plan from initial assessment to actual procedure performed. RESULTS: There was no significant difference in the accuracy of initial surgical plans between the telemedicine and in-person cohorts (79.5% vs. 82.6%, P = 0.673). The most common modification in the surgical plan (79%) was change in the number of operated levels, of which 18 of 19 patients had 1 added operated level. Less common reasons were change in approach (13%) and change in procedure (8%). Patients with changes to their surgical plan experienced longer length of stay (3.1 vs. 2.0 days, P = 0.027) than patients with consistent surgical plans. CONCLUSIONS: Telemedicine and in-person evaluations generated similarly accurate surgical plans. Changes to the initial surgical plans most often involved adding operative levels. Our findings show that telemedicine visits are an acceptable option for preoperative assessment to generate surgical plans; however, further research is needed.

PURPOSE: The purpose of this study was to analyze the correlation between baseline depression and anxiety and preoperative functional status in hip arthroscopy patients. METHODS: A prospective, institutional review board-approved orthopaedic registry was used to retrospectively study 104 patients undergoing hip arthroscopy. Enrolled patients were administered baseline questionnaires for Patient-Reported Outcomes Measurement Information System (PROMIS) domains, Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) preoperative expectations, and Numeric Pain Scale (NPS). RESULTS: The average baseline PROMIS Depression and Anxiety scores were 49.9 ± 9.8 and 55.5 ± 9.3, respectively. Bivariate analysis demonstrated that greater baseline PROMIS Anxiety correlated with worse preoperative PROMIS PI (p < 0.001), Fatigue (p < 0.001), Social Satisfaction (p < 0.001), and NPS score (p = 0.013). Bivariate analysis showed that greater PROMIS Depression correlated with worse preoperative PROMIS PF (p = 0.001), PI (p < 0.001), Fatigue (p < 0.001), SS (p < 0.001), and NPS score (p = 0.004). After controlling for confounders, multivariable analysis confirmed increased PROMIS Depression as an independent predictor of worse preoperative PROMIS PF (p = 0.009), MODEMS Expectations (p = 0.025), and NPS score (p = 0.002). Increased PROMIS Anxiety was predictive of worse baseline PROMIS PI (p < 0.001), Fatigue (p < 0.001), and Social Satisfaction (p < 0.001). A previous clinical diagnosis of depression or anxiety was only an independent predictor of worse baseline PROMIS Fatigue (p = 0.002) and was insignificant in all other models. CONCLUSION: Increasing severity of depression and anxiety correlated with and predicted worse functional status at baseline in hip arthroscopy patients. As compared to clinical diagnosis of anxiety and depression, PROMIS metrics have superior utility in recognizing potentially modifiable mental health concerns that predict worse preoperative status. Ultimately, the study identifies an at-risk population undergoing hip arthroscopy that requires particular attention and potential mental health intervention in the preoperative setting.

PURPOSE: As the prevalence of femoro-acetabular impingement syndrome (FAIS) in symptomatic patients who lack evidence of hip osteoarthritis (OA) remains to be described, the purpose of this study was to calculate the prevalence of FAIS in this patient population. METHODS: Libraries of PubMed, Embase, and Ovid were systematically reviewed for all studies between 2009 and 2019, investigating femoro-acetabular impingement and hip pain. Level I-IV studies delineating patients with hip pain who do not have OA (Tonnis or Outerbridge grades < three) were included. Demographics, outcomes, radiographic parameters, and criteria were entered into a meta-analysis to calculate the incidence of FAIS in non-arthritic symptomatic hips. RESULTS: In total, 2264 patients (2758 hips) were included in the pooled analysis. Weighted mean age was 31 years. The incidence of FAIS in patients with no evidence of osteoarthritis but who complain of hip pain is 61% (47.3-74.4%). In total, 1483 hips were diagnosed with FAIS. Of the studies that described the rates of all three of the various subtypes of FAIS in their reports, 37% had a combined-type, 38% had a cam-type, and 25% had a pincer-type FAIS. CONCLUSION: Femoroacetabular impingement should be suspected in 47 to 74% of patients with hip pain and without arthritis. Physicians must maintain a high index of suspicion for FAIS in young patients presenting with hip pain, as FAIS is a common and treatable condition that, if left alone, may lead to hip degeneration.

STUDY DESIGN: Retrospective cohort study. PURPOSE: To determine the effects of massive weight loss on perioperative complications after lumbar fusion surgery (LFS). OVERVIEW OF LITERATURE: Patients who are obese are more likely to experience low back pain, which would require LFS. Nonetheless, they have a higher risk of perioperative complication development compared with individuals who are not obese. METHODS: Patients who underwent LFS at hospitals that participated in the National Surgical Quality Improvement Program database within the United States between 2005 and 2015. Outcomes included 30-day medical complications, surgical complications, and length of stay (LOS). We analyzed a total of 39,742 patients with the use of the International Classification of Disease, ninth revision codes. The patients were categorized in the following two groups: group 1, individuals with a history of massive weight loss within 6 months before LFS, and group 2, individuals without a history of massive weight loss before surgery. Massive weight loss was defined as loss of 10% of total body weight. Patients with a history of malignancy or chronic disease were excluded from the study. Patients in each group were randomly matched based on age, gender, sex, smoking status, and body mass index. Paired two-tailed Student t-tests were used to compare the outcomes. RESULTS: Of the 39,742 patients identified, 129 (0.32%) met the criteria for inclusion in the weight loss group (WL group) and were successfully matched to individuals in the non-weight loss group (non-WL group). Compared with the non-WL group, the WL group had a significantly longer LOS (9.7 vs. 4.0 days, p<0.05), higher surgical site infections (SSIs) (8.0 vs. 3.0, p<0.05), increased number of blood transfusions (40.0 vs. 20.0, p<0.05), and greater deep vein thrombosis (DVTs) (5.0 and 0.00, p<0.05). CONCLUSIONS: On a nationwide scale, rapid weight loss before LFS is associated with a higher rate of postoperative complications, including SSI and DVTs, longer average LOS, and more frequent blood transfusions.
RESUMO
STUDY DESIGN: We performed a comprehensive search of PubMed, MEDLINE, and EMBASE for all English language studies of all levels of evidence pertaining to Spine Patient Outcomes Research Trial (SPORT), in accordance with Preferred Reported Items for Systematic Reviews and Meta-analyses guidelines. OBJECTIVE: We aim to summarize the 10-year clinical outcomes of SPORT and its numerous follow-up studies for degenerative spondylolisthesis. SUMMARY OF BACKGROUND DATA: The SPORT was a landmark randomized control trial including approximately 2500 patients at 13 clinics across the country. SPORT compared surgical and nonoperative management of the three most common spinal pathologies. METHODS: Keywords used in the literature search included SPORT, spine patient outcomes research trial, degenerative spondylolisthesis, and surgical outcomes. RESULTS: The intent-to-treat analysis failed to show a significant difference between patients treated surgically as compared to those treated nonoperatively. However, as-treated analysis revealed statically greater improvements at 6 weeks, 2 years, and 4 years in patients treated surgically. Secondary outcomes such as low back pain, leg pain, stenosis bothersome scales, overall satisfaction with current symptoms, and self-rated progress were also significantly improved in surgical patients. Regardless of the initial grade of listhesis, disk height, or mobility, patients who had surgical treatment improved more in terms of Oswestry Disability Index, bodily pain, physical function, and low back pain bothersomeness scales. Risk of reoperation increased with age, having two or three moderate or severe stenotic levels, pain predominantly localized to the back, no physical therapy, the absence of neurogenic claudication, and greater leg pain scores. Risk of reoperation was not significantly affected by type of surgery performed, smoking, diabetes, obesity, longer duration of symptoms, or workman's compensation. CONCLUSION: Although intent-to-treat analysis failed to show significant differences in patients treated surgically, results of the as-treated analysis determined statically greater improvements in those patients with spondylolisthesis who were treated surgically as compared to those treated nonoperatively. LEVEL OF EVIDENCE: 2.

MINI: We summarized the 10-year outcomes of Spine Patient Outcomes Research Trial for intervertebral disc herniation through a systematic review. The observational cohort 2-year analysis and the as-treated analysis of the randomized control trial at 4 and 8 years showed statistically greater improvements in those patients who were treated surgically. STUDY DESIGN: We performed a comprehensive search of Pubmed, MEDLINE, and EMBASE for English-language studies of all levels of evidence pertaining to SPORT, in accordance with Preferred Reported Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. OBJECTIVE: We aim to summarize the 10-year clinical outcomes of SPORT and its numerous follow-up studies for intervertebral disc herniation. SUMMARY OF BACKGROUND DATA: The Spine Patient Outcomes Research Trial (SPORT) was a landmark study. SPORT compared surgical and nonoperative management of the three most common spinal pathologies. METHODS: Keywords utilized included: SPORT, spine patient outcomes research trial, disc herniation, and surgical outcomes. RESULTS: The observational cohort analysis revealed statically greater improvement in primary outcomes at 3 months and 2 years in patients who had surgery, while analysis of the randomized control trial cohort failed to show a significant difference based on the intent-to-treat principle due to significant patient crossover. However, 4 year and 8 year as-treated analysis showed statistically greater improvements in those patients who were treated surgically. SPORT's subgroup analysis evaluated important factors when considering the treatment of IDH, including patient characteristics, level of herniation, duration of symptoms, recurrence of pain, presence of retrolistheiss, patient functional status, effects of previous treatment with epidural steroid injections and opioid medication, outcomes after incidental durotomy, MRI reader reliability, reoperation rates, and risk factors for reoperation. The clinical impact of SPORT was also investigated and included comparison of SPORT patients to NSQIP patients to determine generalizability, outcome differences in SPORT's surgical center sites, patient preferences, patient expectations, level of education, and effects of watching an evidence-based video. CONCLUSION: Ten years after its inception, SPORT has made strides in standardization and optimization of treatment for spinal pathologies. SPORT has provided clinicians with insight about outcomes of surgical and nonoperative treatment of IDH. Results showed significantly greater improvements in patients treated surgically.

SPORT has provided clinicians with insight about outcomes of surgical and nonoperative treatment of IDH. Results showed significantly greater improvements in patients treated surgically. Level of Evidence: 3.

STUDY DESIGN: We performed a comprehensive search of Pubmed, MEDLINE, and EMBASE for all English-language studies of all levels of evidence pertaining to SPORT, in accordance with Preferred Reported Items for Systematic Reviews and Meta-analayses (PRISMA) guidelines. OBJECTIVE: We aim to summarize the 10-year clinical outcomes of SPORT and its numerous follow-up studies for spinal stenosis. SUMMARY OF BACKGROUND DATA: The Spine Patient Outcomes Research Trial (SPORT) was a landmark randomized control trial including approximately 2,500 patients at 13 clinics across the country. SPORT compared surgical and nonoperative management of the three most common spinal pathologies. METHODS: Keywords utilized in the literature search included: SPORT, spine patient outcomes research trial, spinal stenosis, and surgical outcomes. RESULTS: Surgical intervention showed significantly greater improvement in pain and physical function scales from 6 weeks through 4 years. However, between 4 and 8 years, the difference between the two groups diminished, and the benefits in both groups stabilized. Secondary factors investigated showed that smoking was a confounding variable for treatment benefits and a positive sedimentation sign correlated with a greater surgical treatment effect. Obese patients were found to have higher rates of infection and reoperation and less improvement from baseline function. Risk factors for reoperation included duration of pretreatment symptoms for longer than 12 months, increased age, multiple levels of stenosis, predominant back pain, no physical therapy, greater leg pain, the use of antidepressants and no neurogenic claudication upon enrollment. CONCLUSION: Ten years after its inception, SPORT has made strides in standardization and optimization of treatment for spinal pathologies. SPORT has provided clinicians with insight about outcomes of surgical and nonoperative treatment of spinal stenosis. Results showed significantly greater improvement through 4 year follow up in those patients that received surgical treatment, however the difference between the surgical and nonsurgical groups diminished at 8 year follow up. LEVEL OF EVIDENCE: 3.

Background: There is no consensus regarding how to care for a patient presenting with early isolated incision drainage after thoracolumbar spine surgery. Although drainage is the most common presenting symptom of surgical site infection (SSI), it has low specificity for SSI in the absence of other symptoms. Given that invasive treatment for SSI is costly and high risk, it would be beneficial to determine whether antibiotic treatment alone is sufficient for isolated drainage and what factors predispose to failure of this conservative strategy. Methods: The authors retrospectively reviewed a clinical database of patients who underwent thoracolumbar spine surgery at a single center between 2012-2017. Patients were included if serosanguinous drainage was present within six weeks of surgery without other signs and symptoms of infection such as fever, chills, purulent discharge, fluctuance, wound dehiscence, or erythema. Results: Fifty-eight patients met the study inclusion criteria. After initial conservative management with antibiotics, drainage resolved in 51 patients. The seven patients with drainage that did not resolve were treated with operative surgical washout. Although the groups were similar in most respects, there was a significant difference in the American Society of Anesthesiologists (ASA) score, which is a marker of overall health (surgical group score 2.89 ± 0.33 versus 2.06 ± 0.61; p < 0.0001). In addition, patients with greater estimated blood loss, length of hospital stay, operative time, and spinal levels treated were more likely to require surgical washout, although these differences were not statistically significant. Groups were similar with respect to age, Body Mass Index, smoking status, diabetes mellitus status, revision versus primary surgery, and drainage latency. Conclusion: Most patients who present with isolated serosanguinous incision drainage within six weeks of surgery may be managed successfully using antibiotics only. Patients who fail to respond to conservative therapy have significantly worse general health, as indicated by the ASA score.
