Study Design. Longitudinal Cohort Study. Objective. Determine 1-year patient-reported outcomes associated with preoperative chronic opioid therapy and high-preoperative opioid dosages in patients undergoing elective spine surgery. Summary of Background Data. Back pain is the most disabling condition worldwide and over half of patients presenting for spine surgery report using opioids. Preoperative dosage has been correlated with poor outcomes, but published studies have not assessed the relationship of both preoperative chronic opioids and opioid dosage with patient-reported outcomes. Methods. For patients undergoing elective spine surgery between 2010 and 2017, our prospective institutional spine registry data was linked to opioid prescription data collected from our state's Prescription Drug Monitoring Program to analyze outcomes associated with preoperative chronic opioid therapy and high-preoperative opioid dosage, while adjusting for confounders through multivariable regression analyses. Outcomes included 1-year meaningful improvements in pain, function, and quality of life. Additional outcomes included 1-year satisfaction, return to work, 90-day complications, and postoperative chronic opioid use. Results. Of 2128 patients included, preoperative chronic opioid therapy was identified in 21% and was associated with significantly higher odds (adjusted odds ratio [95% confidence interval]) of not achieving meaningful improvements at 1-year in extremity pain (aOR:1.5 [1.2–2]), axial pain (aOR:1.7 [1.4–2.2]), function (aOR:1.7 [1.4–2.2]), and quality of life (aOR:1.4 [1.2–1.9]); dissatisfaction (aOR:1.7 [1.3–2.2]); 90-day complications (aOR:2.9 [1.7–4.9]); and postoperative chronic opioid use (aOR:15 [11.4–19.7]). High-preoperative opioid dosage was only associated with postoperative chronic opioid use (aOR:4.9 [3–7.9]). Conclusion. Patients treated with chronic opioids prior to spine surgery are significantly less likely to achieve meaningful improvements at 1-year in pain, function, and quality of life; and less likely to be satisfied at 1-year with higher odds of 90-day complications, regardless of dosage. Both preoperative chronic opioid therapy and high-preoperative dosage are independently associated with postoperative chronic opioid use. Level of Evidence: 2
BACKGROUND Emergency department (ED) overuse is a costly and often neglected source of postdischarge resource utilization after spine surgery. Failing to investigate drivers of ED visits represents a missed opportunity to improve the value of care in spine patients. OBJECTIVE To identify the prevalence, drivers, and timing of ED visits following elective spine surgery. METHODS Patients undergoing elective spine surgery for degenerative disease at a major medical center were enrolled in a prospective longitudinal registry. Patient and surgery characteristics, and patient-reported outcomes were recorded at baseline and 3 mo after surgery, along with self-reported 90-d ED visits. A multivariable regression model was used to identify independent factors associated with 90-d ED visits. For a sample of patients presenting to our institution's ED, charts were reviewed to identify the reason and time to ED postdischarge. RESULTS Of 2762 patients, we found a 90-d ED visit rate of 9.4%. One-third of patients presented to our institution's ED and of these, 70% presented due to pain or medical concerns at 9 and 7 d postdischarge, respectively, with 60% presenting outside normal clinic hours. Independent risk factors for 90-d ED visits included younger age, preoperative opioid use, chronic obstructive pulmonary disorder, and more vertebral levels involved. CONCLUSION Nearly 10% of elective spine patients had 90-d ED visits not requiring readmission. Pain and medical concerns accounted for 70% of visits at our center, occurring within 10 d of discharge. This study provides the clinical details and a timeline necessary to guide individualized interventions to prevent unnecessary, costly ED visits after spine surgery.
Study Design. Longitudinal Cohort Study Objective. The aim of this study was to determine whether duration of postoperative opioids is associated with long-term outcomes, and if initial postoperative opioid dosage is associated with opioid cessation after spine surgery. Summary of Background Data. Preoperative opioid use is associated with poor outcomes, but little evidence exists regarding the implications of opioid dosage and duration after spine surgery. Methods. Data from our state's prescription drug database was linked to our prospective clinical spine registry to analyze opioid dispensing and outcomes in elective surgical spine patients between 2010 and 2017. Patients were stratified based on preoperative chronic opioid use and multivariable regression was used to assess associations between duration of postoperative opioids and outcomes at one year, including satisfaction, chronic opioid use, and meaningful improvements in pain, disability, and quality of life. In a secondary aim, a Cox proportional hazards model was used to determine whether initial postoperative opioid dosage was associated with time to opioid cessation. Results. Of 2172 patients included, 35% had preoperative chronic opioid use. In patients without preoperative chronic opioid use, a postoperative opioid duration of 31 to 60 days was associated with chronic opioid use at 1 year (adjusted odds ratio [aOR]: 4.1 [1.7–9.8]) and no meaningful improvement in extremity pain (aOR: 1.8 [1.3–2.6]) or axial pain (aOR: 1.6 [1.1–2.2]); cessation between 61 and 90 days was associated with no meaningful improvement in disability (aOR: 2 [1.3–3]) and dissatisfaction (aOR:1.8 [1–3.1]). In patients with preoperative chronic opioid use, postoperative opioids for ≥90 days was associated with dissatisfaction. Cox regression analyses showed lower initial postoperative opioid dosages were associated with faster opioid cessation in both groups. Conclusion. Our results suggest that a shorter duration of postoperative opioids may result in improved 1-year patient-reported outcomes, and that lower postoperative opioid dosages may lead to faster opioid cessation.

Background: Musculoskeletal infection is a major cause of morbidity in the pediatric population. Despite the canonical teaching that an irritable joint and signs of infection likely represent an infected joint space, recent evidence in the pediatric hip has demonstrated that alternative diagnoses are equally or more likely and that combinations of pathologies are common. The knee is the second most commonly infected joint in children, yet there remains a paucity of available data regarding the epidemiology and workup of the infected pediatric knee. The authors hypothesize that there is heterogeneity of pathologies, including combinations of pathologies, that presents as a potentially infected knee in a child. The authors aim to show the utility of magnetic resonance imaging and epidemiologic and laboratory markers in the workup of these patients. Methods: A retrospective review of all consults made to the pediatric orthopaedic surgery team at a single tertiary care center from September 2009 through December 2015 regarding a concern for potential knee infection was performed. Excluded from the study were patients with penetrating trauma, postoperative infection, open fracture, no C-reactive protein (CRP) within 24 hours of admission, sickle cell disease, an immunocompromised state, or chronic osteomyelitis. Results: A total of 120 patients were analyzed in this study. There was marked variability in pathologies. Patients with isolated osteomyelitis or osteomyelitis+septic arthritis were older, had an increased admission CRP, were more likely to be infected with Staphylococcus aureus, required an increased duration of antibiotics, and had an increased incidence of musculoskeletal complications than patients with isolated septic arthritis. Conclusions: When considering a child with an irritable knee, a heterogeneity of potential underlying pathologies and combinations of pathologies are possible. Importantly, the age of the patient and CRP can guide a clinician when considering further workup. Older patients with a higher admission CRP value warrant an immediate magnetic resonance imaging, as they are likely to have osteomyelitis, which was associated with worse outcomes when compared with patients with isolated septic arthritis. Level of Evidence: Level III—retrospective research study.
Study Design: Retrospective Cohort. Objective: Establish 1-year patient-reported outcomes after spine surgery for symptomatic pseudarthrosis compared with other indications. In the subgroup of pseudarthrosis patients, describe preexisting metabolic and endocrine-related disorders, and identify any new diagnoses or treatments initiated by an endocrine specialist. Summary of Background: Despite surgical advances in recent decades, pseudarthrosis remains among the most common complications and indications for revision after fusion spine surgery. A better understanding of the outcomes after revision surgery for pseudarthrosis and risk factors for pseudarthrosis are needed. Methods: Using data from our institutional spine registry, we retrospectively reviewed patients undergoing elective spine surgery between October 2010 and November 2016. Patients were stratified by surgical indication (pseudarthrosis vs. not pseudarthrosis), and 1-year outcomes for satisfaction, disability, quality of life, and pain were compared. In a descriptive subgroup analysis of pseudarthrosis patients, we identified preexisting endocrine-related disorders, frequency of endocrinology referral, and any new diagnoses and treatments initiated through the referral. Results: Of 2721 patients included, 169 patients underwent surgery for pseudarthrosis. No significant difference was found in 1-year satisfaction between pseudarthrosis and nonpseudarthrosis groups (77.5% vs. 83.6%, respectively). A preexisting endocrine-related disorder was identified in 82% of pseudarthrosis patients. Endocrinology referral resulted in a new diagnosis or treatment modification in 58 of 59 patients referred. The most common diagnoses identified included osteoporosis, vitamin D deficiency, diabetes, hyperlipidemia, sex-hormone deficiency, and hypothyroidism. The most common treatments initiated through endocrinology were anabolic agents (teriparatide and abaloparatide), calcium, and vitamin D supplementation. Conclusions: Patients undergoing revision spine surgery for pseudarthrosis had similar 1-year satisfaction rates to other surgical indications. In conjunction with a bone metabolic specialist, our descriptive analysis of endocrine-related disorders among patients with a pseudarthrosis can guide protocols for workup, indications for endocrine referral, and guide prospective studies in this field.
