RESUMO
PURPOSE: Geographic access to physicians has been shown to be unevenly distributed in the USA, with those in closer proximity having superior outcomes. The purpose of this study was to describe how geographic access to pediatric neurosurgeons varies across socioeconomic and demographic factors. METHODS: Actively practicing neurosurgeons were identified by matching several registries and membership logs. This data was used to find their primary practice locations and the distance the average person in a county must travel to visit a surgeon. Counties were categorized into "surgeon deserts" and "surgeon clusters," which were counties where providers were significantly further or closer to its residents, respectively, compared to the national average. These groups were also compared for differences in population characteristics using data obtained from the 2020 American Community Survey. RESULTS: A total of 439 pediatric neurosurgeons were identified. The average person in a surgeon desert and cluster was found to be 189.2 ± 78.1 miles and 39.7 ± 19.6 miles away from the nearest pediatric neurosurgeon, respectively. Multivariate analyses showed that higher Rural-Urban Continuum (RUC) codes (p < 0.001), and higher percentages of American Indian (p < 0.001) and Hispanic (p < 0.001) residents were independently associated with counties where the average person traveled significantly further to surgeons. CONCLUSION: Patients residing in counties with greater RUC codes and higher percentages of American Indian and Hispanic residents on average need to travel significantly greater distances to access pediatric neurosurgeons.

BACKGROUND CONTEXT: Postoperative infection after spinal deformity correction in pediatric patients is associated with significant costs. Identifying risk factors associated with postoperative infection would help surgeons identify high-risk patients that may require interventions to minimize infection risk. PURPOSE: To investigate risk factors associated with 30-day postoperative infection in pediatric patients who have received posterior arthrodesis for spinal deformity correction. STUDY DESIGN/SETTING: Retrospective review of prospectively collected data. PATIENT SAMPLE: The National Surgical Quality Improvement Program Pediatric database for years 2016-2021 was used for this study. Patients were included if they received posterior arthrodesis for scoliosis or kyphosis correction (CPT 22,800, 22,802, 22,804). Anterior only approaches were excluded. OUTCOME MEASURES: TThe outcome of interest was 30-day postoperative infection. METHODS: Patient demographics and outcomes were analyzed using descriptive statistics. Multivariable logistic regression analysis using likelihood ratio backward selection method was used to identify significant risk factors for 30-day infection to create the Pediatric Scoliosis Infection Risk Score (PSIR Score). ROC curve analysis, predicted probabilities, and Hosmer Lemeshow goodness-of-fit test were done to assess the scoring system on a validation cohort. RESULTS: A total of 31,742 patients were included in the study. The mean age was 13.8 years and 68.7% were female. The 30-day infection rate was 2.2%. Reoperation rate in patients who had a post-operative infection was 59.4%. Patients who had post-operative infection had a higher likelihood of non-home discharge (X2 = 124.8, p < 0.001). In our multivariable regression analysis, high BMI (OR = 1.01, p < 0.001), presence of open wound (OR = 3.18, p < 0.001), presence of ostomy (OR = 1.51, p < 0.001), neuromuscular etiology (OR = 1.56, p = 0.009), previous operation (OR = 1.74, p < 0.001), increasing ASA class (OR = 1.43, p < 0.001), increasing operation time in hours (OR = 1.11, p < 0.001), and use of only minimally invasive techniques (OR = 4.26, p < 0.001) were associated with increased risk of 30-day post-operative infection. Idiopathic etiology (OR = 0.53, p < 0.001) and intraoperative topical antibiotic use (B = 0.71, p = 0.003) were associated with reduced risk of 30-day postoperative infection. The area under the curve was 0.780 and 0.740 for the derivation cohort and validation cohort, respectively. CONCLUSIONS: To our knowledge, this is the largest study of risk factors for infection in pediatric spinal deformity surgery. We found 5 patient factors (BMI, ASA, osteotomy, etiology, and previous surgery, and 3 surgeon-controlled factors (surgical time, antibiotics, MIS) associated with risk. The Pediatric Scoliosis Infection Risk Score (PSIR) Score can be applied for risk stratification and to investigate implementation of novel protocols to reduce infection rates in high-risk patients.
RESUMO
For diverse procedures, sizable geographic variation exists in rates and outcomes of surgery, including for degenerative lumbar spine conditions. Little is known about how surgeon training and experience are associated with surgeon-level variations in spine surgery practice and short-term outcomes. This retrospective observational analysis characterized variations in surgical operations for degenerative lumbar scoliosis or spondylolisthesis, two common age-related conditions. The study setting was two large spine surgery centers in one region during 2017-19. Using data (International Classification of Diseases-10th edition and current procedural terminology codes) extracted from electronic health record systems, we characterized surgeon-level variations in practice (use of instrumented fusion - a more extensive procedure that involves device-related risks) and short-term postoperative outcomes (major in-hospital complications and readmissions). Next, we tested for associations between surgeon training (specialty and spine fellowship) and experience (career stage and operative volume) and use of instrumented fusion as well as outcomes. Eighty-nine surgeons performed 2481 eligible operations. For the study diagnoses, spine surgeons exhibited substantial variation in operative volume, use of instrumented fusion, and postoperative outcomes. Among surgeons above the median operative volume, use of instrumented fusion ranged from 0% to >90% for scoliosis and 9% to 100% for spondylolisthesis, while rates of major in-hospital complications ranged from 0% to 25% for scoliosis and from 0% to 14% for spondylolisthesis. For scoliosis, orthopedic surgeons were more likely than neurosurgeons to perform instrumented fusion for scoliosis [49% vs. 33%, odds ratio (OR) = 2.3, 95% confidence interval (95% CI) 1.3-4.2, P-value = .006] as were fellowship-trained surgeons (49% vs. 25%, OR = 3.0, 95% CI 1.6-5.8; P = .001). Fellowship-trained surgeons had lower readmission rates. Surgeons with higher operative volumes used instrumented fusion more often (OR = 1.1, 95% CI 1.0-1.2, P < .05 for both diagnoses) and had lower rates of major in-hospital complications (OR = 0.91, 95% CI 0.85-0.97; P = .006). Surgical practice can vary greatly for degenerative spine conditions, even within the same region and among colleagues at the same institution. Surgical specialty and subspecialty, in addition to recent operative volume, can be linked to variations in spine surgeons' practice patterns and outcomes. These findings reinforce the notion that residency and fellowship training may contribute to variation and present important opportunities to optimize surgical practice over the course of surgeons' careers. Future efforts to reduce unexplained variation in surgical practice could test interventions focused on graduate medical education. Graphical Abstract.

OBJECTIVE: Pulmonary function can be impaired in patients with adolescent idiopathic scoliosis (AIS). Maximal voluntary ventilation (MVV) has been shown to be more strongly correlated with major coronal curve, and a more easily obtained measurement of pulmonary function, than forced vital capacity (FVC). We evaluated changes in pulmonary function using these 2 measures in patients with AIS in relation to changes in major coronal curves over time. METHODS: Forty-seven patients with AIS with thoracic curves ≥10 degrees performed pulmonary function tests using the Carefusion MicroLoop Spirometer at enrollment and 1 year later. Major coronal curve worsening >5 degrees was considered curve progression. RESULTS: At enrollment, 47 patients had a mean major coronal curve of 38 degrees (range: 10 to 76 degrees). One year later, 17 patients had undergone posterior spinal fusion, 9 had curve progression >5 degrees, and 21 had no progression. MVV and major coronal curve were negatively correlated (r = -0.36, P = 0.01) at enrollment. After fusion, the major coronal curve improved by a mean of 41 degrees, and MVV improved by 23% (P < 0.01), but FVC did not improve significantly (6%, P = 0.29). In stable curves, MVV improved 12% (P = 0.01) and FVC improved 9% (P = 0.007). In patients without surgery whose curves progressed an average of 11 degrees, there was no significant change in MVV or FVC (P > 0.44). CONCLUSION: This is the first study using office-based spirometry in an orthopaedic clinic showing improved pulmonary function with posterior spinal fusion and growth in patients with AIS. It is notable that MVV improved after spinal fusion, but FVC did not, as MVV appears to be a more sensitive measurement for the assessment of pulmonary function in these patients. LEVEL OF EVIDENCE: Level II.

BACKGROUND: Children with neuromuscular early onset scoliosis (EOS) receive numerous radiographic studies both from orthopaedic and other specialties. Ionizing radiation doses delivered by computed tomography (CT) are reportedly 100 times higher than conventional radiography. The purpose of this study was to evaluate the number of radiographic studies ordered for neuromuscular EOS patients during their care. METHODS: Retrospective review at a tertiary children's hospital from January 2010 to June 2021 included all patients with neuromuscular EOS followed by an orthopaedic specialist for a minimum of 3 years. Patients were excluded if the majority of their nonorthopaedic care was provided by outside institutions. RESULTS: Eighteen patients met inclusion criteria with mean follow up of 6.4±2.3 years. A total of 1312 plain radiographs and 35 CT scans were performed. Of the plain radiographs, 34.7% were ordered by orthopaedic providers and 65.3% (857/1312) were ordered by other providers. Of the CT scans, 4 were ordered by orthopaedic providers, while 88.5% (21/35) were ordered by other providers. An average of 74.7 (range: 29 to 124) radiographs and 1.9 (range: 0 to 9) CT scans ordered over the course of each patient's treatment for an average of 13.0±6.0 radiographs and 0.3 CT scans per year. CONCLUSIONS: With an average of 75 radiographs and 1.9 CT scans performed per patient, consideration for steps to limit exposure to ionizing radiation should be made a particularly high priority in this unique subset of patients. This requires interdisciplinary coordination as 65% of the radiographs and over 80% of the CT scans were ordered by nonorthopaedic providers. LEVEL OF EVIDENCE: Level III.

INTRODUCTION: After discontinuation of growth-friendly (GF) surgery for early onset scoliosis, patients are termed graduates: they undergo a spinal fusion, are observed after final lengthening with GF implant maintenance, or are observed after GF implant removal. The purpose of this study was to compare the rates of and reasons for revision surgery in two cohorts of GF graduates: before or after 2 years of follow-up from graduation. METHODS: A pediatric spine registry was queried for patients who underwent GF spine surgery with a minimum of 2 years of follow-ups after graduation by clinical and/or radiographic evidence. Scoliosis etiology, graduation strategy, number of, and reasons for revision surgery were queried. RESULTS: There were 834 patients with a minimum of 2-year follow-up after graduation who were analyzed. There were 241 (29%) congenital, 271 (33%) neuromuscular, 168 (20%) syndromic, and 154 (18%) idiopathic. 803 (96%) had traditional growing rod/vertical expandable titanium rib as their GF construct and 31 (4%) had magnetically controlled growing rod. Five hundred ninety-six patients (71%) underwent spinal fusion at graduation, 208 (25%) had GF implants retained, and 30 (4%) had GF implants removed.In the entire cohort, there were 108/834 (13%) patients who underwent revision surgery. Of the revisions, 71/108 (66%) occurred as acute revisions (ARs) between 0 and 2 years from graduation (mean 0.6 y), and the most common AR indication was infection (26/71, 37%). The remaining 37/108 (34%) patients underwent delayed revision (DR) surgery >2 years (mean 3.8 y) from graduation, and the most common DR indication was implant issues (17/37, 46%).Graduation strategy affected revision rates. Of the 596 patients with spinal fusion as a graduation strategy, 98/596 (16%) underwent revision, compared with only 8/208 (4%) patients who had their GF implants retained, and 2/30 (7%) that had their GF implants removed ( P ≤ 0.001).A significantly higher percentage of the ARs had a spinal fusion as the graduation strategy (68/71, 96%) compared with 30/37 DRs, (81%, P = 0.015). In addition, the 71 patients who underwent AR undergo more revision surgeries (mean: 2, range: 1 to 7) than 37 patients who underwent DR (mean: 1, range: 1 to 2) ( P = 0.001). CONCLUSION: In this largest reported series of GF graduates to date, the overall risk of revision was 13%. Patients who undergo a revision at any time, as well as ARs in particular, are more likely to have a spinal fusion as their graduation strategy. Patients who underwent AR, on average, undergo more revision surgeries than patients who underwent DR. LEVEL OF EVIDENCE: Level III, comparative.

AIM: To develop and validate a risk calculator based on preoperative factors to predict the probability of surgical site infection (SSI) in patients with cerebral palsy (CP) undergoing spinal surgery. METHOD: This was a multicenter retrospective cohort study of pediatric patients with CP who underwent spinal fusion. In the development stage, preoperative known factors were collected, and a risk calculator was developed by comparing multiple models and choosing the model with the highest discrimination and calibration abilities. This model was then tested with a separate population in the validation stage. RESULTS: Among the 255 patients in the development stage, risk of SSI was 11%. A final prediction model included non-ambulatory status (odds ratio [OR] 4.0), diaper dependence (OR 2.5), age younger than 12 years (OR 2.5), major coronal curve magnitude greater than 90° (OR 1.3), behavioral disorder/delay (OR 1.3), and revision surgery (OR 1.3) as risk factors. This model had a predictive ability of 73.4% for SSI, along with excellent calibration ability (p = 0.878). Among the 390 patients in the validation stage, risk of SSI was 8.2%. The discrimination of the model in the validation phase was 0.743 and calibration was p = 0.435, indicating 74.3% predictive ability and no difference between predicted and observed values. INTERPRETATION: This study provides a risk calculator to identify the risk of SSI after spine surgery for patients with CP. This will allow us to enhance decision-making and patient care while providing valid hospital comparisons, public reporting mechanisms, and reimbursement determinations.

Most orthopaedic surgeons do not have formal training in business education. We have learned that success comes to those who study hard, choose the correct answer on multiple-choice tests, and focus on patient care and operating. In contrast, business school graduates learned that success comes to those who apply interpersonal skills to build relationships and trust, in addition to taking risks. Medical school and business school teach one to confront the "real world" with quite a different perspective. In this manuscript, we will touch on a few things that we can learn from business school graduates.

BACKGROUND: Facet fractures have been reported in a total of 6 young athletes in 4 previous publications. These injuries were not diagnosed on magnetic resonance imaging (MRI) or radiographs, and were identified on computed tomography (CT). Our purpose was to report a series of athletes with operatively managed facet fractures. This may be an under-recognized diagnosis. METHODS: Retrospective review of pediatric patients with operatively managed isolated lumbar or sacral facet fractures from 3 tertiary pediatric hospitals from 2014 to 2019. Clinical records and imaging studies were reviewed. RESULTS: Ten patients with symptomatic lumbar or sacral facet fractures met inclusion criteria (mean age at presentation; 13.3±2.1 years, 70% Female). All patients reported competitive participation in sports. On physical examination, 10/10 (100%) of patients had lower back pain that was exacerbated with lumbar spine extension. Limited CT scans demonstrated facet fractures in 10/10 (100%) patients not detected on plain film or MRI. All patients experienced significant relief of pain following excision of the facet fracture fragment. At time of first postoperative visit, 9/10 (90%) patients were pain free while one had generalized back pain thought to be related to fibromyalgia and not facet pathology. At time of last follow-up, 2/10 (20%) of patients reported nonspecific back pain that was not localized in the area of the facet fracture, while 80% (8/10) remained pain free. All patients 100% (10/10) returned to full participation to sports. There were no complications noted in this series. Average follow-up was 27 months (range: 1 to 68 mo). CONCLUSIONS: Athletes with localized back pain exacerbated by spine extension may have a facet fracture. As facet fractures are usually not identified with radiographs or MRI, a limited CT scan should be considered in the evaluation of pediatric athletes with localized back pain exacerbated by extension. In this series, surgical excision of facet fracture fragments was safe and provided predictable pain relief.

BACKGROUND: The proximal femur is a common location for pathologic fractures in children, yet there is little published information regarding this injury. The purpose of this study was to investigate the outcomes of pediatric pathologic proximal femur fractures due to benign bone tumors. METHODS: A retrospective review of patients treated for pathologic proximal femur fractures from 2004 to 2018 was conducted. Inclusion criteria were age below 18 years and pathologic proximal femur fracture secondary to a benign bone tumor. Patients were excluded if they had <1 year of follow-up. Medical charts and serial radiographs were reviewed for fracture classification, underlying pathology, treatment, complications, and time to fracture healing. RESULTS: A total of 14 patients were included. Mean age was 6±3 (3 to 11) years, and mean follow-up was 44±21 (22 to 86) months. Index treatment was spica casting in 9/14 (68%) patients, while 5/14 (32%) were treated with internal fixation. Of the 9 patients initially treated with casting, 22% (2/9) required repeat spica casting at a mean of 0.6 months after index treatment, 67% (6/9) required internal fixation at a mean of 20.3 months after index treatment, and 11% (1/9) did not require revision treatment. Eighty-eight percent (8/9) of patients treated with casting required revision treatment compared with 40% (2/5) of those treated with internal fixation (P=0.05). Nonunion occurred after 1 refracture, malunion with coxa vara occurred in 2 fractures, and the remaining 11/14 (84%) fractures had a union at a mean of 4.9±3.0 months All cases of malunion occurred in patients initially treated nonoperatively. There were 19 distinct complications in 10/14 (71%) patients. The incidence of any revision surgery was 64% (9/14). CONCLUSIONS: In this series, pediatric pathologic proximal femur fractures demonstrated prolonged time to union, high incidence of revision surgery (64%), and substantial complication rate (71%). In children with pathologic proximal femur fractures, treatment with internal fixation is recommended as this series showed a 78% failure rate of initial conservative management. LEVEL OF EVIDENCE: Level IV.

BACKGROUND: The outcomes of congenital scoliosis (CS) patients undergoing hemivertebra (HV) resection surgery with a 2-level fusion versus a >2-level fusion are unclear. We hypothesized that CS patients undergoing HV resection and a >2-level fusion have decreased curve progression and reoperation rates compared with 2-level fusions. METHODS: Retrospective review of prospectively collected data from a multicenter scoliosis database. Fifty-three CS patients (average age 4.5, range 1.2 to 10.9 y) at index surgery were included. Radiographic and surgical parameters, complications, as well as revision surgery rates were tracked at a minimum of 2-year follow-up. RESULTS: Twenty-six patients had a 2-level fusion while 27 patients had a >2-level fusion with similar age and body mass index between groups. The HV was located in the lumbar spine for 69% (18/26) 2-level fusions and 30% (8/27) >2-level fusions ( P =0.006). Segmental HV scoliosis curve was smaller in 2-level fusions compared to >2-level fusions preoperatively (38 vs. 50 degrees, P =0.016) and at follow-up (25 vs. 34 degrees, P =0.038). Preoperative T2-T12 (28 vs. 41 degrees, P =0.013) and segmental kyphosis (11 vs. 23 degrees, P =0.046) were smaller in 2-level fusions, but did not differ significantly at postoperative follow-up (32 vs. 39 degrees, P =0.22; 13 vs. 11 degrees, P =0.64, respectively). Furthermore, the 2 groups did not significantly differ in terms of surgical complications (27% vs. 22%, P =0.69; 2-level fusion vs. >2-level fusion, respectively), unplanned revision surgery rate (23% vs. 22%, 0.94), growing rod placement or extension of spinal fusion (15% vs. 15%, P =0.95), or health-related quality of life per the EOS-Questionnaire 24 (EOSQ-24). Comparison of patients with or without the need for growing rod placement or posterior spinal fusion revealed no significant differences in all parameters analyzed. CONCLUSIONS: Two-level and >2-level fusions can control congenital curves successfully. No differences existed in curve correction, proximal junctional kyphosis or complications between short and long-level fusion after HV resection. Both short and long level fusions are viable options and generate similar risk of revision. The decision should be individualized by patient and surgeon.

BACKGROUND: It is unclear whether traditional growing rod (TGR) treatment outcomes vary by early-onset scoliosis (EOS) subtype. The goal of this study was to compare radiographic outcomes and complications of TGR treatment by EOS subtype. METHODS: We queried an international database of EOS patients from 20 centers to identify "graduates" who had (1) undergone primary TGR treatment from 1993 to 2014; (2) completed TGR treatment; and (3) had an uneventful clinical examination within 6 months after completion of TGR treatment with no anticipated further intervention. We included 202 patients in 4 etiologic subgroups: neuromuscular (n=65), syndromic (n=57), idiopathic (n=52), and congenital (n=28). Mean age at surgery was 7.1 years (range, 1.6 to 14.9 y); mean duration of follow-up was 8 years (range, 2 to 18.6 y). The groups did not differ by mean age, body mass index, sex, number of lengthenings, or duration of follow-up. The following preoperative differences were significant: (1) greater mean major curve in the neuromuscular versus idiopathic subgroup; (2) shorter spinal height (T1-S1) in the congenital versus idiopathic subgroup; and (3) smaller proportion of ambulatory patients in the neuromuscular subgroup versus all other subgroups. RESULTS: We found no significant differences among subgroups in mean major curve correction or changes in thoracic height (T1-T12), spinal height, or global kyphosis at any point. Rates of deep surgical site infection, implant-related complications, and neurological complications were not different among subgroups. The medical complication rate was significantly lower in the idiopathic group compared with the other groups. CONCLUSIONS: Major curve correction and spinal and thoracic height increases did not differ significantly at any point by EOS subtype. Rates of deep surgical site infection, implant-related complications, and neurological complications did not differ by subtype. Except for the lower rate of medical complications in the idiopathic group, our findings suggest that, after TGR treatment, patients can expect similar outcomes regardless of their EOS subtype. LEVEL OF EVIDENCE: Level III, therapeutic.

PURPOSE: To investigate the risk and predictive factors of junctional issues after conversion from Traditional growing rod (TGR) to definitive spinal fusion in Early-onset scoliosis (EOS). METHODS: Retrospective review of a multicenter EOS database. TGR patients who received final fusion with at least two-year follow-up were included. Proximal (PJA) and Distal junctional angles (DJA) on pre-final fusion, post-final fusion (within one year of surgery), and at latest follow-up were measured on lateral upright spinal radiographs. Differences in values among designated time points and predictive factors of junctional issues were evaluated statistically. RESULTS: Forty-six of 251 patients (28 females, 18 males and mean age at final fusion: 12 ± 2 [9-17] years) met the inclusion criteria. Mean follow-up between first postoperative measurement and latest follow-up was 49 ± 22 (24-112) months. No statistical differences in PJA and DJA values were available at pre-fusion, first post-fusion, or latest follow-up (p = 0.827, p = 0.076). Fifty percent of patients had extension of TGR instrumentation at fusion, either proximal or distal. No factor including sex and etiology, lumbar lordosis, thoracic kyphosis, major curve magnitude, PJA, and DJA at pre-fusion was found to be a predictive issue for extension of index TGR instrumentation, except the history of at least one implant-related complication during the period from index surgery to the definitive fusion. CONCLUSION: PJA and DJA remained stable when transitioning from TGR to final posterior spinal fusion. But 50% of patients had extension of construction at fusion, either proximal or distal.

BACKGROUND: There is no evidence-based consensus on the risk factors for concomitant osteomyelitis and septic arthritis. The purpose of this study was to investigate clinical parameters predictive of concomitant osteomyelitis in children with septic arthritis. METHODS: A retrospective review was conducted on patients with septic arthritis with magnetic resonance imaging (MRI) between January 2004 and October 2016 at a tertiary care pediatric hospital. Medical charts were reviewed for information including symptoms, diagnosis of osteomyelitis, serum laboratory studies, joint fluid analyses, imaging results, and treatment. Positive diagnosis of osteomyelitis was defined as a hyperintense signal of osseous structures on T2-weighted MRI consistent with infection per attending pediatric radiologist final read. RESULTS: A total of 71 patients with 73 septic joints were included. The mean age was 6±4 (0.1 to 17) years and the mean follow-up was 14.9±24.1 (1.0 to 133.1) months. Septic arthritis with concomitant osteomyelitis occurred in 43 of 71 (61%) patients, whereas 28 of 71 (39%) patients had septic arthritis alone. Inflammatory markers such as white blood cell count, erythrocyte sedimentation rate, and C-reactive protein on admission were not associated with concomitant osteomyelitis. Multivariate logistic regression revealed that positive joint fluid bacterial culture (P=0.021) and pain for >4 days before admission (P=0.004) are independent risk factors for concomitant osteomyelitis in children with septic arthritis. Among the 24 septic arthritis patients with pain for >4 days before presentation, 96% (23/24) had concomitant osteomyelitis, whereas 43% (20/47) of patients with pain for ≤4 days had concomitant osteomyelitis. CONCLUSION: Pain for >4 days before presentation is an independent predictor of osteomyelitis in children with septic arthritis. In pediatric septic arthritis, MRI should be considered, particularly in patients presenting with pain for >4 days as 96% of these patients had concomitant osteomyelitis.

BACKGROUND: Methylnaltrexone, a peripheral opioid antagonist, is used to decrease opioid-induced constipation; however, there is limited evidence for its use in children. The primary objective of the study is to assess the efficacy of per os (PO) methylnaltrexone in inducing bowel movements (BMs) in patients with adolescent idiopathic scoliosis who underwent a posterior spinal fusion and instrumentation (PSFI). Secondary outcomes include hospital length of stay, postoperative pain scores, and postoperative opioid usage. METHODS: Retrospective chart review identified all adolescent idiopathic scoliosis patients above 10 years of age who underwent PSFI with a minimum of 24 hours of postoperative opioid analgesia after the initiation of the new bowel regimen protocol. The bowel regimen included daily administration of PO methylnaltrexone starting on postoperative day 1 until BM is achieved. A case-matched cohort was obtained with patients who did not receive PO methylnaltrexone and otherwise had the same bowel function regimen. Case-matched controls were also matched for age, sex, body mass index, and curve severity. t Tests and Pearson χ2 tests were used for statistical analysis. RESULTS: Fifty-two patients received oral methylnaltrexone (14±2.6 y) and 52 patients were included in the case-matched control group (14±2.1 y). The methylnaltrexone group had a significantly shorter hospital length of stay (3.09±0.66) compared with controls (3.69±0.80) (P<0.01). 59% (31 of 52) of the methylnaltrexone group had a BM by postoperative day postoperative day 2, compared with 30% (16 of 52) of the control group (P<0.01). In the methylnaltrexone group, 44% (23 of 52) of the patients required a Dulcolax (bisacodyl) suppository and 11% (6 of 52) required an enema, compared with 50% (26 of 52) and 33% (12 of 52) of the control group respectively (P=0.43 and 0.12). In addition, significantly less patients had abdominal distension during their postoperative stay in the methylnaltrexone group (17%, 9 of 52) compared with the control group (40%, 21 of 52) (P<0.01). There was no significant difference in self-reported average FACES pain score (P=0.39) or in opioid morphine equivalents required per hour (P=0.18). CONCLUSIONS: Patients who received PO methylnaltrexone after PSFI had decreased length of stay and improved bowel function. Administration of methylnaltrexone did not increase maximum self-reported FACES pain values or opioid consumption compared with controls. The use of oral methylnaltrexone after PSFI reduces postoperative constipation, which has implications for reducing hospital length of stay and overall morbidity. LEVEL OF EVIDENCE: Level III-retrospective comparative study.
RESUMO
BACKGROUND: Tension band plating for temporary hemiepiphysiodesis has been reported by several authors as simple and effective for treating angular deformities of the lower limb. Anecdotally, patients have reported higher pain levels than expected given the small size of incision and relatively minimal amount of dissection, and we sought to investigate this further. METHODS: Patients 16 years old or less with lower extremity angular deformities or limb length inequality were prospectively enrolled before tension band plating from 2 pediatric institutions from July 2016 to December 2018. Participants completed postoperative questionnaires regarding their pain and activity level. Pain was assessed using the FACES Pain Scale. Patients were included if they completed the 1 month survey. RESULTS: Of the 48 patients that met inclusion criteria (mean age at surgery: 13.1 y; range: 7 to 16 y), 39 patients completed the survey at 3 months postoperatively. There was a significant change in pain level between 1 week and 1 month postoperatively (P<0.001). Eighty-three percent (34/41) of patients were still taking pain medication at 1 week, which decreased to 38% (18/48) at 1 month. At 3 months, 21% (8/39) patients reported they were still using pain medication. At 1 month, 65% of patients (31/48) had not returned to their prior activity level. Of the 39 patients who played sports, 59% (23/39) still had not fully returned to sports at 1 month. CONCLUSION: At 1 month following tension band plating, 65% of patients had not returned to their preoperative activity level, and 38% were taking pain medications. Although the tension band plate and surgical incision is small in size, patients and parents should be counseled that there are significant activity limitations and pain levels for a month or longer in many patients. LEVEL OF EVIDENCE: Level II.

BACKGROUND: Parental mental status and behavior may influence postoperative recovery and the use of pain medication. The purpose of this study is to identify if parents with high anxiety are associated with prolonged narcotic use in adolescent patients following posterior spinal fusion surgery. Prolonged narcotic use in this study was defined as opioid use at their first postoperative visit. METHODS: AIS patients age 11 to 20 years undergoing posterior spinal fusion and a parent were prospectively enrolled. At the preoperative appointment, patients completed the Spence Children's Anxiety Scale and parents completed the State-Trait Anxiety Inventory. High parental anxiety was defined as 1 SD above the normative mean. At the first postoperative visit, patients were asked about medication use. RESULTS: A total of 58 patients (49 females and 9 males) were enrolled. Overall, 29% (17/58) of parents had a high general anxiety trait on the State-Trait Anxiety Inventory and 71% (41/58) had normal general anxiety. Of the patients whose parents had high general anxiety, 47% (8/17) were still taking narcotics at their first postoperative visit compared with 20% (8/41) of patients with normal anxiety parents (P=0.03). CONCLUSIONS: Patients with high general anxiety parents were more than twice as likely to still be on narcotics at their first postoperative visit. This information can be used to counsel families on the impact of anxiety on narcotic usage. LEVEL OF EVIDENCE: Level II-prognostic studies-investigating the effect of a patient characteristic on the outcome of the disease.

BACKGROUND: To prospectively evaluate a displacement-based classification system and an outcome-derived algorithm in the treatment of children with lateral condyle fractures. METHODS: All children with a lateral condyle fracture were prospectively enrolled at our institution between 2013 and 2016. Fractures were classified and treated on the basis of the following classification system: type 1: <2 mm; treated with long arm casting, type II: 2 to 4 mm; treated with closed reduction and percutaneous pinning (CRPP), and type III: >4 mm; open reduction and percutaneous pinning (ORPP). Functional outcomes were assessed at 6 to 12 weeks and at 1-year follow-ups using the Pediatric Outcomes Data Collection Instrument (PODCI). RESULTS: A total of 55 patients (mean age, 6 y; range 2 to 12 y) were prospectively enrolled. There were 17 (31%) type I fractures treated with a long arm cast, 8 (15%) type II treated with CRPP, and 30 (54%) type III treated with ORPP. Postoperative complications included delayed union (N=5) and pin site infection (N=3). Delayed unions on the basis of fracture type was type I (1/17, 6%), type II (1/8, 13%), and type III (3/30, 10%) (P=0.85). The rate of delayed unions in type II and III fractures fixed with k-wires was 11% (4/38). Four patients required a second operation with screw fixation. No significant differences were found across PODCI domains at 1-year follow-up when comparing our study population with normative data. CONCLUSIONS: This is the first prospective study of a treatment protocol for pediatric lateral condyle fractures and validates the use of displacement as a guide for best evidence-based treatment. Children with a lateral condyle fracture can achieve excellent functional outcomes in all classification types with comparable complication rates when radiographic fracture displacement is used to guide surgical and clinical decision making. LEVEL OF EVIDENCE: Level II.

BACKGROUND: Proximal junctional kyphosis (PJK) is a major complication after posterior spinal surgery. It is diagnosed radiographically based on a proximal junctional angle (PJA) and clinically when proximal extension is required. We hypothesized that abnormal spinopelvic alignment will increase the risk of PJK in children with early-onset scoliosis (EOS). METHODS: A retrospective study of 135 children with EOS from 2 registries, who were treated with distraction-based implants. Etiologies included 54 congenital, 10 neuromuscular, 37 syndromic, 32 idiopathic, and 2 unknown. A total of 89 rib-based and 46 spine-based surgeries were performed at a mean age of 5.3±2.83 years. On sagittal radiographs, spinopelvic parameters were measured preoperatively and at last follow-up: scoliosis angle (Cobb method, CA), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope and PJA. Radiographic PJK was defined as PJA≥10 degrees and PJA≥10 degrees greater than preoperative measurement. The requirement for the proximal extension of the upper instrumented vertebrae was considered a proximal junctional failure (PJF). Analysis of risk factors for the development of PJK and PJF was performed. RESULTS: At final follow-up (mean: 4.5±2.6 y), CA decreased (P<0.005), LL (P=0.029), and PI (P<0.005) increased, whereas PI-LL (pelvic incidence minus lumbar lordosis) did not change (P=0.706). Overall, 38% of children developed radiographic PJK and 18% developed PJF. Preoperative TK>50 degrees was a risk factor for the development of radiographic PJK (relative risk: 1.67, P=0.04). Children with high postoperative CA [hazard ratio (HR): 1.03, P=0.015], postoperative PT≥30 degrees (HR: 2.77, P=0.043), PI-LL>20 degrees (HR: 2.92, P=0.034), as well as greater preoperative to postoperative changes in PT (HR: 1.05, P=0.004), PI (HR: 1.06, P=0.0004) and PI-LL (HR: 1.03, P=0.013) were more likely to develop PJF. Children with rib-based constructs were less likely to develop radiographic PJK compared with children with spine-based distraction constructs (31% vs. 54%, respectively, P=0.038). CONCLUSIONS: In EOS patients undergoing growth-friendly surgery for EOS, preoperative TK>50 degrees was associated with increased risk for radiographic PJK. Postoperative PI-LL>20 degrees, PT≥30 degrees, and overcorrection of PT and PI-LL increased risk for PJF. Rib-based distraction construct decreased the risk for radiographic PJK in contrast with the spine-based constructs. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Recently, there have been several reports of using an enhanced discharge pathway following posterior spinal fusion (PSF) in patients with adolescent idiopathic scoliosis (AIS). No previous studies have prospectively examined patient satisfaction of patients with AIS using an enhanced discharge pathway. The purpose of this study was to evaluate patient satisfaction with an enhanced discharge pathway for PSF and whether patients felt that their length of stay was appropriate. METHODS: Patients with AIS undergoing PSF were prospectively enrolled. At their first postoperative clinic visit, patients were administered a survey regarding their experience. RESULTS: Of the 46 patients enrolled (mean age, 14 y), 1 was discharged on postoperative day (POD) 2, 33 were discharged on POD 3, 9 were discharged on POD 4, and 3 were discharged on POD 5. Eighty (37/46) of patients felt that they were discharged at an appropriate time, whereas 20% (9/46) felt they were discharged too early. Patients who felt they were discharged at an appropriate time (mean, 3.2 d) had a trend toward shorter stays than those who felt they were discharged too early (mean, 3.7 d). Overall patient satisfaction of hospital stay was high with a mean of 9 on a 10-point scale (range, 1 to 10). There was no correlation between length of stay and patient satisfaction (P=0.723). Patients who felt they were discharged early had a significantly higher mean FACES pain scores than those who felt they were discharged about right both as inpatients (mean, 4.8 vs. 3.4; P=0.0319) and at their first postoperative clinic visit (5.4 vs. 2.9; P=0.004). CONCLUSIONS: Eighty percent of patients with AIS who underwent PSF felt that the time of discharge was appropriate with an enhanced discharge pathway. There was no correlation between patient satisfaction and length of stay. LEVEL OF EVIDENCE: Level II.
