RESUMO
INTRODUCTION: Anterior vertebral body tethering (AVBT) is increasingly popular as an option for surgical treatment of idiopathic scoliosis (IS). While the technology remains new, it is important for families and patients to be able to compare it to the current standard of care, posterior spinal fusion (PSF). The purpose of this study is to describe the complication rate of AVBT in IS using the mCDS and to compare it to the recently reported complication rate of PSF in IS. METHODS: A multicenter pediatric spine deformity database was queried for all idiopathic scoliosis patients who underwent vertebral body tethering. There were 171 patients with a minimum 9-month follow-up included in this study. Complications were retrospectively graded by 2 attending pediatric spine surgeons using the mCDS classification system. RESULTS: Data from 171 patients with idiopathic scoliosis was available for analysis, with 156/171 (91%) of patients being female and an average age of 12.2 years old at surgery. There were 156 thoracic tethers (1 with an LIV below L2), 5 lumbar tethers, 9 staged double tethers, and only 1 patient with same-day double tether. Fifty-five (55) (32%) patients experienced a total of 69 complications. The most common complication type for VBT by mCDS was Grade IIIb, encompassing 29/69 (42%) of complications. The second most frequent complication grade was Grade I at 23/69 (33%). Thirty-four (34) out of 69 (49%) of the VBT complications reported required either procedural/surgical intervention or admission to the ICU. CONCLUSIONS: This is the first study to directly compare the complication profile of VBT to PSF using the mCDS. Forty-nine percent (49%) of the VBT complications reported were at least Grade III, while only 7% of complications in the control PSF cohort from the literature were Grade III or higher. The mCDS complication classification brings light to the early learning experience of a new technique compared to the widely accepted standard of PSF for IS. LEVEL OF EVIDENCE: III - Retrospective comparative study.

BACKGROUND: There is no uniform classification system for traumatic upper cervical spine injuries in children. This study assesses the reliability and reproducibility of the AO Upper Cervical Spine Classification System (UCCS), which was developed and validated in adults, to children. METHODS: Twenty-six patients under 18 years old with operative and nonoperative upper cervical injuries, defined as from the occipital condyle to the C2-C3 joint, were identified from 2000 to 2018. Inclusion criteria included the availability of computed tomography and magnetic resonance imaging at the time of injury. Patients with significant comorbidities were excluded. Each case was reviewed by a single senior surgeon to determine eligibility. Educational videos, schematics describing the UCCS, and imaging from 26 cases were sent to 9 pediatric orthopaedic surgeons. The surgeons classified each case into 3 categories: A, B, and C. Inter-rater reliability was assessed for the initial reading across all 9 raters by Fleiss's kappa coefficient (kF) along with 95% confidence intervals. One month later, the surgeons repeated the classification, and intra-rater reliability was calculated. All images were de-identified and randomized for each read independently. Intra-rater reproducibility across both reads was assessed using Fleiss's kappa. Interpretations for reliability estimates were based on Landis and Koch (1977): 0 to 0.2, slight; 0.2 to 0.4, fair; 0.4 to 0.6, moderate; 0.6 to 0.8, substantial; and >0.8, almost perfect agreement. RESULTS: Twenty-six cases were read by 9 raters twice. Sub-classification agreement was moderate to substantial with α κ estimates from 0.55 for the first read and 0.70 for the second read. Inter-rater agreement was moderate (kF 0.56 to 0.58) with respect to fracture location and fair (kF 0.24 to 0.3) with respect to primary classification (A, B, and C). Krippendorff's alpha for intra-rater reliability overall sub-classifications ranged from 0.41 to 0.88, with 0.75 overall raters. CONCLUSION: Traumatic upper cervical injuries are rare in the pediatric population. A uniform classification system can be vital to guide diagnosis and treatment. This study is the first to evaluate the use of the UCCS in the pediatric population. While moderate to substantial agreement was found, limitations to applying the UCCS to the pediatric population exist, and thus the UCCS can be considered a starting point for developing a pediatric classification. LEVEL OF EVIDENCE: Level III.

Meetings have become a near-constant presence in the practicing pediatric orthopaedist's day. While many meetings are productive and efficient, others may represent a time vortex that take precious hours away from other meaningful pursuits. Organizers and participants in meetings have an obligation to optimize these gatherings whenever possible. Selecting optimal times, ensuring that the minutes together are spent efficiently, creating an agenda and presenting ideas to be discussed in an effective manner, actively listening to other participants, and debriefing are all ways that meetings can be made more productive and enjoyable.

BACKGROUND: Indications for posterior spinal fusion (PSF) with segmental spinal instrumentation (SSI) of a scoliotic deformity in a skeletally mature individual are based on the balance between the anticipated benefit of stopping future curve progression and the potential downside of loss of spinal mobility. The dilemma regarding PSF with SSI in the adolescent population is exacerbated by the patient's participation in athletics requiring flexibility and motion of the spine, the location of the curve, the presence of pelvic obliquity, and the impact of a limb length discrepancy. The purpose of this review is to discuss the potential advantages and disadvantages of PSF with SSI in a hypothetical skeletally mature adolescent with a 45-degree lumbar curve, pelvic obliquity, and limb length discrepancy. DISCUSSION: Natural history studies of untreated adolescent idiopathic scoliosis (AIS) have shown that slow curve progression throughout adulthood is likely. Adults with untreated AIS may also have more back pain and dissatisfaction with their appearance. Although the clinical and radiographic outcomes of PSF with SSI are excellent, patients should be counseled about the impact of fusing the lumbar spine on back pain, decreased spinal mobility, and potential inability to return to athletics at the same level. Adults who undergo surgery for AIS have greater operative morbidity and number of levels fused compared with adolescents. CONCLUSION: These factors should be presented when discussing observation versus PSF with SSI with patients and families. Delaying surgery until formal athletic participation is complete should be considered.

BACKGROUND: Although halo gravity traction (HGT) has been used to treat children with severe spinal deformity for decades, there is a distinct lack of high-quality evidence to speak to its merits or to dictate ideal manner of implementation. In addition, no guidelines exist to drive research or assist surgeons in their practice. The aim of this study was to establish best practice guidelines (BPG) using formal techniques of consensus building among a group of experienced pediatric spinal deformity surgeons to determine ideal indications and implementation of HGT for pediatric spinal deformity. METHODS: The Delphi process and nominal group technique were used to formally derive consensus among leaders in pediatric spine surgery. Initial work identified significant areas of variability in practice for which we sought to garner consensus. After review of the literature, 3 iterative surveys were administered from February through April 2018 to nationwide experts in pediatric spinal deformity. Surveys assessed anonymous opinions on ideal practices for indications, preoperative evaluation, protocols, and complications, with agreement of 80% or higher considered consensus. Final determination of consensus items and equipoise were established using the Nominal group technique in a facilitated meeting. RESULTS: Of the 42 surgeons invited, responses were received from 32, 40, and 31 surgeons for each survey, respectively. The final meeting included 14 experts with an average 10.5 years in practice and average 88 annual spinal deformity cases. Experts reached consensus on 67 items [indications (17), goals (1), preoperative evaluations (5), protocols (36), complications (8)]; these were consolidated to create final BPG in all categories, including statements to help dictate practice such as using at least 6 to 8 pins under 4 to 8 lbs of torque, with a small, tolerable starting weight and reaching goal weight of 50% TBW in â¼2 weeks. Nine items remained items of equipoise for the purposes of guiding future research. CONCLUSIONS: We developed consensus-based BPG for the use and implementation of HGT for pediatric spinal deformity. This can serve as a measure to help drive future research as well as give new surgeons a place to begin their practice of HGT. LEVEL OF EVIDENCE: Level V-expert opinion.

BACKGROUND: The purpose of this study was to determine whether the new AOSpine thoracolumbar spine injury classification system is reliable and reproducible when applied to the pediatric population. METHODS: Nine POSNA (Pediatric Orthopaedic Society of North America) member surgeons were sent educational videos and schematic papers describing the AOSpine thoracolumbar spine injury classification system. The material also contained magnetic resonance imaging and computed tomography imaging of 25 pediatric patients with thoracolumbar spine injuries organized into cases to review and classify. The evaluators classified injuries into 3 primary categories: A, B, and C. Interobserver reliability was assessed for the initial reading by Fleiss kappa coefficient (kF) along with 95% confidence interval (CI). For A and B type injuries, subclassification was conducted including A0 to A4 and B1 to B2 subtypes. Interobserver reliability across subclasses was assessed using Krippendorff alpha (αk) along with bootstrapped 95% CI. Imaging was reviewed a second time by all evaluators ~1 month later. All imaging was blinded and randomized. Intraobserver reproducibility was assessed for the primary classifications using Fleiss kappa and subclassification reproducibility was assessed by Krippendorff alpha (αk) along with 95% CI. Interpretations for reliability estimates were based on Landis and Koch (1977): 0 to 0.2, slight; 0.2 to 0.4, fair; 0.4 to 0.6, moderate; 0.6 to 0.8, substantial; and >0.8, almost perfect agreement. RESULTS: Twenty-five cases were read for a total of 225 initial and 225 repeated evaluations. Adjusted interobserver reliability was almost perfect (kF=0.82; CI, 0.77-0.87) across all raters. Subclassification reliability was substantial (αK=0.79; CI, 0.62-0.90). Adjusted intraobserver reproducibility was almost perfect (kF=0.81; CI, 0.71-0.90) for both primary classifications and for subclassifications (αk=0.81; CI, 0.73-0.86). CONCLUSIONS: The reliability for the AOSpine thoracolumbar spine injury slassification System was high amongst POSNA surgeons when applied to pediatric patients. Given a lack of a uniform classification in the pediatric population, the AOSpine thoracolumbar spine injury classification system has the potential to be used as the first universal spine fracture classification in children. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Flexion-type supracondylar humerus fractures are much more uncommon than their extension-type counterparts. Instability in elbow flexion renders traditional closed techniques inadequate and often results in the need for open reduction. We present a simple technique for closed reduction using a transolecranon pin for temporary stability. METHODS: A retrospective review of 9 patients treated with a transolecranon pin technique for a flexion-type supracondylar humerus fracture was performed. Operative time, need for open reduction, postoperative range of motion, final radiographic alignment using Baumann angle, and the intersection of the anterior humeral line with the capitellum was evaluated. RESULTS: All 9 patients were treated with closed reduction using a temporary transolecranon pin technique. Total surgical time averaged 38±15 minutes and was longer for type III than type II flexion-type fractures. All fractures healed by first follow-up at 1 month. There was 1 preoperative ulnar nerve deficit that resolved by the first postoperative visit. Average Baumann angle at radiographic healing was 71.2±3.3 degrees and all cases showed restoration of the normal anterior humeral line:capitellar relationship. Average postoperative flexion at final follow-up was 125 degrees and extension was 5 degrees. One patient had a flexion contracture of 10 degrees. DISCUSSION: Use of a temporary transolecranon pin allowed for closed reduction of all flexion-type fractures with no radiographic malunion. This technique is technically simple and avoids the need for open reduction or multiple fluoroscopy views. LEVEL OF EVIDENCE: Level IV-case series.

BACKGROUND: Assessment of changes in anatomic alignment following guided growth traditionally utilizes full-length standing radiographs which subjects patients to larger radiation doses than does a single anteroposterior radiograph of the knee. In an effort to minimize radiation exposure, the present study sought to determine whether changes in screw divergence (SD) of the 2-hole tension band plate used for hemiepiphysiodesis reliably predicts change in alignment. METHODS: A retrospective review was conducted involving all patients with genu varum or genu valgum treated with hemiepiphysiodesis at a single institution. Preoperative anatomic alignment of the femur, using anatomic lateral distal femoral angle (aLDFA) and anatomic femoral-tibial angle (aTFA), and intraoperative divergence of hemiepiphysiodesis screws were compared with postoperative imaging. Linear regression analysis determined the relationship between changes in SD and changes in alignment, and multivariate regression analysis explored the relationship between the angular changes being measured and various demographic factors. RESULTS: Linear regression analysis revealed that for every 1 degree change in SD there was a resultant 1.80 degrees of change in aTFA and 2.11 degrees of change in aLDFA. Change in aTFA is predicted by the equation: [INCREMENT]aTFA=0.41×|[INCREMENT]SD|+1.39. The change in aLDFA was predicted by the equation [INCREMENT]aLDFA=0.27×[INCREMENT]SD+1.84 with a R2 of 0.31. [INCREMENT]aTFA and [INCREMENT]SD had a correlation coefficient of 0.68 (95% confidence interval, 0.54-0.78.) [INCREMENT]aLDFA and [INCREMENT]SD had a correlation coefficient of 0.56 (95% confidence interval, 0.42-0.68). [INCREMENT]SD and sex were the only 2 independent predictors for [INCREMENT]aLDFA and [INCREMENT]aTFA as determined by multivariate regression analysis. CONCLUSION: Change in coronal plane anatomic alignment in patients being treated for genu valgum or genu varum with hemiepiphysiodesis can be reasonably estimated by measuring the change in SD. Therefore, when following patients postoperatively, focal radiographic imaging of the knee can be utilized in lieu of standing full-length limb radiographs to limit radiation to the pelvis in this sensitive patient population. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

INTRODUCTION: Hospital stay after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) has decreased only modestly over time despite a healthy patient population. The purpose of this study was to evaluate the impact of a novel postoperative pathway on length of stay (LOS) and complications. METHODS: A retrospective review of patients undergoing PSF for AIS in 2011 to 2012 was performed at 2 institutions evaluating demographics, preoperative Cobb angles, surgical duration, blood loss, LOS, and postoperative complications. Patients at one center were managed using an accelerated discharge (AD) pathway emphasizing early transition to oral pain medications mobilization with physical therapy 2 to 3 times/d, and discharge regardless of return of bowel function. Expectations were set with the family before surgery for early discharge. Patients at the other center were managed without a standardized pathway. RESULTS: One hundred five patients underwent PSF and were treated by an AD pathway, whereas 45 patients were managed using a traditional discharge (TD) pathway. There was no difference in proximal thoracic and main thoracic Cobb magnitudes and a small difference in thoracolumbar curve magnitudes (35.2±13.0 degrees AD vs. 40.6±11.4 degrees TD, P=0.004) between groups. Surgical time was slightly shorter in AD patients (median 3.1 vs. 3.9 h, P=0.0003) with no difference in estimated blood loss. LOS was 48% shorter in the AD group (2.2 vs. 4.2 d, P<0.0001). There was no difference in readmissions or wound complications between groups. CONCLUSIONS: Hospital stay was nearly 50% shorter in patients managed by the AD pathway without any increase in readmissions or early complications. SIGNIFICANCE: Discharge after PSF for AIS may be expedited using a coordinated postoperative pathway. No increase in complications was seen using the AD pathway. Earlier discharge may reduce health care costs and allow an earlier return to normalcy for families. LEVEL OF EVIDENCE: Level III-case control study.

OBJECTIVE: To evaluate whether the time from symptom onset to diagnosis of slipped capital femoral epiphysis (SCFE) has improved over a recent decade compared with reports of previous decades. STUDY DESIGN: Retrospective review of 481 patients admitted with a diagnosis of SCFE at three large pediatric hospitals between January 2003 and December 2012. RESULTS: The average time from symptom onset to diagnosis of SCFE was 17 weeks (range, 0-to 169). There were no significant differences in time from symptom onset to diagnosis across 2-year intervals of the 10-year study period (P = .94). The time from evaluation by first provider to diagnosis was significantly shorter for patients evaluated at an orthopedic clinic (mean, 0 weeks; range, 0-0 weeks) compared with patients evaluated by a primary care provider (mean, 4 weeks; range, 0-52 weeks; r = 0.24; P = .003) or at an emergency department (mean, 6 weeks, range, 0-104 weeks; r = 0.36; P = .008). Fifty-two patients (10.8%) developed a second SCFE after treatment of the first affected side. The time from the onset of symptoms to diagnosis for the second episode of SCFE was significantly shorter (r = 0.19; P < .001), with mean interval of 11 weeks (range, 0-104 weeks) from symptom onset to diagnosis. There were significantly more cases of mildly severe SCFE, as defined by the Wilson classification scheme, in second episodes of SCFE compared with first episodes of SCFE (OR, 4.44; P = .001). CONCLUSION: Despite reports documenting a lag in time to the diagnosis of SCFE more than a decade ago, there has been no improvement in the speed of diagnosis. Decreases in both the time to diagnosis and the severity of findings for the second episode of SCFE suggest that the education of at-risk children and their families (or providers) may be of benefit in decreasing this delay.

PURPOSE: To evaluate the technical feasibility and clinical efficacy of osteoid osteoma (OO) cryoablation in a large, pediatric/adolescent cohort. MATERIALS AND METHODS: An electronic medical record and imaging archive review was performed to identify all cryoablations performed for OOs between 2011 and 2015 at a single tertiary care pediatric hospital. The subsequent analysis included 29 patients with suspected OOs treated by cryoablation (age range, 3-18 y; mean age, 11.3 y; 17 boys; 12 girls). Conventional CT guidance was used in 22 procedures; cone-beam CT guidance was used in 7 procedures. Follow-up data were obtained via a standardized telephone questionnaire (23/29 patients; 79.3%) and clinical notes (5/29 patients; 17.2%). One patient was lost to follow-up. RESULTS: Technical success was achieved in 100% of patients (29/29). Immediate clinical success (cessation of pain and nonsteroidal antiinflammatory drug [NSAID] use within 1 mo after the procedure) was achieved in 27/28 patients (96.4%). Short-term clinical success (cessation of pain and NSAID use for > 3 mo after the procedure) was achieved in 24/25 patients (96%). Long-term clinical success (cessation of pain and NSAID use for > 12 mo after the procedure) was achieved in 19/21 patients (90.5%). Median pain scale score before the procedure was 10 (range, 5-10); median pain scale score after the procedure was 0 (range, 0-8; P < .0001). There were 6 minor complications (21%) and no major complications. CONCLUSION: Image-guided cryoablation is a technically feasible, clinically efficacious therapeutic option for children and adolescents with symptomatic OO.

INTRODUCTION: A dramatic increase in the number of pediatric orthopaedic fellows being trained has led to concerns that there may be an oversupply of pediatric orthopaedists. The purpose of this study was to determine whether this perception is accurate and whether the practice expectations of recent pediatric fellowship graduates are being met by surveying recent pediatric fellowship graduates about their early practice experiences. METHODS: A 36-question survey approved by the Pediatric Orthopaedic Society of North America (POSNA) leadership was electronically distributed to 120 recent graduates of pediatric orthopaedic fellowships; 81 responses were ultimately obtained (67.5% response rate). RESULTS: Almost all (91%) of the respondents were very or extremely satisfied with their fellowship experience. Half of the respondents had at least 1 job offer before they entered their fellowships. After completion of fellowships, 35% received 1 job offer and 62.5% received ≥2 job offers; only 2.5% did not receive a job offer. Most reported a practice consisting almost entirely of pediatric orthopaedics, and 93.5% thought this was in line with their expectations; 87% indicated satisfaction with their current volume of pediatric orthopaedics, and 85% with the complexity of their pediatric orthopaedic cases. Despite the high employment percentages and satisfaction with practice profiles, nearly a third (28%) of respondents replied that too many pediatric orthopaedists are being trained. CONCLUSIONS: Positive messages from this survey include the satisfaction of graduates with their fellowship training, the high percentage of graduates who readily found employment, and the satisfaction of graduates with their current practice environments; this indicates that the pediatric orthopaedic job environment is not completely saturated and there are continued opportunities for graduating pediatric fellows despite the increased number of fellows being trained. Although not determined by this study, it may be that the stable demand for pediatric orthopaedic services is being driven by the expansion of the scope of practice as well as subspecialization within the practice of pediatric orthopaedics.

BACKGROUND: The transition into practice following a fellowship in pediatric orthopaedics is challenging. This study seeks to describe the first-year experiences of 5 pediatric orthopaedists. METHODS: An Institutional Review Board-approved retrospective review was conducted of 5 pediatric orthopaedic surgeons' first year in practice. All were fellowship trained and practiced at private or academic subspecialty groups. Clinical volume, payor mix, surgical cases, as well as complications were evaluated. RESULTS: A total of 1172 surgical procedures were available for review. Surgeons performed an average of 234 cases with a mean case load of 19.5 procedures per month. Fracture care and surgical management of infection represented the largest number of procedures. 42.3% of patients were covered by government insurance or were uninsured. Surgeons saw an average of 30.5 new patients per week in clinic. Of these, 10.7% of patients were scheduled for an elective surgical case. A sample of clinical practice revealed that 41.3% of patients were covered by government or no insurance. 17.8% of surgical patients sustained a complication with the majority being minor or expected. 18.8% of complications were major and required repeat operation. Complications peaked in the fourth month of practice. CONCLUSIONS: Although clinical and surgical volumes can vary during the first year of practice, fracture care and surgical management of infection represent the majority of operative cases. A large portion of surgical volume results from emergent care, whereas elective cases are more elusive with only 1 in 10 elective patients resulting in surgical treatment. Despite a significant number of untoward events related to surgery, major surgical complications are uncommon in the first year of practice. CLINICAL RELEVANCE: The majority of surgical cases in the first year of practice are due to trauma and infection. A high volume of patients must be seen to establish a practice, particularly given the high rate of Medicaid patients. These figures provide benchmarks to guide training programs and to establish realistic expectations for new pediatric orthopaedic surgeons and their partners.

BACKGROUND: The safety of delayed surgical treatment of severe supracondylar elbow fractures in children remains debated. No large studies have evaluated complications of injury and surgery evaluating only type 3 fractures. Our aim was to review the results of our experience treating children with severe supracondylar elbow fractures at various time points after injury. METHODS: All children treated operatively for supracondylar humerus fractures from 2004 to 2007 at a single pediatric trauma center were identified. A total of 1296 children had operative treatment, of which 872 had type 3 fractures. Clinical records were reviewed to identify time to surgery from presentation at our institution. Patients were grouped into 4 cohorts [<6 h (n=325), 6 to 12 h (n=224), 12 to 24 h (n=295), and >24 h (n=28)]. Emergency, operative, inpatient, and outpatient records were reviewed to determine morbidity at presentation as well as operative and postoperative complications. RESULTS: There was no difference in sex, age, or energy mechanism between children in the various time groups. An absent pulse was found in 54 children (6%) at presentation, of which only 5 ultimately required a vascular intervention. Nerve injury occurred in 105 patients (12%). Use of a medial entry pin was not associated with ulnar nerve injury. Increased time from presentation to surgery was not associated with increased morbidity from the injury or treatment complications. In contrast, there was a trend to steady decrease in morbidity and complication rates with increased time to surgery. CONCLUSIONS: This is the largest single-center study of severe supracondylar humerus fractures and describes rates of vascular compromise, nerve injury, infection, and other complications of these injuries. Most children with type 3 supracondylar humerus fractures can be treated safely in a delayed manner. Appropriate clinical judgment is imperative to optimize outcomes. LEVEL OF EVIDENCE: Level III--retrospective comparative study.

BACKGROUND: Because of the changing referral patterns, operative pediatric supracondylar humerus fractures are increasingly being treated at tertiary referral centers. To expedite patient flow, type II fractures are sometimes pinned in a delayed manner. We sought to determine if delay in surgical treatment of modified Gartland type II supracondylar humerus fractures would affect the rate of complications following closed reduction and percutaneous pinning. METHODS: We performed a retrospective review of a consecutive series of 399 modified Gartland type II supracondylar fractures treated operatively at a tertiary referral center over 4 years. Mean patient age in the type II group was 5 years (range, 1 to 15 y). A total of 48% were pinned within 24 hours, 52% pinned >24 hours after the injury. RESULTS: No difference was in detected in rates of major complications between the early and delayed treatment group. Four percent of patients sustained a complication (16 patients). There were no compartment syndromes, vascular injuries, or permanent nerve injuries. Complications included nerve injury (3), physical therapy referral for stiffness (3), pin site infection (2 treated with oral antibiotics, 4 treated with debridement), refracture (2), and loss of fixation or broken hardware (2). Of the 3 patients who sustained nerve injuries, all underwent surgery within 24 hours of injury. One patient developed an ulnar motor and sensory nerve palsy after fixation with crossed K-wires. This resolved by 7 weeks postoperatively. Two patients presented with an anterior interosseous nerve palsy-1 resolved 1 week after surgery, the other by 8 weeks postoperatively. CONCLUSIONS: Delay in surgery did not result in an increased rate of major complications following closed reduction and percutaneous pinning of type II supracondylar humerus fractures in children. Further prospective work is necessary to determine if there are subtle treatment benefits from emergent treatment of type II supracondylar humerus fractures. LEVEL OF EVIDENCE: Level III-retrospective comparative series.

STUDY DESIGN: Prospective Cohort Study. OBJECTIVE: The present study aims to determine if the racial representation of patients enrolled in a large prospective scoliosis registry is reflective of the general United States population. Further, we studied whether there was an association between race, pre-operative parameters, outcomes and loss to follow-up. METHODS: Prospectively collected data for patients who underwent spinal fusion for adolescent idiopathic scoliosis (AIS) was reviewed, including self-reported race/ethnicity. The U.S. pediatric population and U.S. patients enrolled in the prospective registry were compared. The data obtained was analyzed for variations between races, for pre-operative variables and follow-up. RESULTS: Of the 2210 included patients in the registry 66% of patients reported as White, while 52% of the 2018 U.S. pediatric population reported as White. 15% of the registry reported as Hispanic/Latino compared to 22% of the U.S. pediatric population, 13% Black compared to 14% of the U.S. pediatric population, and 4% Asian compared to 5% of the U.S. pediatric population. Asian and White patients had statistically significant higher 2-year follow-up in all but one of six enrollment sites (P < 0.001). Native American, Other, and Hispanic/Latino patients had the highest BMIs. Native American and Black patients had the highest pre-op thoracic Cobb angles. Pre-op ages of Black, Hispanic, and Native American patients were statistically lower (P < 0.01). CONCLUSION: This study demonstrates the association between race and patient follow-up and pre-operative factors in patients who underwent surgery for AIS. Black, Native American, and Hispanic populations were underrepresented both at pre-op and follow-up when compared to their relative proportion in the U.S. pediatric population.
RESUMO
PURPOSE: Vertebral body tethering (VBT) is a non-fusion alternative to posterior spinal fusion (PSF). There have been few reports on VBT of two curvatures. We aim to compare the radiographic outcomes between VBT and PSF in patients with double curvatures in which both curves were instrumented. METHODS: 29 AIS patients matched by Lenke, age (± 2 years), triradiate cartilage closure status, major Cobb angle (± 8°), and T5-T12 kyphosis (± 10°). Variables were compared using Wilcoxon rank-sum tests, Student's t tests, and chi-Square. Clinical success was defined as major curve < 35°. RESULTS: Group baseline demographics were similar. Major thoracic (T) curve types had significantly better major (VBT 51.5 ± 7.9° to 31.6 ± 12.0° [40%] vs. PSF 54.3 ± 7.4° to 17.4 ± 6.5° [68%]; p = 0.0002) and secondary curve correction in the PSF group. 71% of major T VBT patients were clinically successful versus 100% of PSF. Major thoracolumbar (TL) curve types experienced comparable major (VBT 52.3 ± 7.0° to 18.3 ± 11.4° (65%) vs. PSF 53.0 ± 5.2° to 23.8 ± 10.9° (56%); p = 0.2397) and secondary curve correction. 92% of major TL VBT patients were clinically successful versus 75% in the PSF group. There was no difference in T5-12 kyphosis or lumbar lordosis between groups for any curve type. There were 4 patients (13.8%) with major complications in the VBT group compared to 0 (0%) in the PSF. CONCLUSION: Patients with double major AIS who underwent VBT with major T curve types had less correction than PSF; however, those with major TL curves experienced similar radiographic outcomes regardless of procedure. Complications were greater for VBT.

BACKGROUND: Severe adolescent idiopathic scoliosis (AIS) can be treated with instrumented fusion, but the number of anchors needed for optimal correction is controversial. METHODS: We conducted a multicenter, randomized study that included patients undergoing spinal fusion for single thoracic curves between 45° and 65°, the most common form of operatively treated AIS. Of the 211 patients randomized, 108 were assigned to a high-density screw pattern and 103, to a low-density screw pattern. Surgeons were instructed to use ≥1.8 implants per spinal level fused for patients in the high-implant-density group or ≤1.4 implants per spinal level fused for patients in the low-implant-density group. The primary outcome measure was the percent correction of the coronal curve at the 2-year follow-up. The power analysis for this trial required 174 patients to show equivalence, defined as a 95% confidence interval (CI) within a ±10% correction margin with a probability of 90%. RESULTS: In the intention-to-treat analysis, the mean percent correction of the coronal curve was equivalent between the high-density and low-density groups at the 2-year follow-up (67.6% versus 65.7%; difference, -1.9% [95% CI: -6.1%, 2.2%]). In the per-protocol cohorts, the mean percent correction of the coronal curve was also equivalent between the 2 groups at the 2-year follow-up (65.0% versus 66.1%; difference, 1.1% [95% CI: -3.0%, 5.2%]). A total of 6 patients in the low-density group and 5 patients in the high-density group required reoperation (p = 1.0). CONCLUSIONS: In the setting of spinal fusion for primary thoracic AIS curves between 45° and 65°, the percent coronal curve correction obtained with use of a low-implant-density construct and that obtained with use of a high-implant-density construct were equivalent.

PURPOSE: The treatment of distal radius fractures with volar locked plating (VLP) has gained popularity. Many different designs and sizes of plates afford a wide variety of configurations of locking screws that can be placed into the distal fracture fragment. The purpose of this study was to determine whether using half of the distal locking screws decreased stability when compared with using all possible distal locking screws with 4 different VLP systems. METHODS: Twenty-four identical synthetic distal radius sawbone models were instrumented with 1 of 4 designs of VLP devices over a standardized dorsal wedge osteotomy to simulate a dorsally comminuted, extra-articular distal radius fracture. Distal locking screws were placed in varying configurations. Six radii per plate model with different screw configurations then underwent axial loading, volar bending, and dorsal bending using a servohydraulic machine. Distal fragment displacement was recorded using a differential variable reluctance transducer. RESULTS: There was no significant difference in fracture fragment displacement when using half of the distal locking screw set compared with using the full screw set. Mean differences in displacement between half and full screws were less than 0.1 mm. All configurations had the greatest magnitude of displacement during axial loading. Mean displacement was less in plates containing 2 rows of distal locking screws (-0.4 mm) compared with plates containing 1 row (-0.6 mm). CONCLUSIONS: Using half of the distal locking screws in VLP in an extra-articular, nonosteoporotic distal radial fracture model with noncyclical, nondestructive loading does not decrease construct stability compared with using all of the screws. Not filling all holes in VLP is more cost effective and does not sacrifice plate stiffness or construct stability. Plates with 2 rows of distal locking screws create more stable fixation than plates with 1 row of distal locking screws.

INTRODUCTION: Posterior spinal fusion (PSF) represents a large physiologic challenge for children with neuromuscular scoliosis (NMS). Perioperative complications are numerous with many occurring in the post-operative period due to pain and relative immobilization. This study assessed the impact of steroids on patients undergoing PSF for NMS. METHODS: A retrospective review of consecutive patients managed at a single center with PSF for NMS was reviewed. Clinical and radiographic analysis was used to evaluate baseline demographics, curve characteristics, and post-operative course. RESULTS: Eighty-nine patients who underwent PSF for NMS were included. Fifty-seven of these patients did not receive post-operative steroids (NS) while 32 patients were treated with post-operative steroids (dexamethasone, WS) for a median of 3 doses (median 6.0 mg/dose every 8 h after surgery). The demographic variables of the cohorts were similar with no difference in curve magnitude, number of vertebrae fused, number of osteotomies, or EBL between groups. A 70% decrease in the median post-operative morphine equivalents was observed in the steroid cohort (0.50 mg/kg WS vs 1.65 mg/kg NS, p value < 0.001). There was an association between post-operative morphine equivalents and length of stay (Spearman's rho = 0.22, p value = 0.04). There was no difference in wound healing, infection, and pulmonary or gastrointestinal complications between groups. No difference was found in pain at discharge, 30-day ED returns, or 30-day OR returns between groups. CONCLUSIONS: Post-operative dexamethasone resulted in a 70% decrease in morphine equivalent use after PSF for NMS without any increase in perioperative wound infections. LEVEL OF EVIDENCE: Level 3: case-control series.
