Background: Neuromuscular early-onset scoliosis (N-EOS) often presents with a long sweeping thoracolumbar scoliosis and pelvic obliquity. With severe pelvic obliquity, the ribs come into contact with the high side of the pelvis, termed rib-on-pelvis deformity (ROP). The goal of this study is to evaluate whether ROP is associated with reported pain and other health-related quality of life (HRQOL) measures. We hypothesize that ROP is associated with increased pain and negative HRQOL., Methods: A multicenter international registry was queried for all nonambulatory patients with N-EOS from 2012 to 2022. Both surgical and nonsurgical patients were included. ROP was classified as a binary radiographic assessment of preoperative (surgical patients) and most recent follow-up (nonsurgical patients) upright radiographs. Reported pain and other HRQOL measures were assessed through the 24-Item Early Onset Scoliosis Questionnaire (EOSQ-24). Patients with nonupright radiographs or EOSQ-24 questionnaires and corresponding radiographs >4 months apart were excluded., Results: Totally, 225 patients (8.4±3.1 y, 55% female) were included. The median major curve was 63.3 (IQR: 40.6 to 81.2) degrees and median pelvic obliquity was 15.5 degrees (IQR: 8.8 to 26.4). Eighty-three patients (37%) had ROP. ROP was associated with both frequency ( P <0.001) and severity ( P <0.001) of pain. ROP was associated with worse general health ( P =0.01), increased difficulty with vocalization ( P =0.02), increased frequency of shortness of breath ( P =0.002), and increased difficulty sitting upright ( P =0.04). Regarding overall EOSQ-24 domains, ROP was associated with worse general health, pain/discomfort, pulmonary function, and physical function ( P <0.01). In a subanalysis of 76 patients who underwent surgical intervention with at least 2 years of follow-up, patients with preoperative ROP experienced significantly greater improvements in both frequency ( P =0.004) and severity ( P =0.001) of pain than the patients without preoperative ROP at 2 years postoperatively., Conclusions: The overall incidence of ROP in N-EOS is about 37%. ROP is associated with greater pain and worse HRQOL through the EOSQ-24 questionnaire. Furthermore, these patients experienced a greater reduction in pain after surgery. Clinicians and parents must be aware that ROP is possibly a pain generator, but responds positively to surgical intervention., Level of Evidence: Level III., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Osteogenesis imperfecta (OI) is a genetic defect in collagen type I, phenotypically characterized by bony fragility and a propensity to high rates of childhood fracture. Fragility fractures in patients with OI have been reported with routine hospital care. In addition, there is a nonzero rate of iatrogenic fracture during orthopaedic surgery directly related to the technical steps of the procedure itself. The rate of this latter has never been explicitly investigated., Methods: A review of all patients at a single OI referral center was conducted, including all patients with a diagnosis of OI seen between 2013 and 2023, inclusive. All patients who underwent orthopaedic surgery of any kind were reviewed, and clinical and radiographic details of all procedures were extracted. Among the details examined were the OI subtype, surgery details, any implants used, intraoperative and hospital stay complications, modified Clavien-Dindo classification of complications, and ultimate outcome., Results: Eleven of 60 patients experienced an unplanned, iatrogenic intraoperative fracture during orthopaedic surgery (11/60 = 18.3%). This comprised 15 fractures among 356 total orthopaedic surgical episodes (15/356 = 4.2%). All but one fracture occurred on the operative long bone segment, all were a direct result of surgical steps, and 11 of 15 fractures occurred in the femur. Most fractures were secondary to the removal, insertion, or exchange of intramedullary implants in the lower extremity (11 of 15 fractures), most often the femur. Thirteen of 15 injuries were classified as modified Clavien-Dindo II or III, requiring modification of postop rehabilitation, additional treatments, or surgical intervention (87%). Overall, iatrogenic fracture was the most common intraoperative complication experienced in the cohort., Conclusions: Iatrogenic fracture during orthopaedic surgery for patients with OI is not uncommon. A sizeable minority of patients with OI undergoing orthopaedic surgery will experience unplanned fractures, most commonly in the femur, and care is altered in most instances. The risk of intraoperative fracture can be discussed with families of children with OI as part of informed consent and shared decision-making., Level of Evidence: Level IV-retrospective cohort series., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Introduction: Pediatric pelvic and acetabular fractures are rare but potentially devastating injuries and significant management variation exists across the United States. This study sought to elucidate treatment decision-making trends, involvement of adult trauma fellowship-trained surgeons in pediatric care, and pre- and postoperative transfer patterns., Methods: Pediatric orthopaedic surgeons who serve as trauma liaisons at 20 PTCs were surveyed regarding training, practice volume, and factors contributing to institutional management of pelvic and acetabular injuries. Five clinical scenarios of pelvic ring and acetabular fractures that varied by injury pattern, age, and sex were presented. Descriptive statistics were used to summarize the results., Results: Eighteen institutions responded to the survey (90% response rate, 16 Level, 1 PTC). All surgeons were pediatric fellowship-trained (77.7% in practice >5 y). The four most common factors affecting whether surgeons independently managed both pelvic ring and acetabular fractures were patient age, fracture characteristics, displacement and need for surgery. The majority reported managing <10 acetabular (72.2%) but >10 pelvic ring (77.8%) injuries per year. In the clinical scenarios, patients <10 were more likely to have treatment decisions made by a pediatric orthopaedic surgeon. Older patients were more likely to be transferred to another institution for surgery but were often transferred back to the PTC postoperatively. In all clinical scenarios other than posterior hip dislocation, a trauma fellowship-trained surgeon was more likely to be the operative surgeon, even when the patient was not transferred., Conclusions: There is substantial variation in the management of pediatric and adolescent pelvic and acetabular fractures. Even at tertiary care PTCs, volumes are low, and trauma fellowship-trained surgeons are often involved in decision-making and operative management. Age and injury pattern seem to play a large role in variation, and patient transfers between facilities are common., Level of Evidence: V., Competing Interests: J.S. is a consultant for OrthoPediatrics.

Objective: Adolescents with idiopathic scoliosis (IS) are often prescribed an orthosis to prevent curve progression and avoid surgery. Standard-of-care scoliosis orthoses are designed for full-time (FT) wear, which can be burdensome for some patients. Nighttime (NT) hypercorrective scoliosis orthoses are another option that has a lower impact on daily life, however, additional research is needed to guide the prescription of NT orthoses. The aim of this study was to assess the willingness of patients with IS and their parents/guardians to enroll in a randomized controlled study on bracing in scoliosis., Methods: A cross-sectional study was conducted to survey adolescents with IS and their parents/guardians. Eligibility criteria for adolescent participants included: (1) diagnosis of IS, (2) no previous orthosis use, (3) currently seeing a provider for their scoliosis, and (4) able to communicate in English. Parent/guardian participants were the parent or guardian of an adolescent participant and were able to communicate in English. Separate online surveys were designed for adolescents and their parents/guardians. Surveys provided information about a hypothetical study and queried respondents about whether they would participate in the study, their willingness to randomize brace treatment, and their preferences for NT or FT bracing. Descriptive statistics were used to summarize survey data., Results: One hundred four adolescent/parent dyads completed the survey (104 adolescents and 103 parents). Most participants (adolescents: 55.8%, parents: 55.3%) indicated an interest in study participation, and approximately one-third of participants (adolescents: 31.8%, parents: 30.1%) reported that they would be willing to randomize to brace type. Most participants (adolescent: 77.0%, parent: 81.6%) preferred the NT brace if they needed brace treatment., Conclusions: High-quality evidence is needed to inform the use of FT and NT scoliosis orthoses. Approximately a third of respondents would enroll in a randomized trial, indicating that multiple collaborative sites will be needed to recruit a sufficient sample into a randomized study on scoliosis bracing. Study findings also demonstrate support from adolescents and their parents/guardians for research on scoliosis bracing., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Purpose: To describe the incidence of reoperation and factors contributing to surgical revision within a minimum of 10 years after spinal fusion for scoliosis in patients with nonambulatory cerebral palsy (CP)., Methods: We conducted a retrospective review of consecutive nonambulatory patients with CP who underwent primary spinal fusion at a single specialty care center with a minimum of 10 years from their index surgery (surgery dates 2001-2011). Causes of reoperation were classified as implant failure/pseudoarthrosis, surgical site infection (SSI), proximal junctional kyphosis, prominent/symptomatic implants, and implant removal. Reoperation rates with 95% confidence intervals were calculated for each time interval, and an actuarial survival curve was generated., Results: 144 patients met inclusion criteria (mean age = 14.3 ± 2.6 years, 62.5% male); 85.4% had 5 years follow-up data; and 66.0% had 10 years follow-up data. Estimates from the actuarial analysis suggest that 14.9% (95% CI: 10.0-22.0) underwent reoperation by 5 years postsurgery, and 21.7% (95% CI: 15.4-30.1) underwent reoperation by 10 years postsurgery. The most common causes for reoperation were implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants., Conclusions: To our knowledge, this study is the largest long-term follow-up of nonambulatory patients with CP and neuromuscular scoliosis who underwent spinal fusion. Approximately 22% of these patients required reoperation 10 years after their index surgery, primarily due to implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants. Complications and reoperations continued throughout the 10 years period after index surgery, reinforcing the need for long-term follow-up as these patients transition into adulthood., Level of Evidence: III., (© 2024.

Study Design: Modified Delphi consensus study., Objective: To develop consensus-based best practices for the care of pediatric patients who have implanted programmable devices (IPDs) and require spinal deformity surgery., Summary of Background Data: Implanted programmable devices (IPDs) are often present in patients with neuromuscular or syndromic scoliosis who require spine surgery. Guidelines for monitoring and interrogating these devices during the perioperative period are not available., Methods: A panel was assembled consisting of 25 experts (i.e., spinal deformity surgeons, neurosurgeons, neuroelectrophysiologists, cardiologists, and otolaryngologists). Initial postulates were based on a literature review and results from a prior survey. Postulates addressed the following IPDs: vagal nerve stimulators (VNS), programmable ventriculoperitoneal shunts (VPS), intrathecal baclofen pumps (ITBP), cardiac pacemakers and implantable cardioverter-defibrillators (ICD), deep brain stimulators (DBS), and cochlear implants. Cardiologist and otolaryngologist participants responded only to postulates on cardiac pacemakers or cochlear implants, respectively. Consensus was defined as ≥80% agreement, items that did not reach consensus were revised and included in subsequent rounds. A total of 3 survey rounds and 1 virtual meeting were conducted., Results: Consensus was reached on 39 total postulates across 6 IPD types. Postulates addressed general spine surgery considerations, the use of intraoperative monitoring and cautery, the use of magnetically controlled growing rods (MCGRs), and the use of an external remote controller to lengthen MCGRs. Across IPD types, consensus for the final postulates ranged from 94.4% to 100%. Overall, experts agreed that MCGRs can be surgically inserted and lengthened in patients with a variety of IPDs and provided guidance for the use of intraoperative monitoring and cautery, which varied between IPD types., Conclusion: Spinal deformity correction surgery often benefits from the use of intraoperative monitoring, monopolar and bipolar cautery, and MCGRs. The final postulates from this study can inform the perioperative and postoperative practices of spinal deformity surgeons who treat patients with both scoliosis and IPDs., Level of Evidence: V-Expert opinion., Competing Interests: J.T.B. has consulted for Orthopediatrics Corporation, Medtronic, Inc., and Medical Devices Business Services, Inc.

To evaluate whether preoperative conversion from a gastrostomy tube (G-tube) to a gastrojejunostomy tube (GJ-tube) decreases short-term postoperative aspiration pneumonia and gastrointestinal complications in children with neuromuscular scoliosis. We conducted a retrospective chart review from January 2006 to October 2021 of pediatric patients who had neuromuscular scoliosis and were fed with a G-tube before spinal fusion. Eligible patients were divided into two groups based on whether they were converted to a GJ-tube preoperatively. Preoperative characteristics and 30-day postoperative outcomes were compared between groups using Chi-square tests. Of 261 eligible patients, 205 were converted to a GJ-tube, while 56 underwent spinal fusion with a G-tube. Common complications following G-tube to GJ-tube conversion were feeding intolerance (25.2%), GJ-tube malfunction (17.7%), and at least one episode of vomiting (17.4%). Within 30 days of discharge, 12.5% of GJ-tube patients and 11.5% of G-tube patients experienced aspiration pneumonia (P = 0.85). The GJ-tube group received postoperative tube feeds 7 hours earlier than the G-tube group on average (51.6 h vs. 44.5 h, P = 0.02). Within 30 days of discharge, one (0.5%) patient from the GJ-tube group died of gastrointestinal complications unrelated to conversion and two (3.6%) patients in the G-tube group died from aspiration pneumonia (P = 0.12). Results suggest that there were no appreciable differences in outcomes between patients converted to a GJ-tube preoperatively compared to those who continued to use a G-tube. However, preoperative characteristics indicate that a higher number of complex patients were converted to a GJ-tube, indicating potential selection bias in this retrospective sample.

Purpose: The Law Of Diminishing Returns (LODR) has been demonstrated for traditional growing rods, but there is conflicting data regarding the lengthening behavior of Magnetically Controlled Growing Rods (MCGR). This study examines a cohort of patients with early-onset scoliosis (EOS) with rib-to-spine or rib-to-pelvis-based MCGR implants to determine if they demonstrate the LODR, and if there are differences in lengthening behaviors between the groups., Methods: A prospectively collected multicenter EOS registry was queried for patients with MCGR with a minimum 2-year follow-up. Patients with rib-based proximal anchors and either spine- or pelvis-based distal anchors were included. Patients with non-MCGR, unilateral constructs, < 3 lengthenings, or missing > 25% datapoints were excluded. Patients were further divided into Primary-MCGR (pMCGR) and Secondary-MCGR (sMCGR)., Results: 43 rib-to-spine and 31 rib-to-pelvis MCGR patients were included. There was no difference in pre-implantation, post-implantation and pre-definitive procedure T1-T12 height, T1-S1 height, and major Cobb angles between the groups (p > 0.05). Sub-analysis was performed on 41 pMCGR and 19 sMCGR rib-to-spine patients, and 31 pMCGR and 17 sMCGR rib-to-pelvis patients. There is a decrease in rod lengthenings achieved at subsequent lengthenings for each group: rib-to-spine pMCGR (rho = 0.979, p < 0.001), rib-to-spine sMCGR (rho = 0.855, p = 0.002), rib-to-pelvis pMCGR (rho = 0.568, p = 0.027), and rib-to-pelvis sMCGR (rho = 0.817, p = 0.007). Rib-to-spine pMCGR had diminished lengthening over time for idiopathic, neuromuscular, and syndromic patients (p < 0.05), with no differences between the groups (p > 0.05). Rib-to-pelvis pMCGR neuromuscular patients had decreased lengthening over time (p = 0.01), but syndromic patients had preserved lengthening over time (p = 0.65)., Conclusion: Rib-to-spine and rib-to-pelvis pMCGR and sMCGR demonstrate diminished ability to lengthen over subsequent lengthenings., (© 2023.

Purpose: Early-onset scoliosis (EOS) is often treated with magnetically controlled growing rods (MCGR) which can be lengthened with a magnetic external remote control (ERC). Many individuals with EOS have concomitant medical conditions which are managed with other implanted programmable devices (IPD). Some providers are concerned that the magnetic field generated during MCGR lengthening may interfere with other IPD, such as ventriculoperitoneal shunts (VPS), intrathecal baclofen pumps (ITBP), vagal nerve stimulators (VNS), and cochlear implants (CI). The aim of this study was to evaluate the safety of MCGR lengthenings in patients with EOS and other IPD., Methods: This single-center, single-surgeon case series followed 12 patients with 13 IPD as they underwent treatment with MCGR. Post MCGR lengthening, monitoring of patient symptoms, and interrogation of IPD were conducted to evaluate for magnetic interference., Results: After 129 MCGR lengthenings, post-lengthening VPS interrogation found 2 instances of potential interference in settings (both in Medtronic Strata shunts); however, no pre-lengthening interrogation was completed to confirm if these changes occurred prior to or during the lengthening procedure. ITBP interrogation found no changes, and there were no patient-reported adverse effects related to VNS or CI function., Conclusion: It is safe and effective to utilize MCGR in patients with IPD. However, the possibility of magnetic interference must be considered, particularly in individuals with VPS. We recommend approaching with the ERC from a caudal direction to minimize potential interference and all patients be monitored during treatment. If possible, IPD settings should be assessed pre-lengthening, confirmed afterwards and readjusted if necessary., Level of Evidence: Level IV., (© 2023.

Background: Acute hematogenous osteomyelitis (AHO) is a relatively common condition in children, and identifying the offending pathogen with blood or tissue cultures aids in diagnosis and medical management while reducing treatment failure. Recent 2021 AHO clinical practice guidelines from the Pediatric Infectious Disease Society recommend obtaining routine tissue cultures, particularly in cases with negative blood cultures. The purpose of this study was to identify variables associated with positive tissue cultures when blood cultures are negative., Methods: Children with AHO from 18 pediatric medical centers throughout the United States through the Children's ORthopaedic Trauma and Infection Consortium for Evidence-based Study were evaluated for predictors of positive tissue cultures when blood cultures were negative. Cutoffs of predictors were determined with associated sensitivity and specificity., Results: One thousand three children with AHO were included, and in 688/1003 (68.6%) patients, both blood cultures and tissue cultures were obtained. In patients with negative blood cultures (n=385), tissue was positive in 267/385 (69.4%). In multivariate analysis, age ( P <0.001) and C-reactive protein (CRP) ( P =0.004) were independent predictors. With age >3.1 years and CRP >4.1 mg/dL as factors, the sensitivity of obtaining a positive tissue culture when blood cultures were negative was 87.3% (80.9-92.2%) compared with 7.1% (4.4-10.9%) if neither of these factors was present. There was a lower ratio of methicillin-resistant Staphylococcus aureus in blood culture-negative patients who had a positive tissue culture 48/188 (25.5%), compared with patients who had both positive blood and tissue cultures 108/220 (49.1%)., Conclusion: AHO patients with CRP ≤ 4.1 mg/dL and age under 3.1 years are unlikely to have clinical value from tissue biopsy that exceeds the morbidity associated with this intervention. In patients with CRP > 4.1 mg/dL and age over 3.1 years, obtaining a tissue specimen may add value; however, it is important to note that effective empiric antibiotic coverage may limit the utility of positive tissue cultures in AHO., Level of Evidence: Level III-Retrospective comparative study., (Copyright © 2023 Wolters Kluwer Health, Inc.

Background: There is limited information on the presentation and management of upper extremity septic arthritis (UESA) in children. Our purpose was to report on the characteristics and short-term treatment outcomes of pediatric UESA from a multicenter database., Methods: Patients with UESA were identified from a multicenter retrospective musculoskeletal infection database. Demographics, laboratory tests, culture results, number of surgeries, and complications were collected., Results: Of 684 patients with septic arthritis (SA), 68 (10%) patients had UESA. Septic arthritis was most common in the elbow (53%), followed by the shoulder (41%) and wrist (4%). The median age at admission was 1.7 years [interquartile range(IQR, 0.8-8.0 y)] and 66% of the cohort was male. Blood cultures were collected in 65 (96%) patients with 23 (34%) positive results. Joint aspirate and/or tissue cultures were obtained in 66 (97%) patients with 49 (72%) positive results. Methicillin-sensitive Staphylococcus aureus (MSSA) was the most common causative organism overall, but Streptococcus was the most common pathogen in the shoulder. Sixty-six (97%) patients underwent irrigation and debridement, with 5 (7%) patients requiring 2 surgeries and 1 patient (1%) requiring 3 surgeries. The median length of stay was 4.9 days (IQR, 4.0-6.3 d). Thirty-one (46%) children had adjacent musculoskeletal infections and/or persistent bacteremia. No patients experienced venous thromboembolism, and 4 patients with associated osteomyelitis experienced a musculoskeletal complication (3 avascular necrosis, 1 pathologic fracture). One child had re-admission and 3 children with associated osteomyelitis had a recurrence of UESA. Comparison between elbow and shoulder locations showed that children with septic arthritis of the shoulder were younger (4.6 vs. 1.0 y, P =0.001), and there was a difference in minimum platelet count (280 vs. 358 ×10 9 cells/L, P =0.02)., Conclusions: UESA comprises 10% of cases of septic arthritis in children. The elbow is the most common location. Shoulder septic arthritis affects younger children. MSSA is the most common causative organism in UESA, but Streptococcus is common in shoulder septic arthritis. Irrigation and debridement result in excellent short-term outcomes with a low complication rate.

Purpose: Operative and postoperative management of early onset scoliosis (EOS) patients with programmable implanted devices has not been well characterized in the literature. The aim of this study was to describe current practices for pediatric spine surgeons who operate on patients with these devices., Methods: An electronic survey was distributed to 167 pediatric spine surgeons between January and March of 2021. The survey queried participants on operative and postoperative management of patients with the following implanted devices: vagal nerve stimulators, ventriculoperitoneal shunts, intrathecal baclofen pumps, pacemakers, and cochlear implants. Descriptive statistics were used to assess survey data., Results: Fifty-three respondents (31.7% response rate) with a mean 16.5 (SD 12.0) years in practice completed the survey. Depending on the type of device present, surgeons report changing their operative plan anywhere from 28.6 to 60.1% of the time when inserting magnetically controlled growing rods. Most respondents reported performing transcranial motor evoked potentials (80.0-98.0%) and monopolar cautery (70.0-92.9%) across implanted devices. Only 10% (n = 5) of surgeons reported complications related to operative and/or postoperative management of these patients. No complications were related to cautery, neuromonitoring, or surgical placement of MCGRs., Conclusions: This study demonstrates variation in operative and postoperative management of these patients with various programmable implanted devices. Much of this inconsistency in practice is likely due to decades old case reports, constantly changing device manufacturer recommendations, and/or published simulation studies. Reported heterogeneity in management across surgeons necessitates development of published guidelines regarding proper operative and postoperative management of patients with EOS and implanted devices., (© 2022.

Background: As the first wave of the COVID-19 pandemic stabilized and resources became more readily available, elective surgery was reinitiated and hospitals realized that there was little guidance on how to prioritize elective cases., Methods: A prioritization tool was formulated based on clinically relevant elements and previous literature. Nine pediatric orthopaedic surgeons from North American institutions evaluated 25 clinical scenarios on 2 occasions separated in time. Intra-rater and inter-rater reliability were calculated [intraclass correlation coefficient (ICC)]. Surgeons also ranked the importance of each element and how confident they were with scoring each factor., Results: Intra-rater ICC for total score showed good to excellent consistency; highest at 0.961 for length of stay (LOS) and lowest at 0.705 for acuity. Inter-rater ICC showed good to excellent agreement for American Society of Anesthesiologists score, LOS, duration of surgery, and transfusion risk and moderate agreement for surgical acuity and personal protective equipment (PPE) use. Transfusion risk and duration of surgery were deemed least important, and surgeons were least confident in scoring PPE and transfusion risk. Based on findings, the novel Elective-Pediatric Orthopedic Surgical Timing (E-POST) score for prioritizing elective cases was developed, consisting of 5 factors: surgical acuity, global health status, LOS, duration of surgery, and PPE requirement., Conclusions: The E-POST numeric total score or subscore may help objectively prioritize elective cases during a global crisis., Level of Evidence: Level V., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: Standard treatment for skeletally immature adolescents with moderate Adolescent Idiopathic Scoliosis (AIS) is a full-time spinal orthosis. However, adherence to full-time wear (≥ 18 h/day) is often challenging for these patients. Nighttime bracing is an alternative option that may improve patient adherence and/or satisfaction. This systematic review and meta-analysis assessed the effectiveness of nighttime bracing in patients with AIS., Methods: A systematic review of studies evaluating nighttime bracing was performed. PubMed, Medline, Embase, CINAHL and Cochrane library databases were searched (01/1975-03/2020); two reviewers assessed eligibility. Eligible articles were peer reviewed, in English, and reported outcomes for patients who met Scoliosis Research Society (SRS) criteria. The primary outcome was curve progression ≥ 6°. Pooled progression rates were calculated from random effects meta-analyses with inverse-variance weights; 95% CIs were calculated., Results: Nine studies (n = 595) were included. The overall pooled progression rate to ≥ 6° was 40.7% (95% CI: 30.4-51.5%). The pooled progression rate to surgical magnitude was 24.8% (95% CI: 4.5-53.6%). The most successful outcomes were in subjects with thoracolumbar/lumbar curves and subjects who initiated bracing at Risser 1/2 (pooled progression rates were 27.8% (95% CI: 17.0-40.0%) and 16.5% (95% CI: 11.7-21.8%), respectively). Univariate sub-analyses were conducted due to sample sizes., Conclusions: Progression rates in patients with primary thoracolumbar/lumbar curves and in patients who initiated nighttime bracing at Risser 1/2 were comparable to published progression rates for full-time bracing, indicating that nighttime bracing may be equally effective for these patients. However, the strength of these conclusions is limited by the sample size and the overall quality of included studies., (© 2021. Scoliosis Research Society.)

Background: Pediatric musculoskeletal infection (MSKI) is a bacterial infection of the bone, joint, and/or muscle that can be difficult to diagnose. The Kocher and Caird algorithms were developed to distinguish septic arthritis (SA) from transient synovitis (TS) in the hip. These algorithms have been applied to all patients presenting with painful, swollen monoarticular joints regardless of suspicion for SA. The aim of this analysis was to assess the test performance of Kocher and Caird to distinguish MSKI among all pediatric patients presenting with monoarticular joint pain. A secondary aim was to validate the original algorithms., Methods: We conducted a secondary analysis of a prospective cohort study evaluating the test performance of procalcitonin for suspected SA in a pediatric emergency department. Patients aged 0 to 16 years old who presented with a painful or swollen monoarticular joint were considered for enrollment. We compared the test performance of the traditional algorithms in an expanded population of MSKI versus alternate joint pain using sensitivity, specificity, and area under the curve (AUC). As a sensitivity analysis, missing data for predictors like temperature, erythrocyte sedimentation rate, C-reactive protein, and inability to bear weight were multiply imputed using the Stata program, mi impute, for changed equations., Results: The Caird algorithm had better test performance compared to the Kocher in all populations. Both algorithms were most discriminative in comparing SA to TS in all joints (AUC: 0.84 Caird and 0.75 Kocher). However, the Caird criteria performed almost as well discriminating MSKI from other causes of monoarticular joint pain in all joints (AUC: 0.79; 95% confidence interval: 0.72, 0.85) and nonhip joints (AUC: 0.80; 95% confidence interval: 0.71, 0.88)., Conclusion: Based on the findings of this study, it is clinically reasonable to apply the Caird algorithm to pediatric patients presenting with monoarticular joint pain of medium and large joints such as the knee, ankle, shoulder, elbow, and wrist, in addition to the hip., Level of Evidence: Level III-retrospective study of novel applications of SA algorithms., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Objectives: Septic arthritis (SA) is responsible for 20% of pediatric musculoskeletal infections (MSKI) and can have significant consequences. Early detection of SA is critical, and procalcitonin (PCT) has emerged as a promising biomarker. This study assessed the test performance of PCT and traditional biomarkers for suspected SA., Methods: We conducted a prospective study at two pediatric emergency departments (ED). Data collected measured serum levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC) count, and PCT. Box and whisker plots were generated to compare the of the biomarkers by positive MSKI or a non-MSKI diagnosis. The diagnostic performance of biomarkers was examined using the area under the receiver operating characteristic curve (AUC), and optimal cut -points were identified using the Liu method., Results: Procalcitonin performed reasonably well for detection of MSKI (AUC, 0.72; confidence interval [95% CI], 0.59-0.84). However, CRP and ESR performed better (AUC, 0.88 and 0.78, respectively). White blood cell count was not predictive of MSKI. Patients with a PCT value >0.1 ng/mL, ESR values >19.5 mm/h, and a temperature higher than 99.0°F were more than twice as likely to have acute MSKI. A high CRP level was most predictive of acute MSKI, and patients with levels >2.38 mg/dL were 3.5 times more likely to have acute MSKI., Conclusions: Procalcitonin is a potential biomarker for the clinical differential of MSKI in the pediatric ED. Additional research is warranted to establish the optimal diagnostic level for PCT, to increase sample size, and to examine any impact on cost., Competing Interests: Disclosure: The authors declare no conflict of interest and no financial relationships relevant to this article., (Copyright © 2020 Wolters Kluwer Health, Inc.

Background: One of the most common pediatric fractures is a midshaft both bone forearm fracture. The preferred nonoperative treatment is cast immobilization for 6 to 8 weeks; however, 4% to 8% refracture within 6 months. There are no comparative studies evaluating the efficacy of bracing after cast immobilization. We hypothesized that children treated with prolonged functional bracing would have a lower rate of refracture than casting alone or short-term bracing., Methods: This is a retrospective review of children younger than 15 years of age treated nonoperatively following radius and ulnar shaft fractures treated at 3 tertiary pediatric hospitals. We excluded distal radius/ulna fractures, isolated fractures of the radius/ulna, and fractures near the elbow. Logistic regression analysis on casting plus functional bracing was run to determine if age, translation, or the number of days in brace were associated with refracture. The incidence of refracture was compared between groups., Results: A total of 1549 patients were screened and 426 were included in the study [111 casting only (CO), 259 casting plus functional brace <8 wk (CFB <8 wk), 56 casting plus functional brace ≥8 wk (CFB ≥8 wk)]. In comparing the groups, CO was the youngest (4.4 y vs. 6.3 and 8.4 y). The initial translation and angulation of the radius and ulna were significantly greater in the CFB ≥8 weeks group. Regression analyses shows no association between refracture and initial fracture characteristics including age, translation, or the number of days in brace. The CO group had 3 refractures (2.7%), the CFB <8 weeks group had 13 (5%) and the CFB ≥8 weeks group had 1 (1.8%); demonstrating no statistical significance., Conclusion: Extended fracture bracing, following a period of cast immobilization, did not lead to a statistically significant difference in refracture rate. Contrary to previous cases series, the benefit of bracing seems nominal. Larger, prospective studies are needed to better understand targets for treatment., Level of Evidence: This is the first level III retrospective comparison study of its kind., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: Distal radius fractures (DRFs) are the most common pediatric orthopaedic fracture, of which 20% are displaced injuries. Displaced metaphyseal DRFs are often treated with sedated or anesthetized reduction. The necessity of reduction treatment of displaced fractures to achieve good clinical outcomes is unclear. The purpose of this investigation was to determine the treatment preferences for DRFs among pediatric orthopaedic surgeons and to determine whether they were uncertain enough in their decisions to randomize treatment., Methods: Twenty-eight DRF scenarios in children aged 3 to 10 years were constructed in an electronic survey to represent a spectrum of age, angulation in sagittal and coronal planes, and displacement. The survey was disseminated to the full membership of the Pediatric Orthopaedic Society of North America (POSNA). Respondents could select either a treatment of (a) attempt anatomic reduction with sedation or (b) nonsedated immobilization. Respondents also denoted whether they would be willing to randomize the treatment of each injury scenario. Patient, fracture, and surgeon characteristics were analyzed to develop predictors of treatment recommendations and willingness to randomize treatment., Results: A total of 319 surgeons responded (23% of POSNA membership). Respondents were a characteristic representation of POSNA membership (well distributed by years in practice, 78% academic, 91% whose work is >80% pediatrics, and 84% work with residents). Predictors of sedated reduction were complete displacement [odds ratio (OR), 9.23; 95% confidence interval (CI), 2.27-37.51; P=0.002] and coronal angulation (per 1-degree increase, OR, 1.09; 95% CI, 1.02-1.17; P=0.016), Willingness to randomize was inversely related to larger coronal plane angulation (per 1-degree increase, OR, 0.96; 95% CI, 0.93-0.99; P=0.01). A majority of surgeons were willing to randomize 7 of the 8 scenarios involving complete displacement and shortening, and >64% of surgeons were willing to randomize 5 of these 8 scenarios., Conclusions: POSNA members recommend sedated reduction of DRFs primarily based on existence of complete displacement. Although most completely displaced DRFs would undergo reduction, most surgeons would be willing to randomize the treatment of these injuries. This suggests that most POSNA members do not know whether their recommended treatment for displaced DRFs is necessary or correct. This survey establishes the groundwork for a randomized, prospective trial comparing nonsedated immobilization with sedated/anesthetized reduction in the treatment of displaced pediatric DRFs., Levels of Evidence: Level II-survey study.

Background: Isolated pediatric femur fractures have historically been treated at local hospitals. Pediatric referral patterns have changed in recent years, diverting patients to high volume centers. The purpose of this investigation was to assess the treatment location of isolated pediatric femur fractures and concomitant trends in length of stay and cost of treatment., Methods: A cross-sectional analysis of surgical admissions for femoral shaft fracture was performed using the 2000 to 2012 Kids' Inpatient Database. The primary outcome was hospital location and teaching status. Secondary outcomes included the length of stay and mean hospital charges. Polytrauma patients were excluded. Data were weighted within each study year to produce national estimates., Results: A total of 35,205 pediatric femoral fracture cases met the inclusion criteria. There was a significant shift in the treatment location over time. In 2000, 60.1% of fractures were treated at urban, teaching hospitals increasing to 81.8% in 2012 (P<0.001). Mean length of stay for all hospitals decreased from 2.59 to 1.91 days (P<0.001). Inflation-adjusted total charges increased during the study from $9499 in 2000 to $25,499 in 2012 per episode of treatment (P<0.001). Total charges per hospitalization were ∼$8000 greater at urban, teaching hospitals in 2012., Conclusions: Treatment of isolated pediatric femoral fractures is regionalizing to urban, teaching hospitals. Length of stay has decreased across all institutions. However, the cost of treatment is significantly greater at urban institutions relative to rural hospitals. This trend does not consider patient outcomes but the observed pattern appears to have financial implications., Level of Evidence: Level III-case series, database study.

Background: Limb deformities in ambulatory children with cerebral palsy (CP) are common. The natural history of lower extremity deformities is variable and the impact on gait is managed with many treatment modalities. Effective interventions must consider the underlying pathophysiology, patient-specific goals, and incorporate objective outcome assessment. Evaluation and treatment include observation, tone management multilevel orthopaedic surgery to address muscle contractures and bony deformities, and the use of gait analysis for preoperative and postoperative assessment., Methods: A PubMed search of the orthopaedic literature for studies published between January 2016 and February 2019 was performed. Eligible abstracts included the use of 3-dimensional instrumented gait analysis in the evaluation and treatment of the lower extremities in ambulatory children with CP. Seven hundred twenty abstracts were reviewed, with 84 papers identified as eligible, of which 45 full manuscripts were included for detailed review., Results: The review summarized recent advances regarding the treatment of torsional alignment, knee deformities and clinical gait evaluation with visual assessment tools compared with instrumented gait analysis., Conclusions: Gait analysis of ambulatory children with CP remains essential to evaluation and surgical decision-making. Promising results have been reported with the goal of maintaining or reaching a higher level of function and increased endurance., Level of Evidence: Level IV-literature review.

Objective: Adequate resources are required to rapidly diagnose and treat pediatric musculoskeletal infection (MSKI). The workload MSKI consults contribute to pediatric orthopaedic services is unknown as prior epidemiologic studies are variable and negative work-ups are not included in national discharge databases. The hypothesis was tested that MSKI consults constitute a substantial volume of total consultations for pediatric orthopaedic services across the United States., Study Design: Eighteen institutions from the Children's ORthopaedic Trauma and Infection Consortium for Evidence-based Study (CORTICES) group retrospectively reviewed a minimum of 1 year of hospital data, reporting the total number of surgeons, total consultations, and MSKI-related consultations. Consultations were classified by the location of consultation (emergency department or inpatient). Culture positivity rate and pathogens were also reported., Results: 87,449 total orthopaedic consultations and 7,814 MSKI-related consultations performed by 229 pediatric orthopaedic surgeons were reviewed. There was an average of 13 orthopaedic surgeons per site each performing an average of 154 consultations per year. On average, 9% of consultations were MSKI related and 37% of these consults yielded positive cultures. Finally, a weak inverse monotonic relationship was noted between percent culture positivity and percent of total orthopedic consults for MSKI., Conclusion: At large, academic pediatric tertiary care centers, pediatric orthopaedic services consult on an average of ~3,000 'rule-out' MSKI cases annually. These patients account for nearly 1 in 10 orthopaedic consultations, of which 1 in 3 are culture positive. Considering that 2 in 3 consultations were culture negative, estimating resources required for pediatric orthopaedic consult services to work up and treat children based on culture positive administrative discharge data underestimates clinical need. Finally, ascertainment bias must be considered when comparing differences in culture rates from different institution's pediatric orthopaedics services, given the variability in when orthopaedic physicians become involved in a MSKI workup., Competing Interests: Funding for the creation of this database was provided by the Pediatric Orthopaedic Society of North America (POSNA) through a directed research. Many members of the CORTICES are likewise active members of POSNA. The CORTICES Group has no other competing interests.

Background: Implants are commonly used to stabilize proximal femoral osteotomies in children with cerebral palsy (CP). Removal of implants is common practice and believed to avoid infection, fracture, or pain that might be associated with retained hardware. There is little evidence to support a prophylactic strategy over a reactive approach based on symptoms. The aim of this study was to compare the outcomes of prophylactic and reactive approaches to removal of proximal femoral implants in children with CP., Methods: An intention-to-treat model was used to compare 2 institutions that followed a prophylactic (within ∼1 y) and reactive (following complication/symptoms) approach to hardware removal, respectively. Patients with CP who had femoral implants placed at or before age 16, and had ≥2-year postsurgical follow-up were included. Demographics, surgical details, reasons for removal, and complications were recorded. χ and t tests were used., Results: Six hundred twenty-one patients (prophylactic=302, reactive=319) were followed for an average of 6 years (range, 2 to 17 y). Two hundred eighty-seven (95%) implants were removed in the prophylactic group at 1.2 years. In the reactive group, 64 (20%) implants were removed at an average of 4.2 years. Reasons for removal included pain; infection; fracture; or for repeat reconstruction. The rate of unplanned removals due to fracture or infection was higher in the reactive group (4.7% vs. 0.7%, P=0.002), but there was no difference in the rate of complications during/after removal between the 2 groups (1.7% vs. 3.1%; P=0.616). No specific risk factor associated with unplanned removal could be identified; but children under 8 years old seemed more likely to undergo later removal (odds ratio 1.98; 95% confidence interval, 0.99-3.99)., Conclusions: Eighty percent of patients in the reactive removal strategy avoided surgery. This group did have a 4% higher rate of fracture or infection necessitating unplanned removal but these were successfully treated at time of removal with no difference in complication rates associated with removal between both groups. One would need to remove implants from 25 patients to avoid 1 additional complication, providing some support for a reactive approach to removal of proximal femoral implants in this population., Level of Evidence: Level III-therapeutic.

Purpose: Clinical changes are best evaluated with standardized, validated outcomes, including both patient-reported outcome measures and surgeon-reported outcome measures (PROMs and SROMs). The purpose of this study was to describe the spectrum of outcome measures used in pediatric orthopaedic publications over the past 10 years and to determine the proportion that are in fact age-appropriate, validated, and appropriately applied in terms of condition and population., Methods: The Journal of Bone and Joint Surgery, The Bone and Joint Journal, Journal of Pediatric Orthopaedics A and B, and Journal of Children's Orthopaedics were systematically searched for studies including children aged 18 and below, over a 10-year period from January 2005 to December 2014. Economic evaluations, letters, editorials, review articles, and clinical guidelines were excluded. SROMs and PROMs used were extracted, as were details on subject age and condition for which they were used. Each outcome scale was assessed for validity, and the proportion of scales used appropriately was calculated. Cochrane-Armitage test of trend was used to determine changes in PROM and SROM utilization over the study period., Results: A total of 4614 articles were identified, of which 2251 met inclusion and exclusion criteria. In total, 259 (11.5%) of studies used a PROM, whereas 326 (14.5%) used a SROM. A total of 230 different outcome scales were identified; 115 were patient reported and 115 were surgeon reported. However, only 18.7% of SROMs and 38.3% of PROMs were applied to an age and disease-appropriate demographic. Overall, there was a significant increase in the overall utilization of PROMs during the study period (P=0.004), but no corresponding increase in pediatric-validated PROMs (P=0.164). SROM utilization did not significantly change over the study period (P=0.337)., Conclusions: Within the field of pediatric orthopaedics, an expansive variety of outcome scales are used, many of which have not been validated in children. Improved uniformity in reporting of outcomes and use of disease and age-validated outcomes scales is essential to improve multicenter research collaboration and data quality to generate appropriate evidence-based conclusions and treatment strategies in pediatric orthopaedics., Level of Evidence: Level IV-systematic review.

All patients with hypertonic cerebral palsy undergoing Bernese periacetabular osteotomy (PAO) between 2005 and 2014 were reviewed. Clinical and radiographic parameters, including the cerebral palsy hip classification and anterior and posterior wall indices were collected to assess acetabular reorientation. Twenty (83%) of 24 procedures involved the correction of posterolateral acetabular insufficiency and were 'anteverting PAOs'. All 20 experienced improvements in radiographic indices. Eleven (58%) of 19 PAOs in ambulatory patients were performed in the setting of other multilevel orthopedic surgery. The anteverting PAO is successful in correcting the posterolateral acetabular insufficiency present in spastic hip dysplasia, and can be performed in conjunction with a single-event multilevel surgery.

The extensor mechanism of the knee-consisting of the four muscles of the quadriceps, the quadriceps tendon, the patella, and the patellar ligament-is essential for lower extremity function during both standing and ambulation. The presence of articular cartilage and growing physes in the pediatric knee, coupled with the generation of significant tensile force, creates an opportunity for pathology unique to the pediatric population.Tibial tubercle fractures and patella injuries are quite rare, and even pediatric-trained orthopaedic surgeons may not be exposed to these injuries on a regular basis. It is the intent of this article to discuss the current literature regarding the mechanism of injury, diagnostic workup, classification, indications for surgical versus non-surgical management, and techniques for operative management for both tibial tubercle and patella (transverse and sleeve) fractures., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Purpose: The aim of this study was to elucidate developmental dysplasia of the hip (DDH) diagnosis and treatment preferences among members of the Pediatric Orthopaedic Society of North America (POSNA) and European Paediatric Orthopaedic Society (EPOS)., Methods: A 54-question survey on DDH diagnosis and treatment preferences was distributed to POSNA and EPOS members. Descriptive statistics were performed., Results: A total of 459 responses were analyzed. Ultrasound was the preferred modality for diagnosing DDH in infants less than six months old; few surgeons preferred radiographs. In all, 57% of POSNA members had radiology technicians perform ultrasounds, only 7% of EPOS members did. The percent coverage defining a dislocated hip varied greatly, the most frequent response being < 20% for POSNA and < 40% for EPOS members. Pavlik harnesses were the most popular harness/brace, used by 90% of POSNA and 71% of EPOS members. POSNA members were more likely than EPOS members to use a rigid abduction brace following initial harness/brace failure. For residual acetabular dysplasia, POSNA members were twice as likely as EPOS members to institute hip abduction bracing. Most surgeons would not perform closed reduction at less than three months of age or open reduction at less than six months of age. Most EPOS -members used traction prior to reduction; few POSNA members did. Few POSNA and EPOS members believed that reduction should be delayed until the ossific nucleus was visible., Conclusion: There is great variation in the preferred methods for diagnosing and treating DDH. This survey is the largest transcontinental survey to compile diagnostic and treatment preferences for DDH. With wide variations in practice, there is room for quality improvement.

In the United States, the rate of vehicle occupant deaths in children aged 1 to 3 years has decreased by over 50% in the past three decades. However, the Centers for Disease Control and Prevention report that motor vehicle crashes remain the leading cause of death in children aged 1 to 17 years. Parental compliance with child safety seats is poor, with up to 99% of children in certain age groups improperly restrained. Epidemiologic data support the proper use of automobile restraint systems to save lives. When appropriate restraint systems (based on age and weight) are used, a significant decrease occurs in the rates of mortality and serious injury. Legislation and public service campaigns can increase awareness regarding appropriate use of automobile restraint systems to decrease pediatric injury and fatality rates. Fluency and awareness, rather than cost, have been found to be the main reasons for improper use of automobile restraint systems; appropriately targeted education programs should continue to be developed. Physicians are optimally poised to educate patients and parents about automobile safety.
