Rib-on-Pelvis Deformity and Reported Pain in Neuromuscular Early-Onset Scoliosis.

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.

Unplanned return to the operating room (UPROR) occurs in 40% of MCGR patients at an average of 2 years after initial implantation.

PURPOSE: This study calculated the rates of Unplanned Return to the Operating Room (UPROR) in early-onset scoliosis patients who had no previous spine surgery and underwent Magnetically Controlled Growing Rod (MCGR) implantation. METHODS: We reviewed surgical, radiographic, and UPROR outcomes for EOS patients treated with the MCGR implant < 12 years + 11 months of age, had complete preop/postop major curve measurements, and had complete MCGR details. RESULTS: 376 patients underwent MCGR implantation at a mean age of 7.7 years (1.8-12.9). Diagnoses included 106 (28%) idiopathic, 84 (22%) syndromic, 153 (41%) neuromuscular, and 33 (9%) congenital. The mean preop-cobb was 76.7° (9-145°), and an immediate postop correction was 41% (0-84%). We found that 38% (142/376) of patients experienced an UPROR prior to the maximal actuator length being achieved. UPROR occurred at mean 2 years (3 days-5 years) after initial implantation. Of the 142 patients who experienced UPROR there were 148 complications that lead to an UPROR. The most common reason for UPROR was anchor (55/148: 37%) or MCGR implant related (33/148: 22%). Wound related (22/148:15%), Neuro related 4/148: 3%), and other (34/148: 23%) accounted for the remaining UPROR occurrences. CONCLUSION: In conclusion, the MCGR UPROR rate was 142/376 (38%) after an average of 2 years post implantation. At 2-year follow-up, only 20% of MCGR patients had experienced an UPROR. However, between 2 and 5 years, the development of an UPROR increased precipitously with only 39% of MCGR patients remaining UPROR free at 5 years post MCGR implantation. The most common reason for UPROR was related to anchor or MCGR implant-related complications. This information can be utilized to set realistic expectations about the need and timing of future surgical procedures with patients and their families.

Posterior spinal fusion for adolescent idiopathic scoliosis and the impact of postoperative intravenous dexamethasone supplementation.

Postoperative care pathways for adolescent idiopathic scoliosis patients undergoing posterior spinal fusion have demonstrated decreases in postoperative opioid consumption, improved pain control, and lead to decreased lengths of stay. Our objective was to implement postoperative steroids to reduce acute postoperative opioid consumption, pain scores, and length of stay. Dosing consisted of intravenous dexamethasone 0.1 mg/kg up to 4 mg per dose for a total of three doses at 8, 16, and 24 h postoperatively. As part of a quality initiative, we compared three cohorts of patients. The initial retrospective epidural cohort (EPI) (n = 59) had surgeon placed epidural catheters with infusion of ropivacaine 0.1% postoperatively for 18-24 h. Following an institutional change in postoperative care, epidural use was discontinued. A second cohort (n = 149), with prospectively collected data, received a surgeon placed erector spinae plane block and wound infiltration with a combination of liposomal and plain bupivacaine (LB). A third cohort (n = 168) was evaluated prospectively. This cohort received a surgeon placed erector spinae plane block and wound infiltration with liposomal and plain bupivacaine and additionally received postoperative dexamethasone for three doses (LB + D). Compared to the LB cohort, the LB + D cohort demonstrated statistically significant decreases in oral milligram morphine equivalents per kilogram at 0-24, 24-48, and 48-72 h. There was a statistically significant difference in median pain scores at 24-48 and 48-72 h in LB + D versus LB. The LB + D cohort's median length of stay in hours was significantly less compared to the LB cohort (52 h vs. 70 h, p < 0.0001). Postoperative intravenous dexamethasone was added to an established postoperative care pathway for patients undergoing posterior spinal fusion for idiopathic scoliosis resulting in decreased VAS pain scores, opioid consumption, and shorter length of stay.

Successful Implementation of Enhanced Recovery After Surgery (ERAS) in Paediatric Cardiac Surgery in Australia.

BACKGROUND & AIM: Fast-track or enhanced recovery after surgery (ERAS) is a care pathway for surgical patients based on a multidisciplinary team approach aimed at optimising recovery without increasing risk with protocols based on scientific evidence, which is monitored continuously to ensure compliance and improvement. These protocols have been shown to reduce the duration of postoperative mechanical ventilation and intensive care unit (ICU) length of stay (LOS) following paediatric cardiac surgery. We present the first structured implementation of ERAS in paediatric cardiac surgery in Australia. METHODS: All patients enrolled in the ERAS pathway between October 2019 and July 2023 were identified. Demographic and perioperative data were collected retrospectively from hospital records for patients operated before June 2021 and prospectively from June 2021. A control group (non-ERAS) was identified using propensity matching from patients who underwent similar procedures and were not enrolled in the ERAS pathway (prior to October 2019). Patients were matched for age, weight, and comprehensive Aristotle score. Outcomes of interest were duration of postoperative mechanical ventilation, ICU LOS, readmission to the ICU, hospital LOS, cardiac reintervention rate, postoperative complication rate, and number of 30-day readmissions. RESULTS: Of 1,084 patients who underwent cardiac surgery during the study period (October 2019-July 2023), 121 patients (11.2%) followed the ERAS pathway. The median age at the time of surgery was 4.8 years (interquartile range [IQR] 2.8-8.8 years). The most common procedure was the closure of atrial septal defect (n=58, 47.9%). The median cardiopulmonary bypass and cross-clamp times were 40 min (IQR 28-53.5 minutes) and 24.5 min (IQR 13-34 minutes) respectively. The majority were extubated in the operating theatre (n=108, 89.3%). The median ICU and hospital LOS were 4.5 hrs (IQR 4.1-5.6 hours) and 4 days (IQR 4-5 days) respectively. None of the patients required readmission to the ICU within 24 hrs of discharge from the ICU. Three (3) patients (2.5%) required reintervention. When compared with the non-ERAS group, the duration of postoperative mechanical ventilation, ICU and hospital LOS were significantly lower in the ERAS group. There was no significant difference in the ICU readmission rate, reintervention rate, complication rate, and number of 30-day readmissions between both groups. CONCLUSIONS: ERAS after paediatric cardiac surgery is feasible and safe in select patients with low preoperative risk. This pathway reduces the duration of postoperative mechanical ventilation, ICU and hospital LOS without increasing risks, enabling the optimisation of resources.

Aborted AIS spinal fusion due to persistent loss of IONM: which patients are at greatest risk?

PURPOSE: Determine peri-operative risk factors predictive for prematurely stopping surgery prior to completion of deformity correction due to intra-operative neuromonitoring changes. METHODS: A single institution retrospective review of adolescent idiopathic scoliosis (AIS) patients that underwent spinal fusion for curves greater than 70°. Cases aborted due to persistent loss of IONM were compared to completed cases. Demographic, radiographic, neurologic, and surgical information was reviewed. RESULTS: There were 453 total cases. Nine (9/453: (2%)) cases were aborted due to persistent loss of IONM, and 4 (4/453; (0.88%)) awoke with a neurologic deficit. Comparing to the 444 completed cases, pre-operative risk factors associated with case abortion were older age (15.3 vs. 13.8 years; p = 0.02), sex (male) (66.7% vs. 20.3%, p = 0.004), and larger cobb angles (87.6° vs. 79.2°; p = 0.01). Being male increased the risk of case abortion: 7.9X. Intraoperative risk factors associated with case abortion were combined anterior/posterior approach (ASF/PSF) (44.4% vs. 7.2%; p = 0.003) and increased index procedure EBL (1127 vs. 769 mL; p = 0.043). ASF/PSF increased the risk: 10.3X. Four (4/9;44%) of the aborted cases awoke with neurologic deficit. Motor strength returned at 2.3 days (0-18). Aborted cases returned to the OR after 12.6 ± 7.0 days (1-23) which was related to time to regain motor strength. CONCLUSION: Pre-operative risk factors for AIS case abortion due to persistent loss of IOMN are older age, males, with larger Cobb angles. Intraoperative risk factors are combined ASF/PSF and increased index procedure EBL. Independent risk factors were sex (male) and ASF/PSF which increased the risk 7.9X and 10.3X, respectively.

The effect of antibiotic-impregnated calcium sulfate beads and Medical Optimization Clinic attendance on the acute surgical site infection rate in high-risk pediatric neuromuscular and syndromic scoliosis patients.

BACKGROUND: Neuromuscular and syndromic (NMS) scoliosis patients are at higher risk of acute surgical site infections (SSIs). Despite following POSNA's endorsed consensus-based guidelines for SSI prevention, our institutional rates of acute SSI have varied dramatically. This variability drove simultaneous strategies to lower SSI rates: the creation of a preoperative Medical Optimization Clinic (MOC) and use of antibiotic-impregnated (Abx-I) calcium sulfate beads. METHODS: Patients undergoing index PSF at a single institution between 2016 and 2022 were retrospectively reviewed. Patients with ≥ 2 risk factors were included: (1) BMI < 18.5 or > 25; (2) incontinence; (3) instrumentation to pelvis; (4) non-verbal; (5) GMFCS IV/V. SSI was defined as deep infection within 90 days. We compared patients who attended MOC and received Abx-I (MOC + Abx-I) to those receiving neither intervention (control) nor a single intervention. RESULTS: 282 patients were included. The overall infection rate was 4.26%. Higher GMFCS (p = 0.0147), non-verbal status (p = 0.0048), and longer fusions (p = 0.0298) were independently associated with infection rate. Despite the MOC + Abx-I group having larger Cobb angles (88° ± 26°), higher GMFCS levels (4.5 ± 0.9), ASA class (3 ± 0.4), and more frequent instrumentation to the pelvis (85%), they had the lowest infection rate (2.13%) when compared to the control (4.2%) or single intervention groups (5.7%, 4.6%) (p = 0.9). CONCLUSION: The study examined the modern infection rate of NMS patients following the implementation of two interventions: MOC and Abx-I. Despite having higher risk factors (curves (88°), GMFCS level (4.5), ASA class (3), higher % instrumentation to the pelvis (85%)), the patients treated with both interventions demonstrated the lowest infection rate (2.13%).

Health-related quality of life and clinical outcomes for magnetically controlled growing rod patients after treatment termination.

PURPOSE: To determine the health-related quality of life (HRQoL) and clinical outcomes of children with early onset scoliosis (EOS) treated with magnetically controlled growing rods (MCGR) followed to definitive fusion (DF). METHODS: A retrospective review of EOS patients treated with MCGR and followed to DF was performed. Outcomes included HRQoL scores, radiographic, clinical, and unplanned returns to the operating room (UPROR) data collected at pre-MCGR implantation, immediately post-MCGR implantation, pre-DF, and post-DF. HRQoL scores were collected at least 6 months post-DF. RESULTS: Twenty-eight patients (57.1% females, mean age at MCGR insertion 7.19 ± 1.5 years, mean pre-MCGR Cobb 64.7° ± 17.6) met inclusion criteria. MCGR treatment resulted in an overall 30.2% improvement in coronal plane deformity following DF. The mean growth rates between MCGR implantation and pre-DF for T1-T12 height and T1-S1 length were 0.33 ± 0.23 mm/month and 0.49 ± 0.28 mm/month, respectively. Of the 28 included patients, 26 (92.9%) experienced at least one UPROR, with a total of 52 surgical complications occurring in the total cohort, representing 1.9 UPROR/patient. Interestingly, there was a decline in scores reported between post-MCGR implantation and the pre-DF time-point (N = 16, 78.2 ± 14.9 vs 69.7 ± 17.8, p = 0.02). These scores recovered post-DF, resulting in an overall unchanged HRQoL when comparing pre-MCGR to post-DF (N = 11, 79.9 ± 15.1 vs 76.7 ± 17.9, p = 0.44). CONCLUSION: While MCGR treatment achieves coronal plane deformity control and facilitates spinal growth, only 7.1% of children experienced a complication-free treatment course when followed to definitive fusion. Patients achieved modest curve correction and spinal growth, while maintaining stable HRQoL outcomes between pre-MCGR and post-DF.

Do Children With Medicaid Insurance Have Increased Revision Rates 5 Years After Posterior Spinal Fusions?

BACKGROUND: Socioeconomic disparities in musculoskeletal care are increasingly recognized, however, no studies to date have investigated the role of the insurance carrier on outcomes after posterior spinal fusion (PSF) with segmental spinal instrumentation for adolescent idiopathic scoliosis (AIS). METHODS: A US insurance dataset was queried using the PearlDiver Mariner software for all patients aged 10 to 18 undergoing PSF for a primary diagnosis of AIS between 2010 and 2020. Age, sex, geographic region, number of levels fused, and baseline medical comorbidities were queried. Complications occurring within 90 days of the index surgery were queried using the International Classification of Diseases, Ninth Revision (ICD-9) and International Classification of Diseases, 10th Revision (ICD-10) codes. Revision surgery was also queried up to 5 years after the index PSF. Categorical variables were compared using the Fisher χ 2 tests and continuous variables were compared using independent t tests. All-cause revision within 5 years was compared using the Kaplan-Meier analysis and a log-rank test. Significance was set at P -value <0.05. RESULTS: A total of 10,794 patients were identified with 9006 (83.4%) patients with private insurance and 1788 (16.6%) patients insured by Medicaid. The mean follow-up in the database was 5.36±3 years for patients with private insurance and 4.78±2.9 years for patients with Medicaid insurance ( P <0.001). Children with AIS and Medicaid insurance had a significantly higher prevalence of asthma, hypertension, and obesity. A larger percentage of children with Medicaid insurance (41.3%) underwent a ≥13-level PSF compared with privately insured children (34.5%) ( P <0.001). Medicaid patients did not experience higher odds of postoperative complications; in addition, revision surgeries occurred in 1.1% and 1.8% of patients with private insurance and Medicaid insurance, respectively at 5 years postoperatively ( P =0.223). CONCLUSION: Despite worse baseline comorbidities and longer fusion constructs, AIS patients insured with Medicaid did not have higher rates of complications or revisions at 5-year follow-up versus privately insured patients. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

An Analysis of Scoliosis in Autism Spectrum Disorder.

BACKGROUND: Children with autism/Asperger are grouped into the diagnosis of autism spectrum disorder (ASD). It remains uncertain whether children with ASD and scoliosis have radiographic and clinical outcomes similar to idiopathic scoliosis (IS) patients. METHODS: A single-center, retrospective review of a prospective scoliosis registry evaluated patients who had a posterior spinal fusion±Anterior Spinal Fusion and an underlying diagnosis of ASD between 1990 and 2021. A 2:1 match with AIS patients by age and sex was compared using demographic, radiographic, intraoperative, and SRS-22/30 variables. RESULTS: Thirty patients with ASD (63% male, mean age at surgery 14.6±2.5 y) met inclusion criteria, with a follow-up of 2.46±1.00 years. Despite no differences in curve magnitude preoperatively, patients with ASD had a higher percent correction at 2-year follow-up (66% vs. 57%, P =0.01) and improved mean curve magnitude (20±10 degrees) at 2-year follow-up compared with IS patients (27±11 degrees, P <0.01). ASD patients had less lumbar lordosis preoperatively (40±12 vs. 53±14, P <0.01), but there were no significant differences in sagittal parameters at 2-year follow-up. There were no significant differences in the rate of complications at 2-year follow-up between ASD and AIS cohorts. CONCLUSIONS: Although patients with ASD exhibited decreased lordosis compared with IS patients preoperatively, their radiographic outcomes at 2-year follow-up were the same. In addition, ASD patients maintained greater curve correction than IS patients at 2 years follow-up. LEVEL OF EVIDENCE: Prognostic retrospective study.

Increasing soft tissue depth is associated with stalling of magnetically controlled growing rods.

Background: Magnetically controlled growing rods (MCGR) represent the most used implant for the treatment of early onset scoliosis (EOS). These implants lengthen through the application of a remote magnetic field but distraction force generation has been negatively correlated with increasing soft tissue depth. Given the high rate of MCGR stalling, we proposed to investigate the impact of preoperative soft tissue depth on the rate of MCGR stalling at a minimum of 2 years following implantation. Methods: A single-center, retrospective review of prospectively enrolled children with EOS treated with MCGR was performed. Children were included if they had a minimum of 2-years follow-up after implantation and underwent advanced spinal imaging (MRI or CT) preoperatively within a year of implantation. The primary outcome was the development of MCGR stall. Additional measures included radiographic deformity parameters and gain in MCGR actuator length. Results: About 55 patients were identified with 18 having preoperative advanced imaging allowing tissue depth measurement (Mean 5.99 ± 1.9 years, 83.3% female, mean Cobb 68.6 ± 13.8°). At a mean follow-up of 46.1 ± 11.9 months, 7 patients (38.9%) experienced stalling. MCGR stalling was associated with increased preoperative soft tissue depth (21.5 ± 4.4 mm vs. 16.5 ± 4.1 mm; p = .025) and increased BMI (16.3 ± 1.6 vs. 14.5 ± 0.9; p = .007). Conclusions: Greater preoperative soft tissue depth and BMI were associated with the development of MCGR stalling. This data supports previous studies showing that the distraction capacity of MCGR diminishes with increased soft tissue depth. Further research is needed to validate these findings and their implications on the indications for MCGR implantation.

Pediatric Elbow Dislocations and Associated Fractures.

The objective was to evaluate pediatric patients with acute elbow dislocation and/or associated fracture to determine which were indicated for surgical intervention, using a single institution, Institutional Review Board (IRB) approved retrospective review of patients who presented to the Emergency Department (ED) with an acute elbow dislocation. Inclusion criteria were age ≤ 18 years, acute elbow dislocation injury, and appropriate imaging. A total of 117 patients were included 37 had a simple elbow dislocation, 80 had an associated fracture (medial epicondyle 59, lateral condyle 9, radial head/neck 7, other 5). A total of 62% (73/117) were male. The average age was 10.3 years (range 4-17). Mechanisms of injury included: falls from height/playground equipment (46), trampoline (14), and sports (57). All 37 patients with a simple elbow dislocation were successfully treated with closed reduction. Of the 80 patients with an associated fracture, 30 (38%) went on to open reduction internal fixation (ORIF). A total of 59 patients had an associated medial epicondyle fracture; 24 (41%) of whom went on to ORIF. Nine patients had an associated lateral condyle fracture, five (56%) of whom went on to ORIF. Patients with a simple elbow dislocation can be successfully treated with a closed reduction in the ED. However, 30/80 patients with an associated fracture (medial epicondyle, lateral condyle, or radial neck) required operative management.

The evolution of pre-operative SRS scores over time in patients with adolescent idiopathic scoliosis.

PURPOSE: To determine if preoperative Health Related Quality of Life (HRQoL) has declined in the past two decades for patients with Adolescent Idiopathic Scoliosis (AIS), as measured by the Scoliosis Research Society (SRS) questionnaire. METHODS: A retrospective review was conducted on AIS patients that underwent surgery at a single institution between 2002 and 2022. Patients were included if they completed an SRS questionnaire preoperatively. A multivariate linear regression was performed with the SRS domains as the dependent variables. The independent variables were surgery year, gender, race/ethnicity, BMI, Lenke type, and major Cobb angle. A second regression was performed where the SRS scores for AIS patients were dichotomized as being above or below normal based on a threshold set at two standard deviations below the mean SRS scores of a healthy adolescent population. The binary SRS scores were used as the outcome of interest in a second regression. RESULTS: A total of 1380 patients (79.2% female, mean age 14.9 ± 2.0 years old) were included for analysis. Surgery year had a negative association with Pain (coefficient = - 0.03, p < 0.0001), Activity (coefficient = - 0.02, p < 0.0001), Mental Health (coefficient = - 0.01, p < 0.0001), and Total score (coefficient = - 0.01, p < 0.0001), indicating declining HRQoL over time. Similarly, AIS patients became more likely to fall below 2SD of the healthy adolescent means in Pain (OR: 1.061, p < 0.0001), Appearance (OR: 1.023, p = 0.0301), Activity (OR: 1.044, p = 0.0197), and Total score (OR: 1.06, p < 0.0001). CONCLUSION: Over the past two decades, patients with surgical AIS have experienced a significant decline in various HRQoL domains preoperatively.

The Addition of Daytime Physiotherapeutic Scoliosis-specific Exercises to Adolescent Idiopathic Scoliosis Nighttime Bracing Reduces Curve Progression.

BACKGROUND: The effectiveness of physiotherapeutic scoliosis-specific exercises (PSSE) in addition to nighttime bracing compared with nighttime bracing alone is unknown. The purpose of this prospective comparative study was to evaluate the effectiveness of PSSE in skeletally immature patients with adolescent idiopathic scoliosis treated with nighttime bracing (PSSE group) compared with the standard of care of nighttime bracing alone (control group). METHODS: Patients with adolescent idiopathic scoliosis thoracolumbar or lumbar primary curves <35 degrees at Risser stage 0 who wore a Providence brace were prospectively enrolled into the PSSE or control group. A temperature sensor recorded the number of hours of brace wear. The PSSE group was instructed in the Schroth-based physical therapy method and a home exercise program for at least 15 minutes per day, 5 days per week, for 1 year. RESULTS: Seventy-four patients (37 PSSE, 37 controls) were followed until the final visit of skeletal maturity or surgery. The PSSE and control groups had similar baseline Cobb angles (24 vs. 25 degrees) and average hours of brace wear (8.0 vs. 7.3 h). The PSSE group had no change in curve magnitude at the final visit compared with curve progression in the control group (1 vs. 7 degrees, P <0.01). Furthermore, the PSSE group had a lower rate of curve progression >5 degrees at the final visit (14% vs. 43%, P <0.01). The PSSE group also had less conversion to full-time bracing after 1 year (5% vs. 24%, P =0.046), but differences were no longer significant at the final visit (14% vs. 27%). CONCLUSIONS: In this prospective series of patients in nighttime Providence braces, the addition of Schroth-based physical therapy reduced curve progression after 1 year and at skeletal maturity. These findings can educate motivated families interested in PSSE. LEVEL OF EVIDENCE: Level II.

The evolving stall rate of magnetically controlled growing rods beyond 2 years follow-up.

PURPOSE: Magnetically controlled growing rods (MCGR) have become the dominant distraction-based implant for the treatment of early onset scoliosis (EOS). Recent studies, however, have demonstrated rising rates of implant failure beyond short-term follow-up. We sought to evaluate a single-center experience with MCGR for the treatment of EOS to define the rate of MCGR failure to lengthen, termed implant stall, over time. METHODS: A single-center, retrospective review was conducted identifying children with EOS undergoing primary MCGR implantation. The primary endpoint was the occurrence of implant stalling, defined as a failure of the MCGR to lengthen on three consecutive attempted lengthening sessions with minimum of 2 years follow-up. Clinical and radiographic variables were collected and compared between lengthening and stalled MCGRs. A Kaplan-Meier survival analysis was conducted to assess implant stalling over time. RESULTS: A total of 48 children met inclusion criteria (mean age 6.3 ± 1.8 years, 64.6% female). After a mean 56.9 months (range of 27 to 90 months) follow-up, 25 (48%) of children experienced implant stalling at a mean of 26.0 ± 14.1 months post-implantation. Kaplan-Meier survival analysis demonstrated that only 50% of MCGR continue to successfully lengthen at 2 years post-implantation, decreasing to < 20% at 4 years post-implantation. CONCLUSION: Only 50% of MCGR continue to successfully lengthen 2 years post-implantation, dropping dramatically to < 20% at 4 years, adding to the available knowledge regarding the long-term viability and cost-effectiveness of MCGR in the management of EOS. Further research is needed to validate these findings.

Diagnosing and treating leprosy in a non-endemic setting in a national centre, London, United Kingdom 1995-2018.

BACKGROUND: Leprosy is rare in the United Kingdom (UK), but migration from endemic countries results in new cases being diagnosed each year. We documented the clinical presentation of leprosy in a non-endemic setting. METHODS: Demographic and clinical data on all new cases of leprosy managed in the Leprosy Clinic at the Hospital for Tropical Diseases, London between 1995 and 2018 were analysed. RESULTS: 157 individuals with a median age of 34 (range 13-85) years were included. 67.5% were male. Patients came from 34 different countries and most contracted leprosy before migrating to the UK. Eighty-two (51.6%) acquired the infection in India, Sri Lanka, Bangladesh, Nepal and Pakistan. 30 patients (19.1%) acquired leprosy in Africa, including 11 from Nigeria. Seven patients were born in Europe; three acquired their leprosy infection in Africa, three in South East Asia, and one in Europe. The mean interval between arrival in the UK and symptom onset was 5.87 years (SD 10.33), the longest time to diagnosis was 20 years. Borderline tuberculoid leprosy (n = 71, 42.0%), and lepromatous leprosy (n =, 53 33.1%) were the commonest Ridley Jopling types. Dermatologists were the specialists diagnosing leprosy most often. Individuals were treated with World Health Organization recommended drug regimens (rifampicin, dapsone and clofazimine). CONCLUSION: Leprosy is not a disease of travellers but develops after residence in an leprosy endemic area. The number of individuals from a leprosy endemic country reflect both the leprosy prevalence and the migration rates to the United Kingdom. There are challenges in diagnosing leprosy in non-endemic areas and clinicians need to recognise the symptoms and signs of leprosy.

Adolescent Idiopathic Scoliosis for Pediatric Providers.

Adolescent idiopathic scoliosis occurs in 2% to 3% of the adolescent population, affecting people between ages 10 and 16 years. Scoliosis onset is usually earlier in girls than in boys-generally occurring between ages 10 and 14 years for girls and 12 and 16 years for boys. The cause of idiopathic scoliosis is unknown. It is probably multifactorial. Much of the research on the etiology has focused on connective tissue abnormalities, nutritional deficiency, and genetic factors. [Pediatr Ann. 2022;51(9):e364-e369.].

Vocal cord dysfunction after pediatric cardiac surgery: A prospective implementation study.

Objective: To determine the incidence, outcomes, and evaluate diagnostic modalities for postoperative vocal cord dysfunction (VCD) following cardiothoracic surgery in children. Methods: A prospective mixed-methods study using principles of implementation science was completed. All patients undergoing surgery involving the aortic arch, ductus, or ligamentum arteriosum and vascular rings from September 2019 to December 2020 were enrolled. Patients underwent speech pathology assessment, laryngeal ultrasound, and flexible direct laryngoscopy. Results: Ninety-five patients were eligible for inclusion. The incidence of VCD ranged from 18% to 56% and varied according to procedure group. VCD occurred in 42% of neonates. Repair of hypoplastic aortic arch was associated with increased risk of VCD (57%; P = .002). There was no significant difference in duration of intubation, pediatric intensive care unit stay, or hospital stay. Forty percent children were able to achieve full oral feeding. Children with VCD were more likely to require nasogastric supplementary feeding at discharge (60% vs 36%; P = .044). Sixty-eight percent of patients demonstrated complete resolution of VCD at a median of 97 days postoperatively. Laryngeal ultrasound and speech pathology assessment combined had a sensitivity of 91% in comparison to flexible direct laryngoscopy. Conclusions: VCD occurred in one-third and resolved in two-thirds of patients at a median of 3 months following cardiac surgery. Aortic arch repair carried the highest risk of VCD. VCD adversely influenced feeding. Forty percent of patients achieved full oral feeding before discharge. VCD did not delay intensive care unit or hospital discharge. Speech pathology assessment and laryngeal ultrasound combined was reliable for diagnosis in most patients and was more patient friendly than flexible direct laryngoscopy.

Prioritizing Elective Surgical Cases During a Pandemic or Global Crisis: The Elective-Pediatric Orthopedic Surgical Timing (E-POST) Score.

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.

Implementation of a novel vocal cord dysfunction management pathway using the consolidated framework for implementation research.

Every year in Australia over a thousand children who are born with congenital heart disease require surgical intervention. Vocal cord dysfunction (VCD) can be an unavoidable and potentially devastating complication of surgery for congenital heart disease. Structured, multidisciplinary care pathways help to guide clinical care and reduce mortality and morbidity. An implementation study was conducted to embed a novel, multidisciplinary management pathway into practice using the consolidated framework for implementation research (CFIR). The goal of the pathway was to prepare children with postoperative vocal cord dysfunction to safely commence and transition to oral feeding. Education sessions to support pathway rollout were completed with clinical stakeholders. Other implementation strategies used included adaptation of the pre-procedural pathway to obtain consent, improving the process of identifying patients on the VCD pathway, and nominating a small team who were responsible for the ongoing monitoring of patients following recruitment. Implementation success was evaluated according to compliance with pathway defined management. Our study found that while there were several barriers to pathway adoption, implementation of the pathway was feasible despite pathway adaptations that were required in response to COVID-19.

Lack of in-brace x-rays in compliant AIS patients wearing full-time TLSO braces associates with failure.

BACKGROUND: In-brace correction and brace compliance with thoraco-lumbo-sacral orthotic (TLSO) braces are associated with successful treatment of adolescent idiopathic scoliosis (AIS). This paper compares patients who had consistent radiographic documentation of in-brace correction to those who did not. METHODS: All skeletally immature (Risser 0-2) patients were treated for AIS (25-45°) with full-time TLSO braces that had compliance temperature monitors. All patients wore their braces at least 12 h a day. Brace failure was defined as curve progression to a surgical magnitude (≥ 50°). All patients were followed until brace discontinuation. RESULTS: Ninety patients (F 82, M 8) with an average age of 12.1 (10.1-15.0) years, Risser grade 0 (0-2), BMI percentile 48.5 (0.0-98.8), and daily brace wear of 16.5 (12.1-21.6) h/day were treated for 24.3 (8.0-66.6) months. Patients went through 1.7 (1-4) braces on average. Forty-two out of 90 (46.7%) patients had some amount of brace time with an unknown in-brace correction, which, on average, was 66.1% of their total treatment course (11.5-100). On univariate analysis, patients that did not have a repeat in-brace x-ray with major brace adjustments or new brace fabrication tended to be more skeletally immature (Risser 0 and tri-radiate open, p = 0.028), wear more braces throughout their treatment (2.0 vs 1.4, p < 0.001), were treated for a longer period of time (27 vs 22 months, p = 0.022), and failed bracing more often (47.6% vs 22.9%, p = 0.014). CONCLUSIONS: Patients who did not have new in-brace x-rays with major brace adjustments and/or new brace fabrication were 3.1 (95% CI 1.2-7.6) times more likely to fail bracing than patients who were re-checked with new in-brace x-rays.
