Situation

Supraclavicular brachial plexus blockade is standard for pediatric upper limb surgery, but block duration is finite and postoperative opioid requirements introduce respiratory risks in young children. Adding perineural dexamethasone prolongs block longevity in adults, but optimal dosing and systemic metabolic safety (glycemia, inflammatory ratios) in infants and young children (3 months to 6 years) have remained undefined.

Background

While corticosteroid block adjuncts improve regional analgesia, pediatric surgeons and anesthesiologists frequently hesitate to administer perineural steroids due to theoretical concerns of neurotoxicity, prolonged motor blockade interfering with neurological examination, and systemic stress response disruption (hyperglycemia or altered neutrophil-to-lymphocyte ratios). Identifying a minimal effective dose is essential.

Assessment & Findings
  • Study Design & Methodology: Triple-blinded randomized controlled trial (NCT06086392) enrolling 90 children aged 3 months to 6 years undergoing elective hand or wrist surgery. Patients were randomized 1:1:1 to receive supraclavicular brachial plexus block with 0.2% ropivacaine combined with normal saline (control), dexamethasone 0.05 mg/kg, or dexamethasone 0.1 mg/kg. The primary endpoint was time from PACU admission to first rescue opioid administration. Secondary outcomes included FLACC pain scores, total opioid use, blood glucose, neutrophil-to-lymphocyte ratio, and motor recovery time.
  • Primary & Secondary Findings: Both dexamethasone doses significantly extended time to first rescue opioid: 19.4 +/- 2.2 hours in the 0.1 mg/kg group and 16.0 +/- 1.9 hours in the 0.05 mg/kg group versus 8.5 +/- 1.3 hours in controls (p < 0.0001). Total postoperative opioid consumption was significantly reduced in both dexamethasone cohorts, with lower FLACC pain scores across the first 12 hours.
  • Safety & Motor Recovery: Blood glucose levels, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio showed no significant differences among cohorts, and no persistent neurological deficits occurred. Although motor recovery was longer with dexamethasone, it did not interfere with post-surgical mobilization.
Recommendation & Practice Takeaway

Clinical Pearl: Low-dose perineural dexamethasone at 0.05 mg/kg nearly doubles the effective analgesia window (16 hours vs 8.5 hours) without inducing systemic hyperglycemia or inflammatory marker disruption. The 0.05 mg/kg dose provides the optimal balance for pediatric hand and wrist procedures, ensuring robust early postoperative pain control while facilitating timely motor recovery compared to higher 0.1 mg/kg dosing.

Spine Deformity & Neuromonitoring

Situation

Intraoperative neuromonitoring (IONM) using somatosensory (SSEPs) and motor evoked potentials (TcMEPs) is standard during posterior spinal fusion for adolescent idiopathic scoliosis (AIS). However, specific curve-related risk factors, trigger etiologies, and long-term 2-year radiographic outcomes following an intraoperative alert have remained incompletely characterized across large multi-center registries.

Background

Significant IONM signal loss creates acute intraoperative tension between optimizing spinal deformity correction and preventing catastrophic neurological deficits. Surgeons must decide whether an alert mandates aborting corrective maneuvers, removing instrumentation, or staging procedures, and whether experiencing an alert compromises ultimate 2-year coronal curve correction.

Assessment & Findings
  • Study Design & Methodology: Prospective multi-center database analysis of 5,206 patients with AIS undergoing spinal fusion with multimodal IONM. Alerts were defined as >=50% amplitude decrease in SSEPs and/or TcMEPs, or >10% SSEP latency increase. Demographics, curve patterns, surgical triggers, rescue interventions, and 2-year outcomes were compared between 252 patients with alerts and 4,954 without alerts.
  • Primary & Secondary Findings: IONM alerts occurred in 5% of patients overall. Alert frequency varied sharply across Lenke curve patterns: Lenke 4 (triple major) demonstrated the highest risk (8%; RR = 1.61, 95% CI: 1.15 to 2.24), whereas Lenke 5 (thoracolumbar/lumbar) carried the lowest risk (2%; RR = 0.45, 95% CI: 0.25 to 0.82). Patients with alerts presented with larger preoperative Cobb angles (mean 66.7 deg vs 56.1 deg, p < 0.001) and greater Ponte osteotomy utilization (79% vs 66%, p < 0.001). Preoperative major Cobb angle was the leading multivariable predictor of alerts (p < 0.001).
  • Trigger Events & 2-Year Correction: Intraoperative hypotension was the primary trigger event (23%), and raising MAP was the most common successful intervention (52%). Permanent neurologic deficits occurred in only 2 patients (<0.1%). Crucially, at 2-year follow-up, major Cobb angle correction did not differ between alert and non-alert cohorts (73% vs 71%, p = 0.058).
Recommendation & Practice Takeaway

Clinical Pearl: In AIS curves exceeding 65 degrees, particularly Lenke 4 patterns requiring multiple Ponte osteotomies, the intraoperative alert rate reaches 8%. Over half of all alerts resolve purely by elevating mean arterial pressure and correcting intraoperative hypotension without loss of correction. Surgeons can reassure families that experiencing a managed intraoperative alert does not compromise definitive 2-year curve correction (73% vs 71%).

Sports Medicine & Health Equity

3. Which Neighborhood-Level Metric Is Most Appropriate for Pediatric Sports Medicine Disparities Research?

Authors: Maxwell B, Raffman E, Navarro M, Rosenberg S, Merritt E et al. | Journal: Clinical Orthopaedics and Related Research (Sep 2026) | View Source / DOI

Situation

Socioeconomic disparities significantly influence pediatric orthopaedic access, particularly delay to anterior cruciate ligament reconstruction (ACLR) and subsequent secondary chondral or meniscal pathology. Researchers commonly employ either the Child Opportunity Index (COI) or the Area Deprivation Index (ADI), but their comparative sensitivity and validity in pediatric sports medicine populations have not been systematically evaluated.

Background

While the ADI captures census-level adult socioeconomic deprivation (income, housing, employment), the COI incorporates 44 pediatric-specific indicators across education, early childhood environments, and healthcare resources. Choosing an insensitive index risks under-detecting systemic access barriers and structural inequities that directly impact timely surgical intervention.

Assessment & Findings
  • Study Design & Methodology: Retrospective comparative analysis of 734 pediatric patients (<=18 years; median injury-to-surgery interval 74 days; 55% Medicaid) undergoing primary ACLR at a tertiary academic center between 2010 and 2023. COI (0 to 100, where 100 is highest opportunity) and ADI (1 to 100, where 100 is highest deprivation) were assigned by address. Multivariable regressions assessed timing of surgery and intraoperative meniscal/chondral injury while controlling for insurance and confounders.
  • Primary & Secondary Findings: COI and ADI showed moderate inverse correlation (r = -0.69, p < 0.001). After controlling for insurance and surgical delay, higher COI independently predicted shorter time to ACLR (beta = -0.56, 95% CI: -0.95 to -0.16, p = 0.006) and lower odds of irreparable meniscal tears requiring meniscectomy (OR 0.99, 95% CI: 0.98 to 0.99, p = 0.02), as well as lower odds of delay beyond 60, 90, and 180 days (p < 0.001).
  • Comparative Performance: In separate models, higher ADI associated only with binary delays beyond 60 and 90 days (p < 0.001), but failed to correlate with continuous surgical timing or secondary meniscal pathology.
Recommendation & Practice Takeaway

Clinical Pearl: The Child Opportunity Index (COI) is superior to the Area Deprivation Index (ADI) for pediatric orthopaedic health equity research, capturing both delay to surgery and risk of secondary meniscal loss. Clinical teams and health policy leaders should utilize COI metrics to pinpoint underserved pediatric populations at high risk for diagnostic delays and irreparable knee joint damage.
