In 51 sarcoma resections, ICG fluorescence with an SBR cutoff of 1.67 was highly sensitive for detecting positive margins but not specific enough to replace surgeon judgment, suggesting a combined approach could reduce local recurrence.
In children with spastic hip displacement, preoperative acetabular index outperformed migration percentage as a predictor of reoperation after soft tissue release, suggesting AI should guide surgical decision-making.
In severe CP-related hip dysplasia, adding open reduction to varus derotational and pelvic osteotomy increased operative time, blood loss, and complications without improving radiographic outcomes, arguing against routine use.
Multicenter registry study finds robotic-assisted navigation achieves 97% accurate pedicle screw placement in early onset scoliosis surgery, though technical challenges like registration and calibration issues were common.
MRI analysis found a more horizontal, distally attached ACL posterolateral bundle associated with lateral femoral condyle osteochondritis dissecans, suggesting a possible role in disease pathogenesis and healing prediction.
A Delphi consensus by pediatric hand surgeons produced a new 3-tier classification for forearm deformity in multiple hereditary exostoses that showed substantially better interrater reliability than existing systems.
Surgical Outcome of Modified Woodward Procedure in Congenital Undescended Scapula.
Modified Woodward procedure for Sprengel deformity produced significant gains in shoulder motion, scapular position, and patient-reported function, even in older children and those with scoliosis.
In this large database study, youth with eating disorders had significantly higher rates of postoperative complications, especially infection, after common orthopaedic surgeries compared to peers without eating disorders.
In genu varum treated with tension-band plating, intentional overcorrection at implant removal led to more normal alignment at maturity, especially reducing tibial rebound.
Patellar tendon-lateral trochlear ridge (PT-LTR) distance ≥4.6 mm is a reliable, highly specific MRI measurement for identifying patellofemoral instability, complementing TT-TG.
In 16 pediatric patients with K-wire-associated osteomyelitis after closed fracture fixation, early aggressive debridement with antibiotic bone grafts achieved good functional outcomes despite high rates of septic arthritis and growth plate involvement.
A case report describes a rare neonatal upper limb compartment syndrome after uterine rupture managed conservatively without fasciotomy, showing normal function and growth at 10-year follow-up.
Ewing's Sarcoma in Adults: A Predictive Nomogram and Survival Analysis of a Cohort of 937 Patients.
In 937 adults with Ewing sarcoma, a new nomogram incorporating age, stage, site, size, surgery, and chemotherapy predicted disease-specific survival better than stage alone, aiding individualized prognosis.
In 50 postoperative osteogenesis imperfecta patients, a low-pressure manual noninvasive blood pressure protocol caused no fractures, supporting its safety as an alternative to arterial lines or ICU admission.
A low-cost, 3D-printed tactile Kirschner wire pinning simulator was rated favorably by pediatric orthopaedic surgeons for teaching residents pin placement, targeting, and fine motor skills outside the OR.
This technique paper describes using absorbable polydioxanone sutures to fix small osteochondral fragments in upper extremity intra-articular fractures, achieving union and joint congruity in a clinical case series.
In 22 pediatric cerebral palsy patients, THA provided durable pain relief over an average 11-year follow-up with an acceptable 22% complication rate, supporting its use in select cases of painful hip dislocation.
In 133 pediatric patients undergoing biological reconstruction after lower-limb diaphyseal tumor resection, union rates (~73%) and complication risks were similar across IMT, vascularized fibula, and combined techniques, with tibial location predicting faster, more reliable healing.
In this small retrospective case-control study, upper limb botulinum toxin plus PT was linked to worse long-term hand function, wrist extension, and supination versus PT alone, suggesting a need to reconsider BoNT-A use in unilateral cerebral palsy.
This bibliometric analysis of 25 years of DDH literature shows rapidly growing output led by North American and Western European researchers with strong international collaboration driving citation impact.
Concordance and Discordance of Intraoperative Nerve Root Findings in Brachial Plexus Birth Injury.
In 162 BPBI patients, preoperative root-level classification agreed with intraoperative findings 83% of the time, but C7-C8 injuries were frequently underestimated, arguing for careful C8 assessment and reinterpreting Horner syndrome as a severity marker rather than a sign of global injury.
In infants with successfully reduced DDH hips, Pavlik harness wear duration (average ~12 weeks) did not predict residual acetabular dysplasia at 2 years, nor did traditional risk factors.
A scoping review of published reviews on the use of bracing in scoliosis.
This scoping review of 59 studies confirms bracing reduces curve progression and surgery rates in AIS with adherence as key, but finds the evidence base largely low-quality and identifies gaps for future research.
This review summarizes current controversies in PCL injury management, including repair versus reconstruction, graft and fixation choices, and factors like posterior tibial slope affecting outcomes.
A review of ClinicalTrials.gov found 159 knee injury trials from 2021-2024, mostly adult ACL-focused studies, highlighting gaps in pediatric enrollment and injury-type diversity.
This scoping review finds that socioeconomic disadvantage, public insurance, and minority race are linked to delayed, less operative, and less adequately pain-managed pediatric extremity fracture care in the US.
An international Delphi consensus of 53 experts defines when to add lateral extra-articular procedures to ACL reconstruction, strongly recommending them for hamstring autografts in young/active patients, high-grade pivot shift, hyperextension, and skeletal immaturity.
Improving Patient Outcomes by Reducing Anemia and Bleeding in Pediatric Spine Surgery.
This review argues that multidisciplinary patient blood management, blood conservation techniques, and ERAS protocols can reduce perioperative anemia and transfusion needs in pediatric spine surgery.
This narrative review finds opioid use is common among youth athletes (28-46% lifetime use in high schoolers), with sports participation itself linked to greater risk of future opioid misuse.
Weightlifting for Children and Adolescents: A Narrative Review.
This narrative review finds youth weightlifting carries low injury risk and can improve strength, power, and body composition when programs are age-appropriate and properly supervised.
Distal Radius Physeal Bar and Ulnar Overgrowth: Indications for Treatment.
This review outlines evaluation and treatment options—from observation to bar resection, epiphysiodesis, osteotomy, and distraction osteogenesis—for distal radius physeal bars causing radioulnar growth discrepancy, guided by patient age and bar characteristics.
This review outlines osteochondritis dissecans epidemiology, uncertain etiology, imaging-based diagnosis, and treatment guided by skeletal maturity and lesion stability, noting persistent gaps in high-level evidence.
