Orthopaedic Surgery, Plastic Surgery, and other surgery-related research.

The Division of Pediatric Orthopaedic Surgery has published research papers in the peer-reviewed literature across the spectrum of pediatric orthopedics: from orthopedic trauma to global surgery, from basic biomechanical research to involvement in multi-center research projects on post-operative pain, education for health providers and health consumers.

Research Projects

  1. The effect of vertebral body tethering on spine range of motion in adolescent idiopathic scoliosis: a pilot study.


  2. Management and Outcomes of Clinical Scaphoid Fractures in Children


    Management of clinical scaphoid fractures at our institution was relatively uniform: nearly all patients were immobilized and less than 20% received advanced imaging. Our findings suggest a low but non-zero occult scaphoid fracture rate, discordance in radiologic interpretation, and lack of advanced imaging, providing an avenue for future prospective studies.

  3. Coronal deformity angular ratio as a predictive factor for in-brace curve correction and long-term outcome of brace treatment in adolescents with idiopathic scoliosis


    To investigate the relationship between coronal deformity angular ratio (C-DAR) and in-brace correction (IBC) and their role in predicting the long-term bracing outcome in adolescents with idiopathic scoliosis (AIS).

  4. Multidisciplinary Practice Variations of Anti-Thrombotic Strategies for Free Tissue Transfers


    There are diverse practice variations in anti-thrombotic strategies for free tissue transfers and a difference in perceived risk factors for flap failure that may affect patient management.

  5. Pediatric Acetabular Osteomyelitis Treated With Hip Arthroscopy


    This case demonstrates how hip arthroscopy can serve as an important surgical treatment modality for acetabular osteomyelitis with intraarticular extension in addition to septic arthritis of the hip.

  6. The Feasibility of Magnetic Resonance Imaging Without General Anesthesia Using the “Bundle and Scan” Technique for Infants With Sensorineural Hearing Loss


    The purpose of this study is to determine the feasibility of magnetic resonance imaging (MRI) without general anesthesia (GA) for infants being evaluated for sensorineural hearing loss (SNHL) using the bundle and scan technique.

  7. Hip Joint Preservation Surgery: What Every Orthopaedic Provider Needs to Know


    It is important for the orthopaedic surgeon to be up to date on how the hip preservation field has evolved and the steps to consider when a painful hip presents in clinic.

  8. Electronic Consultation Systems: Impact on Pediatric Orthopaedic Care


    This cross-sectional study demonstrates the effective and timely use of eConsult in pediatric orthopaedic surgery. It also shows a significant reduction in the number of in-person consultations required and demonstrates a high satisfaction rate by PCPs using the service.

  9. Bilateral Discoid Medial Menisci: A Case Report and Review of the Literature


    Bilateral discoid medial menisci are exceptionally rare and of uncertain pathoetiology. We report on a case in an active adolescent woman who presented with bilateral medial knee joint line pain.

  10. Paediatric adenotonsillectomy, part 2: considerations for anaesthesia


    The perioperative anaesthetic care of a child undergoing AT is evolving. Perioperative risk stratification is becoming less reliant on PSG as overnight pulse oximetry is an increasingly acceptable alternative. Validated paediatric questionnaires to diagnose OSA or predict critical PRAEs are being developed. These are likely to incorporate objective measures, such as overnight pulse oximetry, to improve performance of the tools. Preparation is required to address the unique airway challenges inherent in the child undergoing AT. Increased pain and sensitivity to opioid-induced respiratory depression in the child with OSA compel using a multimodal opioid-sparing analgesic technique.

  11. Outcomes After Flexor Tendon Injuries in the Pediatric Population: A 10-Year Retrospective Review


    Pediatric tendon injuries have good outcomes with no predictive factors identified. Surgical repairs performed under local anesthetic have similar outcomes without increased rates of complications, but remain underused in the pediatric population.

  12. Incidence, Risk Factors, and Mortality Associated With Orofacial Cleft Among Children in Ontario, Canada


    These findings suggest that despite decreasing incidence of OFC, children with OFC should be monitored closely for adverse health outcomes.

  13. Predictors of postoperative respiratory complications in children undergoing adenotonsillectomy


    Prediction modeling concurrently evaluating comorbidities and polysomnography metrics identified cardiac disease, airway anomaly, and young age as independent predictors of PRAEs. These findings suggest that medical comorbidity and age are more important factors in predicting PRAEs than PSG metrics in a medically complex population.

  14. Viable versus nonviable positive margins in Ewing sarcoma and associated recurrence rates: A systematic review


    This is an area where there is a paucity of evidence that needs to be rectified to ensure that ES patients are provided the highest quality of evidence-based care.
