Dr. Smit is a Pediatric Orthopedic Spine Surgeon and a Mid-Career Clinician-Scientist at CHEO. He is an Assistant Professor of Surgery at the University of Ottawa. Dr. Smit’s clinical interests include spinal deformity, complex hip pathologies, bone health, and fracture trauma. He leads our Spine Research Program and his research primarily focuses on the treatment of children with scoliosis, specifically vertebral body tethering. He is a Principal Investigator on over 10 studies at CHEO and the Site Investigator on two Health Canada Device trials for the treatment of Adolescent Idiopathic Scoliosis.
Areas of interest: Spine, Hip, Bone Health
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.
Body mass index affects outcomes after vertebral body tethering surgery
Our findings demonstrate that, as compared to normal weight and underweight patients, overweight patients did not have a statistically significant difference in intra-operative scoliosis correction or in risk of experiencing complication; however, overweight patients had a risk ratio of 4.74 for progression of scoliosis during the growth modulation phase of treatment from first erect radiographs to minimum 2-year follow-up.
The Toddler’s Fracture
Although a stable fracture with an excellent prognosis, opportunities exist to improve toddler's fractures diagnosis and treatment protocols, to optimize clinical management.
The Effects of Physical Activity on Physeal and Skeletal Development
Additional research is necessary to better define the pathoetiology of activity-mediated morphological changes, as well as to create and validate parameters for safe involvement in competitive physical activities.
Growth-preserving instrumentation in early-onset scoliosis patients with multi-level congenital anomalies
While some favorable results were found, treatment strategies allowing improved deformity correction would be valuable for this challenging population.
