Kevin Smit

Investigator, CHEO Research Institute

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

Research Projects

  1. Risk factors associated with prevalent vertebral fractures in Duchenne muscular dystrophy


    Readily measurable clinical variables were associated with prevalent VF in males with glucocorticoid-treated DMD. These variables may be useful to identify candidates for primary osteoporosis prevention after glucocorticoid initiation.

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


    These results suggest some preservation of spine motion in the transverse plane following VBT. This study provides initial evidence of some potential preservation of spine ROM following VBT; however, further prospective investigation of VBT is needed to assess and confirm these hypotheses.

  3. Reliability of radiographic assessment of growth modulation from anterior vertebral body tethering surgery in pediatric scoliosis


     Based on 8 individual observers, interobserver agreement ranged from good (pre-operative vertebral body heights) to moderate (4-year follow-up vertebral body heights) to poor (all wedging angles). To improve the reliability of the measurement of wedging angles, we recommend averaging the measurements of at least two observers.

  4. 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.

  5. 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.
