Wrist buckle fractures are among the most common injuries in children. Until recently, the North American practice preference was to immobilize these injuries with casts. CHEO researchers have found, however, that children treated with a removable splint had better physical functioning, had fewer difficulties with activities, returned to sports sooner, and suffered no greater pain than those treated with casts.

  1. Poster 246: Epidemiology of Tibial Spine Fractures in Children: A National Multicenter Study


    This study represents, to our knowledge, the largest epidemiological report to date of pediatric patients with tibial spine fractures. TSFs were more common in males than females (66.1% male), and the median age at injury was 12.2 years, which falls within the commonly reported range of 8-14 years. Furthermore, only 5.8% of patients had closed regional physes, corroborating the theory that TSFs are more likely to occur in skeletally immature individuals. We believe the data presented in this study can be useful towards patient counselling by providing a comprehensive view of the common presentations of and treatment pathways for tibial spine fractures in the pediatric population.

  2. How Is Variability in Femoral and Acetabular Version Associated With Presentation Among Young Adults With Hip Pain?


    Based on the central acetabular version and femoral version as measured by Murphy, hips were grouped according to their rotational profile into four groups: unstable rotational profile: high (high acetabular version with high femoral version) or moderate (high acetabular version with normal femoral version or normal acetabular version with high femoral version); normal rotational profile (normal acetabular version with femoral version); compensatory rotational profile (low acetabular version with high femoral version or high acetabular version with low femoral version); and impingement rotational profile (low acetabular version with low femoral version): high (low acetabular version with low femoral version) or moderate (low acetabular version with normal femoral version or normal acetabular version with low femoral version). Radiographic assessments were manually performed on digitized images by two orthopaedic residents, and 25% of randomly selected measurements were repeated by the senior author, a fellowship-trained hip preservation and arthroplasty surgeon. Interobserver and intraobserver reliabilities were calculated using the correlation coefficient with a two-way mixed model, showing excellent agreement for Murphy technique measurements (intraclass correlation coefficient 0.908 [95% confidence interval 0.80 to 0.97]) and Reikerås technique measurements (ICC 0.938 [95% CI 0.81 to 0.97]). Patient-reported measures were recorded using the International Hip Outcome Tool (iHOT-33) (0 to 100; worse to best).

  3. The evolving role and technique of hip arthroscopy in children and adolescents


    Hip arthroscopy has come a long way from the initial description of the endoscopic visualization of the hip joint nearly a century ago. The development of pediatric and adolescent hip arthroscopy has largely paralleled, and trailed shortly behind, the recent growth and technical development in adult hip arthroscopy over the last twenty years. In the adult or general literature, large randomized controlled trials, observational cohorts, and national registries have made hip arthroscopy one of the most closely studied surgical techniques in orthopaedics, and have demonstrated that hip arthroscopy provides efficacy and clinically important benefit in specific indications. Although similar evidence is not yet available for pediatric and adolescent patients, the growing experience and opportunity in the area have led to incredible development in the field and further embrace of hip arthroscopy as a surgical tool and technique with important pediatric impact and even more so future potential.

  4. Predictors of True Scaphoid Fractures in Children


    This study is a retrospective cohort study of children presenting to a tertiary pediatric hospital with hand or wrist injuries. Patients were grouped based on the presence of a true scaphoid fractures (confirmed on imaging) or those with clinical suspicion of a scaphoid fracture alone (no radiographic evidence of fracture). Demographic and clinical characteristics were compared with univariate and multivariate statistics to identify fracture predictors.

  12. When Should Bisphosphonates Be Used in Children with Chronic Illness Osteoporosis?


    The decision to treat a child with a bisphosphonate hinges on distinguishing bone fragility from typical childhood fractures, and determining the potential for medication-unassisted recovery following an osteoporotic fragility fracture. While improvements in BMD are a well-known sign of recovery, restitution of bone structure is also a key indicator of recuperation, one that is unique to childhood, and that plays a pivotal role in the decision to intervene or not.

  13. Vitamin D supplementation for children with cancer: a systematic review and consensus recommendations


    Further research is needed; until then, we recommend dietary vitamin D/calcium intake in keeping with standard national guidelines, and periodic 25OHD monitoring to detect levels <20 ng/ml. Vitamin D/calcium supplementation is recommended in children with low levels, to maintain levels ≥20 ng/ml year-long.

  15. Advances in Bone Assessment Methods in Children


    INTRODUCTION Pediatric bone diseases present with a variety of signs and symptoms. Although some diagnoses may be straightforward based on history and physical examination, other presentations require more extensive bone assessments. In addition, clinical followup, research studies, and drug trials are predicated on strong bone health assessment.
