Perceptions of readiness for independent practice among graduating orthopedic surgery residents in Ontario in the last 30 years.

Background: There is increasing concern regarding the lack of physicians and underresourcing of the medical system in Canada. The training of orthopedic surgeons has emerged as an area of particular concern. The purpose of this study was to gain insight into the outcomes of graduates of orthopedic surgery residency programs in Ontario in the last 30 years.

Delayed fixation of distal radial fractures beyond three weeks after initial failed closed reduction increases the odds of reoperation.

Aims: We aimed to compare reoperations following distal radial fractures (DRFs) managed with early fixation versus delayed fixation following initial closed reduction (CR).

Methods: We used administrative databases in Ontario, Canada, to identify DRF patients aged 18 years or older from 2003 to 2016. We used procedural and fee codes within 30 days to determine which patients underwent early fixation (≤ seven days) or delayed fixation following CR.

Biomechanical design of a new proximal humerus fracture plate using alternative materials.

Comminuted proximal humerus fractures are often repaired by metal plates, but potentially still experience bone refracture, bone "stress shielding," screw perforation, delayed healing, and so forth. This "proof of principle" investigation is the initial step towards the design of a new plate using alternative materials to address some of these problems. Finite element modeling was used to create design graphs for bone stress, plate stress, screw stress, and interfragmentary motion via three different fixations (no, 1, or 2 "kickstand" [KS] screws across the fracture) using a wide range of plate elastic moduli (E = 5-200 GPa).

Material Properties and Engineering Performance of Bone Fracture Plates Made from Plant Fiber Reinforced Composites: A Review.

Bone fracture plates are usually made from titanium alloy or stainless steel, which are much stiffer than bone. However, overly stiff plates can restrict axial interfragmentary motion at the fracture leading to delayed callus formation and healing, as well as causing bone "stress shielding" under the plate leading to bone atrophy, bone resorption, and plate loosening. Consequently, there have been many prior efforts to develop nonmetallic bone fracture plates with customized material properties using synthetic fibers (e.

Rehabilitation after musculoskeletal injury: an overview of systems in the United States and Canada.

As North America is largely industrialized with a variety of available private transportation options, trauma is a common occurrence, resulting in significant burdens of disability and costs to the health care system. To meet increasing trauma care needs, there is a robust organization of trauma and rehabilitation systems, particularly within the United States and Canada. The American and Canadian health care systems share multiple similarities, including well-equipped Level I trauma centers, specialized inpatient rehabilitation units for polytrauma patients, and thorough evaluations for recovery and post-discharge placement.
