“…28,29 The 10 m/s impact velocity simulates a patient involved in a bicycle collision, accident or fall. 30 In this study, a 100N functional biting load was simulated for comparison with the 10 m/s impact model. This anterior bite force was based on values from two studies which were found to vary between 59.5 and 155 N. 14,31 When the bite load was applied on the palatal surfaces of the incisors, the stresses around the adjacent teeth were about 75% lower than during the impact.…”

Background/Aims Dental trauma is the cause of several consequences to the injured tooth. However, the stresses and strains at adjacent teeth non‐directly impacted as a possible cause of sequelae are still unknown. The aim of this study was to evaluate the stress distribution in incisors adjacent to an upper central incisor when it suffers a frontal impact in order to identify a potential explanation for sequelae in non‐traumatized teeth. Materials and Methods A three‐dimensional (3D) finite element model of the maxillary central incisors, lateral incisors and canines was created from a cone‐beam scan of a patient with normal occlusion. Non‐linear dynamic impact analysis was performed, simulating the right central incisor being impacted by a steel ball with a velocity of 10 m/s. A functional chewing load (100 N) on the palatal surface of the central incisor was simulated for comparison. Displacements, strains and modified von Mises stresses were calculated for the adjacent teeth. Results During impact on the central incisor, the adjacent teeth showed root displacement. Considerable stress concentrations were observed on the palatal surfaces, proximal and labial surfaces of teeth adjacent to the traumatized incisor. Stresses in the adjacent teeth were higher than stresses calculated during functional biting. Compressive stresses were concentrated at the proximal areas of the adjacent incisors. High levels of deformation were found in the root dentin of adjacent teeth during the traumatic event. Conclusions A frontal impact on an anterior tooth generated stresses at the roots of adjacent teeth. These stresses may play a role in clinically observed sequelae of teeth adjacent to traumatized teeth.

“…[34][35][36][37] Previous studies reveal a discrepancy between bikers acknowledging the importance of helmet use versus actually choosing to wear helmets, which indicates that helmet advocacy initiatives might improve rates of helmet use. 38,39 In conjunction with interventions such as improving bike lanes and educating motorists, helmet advocacy may help to reduce the incidence of cycling-related TSIs.…”

OBJECTIVE Sports injuries are known to present a high risk of spinal trauma. The authors hypothesized that different sports predispose participants to different injuries and injury severities. METHODS The authors conducted a retrospective cohort analysis of adult patients who experienced a sports-related traumatic spinal injury (TSI), including spinal fractures and spinal cord injuries (SCIs), encoded within the National Trauma Data Bank from 2011 through 2014. Multiple imputation was used for missing data, and multivariable linear and logistic regression models were estimated. RESULTS The authors included 12,031 cases of TSI, which represented 15% of all sports-related trauma. The majority of patients with TSI were male (82%), and the median age was 48 years (interquartile range 32–57 years). The most frequent mechanisms of injury in this database were cycling injuries (81%), skiing and snowboarding accidents (12%), aquatic sports injuries (3%), and contact sports (3%). Spinal surgery was required during initial hospitalization for 9.1% of patients with TSI. Compared to non-TSI sports-related trauma, TSIs were associated with an average 2.3-day increase in length of stay (95% CI 2.1–2.4; p < 0.001) and discharge to or with rehabilitative services (adjusted OR 2.6, 95% CI 2.4–2.7; p < 0.001). Among sports injuries, TSIs were the cause of discharge to or with rehabilitative services in 32% of cases. SCI was present in 15% of cases with TSI. Within sports-related TSIs, the rate of SCI was 13% for cycling injuries compared to 41% and 49% for contact sports and aquatic sports injuries, respectively. Patients experiencing SCI had a longer length of stay (7.0 days longer; 95% CI 6.7–7.3) and a higher likelihood of adverse discharge disposition (adjusted OR 9.69, 95% CI 8.72–10.77) compared to patients with TSI but without SCI. CONCLUSIONS Of patients with sports-related trauma discharged to rehabilitation, one-third had TSIs. Cycling injuries were the most common cause, suggesting that policies to make cycling safer may reduce TSI.

“…Everyone must use protective equipment when riding a bicycle to minimize this risk of death and injury. 7 Since bicycle helmet, which is a protective equipment, significantly reduces face, nose fractures and fractures around eye and brain injuries, its use need to be promoted and popularized. [7][8][9] Despite such protection provided by helmets, most bicyclists do not wear helmets at all.…”
