Rapid disintegration and weakening of ice shelves in North Greenland.

The glaciers of North Greenland are hosting enough ice to raise sea level by 2.1 m, and have long considered to be stable. This part of Greenland is buttressed by the last remaining ice shelves of the ice sheet.

Ultrasound Assessment of Ankle Syndesmotic Injuries in a Pediatric Population.

Objective: To determine sensitivity and specificity for anterior-inferior tibiofibular ligament (AiTFL) integrity and tibiofibular clear-space (TFCS) cut-off points for dynamic evaluation using ultrasound (US) in a pediatric population.

Design: Prospective cohort study.

Setting: Tertiary care university-affiliated pediatric hospital patients between the ages of 12 and 18 sustaining acute ankle trauma with syndesmotic injury.

Development and validation of a French-language cross-cultural adaptation of the Pedi-IKDC Questionnaire.

Background: The Pedi-IKDC is an English-language, knee-specific, paediatric questionnaire used by orthopaedic surgeons around the world as a valuable patient-reported outcome measure (PROM). The objective of this study was thus to extend the applicability of the Pedi-IKDC to French-speaking Canadian patients, for both clinical practice and research, by developing a French-language cross-cultural adaptation of the original version.

Hypothesis: The French adaptation of the Pedi-IKDC is valid and reliable for evaluating French-speaking children with knee conditions.

Are outdoor playgrounds the real culprit for elbow fractures in children? A lesson learned from COVID-19 sanitary measures.

Background: The association between elbow fractures and outdoor playgrounds has always been anecdotal. We sought to determine the impact of closing outdoor playgrounds and other play areas during the COVID-19 lockdown on elbow fractures in a pediatric population.

Methods: We conducted a retrospective cohort study of all elbow fractures from a single pediatric referral hospital between 2016 and 2020 for the months of April and May.

Parents can reliably and accurately detect trunk asymmetry using an inclinometer smartphone app.

Purpose: An inclinometer smartphone application has been developed to enable the measurement of the angle of trunk inclination (ATI) to detect trunk surface asymmetry. The objective was to determine the reliability and validity of the smartphone app in the hands of non-professionals.

Methods: Three non-professional observers and one expert surgeon measured maximum ATI twice in a study involving 69 patients seen in the spine clinics to rule out scoliosis or for regular follow-up (10-18 y.
