Relation entre la nivologie et la traumatologie en station de sports d’hiver, en Isère, Savoie et Haute-Savoie : étude prospective pendant l’hiver 2020 (étude NiTrau)

Abstract : Introduction: Every year, 140.000 injuries are related to snow sports. Many risk factors are known. Snow conditions also seem to play a role but remain poorly studied. The goal of this study is to assess the link between snow conditions and the occurrence of limbs’s injuries. Method: A prospective and multicentric observational epidemiological study, has been conducted in 4 mountainside medical centers in the Northern French Alps from February 1st to March 15 of the year 2020. Patients supported by snow patrol for trauma were included. Axial injuries, wounds and collisions were excluded from the analysis. The primary outcome was the comparison of the prevalence of limb injuries (upper or lower) as a function of snow conditions (soft or hard). Results: Datas from 724 patients were collected, 520 lesions from 471 patients (87.5% of skiers) were analyzed. We noted: 88 lesions (54%) of the upper limb on hard snow, 74 (46%) on soft snow, 123 lesions (34%) of the lower limb on hard snow, 235 (66%) on soft snow. Analysis of the primary outcome showed an increased risk of lower limb lesions on soft snow (OR=2.518; 95%IC: 1.621-3.910; p<0.001), compared to upper limb lesions, and a decreased risk of lesions of the upper limb on soft snow (OR=0.397; 95%IC: 0.256-0.617; p<0.001), compared to the lower limb lesions.Conclusion: This study shows that soft snow is a factor contributing to lesions of the lower limb and protects against lesions of the upper limb. The opposite association is found on hard snow. These results bring new elements to the pathophysiology of snow sports injuries and allow new preventive measures to be considered.
