IMPRESSION FRACTURE OF THE TIBIAL CONDYLES – TIPICAL CARVING SKIINJURY
Abstract
BACKGROUND Depression fractures of the tibial condyles due to sudden turn of one ski are more frequentski injury than it used to be. There seems to be a correlation between this injury andcarving skies. METHODS All depression fractures of the tibial condyles due to skiing injuries during 2004 and 2005,have been analysed with regard to mechanism of injury and fracture type. To explain themechanism of injury due to sudden turn of ski with carved edges, mathematical model wasused. RESULTS 48 patients were treated for fracture of the proximal tibia. 18 of these were depressionfractures of a tibial condyle, 13 lateral and 5 medial. All skiers skied on skies with carvededges. Mechanism of injury was in all cases of fracture of the medial condyle sudden turnof the ski inwards and in lateral condyle, outwards.Mathematical model of the influence of carving on the knee injury type has shown thatforce transmitted to lower limb is dependant on velocity and on the radius of the curvatureat ski turn, and this is determined by the radius of the curvature of the edge of the ski. Thisforce can be multiplied by additional decrease of the radius due to instant additionalbowing of skies, for instance when running into a sharp depression. CONCLUSIONS In this paper we present typical mechanism of the fracture of the tibial condyle, due tosudden turn of the ski with carved edges. Mathematical model explains how the force transmitted to the knee multiplies due to sudden decrease of the carved turn radius, or due tosudden additional bowing of skiesDownloads
