We describe a fractureseparation of the epiphyseal plate of the distal tibia (Salter-Harris type III, or juvenile fracture of Tillaux) in a 15-year-old girl. The case is of interest, above all, in that the trauma occurred during the execution of a yoga posture. The literature does not speak of complications or traumatic consequences of this type of activity. Analyzing the biomechanics of the traumatic event, it appears that even a physical exercise characterized by slow and gradual movements can cause severe damage, such as the injury described.
