Overloads resulting from the volume of movements in choreography and sports. Message IV. Pelvis and hip joints apophysitis (diachronic analysis)

Abstract

High-amplitude movements in ballet and sports significantly increase the load on the tendon-muscleligament apparatus of the pelvis and hip joints, which leads to apophysites. The aesthetic demands for movements requiring leg turnout significantly modifies the biomechanics of musculoskeletal motion, creating overuse in structures that are rarely "overused" during natural (without turning legs out) movements. Overuse injuries in these children and adolescents are much more common than acute injuries. Most apophysitis, especially apophysitis of pelvic bones and hip joints, remain undiagnosed and mixed up with usual sports injuries. The difficulty in diagnosing the apophysites is that almost all modern methods of instrumental diagnostics are not apophysitis specific and, in most cases, visualize a variety of age norm. Physical examination still remains the optimal method of apophysites diagnostics
