Femoroacetabular impingement of players of table tennis

Introduction: Question of femoroacetabular impingement is very actual. This young concept brings mechanism which leads to early degenerative changes of the hip joint of young and active individuals (athletes). Objectives: To review influence of sport activity on condition of the hip joint of young athletes (players of table tennis) and to determine incidence of femoroacetabular impingement and its clinical significance. Methods: We performed ultrasound and clinical examination and questionnaire with 22 individuals from 2 training groups. Groups vary in age, height, weight, volume of sport activity and how long they do sports. We found out incidence of cam-type impingement and evaluated pain of anterior impingement test, ranges of motions of the hip joint and deep squat. Results: Cam impingement was found in 27 hip joints, 16 in older group, 11 in younger one. In older group there were 12 from 16 impingements painful during anterior impingement test, 4 from 11 in younger one. In older group there were 4 symptomatic individuals, none in younger one. Older group has lower ranges of motion of flexion and internal rotation. 4 individuals did not perform deep squat, all of them with bilateral cam-type impingement. Conclusion: Femoracetabular impingement is frequent among young athletes. It causes..
