Pelvic apophyses are places of insertion of strong muscles and tendons and are therefore places of least resistance at the end of skeletal growth. Avulsions and disruptions of pelvic apophyses can be caused by overstrain during different kinds of sport activity. Typical radiological findings in 8 different cases of ruptures of apophyses, osteochondropathies, and resulting conditions of sport injuries are demonstrated. The difficulties of correct diagnosis and differential diagnosis are pointed out. The significance of hormonal impairment of ossification for development and stress factor of pelvic apophyses is exposed. Questions of treatment and follow-up studies are discussed.

Purpose: This study presents a rare case of avulsion fracture of the anterior inferior iliac spine, typically occurring in adolescents engaged in physical activities. The purpose of this study is to emphasize the diagnostic challenges and conservative treatment options available for this condition.
Method: We describe the case of a 14-year-old healthy adolescent who suffered from an avulsion fracture following pelvic trauma after participating in a short-distance sprint.

The development of the pelvis follows a predictable pattern of ossification that involves the maturation of bone, synchondroses, and apophyses. These growth centers appear and close at distinct times during skeletal maturity and give rise to structural changes in the pelvis that can be distinctively appreciated on various imaging modalities. Accurate interpretation of radiologic images requires knowledge of skeletal development because the varying appearance of the maturing pediatric pelvis may be mistaken for pathology.

Introduction: Pelvic apophyseal avulsion fractures are uncommon injuries that frequently affect adolescents while participating in sports. This occurs because the enthesis cannot withstand the tractional force applied because the apophysis has not yet fully fused. Due to its complex muscular structure, being the origin of several muscles that cross two lower extremity joints, the pelvis has an increased risk for such injuries.

Soccer is the most popular sport worldwide, and it is associated with high injury rates, with most of these injuries occurring in the lower extremities. Particularly, in youth soccer players with immature skeleton, the physeal plate is two to five times weaker than the surrounding fibrous structures, and therefore more vulnerable to injury. The physeal plate consists of epiphyses and apophyses, with the former serving as tendon attachment sites and being subject to traction forces.

Purpose Of Review: The pelvis and hip account for 0.3--4% of fractures of the immature skeleton, and generally result from high energy trauma. These fractures range in severity from apophyseal avulsions to complete disruptions of the pelvic ring.
