Introduction: Pelvic apophyseal avulsion can limit young athletes' performance for months and may result in permanent disability. Nonoperative treatment is most commonly preferred, while surgical management with reduction and fixation is reserved for selected cases. Our aim was to evaluate outcomes of operative management of pelvic apophyseal avulsions in a series of adolescents and young adult athletes.
Materials And Methods: Operative room registries and medical records were reviewed to identify patients who received surgical treatment for pelvic apophyseal avulsions who were younger than 24 years and with a minimum of 12 month follow-up.
Results: Thirty-two patients (16.8 years ± 2.6) were identified. The most common avulsion sites were anterior inferior iliac spine (34.4%, N = 11) and ischial tuberosity (34.4%, N = 11). Other avulsions were five cases (15.6%) of the pubic apophysis, four cases (12.5%) of the anterior superior iliac spine apophysis and one case of the iliac crest apophysis. Seventeen cases (53.1%) underwent surgery early, i.e., during the first 3 months after the acute injury. Twenty-two cases (68.8%) involved reduction with internal fixation, and six cases (18.8%) involved resection of the fragment. Twenty-six athletes (81.3%, N = 26) reported good outcomes and were able to return to preinjury sports level. Six patients (18.8%) had moderate outcome and reported activity limitations during high-level sports. Large displacement (> 20 mm) or delayed (> 3 months) surgery was not associated with inferior outcomes (P = 0.690 and P = 0.392, respectively). Injury side (P = 0.61) or gender (P = 0.345) did not affect outcomes.
Conclusions: Operative management of pelvic apophyseal avulsion results in return to the preinjury sports level in more than 80% of the cases. However, while both acute surgery for large displacement and delayed intervention for failed nonoperative treatment are generally successful in improving sports function in these cases, comparative studies are required to refine criteria for surgery.

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.
