Abstract

Avulsion fractures occur when tendons or ligaments are subjected to forces greater than they can withstand at the apophysis or enthesis, regardless of the fusion status. Given the diverse muscular structures around the pelvis and hip joint, which serve as origins for multiple muscles leading to the lower extremities, these areas are vulnerable to such injuries. Pelvic avulsion fractures commonly af-fect young athletes, but they can also occur in adults. Diagnosis typically involves assessing the trauma history, clinical examination, and radiographic imaging. In cases of unclear diagnosis, additional tests, such as computed tomography or magnetic resonance imaging, may assist in treatment decisions and diagnosis. Although most avulsion fractures respond well to conservative treatment, surgical interven-tion may be preferred in severe displacements, significant retraction in active athletes, or when a faster recovery is necessary. Chronic or neglected injuries may lead to excessive osseous formation around the pelvis, causing impingement syndromes. Recognizing the characteristic radiological findings based on the pelvic anatomy aids in accurate diagnosis because chronic injuries might mimic tumors or infectious conditions, necessitating a careful differential diagnosis.
