We report a patient who experienced no function problems during the 5-year follow-up after a conservative treatment for minimally displaced acetabular fracture that developed as a result of the formation of physeal bar. According to the computed tomography, triradiate cartilage was fractured and minimally displaced, which was identified as a Salter Harris type II physeal injury. A fracture of the anterior wall of the acetabulum was also observed. It was judged as a stable fracture, and conservative treatment was performed. On the follow-up x-ray, the physeal bar was formed in the damaged triradiate cartilage. At 5-year follow-up, physeal injury of the triradiate cartilage has influenced the acetabular growth, resulting in acetabular dysplasia, pelvic asymmetry, hypoplasia of pubis, and widening of the tear drop. However, anteversion and inclination of the injured acetabulum were similar with those of the contralateral side. Our patient also did not complain of any hip discomfort.
