Triple Innominate Osteotomy for Early Closure of the Triradiate Cartilage after Hip Joint Injury: A Pediatric Case Report

Acetabular fractures are less common in children than those in adults. Even these fractures are rarely seen in infants and usually such fractures require high-impact trauma. Orthopedic surgeons often recommend conservative treatment for acetabular fractures to accommodate remodeling features. In addition, pelvic osteotomies have demonstrated good results; specifically, triple innominate osteotomy treatment has been proven effective. In this study, we report the case of an 8 year-old girl who suffered from hobbling because of preclosure of triradiate cartilage and hip subluxation with left femoral diaphysis fracture resulting in malunion and lower extremity shortening. First we applied osteotomy and plate and screw osteosynthesis for femoral malunion and afterwards triple innominate osteotomy for subluxation caused by acetabular traumatic dysplasia and preclosure of triradiate cartilage. The results were quite satisfying in this case.
