| Popis: | Flaring of the ischiopubic synchondrosis at the time of fusion is a common clinical observation in pediatrics and represents a normal physiological process in skeletal maturation. When presenting unilaterally, this flaring can mimic a range of serious pathological conditions such as osteomyelitis, osteal tumors, and traumatic injury. An improved understanding of ischiopubic synchondrosis fusion is therefore critical to avoid potential misdiagnosis. Retrospective multi-slice computed tomography pelvic scans of Australian individuals aged neonate to 24 years (n = 184) were assessed using a novel five stage morphological classification system of the maturation and fusion of the ischiopubic synchondrosis. Maturation scoring was conducted using both multiplanar formatting views and volume-rendered reconstructions in OsiriX™. Maturational stage was strongly related to age (P 0.001) with fusion of the ischiopubic synchondrosis observed between the ages of 4 and 9 years in females and 7 and 13 years for males. The highest probability of fusion in our Queensland Australian population based on multinomial regression predictive modeling was between 7 and 10 years of age. We documented three variants of fusion: pubic and ischial outgrowths, appearance of a secondary ossification center, and a fusiform-shaped enlargement. This study provides the first predictive modeling of the timing of fusion of the ischiopubic synchondrosis using a reliable morphological classification system. The significant variation in timing and progression of fusion of the ischiopubic synchondrosis reported in this study, will aid in minimizing misdiagnosis and unnecessary treatment in children presenting with asymmetrical or delayed ischiopubic synchondrosis anomalies.
