description: "Longitudinal epiphyseal bracket or bracket epiphysis is an uncommon disorder of growth. Alternatively known as a delta phalanx, it is due to an anomalous secondary ossification center that extends longitudinally along the diaphysis. Although rare, longitudinal epiphyseal bracket most commonly manifests in the hands as clinodactyly and in the feet as hallux varus."
