title: Longitudinal epiphyseal bracket.
abstract: 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. Previously, longitudinal epiphyseal bracket has been treated with angular osteotomy, but we recommend early surgical physiolysis. We describe this uncommon disorder, our current recommendation for treatment, and present three illustrative cases.
