Congenital scoliosis is an abnormal development of the vertebrae resulting in combination of partial formation, lack of separation or missing portion of the vertebra. The exact aetiology of congenital scoliosis remains unclear. It is influenced by genetic predisposition and environmental factors. We report a case series of congenital scoliosis with dysmorphic features in four siblings and discuss the description of spondylocostal dysostosis syndrome associated with congenital scoliosis. The dysmorphic features include hypertelorism, bilateral ptosis, high arch palate and webbed neck. Posterior spinal instrumentation and fusion surgery was performed in three siblings. All patients did well post-operatively with no neurological complications. Subsequent follow-up at one and two years after the operation showed that the curves remained unchanged and the fusions were solid.
