Myositis Ossificans Progressiva in the Whole Spine: A Case Report

Myositis ossificans progressiva is a rare inherited disease characterized by progressive ectopic ossifications associated with thumb and big toe anomalies. Ossification usually progresses from central to the peripheral, proximal to distal, cranial to caudal, and from dorsal to ventral directions and leading to activity limitation, significant eating disability, recurrent pulmonary infection, and atelectasis. In this report, we present a 7-year-old boy with a total spine stiffness (wooden spine) seriously limited his activity of daily living.
