Stone Man Disease

(redirected from Generalized Myositis Ossificans)
A rare idiopathic or autosomal dominant MIM 135100 condition of irregular penetration and pre-pubertal onset, in which connective/interstitial tissues undergo extensive fibrosis and heterotopic ossification of ligaments, tendons, muscle, fascia, aponeuroses and skin, first seen in late childhood as firm masses. The abnormal development of bone may lead to stiffness in affected areas and may also limit movement in affected joints, e.g., knees, wrists, shoulders, spine, and/or neck
