Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
Mouth breathing can particularly affect the growing face, as the abnormal pull of these muscle groups on facial bones slowly deforms these bones, causing misalignment. The earlier in life these changes take place, the greater the alterations in facial growth, and ultimately an open mouth posture is created where the upper lip is raised and the ...
The overlying skin is freely movable, and contracture of the toes does not occur in the initial stages. [6] A plantar fibroma right below the 2nd toe. The typical appearance of plantar fibromatosis on magnetic resonance imaging (MRI) is a poorly defined, infiltrative mass in the aponeurosis next to the plantar muscles. [8]
Wasting atrophy of muscle tissue of the lower parts of the legs may give rise to a "stork leg" or "inverted champagne bottle" appearance. Weakness in the hands and forearms occurs in many people as the disease progresses. [10] High-arched feet or flat-arched feet are classically associated with the disorder. [11]
Muscle atrophy is the loss of skeletal muscle mass. It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Muscle atrophy leads to muscle weakness and causes disability.
Foot drop in one or both feet can occur. [14] Part of the cause for this dysfunction is the early involvement of the quadriceps muscles. [1] Weakness of the tibialis anterior muscle is responsible for foot drop. Another common early symptom is trouble manipulating the fingers, such as difficulty with tasks such as turning doorknobs or gripping ...
The most common cause of foot pain is wearing ill fitting shoes. Women often wear tight shoes that are narrow and constrictive, and thus are most prone to foot problems. Tight shoes often cause overcrowding of toes and result in a variety of structural defects. The next most common cause of foot disease is overuse or traumatic injuries. [3]
Prolonged mouth opening (hyper-extension) is also suggested as a possible cause. It is thought that this leads to microtrauma and subsequent muscular hyperactivity. This may occur during dental treatment, with oral intubation whilst under a general anesthetic , during singing or wind instrument practice (really these can be thought of as ...
