Congenital Elbow Fusion
Introduction
Introduction to congenital elbow fusion Congenital elbow fusion is rare and can occur alone or in combination with other malformations, such as lack of ulna, fusion or absence of carpal, metacarpal or phalanx. When it exists independently, it often involves bilateral elbow joints. The incidence is not related to gender. The common symptoms of this disease are abnormal body types. basic knowledge The proportion of illness: 0.002% Susceptible people: young children Mode of infection: non-infectious Complications: muscle atrophy
Cause
Congenital elbow fusion cause
The disease is a rare congenital disease, and its pathogenesis is still unclear. It is generally believed that the embryo is in the fifth week of development, and the mesoderm cartilage branch leaves the trunk and matures. During the process of forming the ulna and ulna, the proximal end is not separated. .
Prevention
Congenital elbow fusion prevention
The disease is congenital disease, no effective preventive measures, early diagnosis and early treatment is the key to the prevention and treatment of this disease, but it should be noted that for children, the surgical treatment time should not be delayed too late to prevent hand muscle disuse Shrinking.
Complication
Congenital elbow fusion complications Complications muscle atrophy
The disease can occur alone or in combination with other diseases, such as lack of ulna, carpal, metacarpal or phalanx fusion or absent.
In some non-simple bone fusion malformations, in addition to skeletal malformations, fascial tissue contracture, abnormal fiber direction, interosseous stenosis, abnormal or abscess in the supinator muscle.
Symptom
Congenital elbow fusion symptoms common symptoms muscle atrophy forearm pronation
The patients mainly showed different degrees of pronation deformity, and the bilateral forearm activity was limited. If the time is long, it may lead to muscle atrophy.
Examine
Congenital elbow fusion
The main cause of this disease is X-ray examination.
Joint stiffness can occur in sputum, squat or ulnar joints, such as the occurrence of ulnar or ankle joint fusion, often lack of humerus or ulna.
In infants and young children, joint fusion may be cartilage, which cannot be shown on X-ray films. With the appearance of growth and internalization, elbow fusion can be shown on X-ray films, and the degree of elbow function loss and elbow fusion Fixed position, dysplasia or lack of shoulder joint or humeral head can aggravate deformity and shoulder instability.
Diagnosis
Diagnosis and diagnosis of congenital elbow fusion
According to its clinical manifestations and X-ray examination results, the diagnosis is easier, but sometimes it needs to be differentiated from the elbow joint fusion surgery. Because of its similar clinical manifestations, the latter has a history of surgery and can be identified.
