joint contracture
Introduction
Introduction Joint contracture is one of the clinical manifestations of congenital joint contracture. Congenital joint contracture refers to the flexion contracture state of the joint in the intrauterine position. At birth, the body is flexed or the joints are stiff, that is, congenital multiple joint contractures. Again, it can be ignored. Joint development begins at 2 months of gestation, and lesions with reduced uterine movement (uterine hypoplasia, multiple births, and oligohydramnios) can cause joint contracture. Congenital polyarticular contracture is caused by neurogenic, myopathy, and related tissue diseases.
Cause
Cause
Joint development begins at 2 months of gestation, and lesions with reduced uterine movement (uterine hypoplasia, multiple births, and oligohydramnios) can cause joint contracture. Congenital polyarticular contracture is caused by neurogenic, myopathy, and related tissue diseases. Congenital myopathy, anterior horn cell disease, and maternal weakness are thought to be the cause of muscle hypoplasia. Congenital polyarticular contracture is not a hereditary disease, but hereditary diseases (such as 18 trisomy, spinal sulcus) can increase the incidence of joint contracture.

1, with shoulder joint adduction, inward rotation, elbow joint overextension, wrist joint, interphalangeal joint flexion. The hip may be dislocated, usually with a slight hip flexion. Knee joints are overextended, often inversion, and internal retraction. The calf muscles are poorly developed and the limbs lack muscle appearance and are tubular. The joint is excessively flexed forward. Soft tissue wings can sometimes be presented. The spine may be bent sideways. Except for the long bones, the X-rays of other bones are normal. The movement disorder is very serious. Intelligence is not affected or mildly abnormal.
2, congenital multiple joint contracture often accompanied by other malformations including microcephaly, cleft palate, cryptorchidism, urinary tract malformation.
3. A comprehensive assessment of all malformations associated with the disease is required prior to diagnosis. Electromyography and muscle biopsy are helpful in the diagnosis of neurological or muscular disorders. Muscle biopsy is often characterized by muscle fiber dysplasia, accompanied by proliferation of fibrous and adipose tissue, replacing normal muscle fibers.
4. The malformation of the disease is the most common at birth, and will not continue to develop in the future. Many children perform well, and 2/3 of them can walk freely without bed.

Differential diagnosis
Congenital multiple joint contracture: congenital multiple joint contracture is caused by muscle, joint capsule and ligament fibrosis, resulting in a syndrome characterized by multiple joint stiffness throughout the body.
