Muscle contracture

Introduction Contracture is also called sputum, which means muscle spasm. Muscle contracture refers to the clinical syndrome of specific gait and signs manifested by fascial fibrosis and contracture of the muscles and muscles. Muscle contracture shows the positional malformation of the contracture site, severe pain around the joint, depression on the skin, and abduction and flexion limitation of the joints of the extremities. Here are two types of muscle contracture that can occur in children: Forearm muscle contracture: Muscle ischemic contracture usually begins quickly. After trauma, especially in children with supracondylar fractures, the limbs have persistent severe pain, the brachial artery pulsation is obviously weakened or disappeared, the fingers are flexed, and the pain is exacerbated when passively straightening. In addition, there is swelling, chills, cyanosis, sensation or loss of the distal end of the limb. In these symptoms, the disappearance of arterial pulsation and the passive extension of the finger cause severe pain are the main basis for diagnosis. Gluteal muscle contracture: This disease is often bilateral, rare on one side, and there are reports of more men than women.

Cause

1. Injectability: After repeated intramuscular injection, the fascial fibers of the muscles and muscles are degenerated and contracted to cause muscle contracture.

2, congenital muscle contracture.

3, central nervous system lesions, local inflammatory stimuli can also cause meat contracture.

4. Local compression such as cast gypsum, bandage over-tightening, vascular injury or replantation of the broken limb, muscle contracture caused by ischemia.

5, muscle ischemia, direct muscle injury, hematoma, infection, multiple myofascial contractures and so on.

6. Nerve damage to the part where the muscle is located.

Hip dysfunction

In the patient's hip, the internal rotation of the hip joint is limited, and the adduction activity is limited. When standing, the external extremity is rotated. It can't be high and completely close. Walking often has eight outer, swinging gait and quick step, sitting in a jumping state. When you are down, your legs can't go together, the hips are separated by frogs, and one side of the thighs is difficult to rest on the other side of the thighs (cross-leg test). When the squatting activity is light, the knees are separated first, then the squatting is followed by the squatting. The heavy one can only be frog-like.

2. Pelvic variant

Patients with long course of disease may have acetabular sulcus convex to the pelvic cavity, children with gluteal small muscle contracture have large trochanter epiphysis hypertrophy, bilateral asymmetrical gluteal muscle contracture children may have pelvic tilt and secondary lumbar scoliosis The severe lateral anterior superior iliac spine is lower on the lighter side, the heavy side umbilical hernia is longer than the light side, and the distance from the greater trochanter to the ankle is equal.

Differential diagnosis

Differential diagnosis of muscle contracture:

1. Deltoid muscle contracture: MRI can be found in the deltoid muscle with a typical fiber cord, starting from the upper surface of the shoulder and extending to the deltoid nodules.

2, forearm muscle contracture: muscle ischemic contracture usually begins quickly. After trauma, especially in children with supracondylar fractures, the limbs have persistent severe pain, the brachial artery pulsation is obviously weakened or disappeared, the fingers are flexed, and the pain is exacerbated when passively straightening. In addition, there is swelling, chills, cyanosis, sensation or loss of the distal end of the limb. In these symptoms, the disappearance of arterial pulsation and the passive extension of the finger cause severe pain are the main basis for diagnosis.
