Youth Sexual Hunchback

Youth Humpback Introduction The disease is caused by the imbalance of the load capacity of the spine and the load it bears. It is also known as "juvenile kyphosis" and Scheuermann disease or disease. The lesion mainly involves the middle and lower thoracic vertebral bodies. The lesion occurs in the second ossification center of the vertebral body, ie the tarsal plate above and below the vertebral body. For various reasons, the blood supply to the tarsal plate is reduced, the cartilage plate is thinned, the pressure is reduced, and the rupture occurs under excessive load. The nucleus pulposus protrudes into the vertebral body at the rupture, forming a so-called Schmorl nodule, the thoracic thoracic segment. Bending backwards, the pressure on the front of the vertebral body is greater than the rear, and the necrosis of the anterior epiphysis affects the development of the height of the anterior vertebral body. Through the passive activities of the doctor, the hunchback can be corrected as the active hunchback. Can not be corrected for fixed kyphosis, such as ankylosing spondylitis. In 1920, the Danish physician Scheuermann first identified its radiological features and distinguished it from other spinal deformities as an independent disease. According to the literature, the incidence of Hume disease in the general population can be as high as 8.0%. The disease occurs in 13 to 17 years old. It is found in manual labor with premature load. Male patients are 4 to 5 times more likely than female patients; 25% have a family history. basic knowledge The proportion of illness: 8.0% Susceptible people: teenagers Mode of infection: non-infectious Complications: osteoarthritis

Youth hunchback cause

Blood supply disorder (25%):

The blood supply disorder reduces the blood supply to the tarsal plate and reduces the biological strength of the tarsal plate; the lesion occurs in the second ossification center of the vertebral body, ie on the vertebral body, the lower tarsal plate, for various reasons, the sacral blood The supply is reduced, the cartilage plate is thinned, the anti-stress is reduced, and the fragmentation occurs under excessive load, and the nucleus pulposus protrudes into the vertebral body at the rupture to form a so-called Schmorl nodule.

Premature degeneration of the intervertebral disc (20%):

With the increase of age, the nucleus pulposus gradually degenerates, the water loses, the elasticity decreases, the premature degeneration of the intervertebral disc reduces its buffering effect, and causes uneven stress on the vertebral body surface. In adolescence, the development is not complete, the vertebra Excessive force in front of the body makes the vertebral body wedge-shaped. In addition, some factors increase the load on the vertebral body, such as excessive weight gain; excessive weight-bearing labor; multiple minor trauma; bilateral achilles tendon shortening. The load on the thoracic plate of the thoracolumbar section is increased when the person bends, causing damage to the cartilage.

External stress factors (35%):

For various reasons, the blood supply to the tarsal plate is reduced, the cartilage plate is thinned, the pressure is reduced, and the rupture occurs under excessive load. The nucleus pulposus protrudes into the vertebral body at the rupture, forming a so-called Schmorl nodule, the thoracic thoracic segment. Bending backwards, so that the pressure in front of the vertebral body is greater than the rear, the necrosis of the anterior epiphysis affects the development of the height of the anterior vertebral body. With the increase of age and the growth of the body, the height of the posterior vertebral body is more and more than the height of the first half. The vertebral body is wedge-shaped, and a plurality of wedge-shaped vertebral bodies enlarge the kyphosis of the thoracic vertebrae to form a hunchback.

Youth humpback prevention

The patient should be placed in a hard bed. When standing and sitting, try to stretch the chest and back, keep a good posture, avoid excessive bending or weight-bearing activities, and strengthen the back muscle exercise. I hope to strengthen the back muscle strength and limit the kyphosis. Aggravated.

Youth humpback complications Complications osteoarthritis

It can be complicated by the lordosis of the lumbar, the kyphosis of the thoracic vertebrae, and the osteoarthritis of the spine in the late stage.

Youth hunchback symptoms common symptoms severe pain hunchback back pain

Early symptoms include back pain and discomfort, relatively obvious hard feeling, pain is located in the midline of the spine, relatively mild, rarely severe pain, discomfort after exertion, rest can be relieved, after the chest kyphosis gradually enlarges, difficulty straightening, During the examination, the back can be found to have an arc-shaped posterior bulge. Passive and active activities can not change the kyphosis. The lordosis of the waist is increased, but the activity of the waist is normal. At the end of the disease, the symptoms disappear and the back of the thoracic vertebrae The convex deformity is always present, and the osteoarthritis of the spine changes in the late stage.

Youth humpback examination

X-ray performance: The typical X-ray performance can be divided into three stages. The early vertebral body becomes wedge-shaped, the front is low and the height is high, and the upper and lower ankle rings are spotted. The upper and lower edges of the vertebral body are rough and the intervertebral space is slightly narrow. In the mid-term, the epiphysis broke, and the normal shape of the upper and lower corners of the vertebral body disappeared. Later, the epiphysis returned to normal density, but the vertebral body showed permanent wedge deformation.

In some cases, Schmorl nodules appear. On the X-ray film, there is an incision in the vertebral body. The vascular groove in front of the vertebral body is also one of the X-ray signs of the disease.

Juvenile hunchback diagnosis

diagnosis

Diagnosis can be made based on the patient's age, gender, early weight history and X-ray findings.

Differential diagnosis

However, it needs to be identified with the following diseases.

Active humpback

The hunchback can be corrected by the passive activity of the doctor or the active activity of the patient, such as posture hunchback, which is more common in adolescents due to poor posture; paralytic hunchback, hunchback due to weakness of the trunk muscle due to certain diseases; compensatory hunchback It is often secondary to excessive lordosis of the lumbar spine. These hunchbacks are characterized by a softer back, which can correct deformities through movement and X-ray without bone defects.

2. Fixed humpback

Some diseases can be secondary to fixed kyphosis, such as ankylosing spondylitis. The biggest difference between it and Scheuermann's disease is that the rigidity and deformity are not only in the thoracic vertebra but also in the entire spine, accompanied by changes in laboratory examination, spinal tuberculosis and spinal fractures. It can also cause hunchbacks, which are characterized by an angle of the back kyphosis, rather than a rounded deformity that is well-proportioned by Scheuermann's disease. X-ray examination can be used as a definitive diagnosis.
