Vertebral osteochondrosis
Introduction
Introduction to vertebral osteochondrosis Vertebral osteochondrosis (Calve disease), also known as the flat vertebrae, is a rare osteochondrosis. The disease is due to the sterile necrosis of the primary ossification center of the vertebral body, and then under the longitudinal pressure of the spine, the diseased vertebrae are flattened, and the bone is dense or even broken. There are two vertebrae, one is the primary callus, located in the middle of the vertebral body, has existed at birth, about 6 to 10 years old. The second is the iliac crest, which is located above and below the vertebral body and is connected to the intervertebral disc in a ring shape. Appeared at about 16 years old, and merged with the vertebral body around the age of 25. Both can cause ischemic necrosis and produce a series of pathological changes and clinical manifestations, but the causes of these two types of osteophytes have been widely debated and have not been publicly discussed. Repeated and concentrated chronic injury has an important role in the occurrence and development of vertebral osteochondrosis, with or without pre-position factors. basic knowledge Sickness ratio: 0.05% Susceptible people: no specific population Mode of infection: non-infectious complication:
Cause
Cause of vertebral osteochondrosis
The disease is due to the sterile necrosis of the primary ossification center of the vertebral body, and then under the longitudinal pressure of the spine, the diseased vertebrae are flattened, and the bone is dense or even broken.
Prevention
Vertebral osteochondrosis prevention
The disease is a self-healing disease with an active period of about 2 years. If there is a hunchback deformity, it is impossible to completely correct it. In adulthood, the treatment of early secondary osteoarthritis is to prevent deformity and protect the spine from oppressive damage until the tarsal plate matures. In the past, the use of long-term lying gypsum beds has been used sparingly. If the disease is obvious at the initial stage, it can be considered to be fixed in a plaster bed or a plaster vest for 2 to 3 months, and then the back muscles are used for the stent and exercise. If the child is painless, the treatment can be determined according to the deformity. When the posterior kyphosis is less than 45~50°, as long as the corrective gymnastics can be performed; at 50-80°, the stent should be fixed and the back muscle training should be used. There are very few patients with hunchback obvious, affecting the appearance, but need to do spinal orthopedics and fusion surgery, occasional spinal cord compression symptoms and need to decompression.
Complication
Vertebral osteochondrosis complications Complication
Juvenile vertebral osteochondrosis often occurs in adolescents with rapid growth. The main cause of most patients is kyphosis, some of whom may have back pain, and 50% complain that the pain is mainly in the deformed or lower back. After the activity is aggravated, it usually decreases with the end of growth. Only 25% of the patients after the maturity period have more typical symptoms. If the pain is located at the waist and the deformity is in the chest, the possibility of pedicle cracking should be considered.
Symptom
Vertebral osteochondrosis symptoms Common symptoms Thoracic vertebrae thoracic deformity Smooth muscle spasm
The disease occurs in children 2 to 10 years old, and the general complaint is pain in the thoracic vertebrae. Examination revealed a mild localized kyphosis of the spine. The affected vertebral body had deep tenderness and limited spinal motion, which may be associated with mild tendon.
Examine
Examination of vertebral osteochondrosis
1 occurs in the lower thoracic vertebra, a small number occurs in the lumbar vertebrae, often only involving a vertebral body.
2 The vertebral body is flat like a coin, and its anteroposterior diameter and transverse diameter are larger than the adjacent vertebral bodies, the bone is dense and the edges are smooth.
3 There is no change or slight widening of the adjacent intervertebral space.
4 pedicle and attachment are not invaded, no paravertebral abscess or soft tissue mass shadow.
5 The height and density of the vertebral body can be completely or partially restored after the lesion has healed.
Diagnosis
Diagnosis and differentiation of vertebral osteochondrosis
diagnosis
Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.
Differential diagnosis
The flat vertebra is an X-ray sign that can cause many causes of flat vertebrae. Should be identified with eosinophilic granuloma, spinal tuberculosis, suppurative spondylitis, tumors, especially metastatic cancer, and hyperparathyroidism, osteogenesis imperfecta.
