Bone defect in children

Introduction Bone defects mainly include two major parts: bone defect and defect repair. This is because the humerus is located under the skin, the fracture block is easy to separate when an open fracture occurs, and the probability of bone defect in the open fracture of the upper limb and the spine is small. Bone defect fractures occurred in 68% of the tibia, 22% of the femur, and about 10% of other parts. Bone defect is a common clinical disease and one of the problems in orthopedic treatment. At present, methods for treating bone defects include autologous bone and allogeneic bone transplantation, tissue engineering techniques and gene therapy, growth factors, and adjuvant therapy of physical therapy.

Cause

(1) Congenital factors

Cleft lip and palate is one of the common factors. According to statistics, the incidence of cleft lip and palate in China is 1. There are congenital ear injuries, of which ear defects are more common and nasal defects are less common. The above-mentioned defect malformation is mainly caused by maternal nutritional deficiency, endocrine disorders, infection, mental stimulation, injury and heredity during pregnancy.

(2) acquired factors

Trauma: Commonly damaged by jaws, ears, nose, eyes and limbs caused by work injuries, burns, blast injuries and traffic accidents.

Disease: The most common is the bone defect caused by surgical resection of various tumors.

Diagnosis can be performed based on clinical performance and laboratory tests.

Differential diagnosis

Osteoporosis (osteoporosis) is a systemic bone disease characterized by decreased bone mass and microstructural destruction of the bone, manifested by increased fragility of the bone, and thus the risk of fracture is greatly increased, even for minor trauma or Fractures are also prone to occur without trauma. Osteoporosis is a chronic disease caused by multiple factors. There is usually no special clinical manifestation before the fracture occurs. More women than men, common in postmenopausal women and the elderly. With the increase of the elderly population in China, the incidence of osteoporosis is on the rise, and it is a health issue worthy of attention in China and the world.

1. Local manifestations of skull defects: local pain, pain at the edge of the defect, unbearable brain pulsation, scalp plunging into the skull when the defect is high, and scalp even merging part of the brain tissue and ventricle when the defect is low .

2. Skull Defect Syndrome: mainly manifested as headache, dizziness, the patient's fear of pulsation, bulging, and collapse of the defect area, fear of sun exposure, fear of vibration, or even noise, often have poor self-control and difficulty in concentration. And memory decline, or depression, fatigue, ignorance and low self-esteem.

3. Long-term skull defect: When there is brain swelling or protrusion, the brain tissue can be atrophied and cystic. Children's skull defects become larger with the development of brain tissue, affecting normal brain development and low intelligence.
