What is bone strain and what are the specific causes

Another type of bone strain is osteochondritis, which mostly occurs between the ages of 5 and 15, and the most common sites are the femoral head, ischial tuberosity, tibial tuberosity, calcaneal tuberosity, second metatarsal head, episcaphoid bone, humeral small head, distal radius, lunate, etc.

Fatigue periostitis and fractures are mostly caused by stretching, bruising, fatigue and tension in the periosteal area where the muscle is attached. It often relaxes or separates the periosteal tissue, and the periosteal is congested, edema, vasodilated, and subperiosteal hemorrhage. Further development of fatigue periostitis can cause fatigue fractures, poor blood circulation in the cortex, and fracture nonunion after injury.

Osteochondritis is mostly due to local overloading and chronic injury that impairs the anterior epiphyseal blood vessels, resulting in cell degeneration and necrosis and poor epiphyseal growth.

Clinical manifestations] pain, swelling, tenderness, periosteal hyperplasia, fracture line. In severe cases of osteochondritis, joint strangulation, disuse atrophy of muscle disuse, etc.

Routine**] Stop or change training, elastic bandage bandage, fixation, elevation of limbs, avoid weight-bearing, physiotherapy, massage of traditional Chinese medicine, local closure of hormones, surgery**.

Hyperbaric oxygen**] The first stage is 2 3 courses, and the second stage is about 2 courses after rest.

In the application of hyperbaric oxygen in sports medicine, the following issues should be noted:

1. It is necessary to follow the indications and contraindications of hyperbaric oxygen to prevent the occurrence of development syndrome and hyperbaric oxygen.

2. To integrate with various **integrations** that are unique to clinical and sports medicine.

3. Adjust the hyperbaric oxygen regimen in a timely manner according to the recovery and general condition.

4. Focus on prevention and health care.

Traditional Chinese medicine believes that the causes of osteoarthropathy are as follows:

1. Liver and kidney loss: Traditional Chinese medicine believes that the kidney stores essence and main bones; The liver hides blood and the main tendons. If the kidney essence is sufficient and the liver blood is full, the muscles and bones are strong and the joints are flexible.

When people reach middle and old age, physiological function declines, and the liver and kidney are deficient in sperm and blood, resulting in musculoskeletal dystrophy, and over time, osteoarthropathy is prone to occur.

2. Feeling external evils: weak internal organs, unstable external health, wind, cold, and dampness take advantage of the deficiency to invade, affecting the flow of qi and blood, and the meridian qi is not smooth, which is also a common cause of osteoarthropathy.

3. Chronic strain: often engaged in work such as bowing the head, bending over, standing for a long time, etc., resulting in unfavorable operation of qi and blood, tendons and veins, blood stasis block, resulting in muscles, muscles and veins bone dystrophy, local damage, resulting in pain, unfavorable joint flexion and extension, activity disorders and other clinical manifestations.

4. Falls: Due to violent trauma or excessive force on the affected part, the muscles and veins are damaged, resulting in poor flow of qi and blood, stagnation and obstruction, and osteoarthropathy occurs.

5. Congenital deformity: some patients have bone and joint deformities, although they are young and strong and asymptomatic, but after middle age, due to weak constitution, fatigue or feeling external evils, the deformed parts are prone to lesions.

In addition, the onset of the disease may also be related to genetics, constitution, metabolism and other factors.

The ** of strain injury is a chronic mechanical injury caused by overload, which is different from chronic or acute mechanical injury caused by external force such as sprain and contusion. However, if the area that is prone to strain is affected by acute or chronic trauma and is not completely injured, the affected area is more likely to be strained due to overload than the uninjured person. If there are senile changes such as bone spurs in the affected area, or if the muscle strength of the affected area is weakened due to general weakness, these can make the general stress exceed the tolerance capacity in a specific situation, and become overused injury resistance.

Therefore, acute and chronic trauma, bone spur formation, general weakness, and long-term bed rest often constitute the pre-inducements of strain.
