1, car accident injury, leg infection, tissue necrosis. It is necessary to have a minor amputation. Minor amputation refers to the simultaneous removal of infected and necrotic tissues, open local amputation and limited resection of some tissues through partial vascular reconstruction or limb correction.

2. The leg was injured in a car accident because it could not be relieved by vascular reconstruction, drug control or minor amputation. Large amputation is divided into low amputation and high amputation. Low amputation is generally from below the knee 10 cm, while high amputation requires amputation from the thigh root.

After high amputation, the mortality rate of patients is more than 50% in two years and more than 80% in five years. The above survival rates are all amputation survival rates of osteosarcoma and bone cancer.

Second, the definition and standard of amputation

1. amputation: the end of a limb is cut off.

2. First amputation: the first amputation in a series of processes until the final result (recovery or death).

3. Repeated amputation: After the previous amputation was not cured, the amputation was started from the distal end again.

3. Bilateral amputation: amputation of both lower limbs at the same time, regardless of the degree of amputation.

4. Minor amputation: horizontal joint amputation at and below the ankle joint.

5. Major amputation: amputation above ankle joint.

Extended data:

Rehabilitation treatment includes two aspects: the general situation of the patient and the residual limb itself. It is difficult for amputees to master prosthetic limbs freely after long and arduous training.

1. Training before using artificial limbs

Exercise training increases physical fitness, and walking on the flat ground at the same speed. Generally, calf amputation consumes 10%-40% more energy than normal people, thigh amputation consumes 65%- 100% more energy than normal people, and bilateral thigh amputation consumes1kloc-0/0% more energy than normal people. Such a large energy consumption requires lower limb amputees to have a strong body.

It is necessary to carry out intensive training of trunk muscles and amputation, strengthen back muscles and training, stand on one leg, and finally practice one-leg jumping. This can not only enhance muscle strength, but also train balance ability.

Residual limb training: including joint activity training, muscle strength training, strengthening the skin strength of residual limb (especially the load-bearing part of skin), using rib walker training and standing and walking training.

2. Training of wearing artificial limbs

(1) Training of wearing temporary prosthesis: After amputation, first determine the appropriate time to install temporary prosthesis. Temporary prosthesis should be worn as soon as possible after operation if the general condition and residual limb condition permit. The training content includes wearing temporary prosthesis training, fatigue balance training, walking training (prosthetic walking training and healthy limb walking training) and walking training.
