It has a great relationship with the patient's age and gender. Normal adults amputated for 8- 10 months, and the wound recovered completely. Theoretically, the swelling around them has subsided. It is suggested to assemble the prosthesis immediately, because the rejection reaction of the human body is not as strong as that of the healing period, and the muscles of the residual limb have not shrunk obviously. This is the best time to install artificial limbs.

If it is a minor, the time should be relatively advanced. In addition to the above reasons, children are faster, but also because children are playful, their residual limbs are exposed, and they are easily injured. Installing artificial limbs early will reduce the psychological impact on children.

Precautions before and after installation:

1, after amputation, keep the muscle strength training of the residual limb as much as possible to prevent atrophy.

2. It is necessary to equip artificial limbs according to your own situation. If there is obvious discomfort, strong friction and obvious allergy of the residual limb, it needs to be adjusted.

3. It belongs to the running-in period within 1-3 weeks after prosthesis installation. At this time, we should pay attention to gradually expanding the scope of activities. Don't do too strenuous exercise to prevent residual limb injury.

4, pay attention to the value maintenance and cleanliness at ordinary times, regular disinfection.

5. If it is a child's forearm amputation, he has a certain muscle strength over five years old and can assemble an electromechanical hand. Electromechanical hand has a certain weight, which can be controlled by forearm hand muscles, which is beneficial to the recovery and growth of children's residual limb muscles.
