The early installation of prosthesis device after amputation is conducive to the reconstruction of sensory innervation and nerve feedback, prevention of muscle atrophy and joint contracture deformity, so that the residual limb can restore its previous function, expand the activity space, continuously increase physical fitness, and recover the body integrity of patients as soon as possible, which is conducive to restoring confidence and stimulating disease resistance. According to the statistical data of tens of thousands of prosthetics, whether it is trauma or swelling The earlier the prosthesis is is installed after amputation, the better the rehabilitation.

Several principles of  prosthesis device assembly are as follows

1、 The prosthetic technique should be selected and determined according to the condition of the stump and the physical condition of the patient (such as the length of the stump, muscle strength, range of motion of the joint, soft tissue and scar).

2、 We should fully consider the patient's age, working environment, living environment and psychological work requirements to determine the form and type of prosthesis.

3、 According to the patient's economic ability and current payment ability, the price grade of prosthetic limb is selected.

4、 The treatment, nursing and muscle strength training of the stump are necessary before the prosthesis is is installed.

5、 The training and adjustment of prosthesis is an important link to ensure the functional gait of patients.

6、 In the use of prosthetic limb, the assembly unit should carry out regular repair and maintenance.

7、 The quality inspection of prosthetic limb must be carried out by the prosthetic professional manufacturer assessed by the state
