How  to  wear  thigh  prosthesis- prosthetic roll up ?

    After installing a prosthesis for a lower limb amputee and performing a fit check, it must also be trained in the use of the prosthesis so that the patient can master the correct wearing method and more effectively play the compensatory function of the prosthesis. Otherwise, because the lower limb prosthesis is very different from the healthy limb in terms of weight-bearing method, control method, and range of motion of each joint, if it does not undergo a period of functional training. Once a bad gait is developed, it will be very difficult to correct it.

Now take the full-contact receptacle thigh as an example to introduce the correct wearing method:

1. Wearing method:

1. Put the prosthetic roll-up (special cover for prosthesis) on the residual limb. Note that the roll-up banner should be flat, without wrinkles, its upper edge should cover the root of the thigh, and its back should be covered with ischial tuberosity.

3. Remove the negative pressure valve on the receiving cavity.

4. Put the distal end of the roll-up banner into the receiving cavity.

5. Pass the far end of the roll-up banner out of the hole of the valve hole.

6. Insert the residual limb into the receiving cavity.

7. Stand up, straighten the prosthesis, press the prosthesis with one hand to prevent the joint from bending, and pull out the roll-up with the other hand. Pay attention to the skin feel when pulling the roll-up banner out. In addition, if the knee joint of the healthy leg can do some flexion and extension when pulling the roll-up, so that the residual limb can move up and down in the receiving cavity (that is, the residual limb can move up and down), it is easier to pull the residual limb in completely Receiving cavity.

8. After pulling out all the roll-up banners, adjust the tension of the residual limb skin around the upper edge of the cavity, and then install the negative pressure valve.

2. How to determine whether the position of the residual limb penetrating the receiving cavity is correct?

1. In the standing position, when the body weight is transferred to the side of the prosthesis, the ischial tuberosity can feel good weight-bearing; there is no tenderness in the subpubic area and adductor muscles; the end skin of the residual limb feels that it has touched the bottom of the receiving cavity but no Pain; the angle of external rotation of the prosthetic foot during walking is similar to that of a healthy foot.

2. If the ischial tuberosity does not bear weight after wearing, the skin at the end of the stump can not touch the bottom of the receiving cavity; and there are large skin folds on the inner thigh part of the stump (that is, the upper edge of the receiving cavity). These conditions may indicate The soft tissue of the residual limb was not completely pulled into the receiving cavity, and it was not completely penetrated. The prosthesis needs to be taken off and put on again.

3. If you put on the prosthesis, you find that the inner part of the residual limb is uncomfortable during standing or walking, and the prosthetic toe is rotated outward or inward too much during walking, indicating that the prosthesis is incorrectly worn or crooked and needs to be taken off and worn again. Care should be taken to ensure that the direction of the inner wall of the receiving cavity is consistent with the walking direction of the amputee when repassing.
