Application of temporary prosthesis
Application of temporary prosthesis
Temporary prostheses are simple prostheses composed of a temporary residual limb receiving cavity and other prosthetic components such as mechanical knee joints, connectors, and artificial feet. Temporary stump receptacles are mostly made of plaster bandages, or they can be made of resin materials. The former is heavy and cheap, while the latter is light and expensive. Temporary prostheses are mainly used for early postoperative prosthetic installation. Early standing is very helpful for amputees to restore their body balance, reduce phantom limb sensation, and recover early.
1. Assembly time:
The traditional method of prosthesis installation in my country is to wait for the wound to heal after the amputation, remove the stitches, and wait a few months or six months after being discharged home. The residual limb edema disappears, and the prosthesis is not considered until the residual limb is finalized. In order to help the amputee to recover quickly, it is advocated to install temporary prostheses early in modern times. The general temporary prosthesis can be installed after half a month after the amputation, the wound heals well and the stitches are removed. There is also a plaster bandage immediately after the amputation to stand under the weight-bearing cavity to reduce edema.
2. Use temporary prostheses
When wearing a temporary calf prosthesis, it is generally necessary to put several layers of stump sock on the stump, then pass the bottom end of the stump sock through the bottom opening of the temporary receiving cavity, and then pull the stump into the receiving cavity. After a few days of wearing it for a few weeks, the residual limb needs to increase the number of socks after the swelling and thinning.
When wearing a temporary thigh prosthesis, first apply some talcum powder on the residual limb, and then put on a silk material called roll-up. This material can reduce the friction on the residual limb during wearing, and then the residual limb The bottom end of the sock is passed through the bottom hole of the temporary receiving cavity, and then the residual limb is pulled into the receiving cavity. After a few days of wearing it for a few weeks, the residual limb needs to increase the number of socks after swelling and thinning. The temporary receiving cavity of gypsum material can be filled with plaster on the inner wall of the receiving cavity when the limbs become thin. For the receiving cavity of resin material, some foam pads of corresponding thickness can be glued on the inner wall of the receiving cavity to adapt to the thinning residual. limb. For amputees with unsatisfactory residual limbs, especially the elderly, children, and women, in order to reduce the weight of the prosthesis and make it easier for the prosthesis to adapt to the receiving cavity, a resin material or polymer material bandage can be used to make a temporary prosthetic receiving cavity.
3. Advantages of using temporary prostheses
After the patient's limb is amputated, some doctors are more conservative because they have to wait for the wound to heal. They don't know the time of prosthesis installation very well. The patient's doctor's advice is to consider installing the prosthesis after three months. Within three months of waiting for recovery, patients mainly rely on crutches or wheelchairs to transfer. Most of the muscle strength of the residual limb after amputation is unbalanced, which will lead to the adduction, abduction or flexion deformity of the residual limb, which will cause the patient to assemble the prosthesis. Great influence. In addition, most patients have phantom limb pain and residual limb pain after amputation. The patient's skin pressure resistance and weight-bearing ability training at the bottom end are all factors that affect the later assembly of formal prostheses.
Assembling temporary prostheses can bear weight as soon as possible, prevent joint flexion and abduction deformities, improve the overall condition, and prevent complications caused by prolonged bed rest; stand and walk training using prostheses can be carried out as soon as possible. Shorten the recovery time; the prosthesis maker can designate a formal prosthesis that is more suitable for the patient to wear through the observation and modification of the temporary prosthesis; it can also promote the early finalization of the residual limb and customize the formal prosthesis as soon as possible. Clinically, after wearing a temporary prosthesis for two weeks, there is no change in the circumference measurement of the residual limb or the prosthesis no longer adds socks, the plaster receiving cavity and the resin receiving cavity are no longer filled with materials, it can be regarded as the residual limb is basically shaped. Customized formal prosthesis.
Nowadays, when prosthetic orthotics manufacturers make formal prostheses, they usually give patients an additional receiving cavity. This receiving cavity is replaced after the patient wears the formal prosthesis for about half a year, because the limbs generally become thinner after the formal prosthesis is worn for half a year. The size of the receiving cavity that is replaced at the time is basically the size of the receiving cavity of the patient wearing a prosthesis for a long time.
