Introduction

Temporary prostheses are simple prostheses composed of temporary residual limb receiving cavities and other prosthetic components such as mechanical knee joints, connectors, prosthetic feet, etc. Temporary residual limb receiving cavities are often made of plaster bandages or resin materials. The former is heavy and cheap, while the latter is light in weight and expensive. Temporary prostheses are mainly used for early postoperative prosthetic installation. Early standing is of great help to amputees in restoring body balance, reducing phantom limb sensation, and early recovery.

1、 Assembly time:

The traditional method of installing prostheses in China is to wait for the wound to heal and the stitches to be removed after amputation surgery, and then discharge home for several months or six months. After the residual limb edema disappears and the residual limb is fixed, the installation of prostheses is considered. In order to help amputees recover as soon as possible, modern times advocate for the early installation of temporary prosthetics. A general temporary prosthetic can be installed after half a month of amputation surgery, with good wound healing and stitches removed. There are also cases where a plaster bandage is immediately installed after amputation to receive weight-bearing support and stand under the cavity, in order to reduce edema.

2、 The method of applying temporary prostheses:

When wearing temporary prostheses for the lower leg, it is generally necessary to first apply several layers of residual limb socks on the residual limb, then thread the bottom end of the residual limb socks out of the bottom opening of the temporary receiving cavity, and then pull the residual limb into the receiving cavity. After wearing it for a few days and weeks, the residual limb will reduce swelling and become thinner, and it is necessary to increase the number of layers of socks. When wearing temporary thigh prostheses, first apply some talcum powder on the residual limb, then put on a silk material called pull-up bag, which can reduce friction on the residual limb during wearing. Then, thread the bottom end of the residual limb sock through the bottom opening of the temporary receiving cavity, and pull the residual limb into the receiving cavity. After wearing it for a few days and weeks, the residual limb will reduce swelling and become thinner, and it is necessary to increase the number of layers of socks. The temporary receiving cavity of gypsum material can be filled with gypsum on the inner wall of the receiving cavity when the limb is thinner. For the receiving cavity of resin material, some foam pads of corresponding thickness can be pasted on the inner wall of the receiving cavity to fit the thinner limb. For amputees with unsatisfactory residual limbs, especially the elderly, children, and women, in order to reduce the weight of the prosthetic and make it easier for the prosthetic to adapt to the receiving cavity, resin or polymer bandages can be used to create temporary prosthetic receiving cavities.

3、 The advantages of using temporary prostheses:

After amputation, some doctors are conservative and not very familiar with the installation time of prostheses. They advise patients to consider installing prostheses after three months. During the three months of waiting for recovery, patients mainly rely on crutches or wheelchairs for transfer. Most amputees have imbalanced muscle strength in their residual limbs, which can lead to deformities such as adduction, abduction, or flexion. These can have a significant impact on the patient's ability to assemble prosthetics. Another issue is that most patients experience phantom limb pain and residual limb pain after amputation. The training of the patient's skin's ability to withstand pressure and the ability to bear weight at the bottom are factors that affect the future installation of formal prostheses.

Assembling temporary prostheses can enable early weight-bearing, prevent joint flexion and abduction deformities, improve overall health, and prevent complications caused by prolonged bed rest.

; It is possible to start standing and walking training using prosthetics as soon as possible. Shorten the rehabilitation time; A prosthetic maker can specify a more suitable formal prosthetic for patients by observing and modifying the use of temporary prostheses; It can also promote the early shaping of residual limbs and the early customization of formal prosthetics. In clinical practice, after wearing a temporary prosthetic for two weeks, if there is no change in the circumference measurement of the residual limb or if the prosthetic no longer adds socks, plaster and resin receiving cavities, and no additional materials are added, it can be considered that the residual limb is basically fixed and a formal prosthetic can be customized. Nowadays, prosthetic and orthotic manufacturers usually give patients an additional receiving cavity when making formal prostheses. This receiving cavity is replaced after about half a year of wearing the formal prosthesis, because after half a year of wearing the prosthesis, the limbs generally become thinner, and the size of the replaced receiving cavity is basically the same as the size of the patient's long-term wearing of the prosthesis.
