Temporary prosthesis is a simple prosthesis consisting of a temporary residual limb receiving cavity and other prosthetic components such as mechanical knee joints, connectors, and prosthetic feet. Temporary residual limb acceptor cavities are mostly made of plaster bandages, or resin materials can be used to make the acceptor cavity. The former is heavy and inexpensive, while the latter is light in weight and expensive. Temporary prosthesis is mainly used for early postoperative prosthetic fitting. Early standing is of great help to amputee patients in restoring body balance, reducing phantom limb sensation and early recovery. 1, assembly time: China’s traditional prosthetic installation method is to wait for wound healing and removal of stitches after amputation, discharged home and other months or six months later, residual limb edema disappears, residual limb stereotypes before considering the installation of prostheses. In order to help amputees recover as soon as possible, the early installation of temporary prosthesis is advocated in recent times. The general temporary prosthesis can be installed half a month after the amputation, after the wound heals well and the stitches are removed. There are also amputations immediately after the installation of plaster bandage to accept the cavity to stand under weight, but also to reduce edema. 2, the application of temporary prosthetic approach Wearing temporary prosthetic calf, generally in the residual limb with several layers of residual limb socks, and then the bottom of the residual limb socks from the bottom of the temporary acceptance cavity hole, and then the residual limb pulled into the acceptance cavity. After a few days and weeks of wear, the residual limb will need to be increased in number of layers as the swelling and thinning of the residual limb decreases. To wear the temporary thigh prosthesis, apply some talcum powder to the residual limb, then put on a silk material called ezra, which reduces friction on the residual limb during wear, then put the bottom end of the residual limb sock cover through the bottom hole of the temporary receiving cavity and pull the residual limb into the receiving cavity. After a few days and weeks of wear, the number of layers of the sock is increased as the swelling and thinning of the residual limb decreases. In the case of a plaster temporary receiving cavity, plaster can be added to the inner wall of the receiving cavity if the limb becomes thinner, and in the case of a resin receiving cavity, foam pads of appropriate thickness can be glued to the inner wall of the receiving cavity to fit the thinner limb. For the residual limb is not ideal for amputees, especially the elderly, children, women, in order to reduce the weight of the prosthesis and make the prosthesis easier to adapt to the cavity, you can use resin materials or polymer bandages to make a temporary prosthesis to accept the cavity. 3, the advantages of using temporary prosthesis Patients after amputation, because they have to wait for the wound to heal, some doctors are more conservative, the time of prosthetic installation is not very well understood, the patient’s medical account is three months before considering the installation of prostheses. During the three months of waiting for recovery, patients mainly rely on crutches or wheelchair transfer, most of the muscle strength imbalance of the residual limb after amputation will lead to inversion, abduction or flexion deformity of the residual limb, which will have a great impact on the patient assembly prosthesis. There is also the fact that most of the patients have phantom limb pain and residual limb pain after amputation. The patient’s skin pressure resistance and the training of the bottom end weight-bearing ability are factors that have an impact on the later fitting of a formal prosthesis. The temporary prosthesis can be fitted to prevent joint flexion and abduction deformity, improve the general condition and prevent complications caused by prolonged bed rest; the standing and walking training with the prosthesis can be carried out early. Shorten the rehabilitation time; the prosthetist can specify a formal prosthesis more in line with the patient’s wearing through the observation and modification of the use of temporary prosthesis; it can also promote the early shaping of the residual limb and early customization of the formal prosthesis. Clinically, generally after wearing a temporary prosthesis for two weeks, the circumference of the residual limb measurement no change or prosthesis no longer increase the sock, plaster receiving cavity and resin receiving cavity no longer add material, can be regarded as the basic shape of the residual limb, can be customized formal prosthesis. Now the prosthetic orthotic production unit in the production of formal prosthesis, generally will give patients an additional acceptance cavity, the acceptance cavity in the patient wear formal prosthesis after about six months to replace, because in the formal prosthesis wear six months later, the limb is generally thinner, when the size of the replacement acceptance cavity is basically the size of the patient wears a long-term prosthetic acceptance cavity.
