prosthetic limbs leg as an industrial product, in the use of the process of failure is also a normal phenomenon, but in order to ensure the safety of the use of prosthetic limbs leg, failure should be found out and solved in time, so as to avoid causing greater losses. As a modern industrial product, prosthetic limb plays a certain compensatory function for the body's incomplete part, because the assembly of prosthesis is is carried out in professional prosthetic assembly company, and the actual use of life according to the use of amputees, there are some small problems also belong to the normal phenomenon, so how can patients effectively deal with these small problems?　

1、 The receptive cavity is becoming more and more unsuitable. I always feel that the prosthesis will fall off. This kind of condition is mostly caused by limb atrophy or lining material thinning after a long time of use. Properly increasing the thickness of stump socks can basically eliminate the fault, and the good solution is to replace the socket.　

2、 There is noise at the joint of pipe fittings. In case of noise, you can first check whether the fixed screw at the connection of the pipe fitting is loose. In many cases, because the contact surface of the fixing screw is too small and the strength is not enough, after a period of use, the contact is not in place. After fixing the fixed screw with a special screwdriver, it can be basically eliminated. There is also a case that there are some problems in the connection of the integrated pipe, which needs to be repaired by the assembly unit at this time.

3、 When walking, it takes a lot of effort or people rush forward. This condition is usually caused by changes in the heel height of the shoe. If the height is lower than the original heel, it will be hard to step. If the height is higher than the original, it will lead to the situation of walking forward. The temporary solution is to put a little something under the heel or forefoot of the foot. However, we should remind everyone that hard objects should not be padded to avoid damaging the foot board. The cushion is only temporary adjustment, and wearing suitable high-heeled shoes is the key.
