This is related to the patient's age, weight, living habits, living environment, work type, exercise intensity, and other factors, and cannot be generalized.
In general, the initial installer is still unstable due to the condition of the residual limb, and the muscle is further atrophied and swollen. The short-term is several months, and the length is one and a half years. It is likely that the residual limb and the prosthetic cavity will not match. When the gap between the residual limb and the receiving cavity caused by the non-synchronization is small, a sock can be appropriately placed on the residual limb to fill the gap. When the gap continues to increase, affecting the normal use of the interception, the replacement of the receiving cavity components, so as not to hurt the residual limb.
Similarly, for children and adolescents who are active and fast-growing, they will need to replace multiple receiving chamber components before the elderly develop and shape due to the ever-changing residual limbs. In addition, due to their continuous development of height and weight, multiple prostheses must be updated as needed before growth and development.
Generally, in adult patients, after replacing the receiving cavity, as long as the stable weight is maintained, it is no longer necessary to replace the receiving cavity component because the receiving cavity and the residual limb do not match.
If the patient is physically large, exercised, and labor intensive, the prosthetic life of the patient is relatively short. According to the uniform specifications of domestic industry associations, the theoretical value of the safe life of a prosthetic limb is usually set to 3 to 5 years (refers to the main joint parts, excluding the hand, the footboard, the outer decorative part, etc.), if a better joint is used Configuration, this theoretical value can be extended, it is a kind of conservative, but it is an objective and responsible attitude. Any machine will wear and have fatigue limit, not to mention the prosthesis with a small external structure and daily high-intensity and high-frequency bending, torsion, shearing, impact, friction, and other comprehensive external forces. Violation of this objective law, commitment to long-term years of use and even low cost to fulfill the promise is a short-term show, and its commitment itself is not long-lasting. This is not the promise of the most advanced prosthetic institutions in the world, and it is not promised by every prosthetic institution based on honesty.
