It is very important to choose the prostheses with multiple functions and good quality. More importantly, to choose the prostheses suitable for the amputee's own characteristics, it must be suitable for the amputee's physical condition, the condition of the amputee's stumps, the amount of activity and the living and working environment. Disabled friends should not only pay attention to the knee joint, but also pay attention to the selection of prosthetic foot, ankle joint, elastic torsion device and other functional parts which can be adjusted according to the characteristics of amputee. Only by using prosthesis can we give full play to the function and replace the function of the lost limb, which is the proper conclusion.
The tolerance of the skin and tissue of the amputated limb to the receiving cavity will be the fundamental basis of the amputee's walking function. Good stumps can be judged from the following aspects:
① The shape of the stump is suitable for the skin condition of the stump (such as no ulcer, large area skin grafting, etc.)
② The shape of the stump above or below the knee is better to be inverted cone, and the skeleton is better not to have any bending deformation
③ The end of the stump should have enough soft tissue as a pad to ensure the effective length of the stump
④ The end of the skeleton of the stump must also be moderately trimmed. For the amputee under the knee, the fibula should be shorter than the tibia to avoid excessive pulling force on the skin at the end of the stump.
In order to achieve these conditions, in addition to the operation of bone repair and good muscle fixation. In addition, it is the most important way to let patients receive good and gradual rehabilitation treatment as soon as possible. This will not only create good conditions for the assembly of prosthesis, but also lay a foundation for its future recovery of life and work.
Walking posture and walking ability are important indexes to judge whether the prosthesis can adapt to the amputee. Walking posture is important, and walking ability can not be ignored. Walking ability is directly related to the amputee's ability to work, live and move after wearing the prosthesis. Only selecting the prostheses suitable for the amputee's own characteristics can improve the walking ability, make the amputee self-reliance, step by step towards comprehensive rehabilitation.
