Prosthesis is worn many years, always however left crooked right, can’t walk fast , still accompany lumbago sometimes, do not know what reason causes?

In view of the problem of leg amputee friends, YOBAND prosthesis maker sorted out some knowledge points and solutions for reference.

01 Relatively healthy leg tilt
During walking, the inner side of the sole left the ground, the distal side of the prosthesis and the proximal side of the medial side had a sense of pressure, and the upper edge of the lateral side of the receiving cavity was too loose.
The sole plane was flat, the distal end of the shell and the medial end of the shell had a sense of pressure, the receiving cavity was tilted inward relative to the prosthesis, and the upper edge of the outer side of the receiving cavity was too loose.
 
02 Prosthetics are relatively healthy
When the adduction Angle of the acceptor cavity is too large, the medial acceptor cavity will loosen, and the proximal lateral and distal medial acceptor cavities will have a sense of compression.
When the receiver cavity was tilted towards the medial side of the prosthetic foot, the medial receiver cavity was also loosened, and the proximal lateral and distal medial end were compressed.
 
03 Push your knees forward when landing too smoothly
If the receiver cavity is located in front of the prosthetic foot, the receiver cavity should be adjusted backward.
If the position of metatarsal toe joint of false foot is hind, it is footboard is inappropriate.
If the knee has the feeling of playing soft leg, it is too large buckling Angle of the receiving cavity.
 
04 Landing is too smooth when the center of gravity is pulled back excessively
If the position of the receiver cavity is too far back relative to the prosthetic foot/the buckling Angle of the receiver cavity is too small, it needs to be adjusted.
If the elasticity of the false heel is insufficient, the footboard is not suitable.
 

05 The artificial limb appears to be looped

In the process of walking, it is difficult for the prosthesis to delimit circles (internal/external rotation) or the center of gravity is excessive, which is the problem of the prosthesis height, and the height of the prosthesis should be adjusted.

General leg prosthetics can be parallel/less than 10MM.

06 Move your weight up and down

If the metatarsophalangeal joint of the foot is too close to the front/the heel is too soft/the front material of the foot is too hard, it is not suitable, need to replace other models of foot board.

If false foot and shoe are maladjusted, metatarsal toe joint is difficult to flex, need to adjust.

07 Waist pain when walking

In the process of walking, lumbago, if there is no correlator disease/sudden movement caused by excessive, it is a serious problem on the prosthesis line.

08 False foot rotates when heel hits the ground
If the receiving cavity of a groin is out of shape, that's the fault of the receiving cavity and it needs fixing.
If the heel is excellent, there is no room for subsidence, it is necessary to adjust or replace a more appropriate footboard.
If the heel is too hard/buffer elasticity is too strong, it can be adjusted or replaced with a more suitable footboard.
If the feet and shoes do not fit well, adjust.

The above are prosthesis alignment and adduction and abduction, flexion and other prosthesis components problems, on the basis of these problems have been solved, wearing painful/skin wear indicates that you have a great problem with the receiving cavity.
For example, hypertrophy/blackening/dryness of the extremities, swelling and pain of the patellar ligament, excessive pain/black marks at a certain point of the extremities, etc., are all "prosthesis diseases" accumulated over a long period of time by wearing inappropriate receiving cavities.
The only way to solve these problems is to find the right prosthesis maker to redo the receiver cavity.
The receiving cavity is the soul of the prosthesis, and it is also a technical job, not serious/careful to make the appropriate cavity.
To find a professional team, to share a better experience.
 
USA YOBAND prosthetic innovation technology is shared, focusing on financial and material resources, focusing on and producing its own research and development, giving full play to its unique core competitive advantages, and fully integrating global resources with international peers for the benefit of disabled friends! So when selecting a prosthetic company, the amputee who installs prosthetic limbs must investigate on the spot to determine whether the prosthetic company really has a technical team to make a prosthetic receptor cavity. The qualified prosthetic receptor cavity plays a key role in their own comfortable experience and prosthetic walking gait.
