Is there a requirement for the length of the prosthesis for the disabled to install the prosthesis?

 

Requirements for amputation plane: Traditional concept: amputation must be performed on a specific

plane in order to assemble the prosthesis. According to anatomy, it can be divided into upper arm amputation

(upper elbow amputation), forearm amputation (lower elbow amputation), thigh amputation (upper knee amputation),

calf amputation (lower knee amputation). Modern requirements: full contact cavity and prosthetic installation technology,

the amputation plane has been unimportant. Any amputation stump with good healing, no tenderness, and proper

structure can be satisfactorily worn. The amputation plane is mainly determined by the needs of the operation

 

Except for calf amputation, which should be at the junction of the middle and lower thirds, the most important principle for other limb amputations is to preserve the length of the limb as much as possible through intraoperative judgment. Cylindrical stump.

Shoulder amputation: Keep the humeral head as much as possible.

Upper arm amputation: try to keep the length of the residual limb

Elbow amputation: elbow joint amputation is an ideal amputation site

Forearm amputation: try to keep the length

Wrist amputation: detached through the wrist joint or wrist joint

Palm and finger amputation: try to keep the length, especially the thumb should try to keep the length

Hemipelvic resection: try to preserve the iliac crest and ischial tuberosity according to the conditions

Hip amputation: the femoral head and neck should be preserved as much as possible

Thigh amputation: try to keep the length of the residual limb and knee severance

Calf amputation: the middle and lower 1/3 junction is better

The same amputation: It is an ideal amputation site. The amputation level is equivalent to that of the ankle joint,

but the stump is covered by intact and good heel skin.

Therefore, the residual limb has good weight bearing capacity and good walking ability. Foot amputation: try to keep the length
