Is there a requirement for the length of the residual limb for persons with disabilities to pretend to have a prosthetic limb?

It depends on which part of the limb needs to be amputated, and the optimal amputation site varies for each part.

Requirements for amputation plane:

Traditional concept: amputation must be performed on a specific plane in order to assemble the prosthetic.

. According to anatomy, it can be divided into upper arm amputation (elbow amputation), forearm amputation (elbow amputation), thigh amputation (knee amputation), and lower leg amputation (knee amputation). Modern requirements include full contact receiving chambers and prosthetic installation technology, and the amputation plane is no longer important. Any amputees with good healing, no tenderness, and appropriate construction can be satisfactorily fitted with prosthetics. The amputation plane is mainly determined by the surgical needs.

The most important principle for amputation of other limbs, except for calf amputation, 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: keep the residual limb length as much as possible

Elbow amputation: elbow joint detachment is the ideal amputation site

Forearm amputation: keep the length as much as possible

Wrist amputation: wrist joint or wrist joint detachment

Palm and finger amputation: keep the length as much as possible, especially the thumb should be kept as much as possible

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

Hip amputation: keep the femoral head and neck as much as possible

Thigh amputation: keep the length as much as possible Preservation of residual limb length

Lower leg amputation: preferably at the junction of the middle and lower thirds

Syme amputation: an ideal amputation site, the amputation level is equivalent to ankle joint detachment, but the residual end is covered by intact and good heel skin, so the residual limb has good load-bearing capacity and walking ability.
