Amputation is the removal of a limb by trauma, medical illness, or surgery.As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene.
Fusion or absence of two or more toes are also common. [3] In humans, the disorder can be noted by ultrasound in utero to prepare for amputation after birth or complex bone lengthening surgery . The amputation usually takes place at six months with removal of portions of the legs to prepare them for prosthetic use.
Prosthetic fitting and functionality in this class can differ depending on where, between the knee and hip, the amputation exists. The lower the amputation, the greater the lever the prosthetic user has using prosthesis and the more control they have in its usage. The higher the amputation, the less control they have.
An amputation between the knee and ankle joints transecting the tibia, or shinbone, is referred to as a transtibial amputation. In this situation, the patient may retain volitional control over the knee joint. The cause of amputation may dictate the length of the residual limb and the corresponding level of control of the prosthesis.
The rate of reoperation was 22%, with screw removal done in 11.4%, nail removal done in 4.2%, revision fusion done in 3.4%, and amputation in 1.5%. [11] The review concluded that there is a good fusion rate with TTC arthrodesis using an IM nail but that the surgery has a high rate of complications. [11]
Jane Buckley, writing for the Sporting Wheelies, describes the athletes in this classification as: "Single below knee amputation or an athlete who can walk with moderately reduced function in one or both legs." [1] The Australian Paralympic Committee defines this classification as being for athletes who have the "Single leg below knee ...
Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients requiring arthroplasty, replacing the conventional use of arthrodesis, i.e. fusion of the bones.
Limb-sparing techniques, also known as limb-saving or limb-salvage techniques, are performed in order to preserve the look and function of limbs. [1] Limb-sparing techniques are used to preserve limbs affected by trauma, arthritis, cancers such as high-grade bone sarcomas, and vascular conditions such as diabetic foot ulcers. [2]
