Popliteal bypass surgery, more commonly known as femoropopliteal bypass (FPB, fem-pop, etc.) or more generally as lower extremity bypass surgery, is a surgical procedure used to treat diseased leg arteries above or below the knee. [1]
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.
Above the knee amputees have difficulty using standard able-bodied splint actions because of the differences in their functional muscle mass. As a result, they often use a specialized sprinting technique called “Leg-Over-Leg”. This technique involves using hip extensions to avoid deceleration caused by the prosthetic leg hitting the ground. [6]
An above-knee amputation partial foot amputation amputation of the lower limb distal to the ankle joint ankle disarticulation amputation of the lower limb at the ankle joint trans-tibial amputation amputation of the lower limb between the knee joint and the ankle joint, commonly referred to as a below-knee amputation knee disarticulation ...
Standard prosthetic legs for amputees cannot fully replicate the biomechanical functions of a human legs, researchers say.
In just over 10% of cases, an amputation of part of the leg is required. [4] Knee dislocations are rare, occurring in about 1 per 100,000 people per year. [3] Males are more often affected than females. [2] Younger adults are most often affected. [2] Descriptions of this injury date back to at least 20 BC by Meges of Sidon. [9]
Rarely-experienced traumas were made more common by new weaponry. This required decisive surgical action as well as the development of new techniques. As B. E. Ferrara stated in his summative article on hemicorporectomy, Lessons learned from battle field injuries quickened innovative treatment of congenital and acquired conditions ...
Even as vendors touted advantages of more complicated prostheses over simple peg legs, [3] according to a contemporary surgeon, many patients found a peg leg more comfortable for walking. [4] According to medical reports, some amputees were able to adjust to the use of a peg leg so well that they could walk 10, or even 30, miles in one day. [5]
