IF IT may be postulated correctly that the most satisfactory artificial leg is the one which most nearly simulates the static and dynamic behavior of the natural limb it replaces, the successful practice of lower-extremity prosthetics poses a twofold requirement. The first is an intimate and detailed knowledge of the characteristics of the normal leg in all common activities, and the second is ...

This paper describes the surgical technique of the Krukenberg procedure being applied in the Artificial Limb Centre, Pune, India. The results of 95 amputations on 56 patients are examined with respect to cause, age and sex distribution, and level of amputation. The benefits of this amputation to the bilateral amputee are discussed.

Ir. 1800, James Potts of London produced an artificial leg with an articulated knee and ankle, and the ankle even had a 'toe lift' during the swing phase. The leg acquired fame by being provided for the Marquis of Anglesea, who had an above-knee amputation at the battle of Waterloo in 1815. The limb bears a remarkable resemblance to those produced today. Verduin, in 1696 produced a below-knee l...

A successful above knee amputation. The patient was walking on crutches within 10 days of operation. He had run eight miles a day until acute thrombosis of a popliteal aneurysm produced irreversible ischaemia. Most lower limb amputations are now done because of vascular insufficiency. In 1987, 4985 new lower limb amputees were referred to the disablement service centres (previously known as art...

Kinematic data wisely correlate vector quantities in space to scalar parameters in time to assess the degree of symmetry between the intact limb and the amputated limb with respect to a normal model derived from the gait of control group participants. Furthermore, these particular data allow a doctor to preliminarily evaluate the usefulness of a certain rehabilitation therapy. Kinetic curves al...

The gait patterns of unilateral below-knee amputees wearing prostheses with either a SACH foot or a single axis foot were compared. A temporary below-knee prosthesis was fabricated for each subject using plaster of Paris and Plastazote for the socket, a pylon and an artificial foot. Eight subjects were filmed at two separate sessions, one in which the SACH foot was worn on their prosthesis and ...

Urodele amphibians are unique among adult vertebrates in their ability to regenerate complex body structures after traumatic injury. In salamander regeneration, the cells maintain a memory of their original position and use this positional information to recreate the missing pattern. We used an in vivo gain-of-function assay to determine whether components of the extracellular matrix (ECM) have...

The Ilizarov fixator can be used as a bone regenerator to correct limb-length discrepancies in patients who require limb lengthening.A 17-year-old man presented with 12 cm of left lower-limb shortening and amputation at the left mid-forefoot region, which was the result of severe burns of the left lower limb at 2 years of age. The burns damaged the distal femoral, proximal, and distal tibial ph...

Functional morphologists have traditionally regarded cost of locomotion as an important influence on the design of locomotor structures. If cost of locomotion is an important constraint in the natural selection of these structures, it should be possible to show that animals differing in limb morphology also differ in their locomotor costs. In previous experiments on three species of cursorial m...
