چکیده
1 Previously published in Orthopadie Technik, 4/76, 58-60. Introduction M o r e than twenty years ago, McLaur in (1954) published his first report on the Canadian hip disarticulation prosthesis. His work was aimed at improving the conventional design of the saucer-type and tilting table prostheses. A measure of his success can be seen in that the Canadian-type has made the other two almost obsolete. Since its introduction, the prosthesis has changed very little. Modifications have been made to the socket and hip joint , but the principles have remained the same. T w o papers have been published to date which deal with the biomechanics of the prosthesis, Radcliffe (1957) and McLaur in (1969). Al though bo th authors gave an indication of force directions, it was not possible for either to indicate magnitudes since no experimental results were available at that time. The test reported here provides quantitative information on the variat ion with time of hip, and knee moments in bo th antero/posterior and medio/lateral planes, axial torque and axial force in the shank during the stance phase. There are two main features in McLaur in ' s prosthesis compared to the other types:

OBJECTIVE To present a retrospective study of 16 patients submitted to hip disarticulation. METHODS During the period of 16 years, 16 patients who underwent hip disarticulation were identified. All of them were studied based on clinical records regarding the gender, age at surgery, disarticulation cause, postoperative complications, mortality rates and functional status after hip disarticulat...

Purpose: Hemipelvectomy amputation is a surgical procedure in which the lower limb and part of the pelvis are removed. Although few studies are available on the performance of individuals with hip disarticulation while walking, there is no study on gait analysis of hemipelvectomy subjects. Therefore, this study aimed to evaluate the gait and stability of an individual with hemipelvectomy amput...

Severe peripheral vascular disease, ma lignant tumor, or trauma occasionally re quires the performance of a very proximal lower limb amputation. When proximal amputation is performed in young people, it is expected that they will be able to am bulate with a prosthesis. Occasionally, however, the amputation surgeon is con fronted with the older patient who requires amputation at the hip disa...
