Studies on Amputation

چکیده
Part of a large scale investigation of amputees initiated at the Orthopaedic Clinics of Uppsala University involved corollary considerations of stump healing in experimental animals. Since the amputationofan extremity is attended with a considerablealterationofthe circulation, the problem was investigated first from a circulatory standpoint. In amputees with stump disturbances Leriche (1950) has described the presence of abnormal angiographic patterns, characterised by either hypervasculanty of the soft tissues of the stump or tortuosity of the vessels. Abeatici and Ferrero (1953) and de Sapia and Assenso (1954) have performed angiographic studies on amputation stumps of dogs, and both have found hypervascularity of the stump ends. Another problem not previously investigated is the transformation of the bony stump and the manner of callus formation. In addition some of the mechanisms of spur origin as well as pathological hyperostoses were investigated.

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...

متن کاملOutcomes in lower limb amputation following trauma: a systematic review and meta-analysis.
INTRODUCTION Lower limb amputation (LLA) is life-changing surgery. Shorter residual limbs are known to place greater physiological strain on patients than longer residual limbs; however, there is ongoing debate as to whether through-knee amputations are preferable to above-knee amputations. This analysis aims to resolve this question by systematically collecting and pooling published and unpubl...
