Management of amputation-stump breakdown.

Seven cases of above-knee amputation stump breakdown following surgery for arteriosclerosis obliterans were successfully treated with Travase ointment. (Bacillus subtilis proteinase). Rehabilitation was facilitated because secondary closure of the previously infected necrotic wounds could be more rapidly undertaken.

Amputation stump management. A preliminary report on the use of shrink plastic film as a surgical dressing in amputation surgery.

This report describes the use of clear plastic bags on vinyl chloride-vinylidine chloride copolymer (also known as S Film) for the postoperative management of amputation stumps. The bags are shrunk to the stump by the application of heat and act as a primary dressing. Their use has been effective in controlling postoperative oedema and infection as well as giving the surgeon direct visual access to the stump without disturbing the wound. A case of a below-knee amputation managed by this method is described.

The vascularization in the amputation stumps of rabbits. A microangiographic study.

With the aid of microangiography the vascularization in the amputation stumps of 108 rabbits was studied, both in extremities with normal circulation and in those supplied with collaterals. It was found that the vascularization of the normal leg was altered by amputation, with the development of newly-formed, pathological, spirally-twisted vessels. Closure of the stump with myoplasty, however, counteracted this vessel formation, and hypervascularization took place through normal arteries. After amputation of extremities supplied with collaterals, the influence of amputation on collateral function and vascularization in the amputation stump was dependent on the time interval between arterial occlusion and amputation.

Bone vascularization and bone healing in the amputation stump. An experimental study.

The osseous healing process of the amputation stump was investigated in adult rabbits. Histological investigation showed that the medullary cavity was closed after 2-3 weeks, chiefly by endosteal callus. After closure of the cavity there was a gradual spongious change in the bone tip and simultaneously the cortex atrophied and the medullary cavity dilated. After amputation on the crus bone rebuilding dominated, whereas after amputation on the femur deterioration of bone was most noticeable. A combination of amputation and medullary plugging caused a change in the course of healing. The medullary cavity did not close until 7-10 weeks after operation and there was distinct periosteal callus formation. The microangiographic investigation showed a transient hypervascularization in the cortex 3-4 weeks after amputation; whereas after simultaneous plugging of the medullary cavity the hypervascularization continued for up to 7 weeks after operation. Following amputation proximally on the crus the arterial supply of the cortex came mainly from the periost, whereas the cortex after distal amputation was vascularized from the medullary cavity. This finding can be due to an interruption of the arterial supply from the nutrient artery associated with proximal amputation, whereas this artery remains intact with amputation distally on the crus.
