Methods in preventing<unk> , limb-sparing techniques, depend on the problems that might cause<unk> s to be necessary. Chronic infections, often caused by diabetes or decubitus ulcers in bedridden patients, are common causes of infections that lead to gangrene, which would then necessitate<unk> . There are two key challenges: first, many patients have impaired circulation in their extremities, and second, they have difficulty curing infections in limbs with poor blood circulation. Crush injuries where there is extensive tissue damage and poor circulation also benefit from hyperbaric oxygen therapy (HBOT). The high level of oxygenation and revascularization speed up recovery times and prevent infections. A study found that the patented method called Circulator Boot achieved significant results in prevention of<unk>  in patients with diabetes and arteriosclerosis. Another study found it also effective for healing limb ulcers caused by peripheral vascular disease. The boot checks the heart rhythm and compresses the limb between heartbeats; the compression helps cure the wounds in the walls of veins and arteries, and helps to push the blood back to the heart. For victims of trauma, advances in microsurgery in the 1970s have made replantations of severed body parts possible. The establishment of laws, rules, and guidelines, and employment of modern equipment help protect people from traumatic<unk> s.
