Rotator cuff is a common venous system disease, the most obvious symptom is ulceration. In the early stage of the disease, ulcers often do not occur, and patients often just feel soreness and fatigue of the lower limbs, some dorsum of the foot or ankle edema, and the symptoms are aggravated after standing and walking for a long time. If left untreated, the lower calf and ankle skin is rough, atrophy, thinning, shiny, sparse sweat hair, color deepening black, hyperpigmentation, eczema, often flaking, itching, to the point of ulceration. The early stage of ulcers may just be inflammatory material oozing out, followed by skin ulceration, the old is not good, the more rotten the bigger, the more rotten the deeper, and ultimately the skin will be rotting the whole layer of the skin, and the ulcers are serious and even cancerous. In front of the middle and lower part of the calf, the skin is very thin, and the bone is under the skin, once the ulcer occurs, the bone will be exposed, and it will be easy to be infected to the deep from the surface, forming chronic osteomyelitis, and finally the limb has to be amputated. Many patients suffer from ulcers for years and decades and suffer a lot. Old rotting leg seriously affects the patient’s normal life and damages the patient’s health. How is the old rotting leg caused? What are the causes of rotting leg? Old rotting leg is mainly lower extremity ulcers, and 95% of lower extremity ulcers are caused by ischemic, depressive or neurological causes: 1, ischemic ulcers occur on the distal side of the limb that is toes (fingers) and the root of the foot, the pain is severe, especially at night, the pendulous limb can be relieved, the edge of the ulcer began to be irregular, and then jagged, the bottom of the greyish-white unhealthy granulation tissue cover, the surrounding tissue is chronic ischemia. 2.Depressed ulcers occur in the lower and middle part of the calf, single or multiple, round or irregular shape. The ulcers are shallow, with hard edges, slope-like, the granulation tissue at the bottom is relatively loose, the surface is uneven, and covered with purulent secretion. The surrounding skin is dark brown hyperpigmented with edema, eczema, itching and other signs of depressive dermatitis. The pain is mild and relieved after elevating the affected limbs and cleaning the wound. 3.Neuropathic ulcers occur in the metatarsophalangeal joints, ankle joints, callus pressure, root of the foot, small toe joints and other places. The ulcer is round, the edge is fence-like, the cavity is deep and has rough granulation tissue, the secretion is thin and has bad smell. The surrounding tissues can be atrophied, often without obvious pain. What are the serious harms to human body? “Rotunda is medically known as venous ulcer of the lower limbs, which is a common complication of venous lesions of the lower limbs. Rotator cuff is mainly a chronic skin ulcer in the lower and middle part of the calf. At the beginning of the disease, the skin is only inflammation oozing, followed by ulcers, ulcers are not easy to heal, the more rotten the bigger, the more rotten the deeper, and ultimately the skin will be rotted, the skin around the ulcer is affected, atrophy, black color, causing eczema, flaking, itching. The consequences of untimely treatment of old rotting leg are serious. What are the dangers of rotting leg? 1, the old rotten leg may cause osteomyelitis calf in front of the lower part of the lower, under the skin is the bone, once the ulcer occurs, long time does not heal, may invade the bone, bone exposed, and then infection occurs, the formation of chronic osteomyelitis. Some patients do not heal for several years, more than ten years, the ulcer surface is dripping with pus. 2, old rotten leg may cause lymphangitis Acute lymphangitis is an acute inflammation of lymphatic vessels and their surrounding tissues caused by the spread of pathogenic bacteria from the broken skin or infected foci to the neighboring lymphatic vessels. Because the ulcer surface is not healed for a long time, the pathogenic bacteria spread to the neighboring lymphatic vessels from the infected foci, which may cause lymphangitis and its surrounding tissue inflammation secondary infection. 3, old rotting leg may cause cancer The characteristics of old rotting leg is not healed for a long time, easy to recur after healing, repeated ulcers or ulcers for many years have the possibility of malignant transformation, that is, the so-called cancer. So we need to timely and correct treatment. 4, the old rotten leg may cause dengue dengue is good in the lower limbs and face. The old rotten leg is a chronic skin ulcer in the lower and middle part of the calf. As the ulcer surface is not healed for a long time, the pathogenic bacteria from the infected foci spread to the neighboring reticular lymphatic vessels and lymphatic vessels around the tissues, secondary infection caused by dengue. 5, the old rotten leg can lead to amputation The old rotten leg is a common complication of venous lesions of the lower extremities, mainly chronic skin ulcers in the lower and middle parts of the calf. Generally does not lead to amputation, but when rotting leg complicates serious osteomyelitis and cancer, then need to do amputation surgery to save life.
