There are three technological grades of Consider a through-knee amputation in any frail and prosthesis; of these the third is not necessarily the worst buy discount levitra 20 mg on line. An emergency amputation for sepsis or crushed limb may best levitra 10 mg, Do not despise these; when well made they last longer however generic 20 mg levitra amex, save someone from the jaws of death! Remember that the Many patients (particularly labourers and even some patient may be used to sitting on the floor rather than on a surgeons) hardly miss an amputated finger, for example. If you decide to amputate, discuss the decision carefully To this end, the Jaipur prosthesis is most suitable. If he is going to take a long time to It does not require any shoe: amputees can walk barefoot, recover, tell him so. It is made of waterproof material, difficult decision has to be made, let him share it. If he is involved in the decision, he is much more likely to It permits enough foot dorsiflexion and other movements be enthusiastic about subsequent rehabilitation. A leg prosthesis can: Fish mouth flaps must be long enough to cover the soft (1), have a cup to bear weight on the sides of the stump, tissues of the stump, but not be so long that their blood in which case the scar should be at the end. If the flaps are (2),bear weight on the end of the stump, in which case the equal, the scar will sit at the end of a stump. Higher up the vary in their scope and preferences, so visit your local one arm the scar can be anywhere. A good prosthetist can fit any on the kind of prosthesis envisaged: end-bearing, well constructed stump with a prosthesis. In the lower arm and leg, transverse scars are better than antero-posterior because they do not get drawn up between the two bones. Also, a guillotine amputation may not differentiate between healthy and septic or irreparably damaged tissue. Therefore, you will lose more length with a guillotine amputation as you need to shorten the bone again to be able to cover it with muscle and skin. The leg stump must be prepared for the prosthesis, and you need to teach the patient how to use it. Firm bandaging will hasten change of the stump from a bulky cylinder to a narrow cone, and exercises will strengthen the remaining muscles. After a lower leg amputation, for example, learning to kick a large rubber ball about is very therapeutic. Avoiding a flexion contracture of the knee is essential after a below-knee amputation. If there is already a tendency to flexion, keep the knee in a backslab or cast until full mobilization. Disarticulate a joint if you can, especially at the knee, because this will preserve its epiphyses. Removing a limb by amputating through the shaft of a bone produces an effect which varies with the site. In the arm save every centimetre in the childs upper arm, and at the joints so as not to affect growth; choose the longest feasible amputation in the adult arm; in the leg amputate at the classical sites only. Delayed primary closure is always wise: (1) if the limb is already infected, or may soon be so. If you decide on delayed primary closure, cut the flaps long, to allow them to retract. Leave the muscle and fascia unsutured, bandage the skin flaps over dry gauze swabs, do not put in any sutures, and inspect the wound 3-5days later. If it is infected, debride it and leave the flaps open for 1-2wks, and close it only when it is clean. The long posterior flap technique is the standard for the If necessary, you can use any sterilizable saw or domestic knife. The back of the saw stiffens it during the early part of the cut, but can be In the leg, equal anterior & posterior, or lateral flaps are hinged back later to let the saw pass through. A Gigli bone saw is a piece of wire with sharp teeth on it which you pull to and fro between two handles. In these cases, you need not worry so much about ischaemia and can use a tourniquet, but do not exsanguinate the limb with an Esmarch bandage (3-6L) where there is sepsis or malignancy. Release the tourniquet before you suture the muscles, so that you can tie any bleeding vessels before you cover them. For ischaemic limbs, try to use epidural anaesthesia, which causes vasodilation and improves peripheral blood flow. For equal flaps, make the length of each flap equal to of the diameter of the limb (35-8A). For unequal flaps, make the longer flap equal to the diameter of the limb, and the shorter one equal to its diameter (35-8B). As a general rule the combined length of both flaps should equal 1 times the diameter of the limb at the site of the bone section. Cut through the skin down to the deep fascia, and reflect this up with the skin as part of the flap. Minimize trauma to the flaps: handle Together, the flaps should be 1 times the diameter of the limb. C, reflect the skin with the deep fascia and cut the muscle 8cm distal to the bone section. E, the deep fascia closed over the bony trim them if they are too long later, but you cannot stump, protecting it with muscle. Cut the flaps as far distally as you can, so that you can (4),Make sure the scar is not at the end of the stump if that refashion them later. Cut the skin down to the deep fascia limb will carry the pressure of a prosthesis. Cut them long enough stump with vaseline gauze, betadine and plenty of dry for this but do not leave so much muscle that the stump gauze. Leave them a little longer if you are using delayed primary closure, because they will have more time to shrink. Use a long sharp amputation knife or kitchen knife to cut the muscles straight down to the bone. Do not use a scalpel which makes many small cuts, and leaves shreds of injured muscle. If the muscles look unhealthy when you cut them, abandon the operation at that site, and amputate higher up. Instead, gently pull each nerve into the wound, cut it cleanly with a knife, then let it retract above the amputation site. The sciatic nerve is accompanied by an artery which may bleed profusely, so tie the artery off carefully, separately from the nerve. Reflect this proximally only for 1-2cm with the muscles, so as to expose bare bone. This is quick and the flaps are less likely to necrose if the blood and maintain a steady smooth movement to prevent the supply is poor, but a revision is almost always necessary later. Later, after you have removed the limb, tie the remaining Cut the muscle first, or retract it well out of the way with a smaller vessels. If the limb is very fat, cautiously remove as much subcutaneous fat as is necessary. If you cannot find them, wash the wound with hydrogen If oozing continues, insert a suction drain, or less peroxide. In desperation, pack the wound with dry gauze, satisfactorily, leave part of the wound open for drainage. This may be disastrous in ischaemic If the stump becomes infected, open the wound, irrigate tissues. Always consider If you are amputating for chronic or severe acute sepsis delayed primary suture if there is an increased risk of or for a traumatized limb with much foreign material infection. If a persistent sinus develops in the stump, explore it; you may find a piece of necrotic tendon, or an area of Suture the skin and deep fascia separately. Dress the stump firmly, Explore the stump, remove all dead and dying tissue, but not too tightly. A plaster covering will make an If the flaps break down, you probably cut them too short above-knee stump more comfortable and its weight will or closed them too tight. The final quality of the skin over the stump will be worse Remove sutures after 7days for the hand & arm, than it would have been if the flaps had survived, and it and 14days for the leg. If there is spreading sepsis or gas gangrene, Do not allow a knee flexion or hip flexion contracture to amputate higher up immediately, through the shoulder or occur. Mobilize the patient early; if you can fit a hip if need be, and leave the wound open. You will thereby avoid the development If a prosthesis cannot be fitted, you have probably of pressure sores. The reasons include: (1) bone adherent to the scar, As soon as a lower limb stump has healed, bandage it. If you amputate higher up, If there is no hope of an elbow prosthesis, leave as much a convenient place is 18-20cm below the acromion. Trim the triceps tendon to If you can leave a reasonable length of humerus, make a long flap, carry it across the end of the bone, and it can be used to hold things by gripping them against the suture it to the fascia over the anterior muscles. If you have to amputate very high up, even a very short stump will preserve the outline of the shoulder. If you can provide a prosthesis, do not amputate through the lower 4cm of the humerus, because it will be difficult to fit.

While ity of breaking the tissue in which they belong, they genetic compositions remain constant upon migration, become malignant and further capable of invading environmental and lifestyle factors are subject to other tissues. One evidence of the major role of environ- blood or lymph vessels and lodge in a distant site. Cancers of the breast, prostate, colon, cancer deaths are the result of metastasis. Some of the factors asso- controlled mainly by two groups of genes, proto- ciated with differences in cancer incidence across oncogenes and tumor suppressor genes. Proto- of children associated with increased breast cancer oncogenes are responsible for the stimulation of growth risk) and nutrition (i. Mutation of these genes therefore will result in site is true for cancers of the cervix, stomach, liver, overgrowth of cells. Nonfunctional tumor suppressor genes will allow and esophagus), heavy alcohol consumption (liver inappropriate cell reproduction. Although mutation in (Helicobacter pylori and stomach cancer) associated these two groups of genes contributes remarkably to with several cancers seems to be higher in less affluent the development of cancer, involvement of other muted populations. It and further detach from its residence and spread to was estimated that in 2003, over 1. The to cancerous cells requires a relatively long process of cancer-related economic burden to the society is accumulation of several muted genes over time. Overnutrition during childhood mechanism for some of these factors by which they that leads to disproportionate growth may lead to contribute to cancer remain elusive, results from epi- increased risk of cancer through adulthood. This has demiological studies provide clear evidence of their clearly been shown in epidemiological studies of breast major role in cancer causation. There is sufficient evidence of the role of physical activity on the prevention of breast (see Breast cancer) and colon cancer and probably cancers of the endometrium (lining of the uterus) and prostate. Individuals with fair skin are more susceptible to More than 25% of all cancer deaths could be the carcinogenic effect of sunlight. The risk is accelerated among lung cancer but also that passive smoking is a major smokers.
