Our first choice of donor site for children still in diapers is the buttocks discount tenormin 50mg without a prescription. This allows for a hidden donor site and use of the diaper to hold the silver sulfadiazine in place for wound care order tenormin 100mg without a prescription. The use of the buttocks in others is not forbidden, but we have found that it is more painful in older patients than other sites and wound care is more difficult. It is less difficult to harvest because the femur provides excellent support during harvesting and there is minimal motion even with ambulation so that the dressings remain intact during the healing period. The lower back is another area that is less difficult to harvest and provides ample skin. The difficulty with using the lower back is that most often it requires a patient to change position during the operation. The use of clysis can help provide support to the area to be excised so that the best donor may be harvested. We use lactated Ringer’s solution to inject and use clysis on any site that needs additional support, especially the abdomen and chest. Using assistants to provide traction to the skin and surgical soap for lubrication can also help. Donor site dressings Before we started our process of early excision of indeterminate burns, many patients endured weeks of daily debridement and donor sites were not a problem. With the pain of daily debridements gone, since the burns were excised, this left larger donor sites to cover the excised wound and now the patients focused on their donor site pain. Over the past 20 years, our institution has used many donor site coverings. We also went through periods using petroleum-jelly-impregnated gauze, adhesive polyurethane sheets, calcium alginate, Biobrane (Bertek Pharmaceuticals, Inc), and others. We 146 Heimbach and Faucher now most commonly use Acticoat (Smith and Nephew) for most donor sites. We use silver sulfadiazine cream on buttock donors of children in diapers and on donor sites near unexcised burns treated with silver sulfadiazine. We have found Acticoat to be more cost-effective, provide better patient tolerance, and better pain control than other dressings we have tried. To use Acticoat effectively, we follow the application technique for small donor sites as follows: 1. Cut Acticoat to cover the entire donor site to include at least a 2 inch border covering normal skin and place the dry Acticoat on the donor site.

This is a natural process that enables the bone to be strengthened during correspond- ing loading. On the other hand, the sustained absence of loading will lead to a predominance of the resorption process and thus to osteoporosis. Any subsequent local overloading that occurs will lead to an imbalance between resorption and new bone formation and thus to a stress fracture. Periosteal and endosteal proliferation in the sur- rounding area attempt to compensate for the weakening of the bone, which leads to characteristic sclerosis of the bone surrounding the resorption zone. Etiology, history A triggering factor is repetitive trauma, usually caused by the excessive practicing of a particular sport. Load-related symptoms that worsen as the load increases and the ab- sence of pain at night are characteristic of stress fractures. This point is extremely important for the differentiation from an osteoid osteoma, primarily chronic osteomyelitis or even a Ewing sarcoma, any of which can appear very similar in the imaging investigations.
