HISTORY OF BURN EXCISION Although early excision and grafting has been considered a procedure of the late 20th century; it was actually first described by Lustgarten in 1891. The fire at the Cocoanut Grove Nightclub in Boston in November, 1942, brought new insight into many aspects of the care of burned patients. Cope suggested then that patients with early wound closure had improved survival. Several reports are scattered throughout the literature over the next 30 years [2–4], but results were discourag- ing since they showed little clinical improvement from the usual practice of waiting for spontaneous eschar separation followed by grafting on granulation tissue. Janezekovic reported good results in 1970 with sequential shaving of burns of varying depths in. The surgical community began to take notice; however, the need to estimate the depth of burn and ancillary support required for a major burn excision made acceptance of this technique difficult. In 1978, a major change in approach to burn care was instituted: burns judged to require more than 3 weeks to heal were to be managed by excision and grafting. The patients who underwent excision and grafting had significantly shorter hospital stay, lower hospital 135 136 Heimbach and Faucher charges, and fewer infectious complications. Based on that information, a randomized prospective study was done in patients with burns of indeterminate depth. The results again found that those with excision had shorter hospital stay, lower hospital charges, fewer reconstruction surgeries, and returned to work sooner. PATIENT SELECTION FOR SURGERY Burns involving the superficial dermis heal within 3 weeks, generally without hypertrophic scarring. Since these burns generally cause no functional and little cosmetic impairment, primary skin grafting does not reduce morbidity or improve appearance and function. They will eventually need skin grafting and the sooner they are grafted the sooner the wounds will be healed. Burns that are very large, of indeterminate depth, or very deep, pose difficult questions. Extensive burns can be too large for complete excision and grafting in one operation. The use of immunohistochemisty, infrared fluorescence, and laser Doppler studies all show promise in vitro, but a trained surgeon has been shown to be at least as good. The cause of the burn, inspection and palpation of the wound, and sensory nerve function are all important clues. Finally, excision of very deep burns over joints, tendons, and bones may leave a wound that may not accept a skin graft. Some truisms regarding burns and burn care include the following: Burns in patients at the extremes of age are not shallow. Except for contact burns, most burns of the palms and soles heal within 3 weeks. Patients whose clothing or bedding has been on fire rarely escape without some full-thickness burns. All electrical burns are full-thickness and should be assumed to be fourth- degree. Flash burns are rarely full-thickness, except in areas of very thin skin. Burns from hot soups and sauces are deeper than those from hot water alone. Principles of Burn Surgery 137 Burns resulting from direct contact with a tar pot are usually very deep dermal or full-thickness burns, while those from tar that has been trans- ferred into a bucket or spread on a surface are usually shallow.
Treatment of metaphyseal bowing fractures of the proximal tibia: By definition order 400 mg levitra plus with mastercard, every metaphyseal bowing fracture involves an axial devia- tion generic levitra plus 400 mg overnight delivery, usually a valgus deformity discount 400 mg levitra plus otc, which is reflected in the gaping fracture gap on the medial side (a) order levitra plus 400 mg with amex.

If the medial fracture can- not be closed by cast wedging, the fracture must be managed by closed reduction and the resulting posi- tion secured ideally with a medially fitted external fixator (c).

The imbalance between rapid 6 years of age should be corrected surgically, preferably consolidation of the lateral bending component and the towards the end of growth, in view of the high risk of delayed healing of the completely fractured tension side recurrence. If this is delayed, it may subsequently be possible to correct the deformity only by means of a double osteotomy, since the valgus position moves to the center of the shaft as growth progresses and the proximal and distal tibial joint surfaces spontaneously align themselves horizontally resulting in an S-shaped double deformity.
