Certainly this condition should be considered in adolescents with back pain that is not purely mechanical in nature 60 caps diabecon with amex diabetes generic test strips, and particularly in those with episodes of recurrence and spinal stiffness. Spondylolisthesis Forward slipping of one vertebra on another (spondylolisthesis), has been recognized as a cause of back disability in adolescence for over 200 years. Spondylolysis is the term used to describe the defect in the pars interarticularis regardless of the extent of any slipping. Although there are ﬁve separate types of spondylolisthesis, the spondylolytic type is the most commonly encountered (Figure 5. The spondylolytic type of spondylolisthesis occurs in approximately two to six percent of Americans. The defect is generally recognized between four and seven years of age or older. It is generally agreed that forward slipping, if it is going to occur, will occur and progress prior to the age of 20 years and usually over a two-year period of time from the time of its presentation. Lateral radiograph demonstrating signiﬁcant L5-S1 Recent studies have indicated that repetitive spondylolisthesis. The overall incidence of spondylolisthesis is higher in gymnasts, football linemen, wrestlers, and dancers. There is no question that spondylolytic spondylolisthesis is a signiﬁcant cause of backache in children and adolescents and often of disabling proportions. Clinically the patients will present with lumbar back pain, occasionally an exaggerated lumbar lordosis in the area of slipping, and hamstring tightness. Pain is generally elicited with forward bending and pressure on the spinous processes of L4 and L5. There may or may not be neurologic Adolescence and puberty 88 ﬁndings of sciatic stretch in the lower extremities. Clinical suspicion should prompt radiographic examination to reveal the spondylolytic defect, or true spondylolisthesis. Radionucleotide imaging currently is the most desirous means of establishing a diagnosis of spondylolysis. Computed tomography (CT) scanning can be useful in further delineating the extent of the defect and in following any potential healing of the defect in those cases of “acquired” stress fracture. In general, conservative back programs are used for minimal degrees of slipping. Occasionally spinal orthotics are used and surgical stabilization or reduction of the degree of the slipping may be necessary for more severe Figure 5. The head to neckrelationship in acute slipped capital femoral degrees of spondylolisthesis or chronic epiphysis. Slipped capital femoral epiphysis Slipped capital femoral epiphysis, is a disorder of puberty characterized by slipping (movement) of the femoral head off the femoral neck. The femoral head ultimately migrates into a position of posterior–inferior displacement relative to the femoral neck.
They reported that approxi- mately one-half of children aged 0–14 with burns of 49% total body surface area (TBSA) would die buy 60 caps diabecon otc diabetes type 1 groups, 46% TBSA for patients aged 15–44, 27% TBSA for those 221 222 Wolf of age 45–64, and 10% TBSA for those 65 and older. The dramatic effect of the practice of early wound excision on burn mortality cannot be overempha- sized. This single advancement has led, in my opinion, to the routine survival of patients with massive burns in centers with experience in their care. Burn wounds can be roughly categorized into two classes: partial-thickness and full-thickness. Partial-thickness wounds will generally heal by local treatment with skin substitutes or topical antimicrobials, and therefore do not require opera- tive treatment. Full-thickness and very deep partial-thickness wounds, however, will require other treatments to affect timely wound healing. Since all the elements of the epidermis have been obliterated in full-thickness wounds, healing can occur only through wound contraction and/or spreading epithelialization from the wound edges. In a sizable wound, this process will take weeks to months to years to complete. To accelerate this process, skin grafting with the necessary keratinocytes from other parts of the body can be used. Alert patients do not generally tolerate this procedure, so anesthesia is necessary. Therefore, these procedures to accelerate burn wound closure are performed in the operating room. This chapter reviews the general principles of burn surgery, defines which patients should receive operations for burn wound closure, discusses necessary equipment and skills including patient preparation, reviews an excision and grafting proce- dure for a major burn, and discusses the techniques generally chosen based on the patient and injury characteristics. The discussion is general and therefore applicable to all specialists doing burn surgery. However, some of this information is by necessity an opinion and should be treated as such. Some local practices followed at different institutions may differ significantly from what is espoused here; however, they all should adhere to the general principles of burn surgery. GENERAL PRINCIPLES The intent of burn wound operations is twofold: to remove devitalized tissue and restore skin continuity. The Major Burn 223 The techniques used to achieve these goals are numerous; the choice of which is the challenge and art of burn surgery. Excision In concept, the first part of the operation involves removal of devitalized tissue injured in the burn. This tissue by definition does not receive blood supply and provides an excellent environment for the proliferation of micro-organisms. Therefore, no advantage exists in leaving this eschar in place on a burn wound, and it should be removed.
