The figures marked on the template also allow an estimate to be made of the angles between the center of the femo- ral head and the anterior and posterior acetabular rims. The two angles for the anterior and posterior sides are read off the template and then marked on the x-ray. The acetabular orientation in both the sagittal and anatomical planes can be determined by drawing a line between the two marks entered for the angles on the ventral and dorsal sides. The template can also be used to calculate the relevant loading of the hip. Example of a contact area calculation using a template placed on an AP x-ray of the hip.

In a triple osteotomy, all three bones (ilium, pubis and ischium) are divided, while the cut in a periacetabular osteotomy goes around the acetabulum (and thus through the triadiate cartilagetriradiate cartilage, as well). The acetabulum is not actually enlarged but is rather rotated laterally and – if necessary – anteriorly, thereby enlarging the relevant ⊡ Fig. CT with three-dimensional reconstruction in a 15-year loading area at the cost of the caudal sections.

In contrast to developmental femoral anteversion generic betapace 40 mg visa blood pressure headache symptoms, it presents much earlier order betapace 40 mg fast delivery hypertension zebrafish, commonly seen initially between three months and two years of age. Nearly as many cases present for diagnosis and treatment prior to walking age as ever Lower extremity developmental attitudes 16 appear thereafter. The child presents to the physician initially with limbs that are “inturned. There is an inward medial rotation of the ankle and foot relative to the proximal (tibial and ﬁbular) position of the leg. On examination, the maximum prominence of the tibial tubercle is discerned, and the maximal prominence of the medial and lateral malleoli is determined. The degree of internal tibial torsion is measured as the degree of clinical rotation inwards of the “dorsiﬂexed” foot as it relates to the tibial tubercle (Figures 2. Other techniques of measurement include radiographs and the use of specialized calipers. Unfortunately, all methods fall prey to inherent variability in Figure 2.

Drawing of internal tibial torsion as viewed from proximal to age group presenting for examination. The natural benign evolution of this condition is undoubtedly the single most important piece of information to be retained. It is virtually never encountered in adolescents and teenagers unless associated with pathologic conditions. The large numbers of very young children seen with this condition, and the near total absence of teenagers, suggest that spontaneous recovery routinely occurs. There is substantial clinical scientiﬁc evidence to support the fact that spontaneous resolution occurs, and likely occurs as a compensation both through the ankle and foot, and probably through the hip and knee as well. Developmental femoral anteversion (“hip in-toeing”) The most common cause of in-toeing seen in children is developmental femoral anteversion, or more appropriately, “hip in-toeing. Patients are generally brought to the examining physician by the parents who are concerned that the child “toes in” during gait, walks “pigeon toed”, or is constantly tripping or stumbling. Most commonly, the symptoms are magniﬁed by running, tiredness, or commonly encountered when the patient is not fully conscious of the in-toeing. The maximum incidence of presentation is between two and eight years of age. Both sexes are affected equally and the clinical ﬁndings essentially mirror the symptomatology. On examination, the hips characteristically will have a great deal of internal rotation, both with the hips extended and ﬂexed, commonly approaching 90 degrees (Figure 2. External rotation in both ﬂexion and extension of the hip may range from 15–20 degrees, all the way Figure 2. Providing considerable range of internal rotation is routinely present in the clinical the child is in no way neurologically condition of developmental femoral anteversion (hip in-toeing). In all probability, the increased range of motion of the hip is a function of the very young child, whose joint ranges of motion, in general, far exceed that which will be present at the time of skeletal maturity. Laymen have Lower extremity developmental attitudes 18 always been aware that we become “stiffer” in our joints with age and it is clearly supported in the decreasing range of hip motion normally seen from birth to puberty. Inasmuch as the child has a very wide range of motion, particularly in internal rotation, it is quite comfortable for them to sit in a “W” position or a reverse “tailor” position (Figure 2. It is also more comfortable for them to walk internally rotated during gait, particularly when they are tired or running. Personal experience, using computed tomography scanning, does not support any increase in the bending of the upper end of the bony femur in relationship to the acetabulum (anteversion), an anatomic event erroneously attributed to the etiology. It is paradoxical that at birth, when true bony anteversion is at the greatest degree in the human, the range of external rotation of the hip is the greatest, as it will be throughout the ﬁrst year of life.

It is a techni- our experience, this operation, if appropriately indicated, cally difficult but rewarding operation. Correction of a rotational defect on the femur and tibia A major rotational defect of the femur (increased antever- sion) or tibia (increased external rotation) can represent an important (co-)factor in the dislocation process. If a relevant rotational defect is present, the correction should be performed as close to the knee as possible. This proce- dure may be performed on the tibia only after growth is concluded. The surgical treatment of the various forms of dis- location of the patella is difficult. The surgeon must be very cautious in deciding whether an operation is indicated, and the appropriate procedure must be se- lected after a discriminating analysis of all the factors. All operations are associated with recurrence rates of varying degree, and the patient and his parents must be informed of these. The surgeon should beware of pro- ceeding with excessively complicated multiple operations after the disappointment of a recurrence. The circulation in the patella is a critical parameter, and the division of vessels and scar formation on ⊡ Fig. Principle of the Insall operation: The (excessively proxi- mal) vastus medialis muscle is reanchored to the patella in a more several sides of the patella are only tolerated to a distal and lateral position.

Acticoat can be used in a similar fashion order betapace 40mg free shipping blood pressure 5640, although it does not allow for good hygiene and is more difficult to care for generic 40mg betapace with mastercard blood pressure medication polygraph. Porcine xenograft can be used as donor sites dressing, although it is not the standard of care. Skin grafts are generally dressed with protective bandages that provide good environmental properties to expedite vascular inosculation. It is necessary to place hands, feet, and joints in good functional position to allow graft take in maximum range of motion. Splinting may be necessary; therefore good communication with rehabilitation services is a must. Following graft fixation, a petrolatum-impregnated fine mesh gauze is placed in direct contact with the graft, and a soft dressing with soft The Small Burn 219 gauze, Kerlix (if limbs are involved), and compressive bandages are applied. Excessive pressure should not be applied in order to avoid postoperative hemato- mas due to excessive venous pressure and the development of compartment syn- drome. It does not stick to the wound, and removal of dressing is easy with minimal pain. The main purpose of all dressings is to provide protection and immobiliza- tion of the graft site. When grafts are in close vicinity to superficial burns and donor sites, Biobrane should be considered. It allows for satisfactory wound healing for both grafts and superficial wounds. Biobrane is secured in place as described for superficial wounds, including the graft site in the dressing. In cooperative patients and on special locations (face, hands) grafts can be left exposed. Antimicrobial creams (bacitracin or polysporin) should be applied on the surface of the grafts to prevent contamination of graft seams and graft desicca- tion. If the exposed method is used in hand grafts, the ukulele splint should be considered to allow full range of motion and good graft positioning. When all dressings have been applied, the anatomical location should be elevated and protected. Postoperative instructions are given to the nursing staff and on call team, and the patient and relatives are informed of the postoperative wound care plan. Grafts are inspected 5–7 days after surgery unless the clinical picture of the patient dictates otherwise. INTRODUCTION Over 1 million people are burned in the United States every year, most of which injuries are minor and treated on an outpatient basis. Almost all of these treated as outpatients do not require operative treatment. However, approximately 60,000 burns per year are more severe and require hospitalization, and roughly 3000 of these patients die. Between 1971 and 1991, burn deaths in the United States decreased by 40%, with a concomitant 12% decrease in deaths associated with inhalation in- jury. These im- provements were probably due to prevention strategies resulting in fewer burns of lesser severity, as well as significant progress in treatment techniques. Improved patient care in the severely burned, including operative strategy and techniques, has undoubtedly improved survival, particularly in children. Bull and Fisher first reported in 1952 the expected 50% mortality rate for burn sizes in several age groups based upon data from their unit. They reported that approxi- mately one-half of children aged 0–14 with burns of 49% total body surface area (TBSA) would die, 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.
