In addition to the infantile form, there is a juvenile variant, which can involve the spontaneous formation of a medial bridge across the epiphyseal plate and necrosis of the proximal medial tibial epiphysis. Rickets can be related to the diet or occur as a vitamin D-resistant condition ( Chapter 4. A varus position with an intercondylar distance of more than 2 cm should be corrected, particularly if a rotational deformity is also present in the lower leg. Up until the age of 8–10 years a gap between the malleoli is apparent in most children when the knees are approximated. The persistence of genua valga beyond the age of 10 is rare and almost always caused by rela- tively pronounced overweight. Genu valgum is much less commonly associated with pre-arthritis compared to genu varum, and the need for treatment is likewise reduced and indicated only in severe forms. Recurvation of up to 10° in the knee is an expres- sion of general ligament laxity and commonly occurs in children. The cause can usually be found not just in the capsular ligament apparatus, as the physiological inclination of the tibial plateau is also missing, whether as a result of idiopathic, posttraumatic or iatrogenic factors (after ⊡ Fig. Correction surgically-induced damage to the apophysis on the tibial of the pronounced genua vara required osteotomies on the upper and tuberosity). There is a normal range for the position of these joints in respect of the mechanical and anatomical axes of the femur and/or tibia. In the frontal plane we use both the anatomical and mechanical axis lines in thera- peutic planning. Since the mechanical axis is less relevant in the sagittal plane, only the anatomical axis is used for planning. Angulation deformities are characterized by four parameters: ▬ level of the apex of the angulation, ▬ plane of the angulation, ▬ direction of the apex in the plane of angulation, ▬ extent of the angulation. In order to correct the angulation deformity, all of these parameters must be determined before the level and type of osteotomy to be performed is selected. The apex of the angulation is measured as the intersection between the proximal and distal axis lines. The extent of the angula- tion is determined at the level of the apex as a transverse angle. A line bisecting this angle is drawn through the apex, thus dividing the lon- ⊡ Fig. Treatment Conservative treatment Although numerous measures have been proposed for correcting axial and rotational deformities, none has proved completely effective to date. The list of measures starts with the instruction that the child should not be allowed to adopt a »reverse cross-legged« sitting position. In a child with increased anteversion, the hip is well centered when the legs are internally rotated. If the legs are placed in a position of external rotation, the femoral head subluxates anteriorly. For the purposes of derotation, the dynamic forces during walking are far more effective than the static forces during sitting. These extend later- ally on the leg from a hip strap to a lower leg orthosis and force the foot to twist outwards. However, the inefficiency of this rather unpleasant measure for children has since been confirmed. Nor has the treatment with diagonal inserts proved effective in influencing the anteversion. At- tempts to treat genua vara or genua valga with splints are also doomed to failure. Such splints are usually worn only at night when no dynamic forces are involved. Since the knee ligaments are elastic, the correction takes place in the joint instead of the bone. For genua valga and vara we tibial plateau recommend 3 mm medial and lateral wedges respectively, 554 4. But since it is harmless and does not bother the child we can nevertheless recommend it. Surgical treatment Correction of femoral neck anteversion If an anteversion of more than 50° is present at the age of 12 years, the possibility of surgical correction can be con- 4 sidered, particularly if the ability to rotate the hip exter- nally in the extended position is restricted to 20° or less. In unilateral cases we correct this deformity by means of an intertrochanteric osteotomy and fix the result with an angulated blade plate (⊡ Fig. If the osteotomy is performed on both sides at the same time at the intertrochanteric level, a 6-week period of bedrest would have to be expected, even with the use of modern ⊡ Fig. An alternative is to perform the osteotomy tibial derotation osteotomy for a pathological lateral torsion of the tibia at the supracondylar level above the knee and insert in a 10-year old boy low-contact plates with fixed-angle screws (⊡ Fig.

One can easily argue the opposite and note that what- ever cultural differences exist are not limited to pain or negative affect 6 discount provera 2.5 mg without a prescription menstruation reddit. ETHNOCULTURAL VARIATIONS IN PAIN 173 and that societies that openly express pain also seem to openly express joy or happiness cheap provera 10mg on line menstruation not coming. We have not clarified the definitions of race and ethnicity, often using them interchangeably. Many scholars challenge the concept of “race-as- biology,” arguing that it is, in fact, a social construct (Goodman, 2000). No genetic signature identifies individuals as members of a particular race, and even the term ethnicity leads to confusions (Dimsdale, 2000; Morris, 2001). A twin study of laboratory pain sensitivity (MacGregor, Griffiths, Baker, & Spector, 1997) found equally high correlations between both monozygotic and dizygotic twins, leading to the conclusion that “there is no significant genetic contribution to the strong correlation in pressure pain threshold that is observed in twin pairs. These findings reinforce the view that learned patterns of behavior within families are an important determinant of perceived sensitivity to pain” (p. A recent investigation by Raber and Devor (2002) showed that in rats the characteristics of a cagemate can largely override genetic predispositions to pain behavior, possibly through the influence of stress. They concluded: Can the presence of social partners affect pain behavior without actually al- tering felt pain? In animals, we have no direct access to information of pain ex- perience except as reflected in behavior. Could genotype or social convention (including the presence of specific others) change outward pain behavior without actually affecting the “raw feel” of the pain? In humans, the answer is clearly yes, although intuitively one imagines that rodents are less bound by social context (innate or learned), and that pain behavior should therefore more faithfully reflect actual pain sensation. Black, and White, and Asian groups within a single society such as the United States may have enormous differences in child-rearing practices, modeling, and behavioral reinforcement, in addition to whatever genetic factors might distinguish them. One cannot legitimately lump together individuals from China, Japan, Thailand, the Philippines, Singapore, Korea, Indonesia, and so on and pre- tend that they share a single cultural identity that can be labeled “Asian. This is not to say that there are no differences between racial or ethnic groups. Rather, it is to encourage extreme caution in statements based on 174 ROLLMAN small numbers in a single community. African Americans living in a major metropolitan area or a university town are not representative of all African Americans and are certainly not representative of all Blacks. We cannot have it both ways with regard to White participants: to proclaim the sup- posed differences between Irish, Italians, Poles, and Scandinavians, and then to randomly lump a cluster of them together as “Whites” or “Cauca- sians” when we need a group to contrast with Blacks or Asians. It is misleading and potentially detrimental to generalize to all members of one group based on a handful of subjects, often obtained nonrandomly, and who differ from other members of their group in myriad respects. The NIH Guidelines for Inclusion of Women and Minorities as Subjects in Clinical Research (http://grants1. To the extent that such research shows that there are ethnocultural dif- ferences in pain or the effects of analgesics or the degree of negative affect or the effects of psychosocial interventions, we have a responsibility to identify the evidence and take appropriate action to modify clinical prac- tice guidelines. At the moment, it seems we are best able to say that all pa- tients should be carefully evaluated and treated with respect. Irrespective of their ethnocultural status, their pain reports must be accepted and all ef- forts must be undertaken to reduce their pain and distress.
