After the connection was finally con- firmed in 1961, the incidence retuned to its previous level. Classification In the middle of the 19th century Saint-Hilaire in- troduced Greek terms to describe various malformations. Thus an »amelia« referred to the absence of an extremity (Greek: melos = limb). Other terms included »hemime- lia« (Greek: half limb), »phocomelia« (Greek: seal limb) and »ectromelia« (Greek: ectros = absence). Since this term ectromelia has been used to describe a wide variety of malformations it has proved unsuitable as a precise description. The first useful systematic classification was proposed by Frantz and O’Rahilly in 1961. This classification formed the basis for the current classification, which has been modified and adopted by various international associations, including the »National Academy of Sci- 465 3 3.

It is assumed that by the age of 18 a person has reached such a level of maturity as to be capable of making fully informed decisions generic 60caps diabecon. However generic diabecon 60 caps with visa, it is the process of growth and development during childhood and adolescence that results in maturity and not chronological age alone. Growth is the progressive development of a living being, or any part of it, from its earliest stage to maturity1. In health care we usually restrict the term to mean the physiological and anatomical changes that occur. Different parts of the human body grow at different rates and the growth of one system can be affected by the activity of another (e. In contrast, the term development is commonly used to describe the psychological and cognitive advancement of a child and the acquisition of motor and sensory skills. Growth and development are variables of childhood and children of the same age can be at different growth and developmental stages. Consequently, when deciding the most appropriate health care approach it is important to allow for a child’s individuality and to avoid making assumptions about a child based upon preconceived ideas pertaining to specific chronological ages. However, although children of the same age can be at different developmental stages, the order in which growth and development occurs is generally consistent for all 2 children. For example, ossification of the carpus occurs in the same order for all children, but the exact age at which the carpal bones ossify can vary markedly. As a result of predictable developmental staging, many texts, including this one, have provided general growth and development charts that are loosely linked to chronological age. These charts are not definitive and radiographers should not rely upon them solely but should combine them with a general understanding of the child development process. Appreciating the social, physical and cognitive developments that occur during these phases of childhood will assist the radiographer in selecting a suitable approach to the examination and will ensure appropriate and effective patient communication and co-operation. Physical growth The peculiarity of growth is what physically differentiates a child from an adult. Infants grow rapidly in the first year of life, increasing their body length by approximately 50%. Between 1 and 2 years of age, a child’s height increases by approximately 12cm and thereafter, until puberty, children increase in height by approximately 6cm per annum. The onset of puberty is associated with a sudden and marked increase in growth (the adolescence spurt) and this phase lasts for approximately 2 to 3 years in both boys and girls. Each organ or system grows at a different rate and therefore the relationship between one part of a growing body and another changes over time3. It is important to note that at birth the head and upper body are larger and functionally more advanced than the lower body. As the child grows, a leaner shape with longer legs is gradually adopted and the relative size of the upper body and head decreases. The rate at which growth occurs varies between children and is also inconsis- tent within an individual child. Growth is episodic rather than constant and Understanding childhood 3 Age 5 Years Physical Growth spurt development Hops, skips, rides bike Start of puberty – girls Growth spurt Basic writing skills Improving pencil Start of puberty – boys manipulation Cognitive Understands Ability to reason logically development conservation of number Increasing ability to reason logically Increasing capacity to remember Social/emotional development Prefers friendships of own gender Adult identity develops Understands Self-esteem decreases concept of trust Peer approval important Increasing value of self-worth Fig. The natural cyclic nature of growth can be adversely affected by serious childhood illness, resulting in decreased growth, and in some children noticeable growth retardation, but upon recovery these children will usually experience a period of accelerated growth until their ‘normal’ height has been achieved. The causes and reasons for episodic rather than constant growth are not yet understood and research in this area continues. However, it appears that each child carries an internal ‘blue print’ that deter- mines their correct growth/height at a particular age and this is likely to be linked to hereditary and environmental factors. Psychological and cognitive development A variety of child development theories have been proposed but, since the 1960s, education theory of child development in the UK has been dominated by Piaget’s cognitive development theory. Piaget believed that the development of cognitive ability (acquisition of knowledge including perception, intuition and reasoning) occurred in sequential stages and he linked these to the chronological age of a child rather than to the intellectual or emotional maturity of the child as favoured by modern theorists. Cognitive development, like physical growth, is individual to the child and their personal experiences. However, a child’s level of cognition directly influ- ences their understanding of, and reaction to, illness4 and there is considerable evidence that a child’s interpretation of health and illness progresses systemati- 5 cally.

Limping secondary to abuse must always be a part of the differential diagnosis generic diabecon 60 caps with visa, particularly in this age group diabecon 60caps otc. Conditions such as toxic synovitis of the hip or knee, and juvenile rheumatoid arthritis are seen, but are far less common. Limping from a neuromuscular origin occurs not uncommonly in this age group, particularly in Figure 6. A painful foot limp with trunk shifting away from the involved the form of spastic hemiplegia. Between the ages of 3–10 years, trauma is still the most common cause for limp. Antalgic limps of hip origin are most often seen with “toxic” or “transient” synovitis of the hip and Legg–Calve–Perthes disease, which is far less´ common than “toxic” synovitis of the hip. Juvenile rheumatoid arthritis is seen in this age group, as well as osteomyelitis and occasionally septic arthritis. Between the ages of 10 years and skeletal maturity, trauma is still the number one etiology for antalgic limps. In this age group the pain syndromes of adolescence, which are adequately addressed elsewhere in the text, occupy a large proportion of the causes of limp. Slipped capital femoral epiphysis should always be primarily considered in an antalgic limp in this age group. Although other conditions are somewhat uncommon, back Miscellaneous disorders 118 pain may radiate into the lower extremities Pearl 6.

An additional method of limb length determination is performed by placing a measuring device (tape measure) at the anterior superior iliac spine and measuring the 119 Leg length discrepancy length down to the medial most distal extremity of the medial malleolus (Figure 6. An appropriate site at the maximum prominence of the medial femoral condyle may also be used to help determine the relative differential length between both femurs and both tibiae. Commonly, radiographic scanograms are taken of the lower extremities, which are quite helpful in differentiating relative disproportion between both femurs and both tibiae, but fail to include the pelvis and remaining ankle and foot below the lower end of the tibia. There are numerous disorders and diseases that may cause a lower limb length inequality. Most fall under the general categories of developmental malformations, tumors or tumor-like conditions, infections of bone and joints, trauma, neuromuscular disorders, and miscellaneous acquired conditions. They are often segregated into two basic categories: those that tend to diminish longitudinal growth, and those that tend to stimulate longitudinal growth (Pearls 6.
