Gibson National Ageing Research Institute, Parkville, and Department of Medicine, University of Melbourne Christine T. Chambers Department of Pediatrics, University of British Columbia, and Centre for Community Child Health Research, Vancouver Pain is a complex phenomenon that consists of interacting biological, psy- chological, and social components (Merskey & Bogduk, 1994). For many years, the study of pain was focused primarily on young and middle-aged adult populations; however, as research in the area of pain expanded, so did consideration of the importance of developmental factors in pain expe- rience and expression, including pain in infants, children, and seniors. Life- span developmental psychology involves the study of constancy and change in behavior through the life course (Baltes, 1987). This approach can be helpful in gaining knowledge about the pain experience across the life span and furthering understanding about interindividual differences and similarity in pain responses. The present chapter provides a broad overview of developmental per- spectives in pain across various life stages, including infancy, childhood, adolescence, adulthood, and seniors. Research pertaining to age differ- ences in pain experience and report and psychosocial and physiological factors that impact on pain for each of these developmental periods are re- viewed. Further, developmental factors that relate to pain assessment and management are discussed. An appreciation of the unique challenges faced by individuals at various stages of life is critical to furthering understanding about the developmental progression of pain across the life span. This period is charac- terized by dramatic changes to the body and brain and the emergence of a wide array of cognitive capacities, including language and the ca- pability to engage in social relationships with others. These years are character- ized by further refinements in motor skills and cognitive functioning. Advances in understanding of the self and others are evident during this phase. Cognitive abilities become more ab- stract and puberty leads to physical and sexual maturity. A broad spectrum of pain experiences is evident across these developmen- tal periods. Throughout the sections that follow, the terms children or child- hood are used to refer to the entire range from 0 to 18 years and particular developmental periods are specified as appropriate. Age Differences in Pain Experience and Report During Childhood In comparison to the extensive literature among adult populations, little is known about the epidemiology of pain in children and adolescents (Good- man & McGrath, 1991). Investigations of pain prevalence have traditionally focused on specific pain conditions restricted to particular developmental periods, rather than providing a more comprehensive description of pain problems across childhood.

Various surgical treatments have been proposed [2, 9, 10]: lengthening of the hamstring muscles, division of the shortened, dorsal soft tissue structures, epiphysiodesis of the anterior part of the distal femoral epiphyseal plate and a femoral or tibial extension osteotomy. While soft tissue operations cannot achieve any lasting effect in cases of severe contractures (particularly in arthrogryposis), ex- tending osteotomies are effective, albeit at the expense of a permanent alteration in joint anatomy. Since 1989 we have therefore used the Ilizarov ap- paratus to correct severe knee contractures. At that time, this apparatus was already being used successfully for the correction of complex foot deformities [4, 6, 7]. The method involves the fitting of 2 circular rings to both the upper and lower leg, the linking of these ring systems with 2 lateral hinged joints and a dorsal distraction rod and a ventral compression rod (⊡ Fig. Fifty percent of the patients were suffering from arthrogryposis (⊡ Fig. The flexion contracture was improved, on average, from 40° preoperatively to 6° postoperatively, ⊡ Fig. Legs of a 16-year old girl with arthrogryposis and fitted although a subsequent deterioration to 18° was noted at Ilizarov apparatus on both sides for the correction of knee contrac- the follow-up control after 3 years. Specific problems associated with the treatment of con- tractures in spastic cerebral palsies and flaccid paralyses are discussed in chapter 3.

The result is ide- ally stabilized with an external fixator, since the proximal fragment is usually too short for stable anchorage with a plate. Normally the deformity occurs on both sides and is in- herited as an autosomal-dominant condition. Clinical examination reveals a fixed flexion contracture of the affected joint: A passive and active extension deficit is present. This can be observed when the metacarpopha- langeal joint is in both the extended and flexed positions. On the x-ray there is recurvation of the distal end of the proximal phalanx, while the joint head is deformed and angulated towards the palm. Although the flexion contracture can be surgically corrected by an extending osteotomy or an arthrolysis procedure, it has been clearly shown that the b range of motion is not thereby improved. The 4th/5th digits on the right have already little finger can also prove troublesome. Syndactylies on adjacent fingers should never be separated Clinodactyly during the same operation as this would jeopardize the circulation Clinodactyly involves a deviation of the finger in the fron- tal, i. While the little finger is usually affected, a triphalangeal thumb is also often present. If pronounced angulation is present the condition is described as a delta phalanx. This is the result of abnormal epiphyses, which are rotated around the metaphysis in a C-shape, and is clearly visible on an x-ray. In the event of marked deviation, an osteotomy can restore the normal anatomical configuration. Tendovaginitis stenosans (»trigger finger«) Tendovaginitis stenosans almost always affects the thumb and involves a narrowing of the tendon sheath (or pulley) of the flexor pollicis muscle. This produces thickening of the tendon, which can only be drawn through the pulley after overcoming a certain resistance. Weakness or hypoplasia of the extensor pollicis muscle is also fre- quently present however. A flexion contracture of the metacarpophalangeal joint is also occasionally observed. The condition can be left untreated during the 1st year of life since 30% of the contractures resolve spontaneously. Radioulnar synostosis in severe pronation in a 6-year old In the other cases, simple surgical opening of the pulley boy (annular ligament release) will suffice.
