Osteoporosis is defined as a systemic skeletal disease characterized by compromised bone strength, and micro architectural deterioration of bone, leading to fragility fractures. Osteoporosis is one of the major noncommunicable illnesses. The predominance of osteoporosis and its outcomes (i.e., delicacy cracks) is expanding worldwide in corresponding with worldwide populace maturing. Osteoporotic fractures happen when a mechanical pressure applied deep down surpasses its quality. The most regular fracture areas are the vertebral body, the proximal femur, the proximal humerus, and the distal radius. Delicacy fractures are results from low-energy trauma because of mechanical powers equal to a fall from a standing stature or less, which would not normally cause a fracture. It is currently accepted that skeletal fragility requires diminished bone density and poor bone quality, characterized as modifications in bone architecture, bone geometry, and the material properties of the micro structural constituents, for example, collagen and mineral, just as the nearness of micro damage.

Once thought to be a unique health problem in older adults, osteoporosis has now been recognized as a condition also seen in pediatric patients. Awareness among pediatricians is fundamental to recognize patients in danger of creating osteoporosis. Past fractures and spinal pains are clinical indicators, and low cortical thickness and low bone density are radiological indicators of fractures. Osteogenesis Imperfecta (OI) is an uncommon disease and should be managed in tertiary pediatric units with the essential multidisciplinary ability. Current OI the executives centers on practical results as opposed to simply improving bone mineral thickness. While treatment for OI has improved immensely in the course of the most recent couple of decades, this ceaseless hereditary condition has some inescapable, inadequately treatable and impairing inconveniences. Vertebral fractures may bring about scoliosis or kyphosis and, in light of the fact that they might be clinically silent; it is basic that vertebral fractures are analyzed in children precisely and at an early stage, so the important clinical consideration can be executed.

Osteoporosis in children has a broad range of etiologies, and is classified into 2 groups: primary osteoporosis or genetic bone disease, and secondary osteoporosis due to underlying chronic diseases. In affected children, further debilitating of bone ought to be kept away from by limiting exposure to osteotoxic medicine and advancing nourishment including calcium and vitamin D. The diagnosis of osteoporosis in children should not be made on the basis of densitometric criteria alone. The presence of bone fragility with a history of clinically significant fractures and significantly low bone density are required for diagnosis of pediatric osteoporosis. Vertebral fracture in the absence of high energy trauma or local disease is pathognomonic for osteoporosis and can allow the diagnosis without detection of significantly low bone density. Traditionally, diagnosis of osteoporotic vertebral fractures has been from sidelong spine radiographs; in any case, few investigations have indicated that double energy x-beam absorptiometry is tantamount to radiographs for recognizing vertebral fractures in youngsters, while permitting less radiation introduction. The finding of vertebral fractures from double energy x-beam absorptiometry is named vertebral fracture evaluation. Existing scoring frameworks for vertebral break evaluation in grown-ups have been surveyed for use in kids, yet there is no standardization and observer dependability is variable.

Monitoring for bone health should include screening for vertebral fractures that are common and often asymptomatic in children with risk factors for osteoporosis. Other diagnostic studies include biochemical markers of bone turnover, bone mineral density by dual-energy x-ray absorptiometry, as well as spinal imaging using densitometry lateral spinal imaging. Existing scoring frameworks for vertebral fracture assessment in adults have been surveyed for use in children, yet there is no standardization and observer reliability is variable. This writing survey recommends the requirement for a semi-automated instrument that will permit increasingly dependable and exact discovery of vertebral breaks in children. Optimizing bone health in children with osteoporosis includes treating the underlying condition causing bone fragility, and ensuring adequate weight-bearing exercise, vitamin D and calcium intake. Pharmacologic agents should be offered to patients with fragility fractures. Bisphosphonates have been used successfully in pediatric patients. This lecture reviews the latest advances in the assessment and treatment of pediatric osteoporosis.
