Overuse injuries in the pediatric and adolescent athlete
1University of Missouri-Kansas City School of Medicine, USA.
Abstract:
A growing number of pediatric orthopedic patients fall into two dissimilar groups: the obese patient with problems related to obesity, and the young athlete injured during sports. While there is widespread recognition of pediatric orthopedic diseases related to obesity, the injuries resulting from "overuse" or over participation in sports are less understood and recognized. The majority of athletes involved in team sports in the Unites States are grade school and interscholastic athletes. The motivation for participation in sports varies greatly. Young athletes at risk for injury include the reluctant athlete who is not in the aerobic condition necessary to participate in sports, the eager athlete who initiates participation too vigorously, and the ambitious athlete who chronically "overtrains".

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Bones of the Lower Limb: Femur and Patella
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
