š¬ What Are Growth Plates? * Location: Growth plates are areas of cartilage near the ends of long bones (e.g., femur, tibia, humerus). * Function: They are the primary sites of bone growth during childhood and adolescence. * Composition: Made of hyaline cartilage, which is gradually replaced by bone through a process called endochondral ossification. š What Do Growth Plates Do? * Control longitudinal growth of bones. * Allow bones to lengthen as children grow. * Influence overall height and limb proportions. * Contain zones of: * Resting cartilage * Proliferating cartilage (where chondrocytes divide) * Hypertrophic cartilage (where chondrocytes enlarge) * Calcification and ossification ā³ When Do Growth Plates Close? * Closure = cartilage is completely replaced by bone, forming the epiphyseal line. * Girls: Usually close between ages 12ā16 * Boys: Usually close between ages 14ā18 * Influenced by: * Sex hormones (estrogen/testosterone accelerate closure) * Genetics * Nutrition and health status ā ļø How Can Trauma or Fractures Affect Growth Plates? * Growth plates are weaker than surrounding bone, making them more prone to injury. * Salter-Harris classification describes types of growth plate fractures: * Type IāV, with increasing risk of growth disturbance * Complications from injury: * Growth arrest (partial or complete) * Limb length discrepancy (one limb grows slower or stops growing) * Angular deformities (asymmetric growth on one side of the plate) * Mechanisms: * Damage to proliferative/hypertrophic zones can halt cell division or ossification. * Formation of a physeal bar (bony bridge across the growth plate) can tether growth. š ļø Treatment of Growth Plate Injuries * Non-surgical for stable fractures (casting, close monitoring) * Surgical for: * Displaced fractures * Bar resection or correction of angular deformities * Limb lengthening procedures (e.g., epiphysiodesis or external fixation) š§ Key Takeaway: Growth plates are essential for bone growth but vulnerable to injury. Trauma during key growth years can result in lifelong skeletal issues without timely diagnosis and treatment.š¬ What Are Growth Plates? Sound Effects Free Download.
