Bone Disorders01:29

Bone Disorders

3.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

928
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
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...

Disorders of the Urinary System

279
The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.4K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Fractures: Bone Repair01:27

Fractures: Bone Repair

3.2K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
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...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

155
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

    Area of Science:

    • Pediatric Orthopedics
    • Radiology
    • Pediatric Rheumatology

    Context:

    • Hip joint abnormalities are common in infants and children, requiring accurate diagnosis for effective management.
    • Conditions range from developmental dysplasia of the hip to avascular and inflammatory processes.
    • Distinguishing between various hip pathologies is crucial for appropriate treatment and prognosis.

    Purpose:

    • To review and illustrate the typical imaging findings for several pediatric hip conditions.
    • To provide guidance on differentiating between similar-presenting hip pathologies in children.
    • To emphasize the role of imaging in the early detection and management of pediatric hip disorders.

    Summary:

    • Developmental dysplasia of the hip involves acetabular dysplasia and hip instability, diagnosed via ultrasound.
    • Legg-Calvé-Perthes disease presents with avascular necrosis of the femoral head in childhood.
    • Slipped capital femoral epiphysis involves adolescent femoral head displacement; synovitis, osteomyelitis, Langerhans cell histiocytosis, and neuroblastoma also present with hip pain and require specific imaging evaluation.

    Impact:

    • Improved diagnostic accuracy for pediatric hip conditions through understanding imaging characteristics.
    • Facilitation of timely and appropriate treatment by differentiating between various hip pathologies.
    • Enhanced clinical decision-making for pediatricians and radiologists managing hip disorders in children.
