Cardiovascular System Abnormal Findings I: Inspection and Palpation01:29

Cardiovascular System Abnormal Findings I: Inspection and Palpation

240
In a cardiovascular examination, inspection and palpation are crucial for identifying abnormalities.

Assessment of the Cardiovascular System III: Palpation

174
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.1K
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...

Bones of the Lower Limb: Tibia and Fibula

2.6K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Bone Disorders01:29

Bone Disorders

3.4K
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...

Summary
This summary is machine-generated.

Most childhood lower extremity variations like intoeing and out-toeing are normal and resolve naturally. Reassurance and observation are key, with specialist referral only for pain or significant functional issues.

Area of Science:

  • Pediatrics
  • Orthopedics
  • Developmental Biology

Background:

  • Rotational and angular variations of lower extremities are common in children.
  • Parental concern over appearance drives many primary care visits.
  • Variations include intoeing, out-toeing, and angular deformities.

Purpose of the Study:

  • To guide primary care providers in evaluating common pediatric lower extremity variations.
  • To differentiate normal variations from true deformities.
  • To inform management strategies and parental reassurance.

Main Methods:

  • Comprehensive patient history including onset, progression, and relevant medical history.
  • Focused physical examination with specific measurements (e.g., foot progression angle, hip rotation).
  • Assessment of age-related normal ranges and functional impact.

Main Results:

  • Most variations are benign and resolve spontaneously without intervention.
  • History and focused examination are crucial for diagnosis.
  • Orthotics and braces have minimal supporting evidence.

Conclusions:

  • Many common lower extremity variations in children are normal developmental variants.
  • Reassurance and conservative management are appropriate for asymptomatic children within normal ranges.
  • Referral to pediatric orthopedics is indicated for significant deviations, pain, or functional impairment.
