Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

20
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Traumatic Memory01:20

Traumatic Memory

769
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Post-traumatic Stress Disorder01:27

Post-traumatic Stress Disorder

974
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Cellular Injury I: Introduction01:00

Cellular Injury I: Introduction

67
Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...

Cellular Injury II: Classification01:21

Cellular Injury II: Classification

56
Cellular injury is any process that disrupts a cell’s ability to maintain homeostasis, leading to structural or functional changes. It is broadly classified based on etiology (cause) and mechanism of damage.Classification by EtiologyCellular injury may result from several causes. Hypoxic injury happens due to reduced oxygen delivery, most commonly from inadequate blood supply, such as arterial obstruction; for example, coronary artery thrombosis can cause myocardial infarction. Chemical...

Spinal Cord Injury ll: Pathophysiology01:14

Spinal Cord Injury ll: Pathophysiology

23
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

    Area of Science:

    • Orthopedic surgery
    • Pediatric orthopedics
    • Traumatology

    Background:

    • The lateral condyle of the humerus is a common fracture site in children.
    • Late or delayed union and nonunion are known complications.
    • This study focuses on fractures presenting significantly after the initial trauma.

    Discussion:

    • Late presentation suggests potential for initial misdiagnosis or subtle injury.
    • These fractures may require different surgical approaches compared to acute injuries.
    • Understanding the biomechanics of late displacement is crucial for treatment.

    Key Insights:

    • Delayed diagnosis of lateral condyle humerus fractures can lead to significant complications.
    • Surgical intervention is often necessary for malunion or nonunion.
    • Early recognition and appropriate management are vital for optimal outcomes.

    Outlook:

    • Further research into predictive factors for late fracture development is warranted.
    • Long-term follow-up studies are needed to assess functional outcomes.
    • Improved imaging techniques may aid in earlier detection.
