Fractures: Bone Repair01:27

Fractures: Bone Repair

5.8K
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...

Spinal Cord Injury ll: Pathophysiology

25
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...

Secondary Spinal Cord Injury llI: Pathophysiology

52
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

    Summary
    This summary is machine-generated.

    Monteggia-like lesions are forearm injuries involving ulnar fractures and radial head dislocation. Proper diagnosis and surgical fixation are crucial to prevent long-term complications like restricted movement and pain.

    Area of Science:

    • Orthopedic Surgery
    • Traumatology
    • Radiology

    Context:

    • Monteggia-like lesions are complex forearm injuries.
    • These injuries involve proximal ulnar fractures and radial head dislocation.
    • Untreated lesions risk permanent damage, including restricted motion, osteoarthritis, and pain.

    Purpose:

    • To outline the diagnostic and treatment standards for Monteggia-like lesions.
    • To emphasize the importance of accurate preoperative planning.
    • To detail the preferred surgical management strategies.

    Summary:

    • Monteggia-like lesions require prompt and accurate diagnosis, with CT imaging and 3D reconstruction as the gold standard.
    • Anatomical reduction and osteosynthesis, typically via a dorsal approach using plate fixation, is the treatment of choice.
    • Associated radial head/coronoid fractures and ligamentous injuries necessitate specific attention during treatment.

    Impact:

    • Adequate diagnosis and treatment are essential for optimal postoperative outcomes.
    • Effective management can prevent persistent morbidity such as joint stiffness and chronic pain.
    • This approach aims to restore forearm function and minimize the risk of degenerative joint disease.
