PCT - Fractures

Axial Skeleton: Comprises the bones of the skull, vertebral column, and rib cage.
Tentorium: A band of tissue below the brain that can cause lacerations during head injuries if the brain moves down onto it.
- Symptoms of head injury can occur without visible bruising, swelling, or lacerations.

Shoulder Dislocations: Primarily anterior dislocations where the proximal end of the humerus rotates forward and separates from the glenoid.
Acromioclavicular Dislocation: A common injury where the collarbone (clavicle) is separated from the acromion of the scapula.
- Common mechanism: Fall forward onto an outstretched arm (e.g., diving into second base in baseball).

Carpals: Refers to the wrist bones including phalanges and metacarpals; important in assessing wrist injuries.
Pelvic Anatomy:
- Contains the ischial tuberosity, a curved part of the ischium bone.
- The anatomy of the pelvis is critical due to the presence of large blood vessels (femoral arteries and veins).
- Fractures can lead to sharp bone edges lacerating surrounding tissues, resulting in internal bleeding, which is often not externally visible.

Neck of Femur Fractures: Also known as hip fractures; the area between the femur's head and trochanters is prone to these types of fractures.
- Different from mid-shaft fractures, they present distinct clinical variations.
Joint Injuries:
- Often involve tearing of soft tissue (ligaments), leading to dislocations characterized by loss of range of motion.
- Healing may require physiotherapy to restore stability due to stretched ligaments.

The elbow joint is at significant risk for vascular and nerve compromise due to the tight anatomical space it occupies.
- Compression from either anatomical repositioning of bones (dislocation or fracture) or swelling can lead to nerve and blood vessel damage.

Blunt Traumas vs. Penetrating Traumas:
- Blunt trauma involves injuries without penetration into the body, while penetrating trauma involves any injury that breaches the skin (e.g., stabbings, gunshots).
Trauma in Different Age Groups: All age groups can experience trauma, including children, whose injuries may be due to both accidents and maltreatment.

Transverse Fracture: A simple lateral break in a bone.
Oblique Fracture: A fracture that occurs at an angle to the bone's axis.
Spiral Fracture: Caused by a twisting motion, often seen in cases of child abuse.
Comminuted Fracture: Characterized by multiple fragments or crumbling of the bone.
Avulsion Fracture: Involves a fragment of bone being separated from the main bone mass.
Greenstick Fracture: An incomplete fracture, common in children, where the bone bends and partially breaks but does not fracture completely.
Compression Fracture: A collapse of the vertebral body, often occurring without significant intervention since they typically do not require treatment.

Identification and understanding of these fractures and injuries are crucial for appropriate diagnosis and treatment.
Emergency care should address multiple injuries concerning fractures, since they can often occur in conjunction.
Surgical interventions, particularly for open fractures, often necessitate deep cleaning to prevent infection due to contamination.
Risk of Infection with Open Fractures: Surgeons manage open fractures with a focus on preventing deep tissue infections, which are more complicated to treat than superficial ones.
