Study Notes
Musculoskeletal System
- Comprises bones and voluntary muscles of the body.
- Functions to provide structure, support, and movement.
Skeletal Muscle
- Attached to bones via tendons, which are tough, fibrous structures.
Fractures
- Defined as a break in the continuity of the bone.
- An open fracture occurs when the overlying skin is no longer intact; bone ends may protrude through the skin.
Zone of Injury
- Refers to the area of soft-tissue damage surrounding a musculoskeletal injury.
- Important for understanding potential complications and treatment.
Deformity from Injuries
- Displaced fractures are most likely to result in visible deformities compared to other types of injuries like strains or sprains.
Crepitus and False Motion
- Indicators of a fracture; crepitus refers to a grating sensation or sound, whereas false motion indicates abnormal movement.
Life-Threatening Injuries
- A pelvic fracture with hypotension poses the greatest threat to a patient's life due to potential internal bleeding and shock.
Patient Assessment
- In case of significant injuries, such as femur fractures, first stabilize the patient's head and conduct a primary assessment.
- For penetrating injuries with bleeding, such as a gunshot wound, control bleeding and cover the wound first.
Splinting Guidelines
- Splint musculoskeletal injuries before moving the patient, unless the patient is clinically unstable.
- If a limb is deformed and moving it causes pain or resistance, splint it in the position of deformity.
Secondary Assessment
- In cases of severe trauma (e.g., falls from height) with signs of shock (low blood pressure, weak pulse), stabilize the pelvis and ensure spinal protection before transport.
