Study Notes
Fractures and Dislocations
- Fractures are complete or incomplete disruptions in the continuity of bone structure, occurring when the bone is subjected to stress greater than it can absorb.
- Causes of fractures: direct blows, crushing forces, sudden twisting motions, and extreme muscle contractions.
Types of Fractures
- ' Closed Fractures (simple fractures): do not cause a break in skin.
- Open Fractures (compound/complex fractures): skin or mucous membrane wound extends to the fractured bone.
Specific Types of Fractures
- Transverse fractures
- Short oblique fractures
- Long oblique fractures
- Spiral fractures
- Segmental fractures
Clinical Manifestations of Fractures
- Pain: continuous and increases in severity until fragments are immobilized.
- Loss of function: fractured extremity cannot function properly.
- Deformity: detectable when compared to non-injured extremity.
- Shortening: commonly seen in long bone fractures.
- Crepitus: crumbling sensation/sound produced by a fractured extremity upon gentle palpation.
- Localized edema and ecchymosis: occurs as a result of trauma and bleeding into the tissues.
Diagnosis of Fractures
- X-ray: confirms the presence of a fracture.
Emergency Management of Fractures
- Immobilize injured extremity before moving patient.
- Splinting the injured part.
- If open fracture: cover wound with sterile dressing to prevent contamination of deeper tissues.
- Apply splint for immobilization.
Medical-Surgical Management of Fractures
- Reduction: restoration of the fracture fragments to anatomic alignment and positioning.
- Immobilization: holding the bone fragments in position until solid bone healing occurs.
- Maintaining and restoring function: through exercises and rehabilitation.
Joint Dislocation
- Subluxation: a partial dislocation that does not cause as much deformity as a complete dislocation.
- Clinical manifestations: acute pain, change in or awkward positioning of joint, and decreased ROM.
- Medical management: immobilize affected joint, closed reduction, and gentle, progressive exercises to preserve ROM and restore strength.
Open Reduction Internal Fixation (ORIF)
- Through a surgical approach, the fracture fragments are anatomically aligned.
- Internal fixation devices (metallic pins, wires, screws, plates, nails, or rods) are used to hold the bone fragments in position until solid bone healing occurs.
This quiz covers the medical-surgical management of fractures, including closed reduction and stabilization techniques. It discusses the importance of prompt intervention to prevent complications and promote healing.
