Study Notes
Fractures
- Disruption in bone continuity
- Occurs when stress exceeds bone's capacity
- Fracture causes:
- Trauma (direct/indirect)
- Fatigue stress
- Pathologic stress (weakened bone)
- Diagnosis:
- X-ray
- CT scan
- Bone scan
- Treatment:
- Reduction (realignment)
- Immobilization
- Restoration of function
Bone Healing
- Hematoma formation (blood vessels of periosteum)
- Neovascularization (release of growth factors)
- Soft tissue callus (fibroblasts & osteoblasts)
- Ossification (mineral salt deposition)
- Conversion to bony callus
Classification of Fractures
- Location: proximal, midshaft, distal, etc
- Type: open/closed, degree of fragments, direction (transverse, spiral)
- Types of fractures: simple, compound
Fracture Manifestations
- Pain
- Ecchymosis (bruising)
- Swelling
- Loss of function
- Crepitus
- Abnormal mobility
- Muscle spasm
- Numbness
- Tenderness
Pathogenesis
- Hematoma formation: blood clot
- Soft callus formation: granulation tissue
- Hard callus formation: bony collar
- Remodeling: conversion to compact bone
Fat Embolism Syndrome
- Fat droplets in blood vessels (lungs, brain)
- Origin from bone marrow
- Symptoms: respiratory failure, cerebral dysfunction, petechiae
- Diagnosis: CXR, ABG
- Treatment: early stabilization, supportive care
Compartment Syndrome
- Increased pressure within muscle compartment (fascia)
- Possible causes: decreased compartment size, increased content volume
- Symptoms: severe pain, paresthesia, diminished pulse
- Treatment: emergency decompression (needle)
Fracture Complications
- Increased risk of infection (especially open fractures)
- Malunion (deformity)
- Delayed union (slow healing)
- Nonunion (failure to heal)
- Fracture blisters (skin bullae)
