Study Notes

Skeletal Trauma

Skeletal trauma encompasses various disorders, including trauma, infections, neoplasms, and childhood disorders.
Fractures are a common form of skeletal trauma.
Fractures are characterized by discontinuity of bone.
Common fracture locations in younger individuals include the hands, clavicles, and humerus.
Proximal femur, pelvis, and vertebrae are common fracture sites in older adults.

Fracture Classification

Fractures are classified based on various characteristics, including:
Type:
- Simple: Involves two segments.
- Complex: Involves more than two segments.
- Open (Compound): Skin is disrupted.
- Closed (Simple): Skin is intact.
- Comminuted: Multiple fragments.
- Greenstick: Incomplete fracture, mostly in children.
- Oblique: At an angle.
- Transverse: Perpendicular to the bone's longitudinal axis.
- Spiral: In a spiral fashion.
- Longitudinal: Along the length of the bone.
- Impacted: Fragment driven into the bone medulla.
Location:
- Epiphyseal: At bone ends (proximal, distal).
- Diaphyseal: At the bone's shaft.
- Intertrochanteric: Specific to the proximal femur.
- Malleolar: Involves ankle bones
Stability:
- Stable: Not movable.
- Unstable: Movable.
- Impacted: Fragment driven into the bone medulla.
- Linear: Hairline fracture (minimal disruption).
- Depressed: Bone fragments driven inward (usually skull fractures).
Geometry:
- Transverse: Perpendicular to the bone's longitudinal axis.
- Oblique: At an angle.
- Spiral: In a spiral fashion.
- Longitudinal: Along the length of the bone.

Trauma to Joints

Joint injuries include sprains, dislocations, subluxations, and separations.
Sprain:
- Grade I: Mild stretching of ligaments.
- Grade II: Partial tear of ligaments.
- Grade III: Complete tear of ligaments with instability.
Dislocation:
- Displacement of bone ends at a joint.
- Joint capsule and ligaments tear when dislocated.
Subluxation:
- Partial dislocation of a joint.
Separation:
- Dislocation at a cartilaginous joint.

Complications of Fractures

Soft tissue (muscle, nerve, CNS) injuries are common.
Hemorrhage: Blood loss at the injury site.
Infection: Can complicate fracture healing.
Fat embolism: Dislodged fat from marrow leads to pulmonary complications.
Deformity: Uneven or misaligned bone resulting from the injury.

Signs and Symptoms of Fractures

Pain
Impaired sensation
Decreased mobility
Muscle spasm
Deformity
Swelling
Loss of function
Crepitus (grating sound or sensation).

Treatment of Fractures

Closed Reduction: Manipulation and repositioning of bone fragments.
Open Reduction: Surgical procedure to fix the fracture.
Internal fixation: Surgical insertion of plates, screws, rods to stabilize the fracture.
External fixation: External bars and pins to stabilize a fracture.

Tendonitis and Bursitis

Tendonitis: Inflammation of tendons, causing flexibility loss, pain and scarring from overuse.
Bursitis: Inflammation of bursae, protective fluid-filled sacs, common in the shoulder, elbow, hip, knee.
Causes: Systemic diseases (rheumatoid arthritis), chronic friction / trauma, crystal deposition, infection.
Diagnosis: Medical history, physical exam, X-rays (to rule out bone abnormalities), MRIs (to detect tendinitis), screening tests (CBC, rheumatoid factor).
Prevention: Eliminate provoking factors, proper conditioning, gradual activity introduction, warm-up/stretching, and proper gear.
Treatment: Lidocaine/steroid injections, analgesics + exercise, NSAIDs, acupuncture, physical therapy (PT), occupational therapy (OT).
