Study Notes
Patterns of Fractures
- Spiral fractures: occur when bone breaks in a spiral manner, usually due to twisting movements.
- Comminuted fractures: lead to more than 2 fragments, often resulting from big trauma or RTA.
- Compression fractures: occur mostly in vertebrae due to pathological weakness (osteoporosis, bone marrow cancer, etc.).
- Green stick fracture: occurs in children (before age 10), where the bone is still slightly springy and trauma causes bending and partial fracture.
Clinical Features
- Symptoms: Pain, Swelling, Deformity, Inability to use the affected part.
- Examination: Look for deformity, swelling, and shortening. Feel for tenderness. Move to check for abnormal mobility and crepitus.
Management
- Open fracture requires more care than closed fracture.
- Transverse fracture may be easy to reduce, while comminuted fracture may need surgery.
- Immobilization is crucial to give the body time to rebuild tissue.
- Do not use the abduction bar on the cast to lift or carry the child.
- Use a diaper or sanitary napkin around the genital area to prevent leakage or splashing of urine.
Complications of Cast
- Compartment syndrome: tight cast that restricts swelling.
- Impaired distal neurovascular function.
- Deep venous thrombosis leading to pulmonary embolism.
- Re-displacement of fracture.
- Stiff joints, muscle wasting.
- Plaster sores.
- Malunion, nonunion, delayed union.
Rehabilitation
- Physical therapy during immobilization aims to:
- Avoid delayed repair or non-union.
- Maintain joint mobility and muscle strength.
- Physical therapy after removal of fixation aims to:
- Promote joint mobility and muscle strength.
- Prevent joint stiffness and muscle wasting.
Closed Reduction of Fractures
- Advantages: less invasive, shorter healing time, less risky, and leaves no scars.
- However, it cannot be done for all types of fractures (e.g., comminuted fractures).
Open Reduction of Fractures
- Involves the use of plate and screws, intramedullary nail, or external fixation.
- Also known as Open Reduction Internal Fixation (ORIF).
- Requires surgery to reduce the fracture.
Healing Process of Fractures
- Four main stages: Inflammation, Soft Callus Formation, Hard Callus Formation (Ossification), and Remodeling.
- Stage 1: Inflammation (4-5 days) - hematoma, swelling, and bruising.
- Stage 2: Soft Callus Formation - granulation tissue, fibroblasts, and cartilage formation.
- Stage 3: Hard Callus Formation (Ossification) - bone formation.
- Stage 4: Remodeling - bone reshaping.
Casts
- Made of:
- Plaster (POP) - white in color, hemihydrated calcium sulphate.
- Fiberglass - variety of colors, patterns, and designs.
- Inside of the cast: Cotton and other synthetic materials for padding and comfort.
Post-Cast Instructions
- Keep the limb elevated to prevent swelling.
- Apply an ice bag to the injured area.
- Keep the cast clean and dry.
- Check for cracks or breaks in the cast.
- Rough edges should be padded to protect the skin from scratches.
- Encourage patient to move their fingers or toes to promote circulation.
- Prevent small toys or objects from being put inside the cast.
- Do not put powders or lotion inside the cast.
- Cover the cast while eating to prevent food spills and crumbs from entering the cast.
