Purpose and Principles of Traction
Traction is the application of a pulling force to a specific part of the body. In orthopedic nursing, this mechanical force serves several vital therapeutic goals.
- Realignment: Restoring bone fragments to their normal anatomical position after a fracture.
- Muscle Spasm Reduction: Overstretching cramped muscles around an injured bone to relieve severe pain.
- Contracture Prevention: Stretching tight soft tissues and joint capsules to maintain range of motion.
- Immobilization: Holding a healing limb steady so bone ends can knit back together safely.
Effective traction relies on basic physics. Every pull requires an equal and opposite counter-traction. For counter-traction to work, the patient's own body weight typically pulls in the opposite direction, which means nurses must keep the patient properly aligned in bed.
Skin Traction Versus Skeletal Traction
Orthopedic traction is broadly divided into two main categories based on how the pulling force is applied to the patient's body.
- Skin Traction: Force is applied directly to the skin using adhesive tape, foam boots, or straps. This method is non-invasive, short-term, and uses lighter weights (usually 2 to 5 kilograms) to relieve muscle spasms. Buck's traction for hip fractures is a common example. Nurses must monitor the fragile skin underneath for irritation and breakdown.
- Skeletal Traction: Force is applied directly to the bone using surgically inserted pins, wires, or tongs. This method allows much heavier weights (7 to 12 kilograms or more) and can remain in place for weeks or months. Balanced suspension skeletal traction is frequently used for complex femoral fractures. The primary nursing concern here is preventing infection at the pin insertion sites.
Maintenance of Traction Mechanics
For traction to achieve its healing purpose, the mechanical setup must remain completely undisturbed. Nurses play a frontline role in checking equipment integrity during every shift.
- Weights Must Hang Freely: Weights should never rest on the floor, bed frame, or window sill. If weights touch the floor, the pulling force is instantly lost.
- Ropes Must Be Unobstructed: Ropes must move smoothly through all pulley grooves without fraying or catching on bedding.
- Knot Inspection: Knots in the ropes should be tight and never rest against the pulleys, which would block movement.
- Prescribed Weight Amount: Never add, remove, or adjust traction weights unless a specific medical order is documented.
Comprehensive Nursing Assessments
Caring for a patient in traction requires systematic, frequent monitoring to catch complications early. The mnemonic NEUROVASCULAR assessment is the bedrock of safe care.
- Circulation: Check peripheral pulses distal to the injury, skin color, and capillary refill time.
- Motion: Ask the patient to wiggle their toes or fingers depending on the affected limb.
- Sensation: Assess for numbness, tingling, or the inability to feel light touch, which indicates nerve compression.
- Pain: Evaluate the character and intensity of pain. Severe, unrelieved pain that does not respond to prescribed analgesics often signals compartment syndrome, a true surgical emergency.
Pin Site Care for Skeletal Traction
Skeletal traction pins penetrate the skin and bone, creating a direct pathway for bacteria to enter. Meticulous pin site care prevents local skin infection from progressing into osteomyelitis.
- Aseptic Technique: Always perform pin site care using strict aseptic technique and sterile equipment.
- Cleansing Agent: Use sterile normal saline or a prescribed antiseptic solution, working in a circular motion outward from the pin.
- Crust Removal: Gently remove dried serosanguineous drainage or crusts, as they can trap bacteria underneath against the skin.
- Dressing Policy: Follow hospital protocol regarding whether pin sites should be covered with sterile gauze or left open to the air.
- Loose Pin Warning: Never tighten a loose pin yourself; report any wobbling or instability to the surgical team immediately.
Prevention of Immobility Complications
Prolonged bed rest associated with traction places patients at high risk for systemic complications. Nursing interventions must target multiple body systems simultaneously.
| Body System | Potential Complication | Preventive Nursing Action |
|---|
| Respiratory | Atelectasis, Pneumonia | Encourage deep breathing, incentive spirometry, and coughing |
| Cardiovascular | Deep Vein Thrombosis (DVT) | Apply compression stockings and encourage active ankle pumps |
| Integumentary | Pressure Ulcers | Reposition frequently within limits, use pressure-relieving mattress |
| Gastrointestinal | Constipation | Increase fluid intake, dietary fiber, and administer stool softeners |
Patient Education and Support
Being confined to bed in traction is emotionally and physically exhausting. Patients often experience feelings of helplessness, boredom, and anxiety about their long-term recovery.
Nurses should involve patients in their daily care plan by teaching them how to use the overhead trapeze bar to lift themselves for skin checks and bedpan use. Clear communication about the expected timeline for fracture healing helps reduce anxiety. Providing diversional activities such as books, radios, or visits from family members combats isolation. Emotional support combined with patient participation fosters a sense of control during a difficult hospitalization.
