How to use crutches
💡 What You Need to Know
- Purpose of Crutches: Crutches are essential mobility aids designed to reduce weight-bearing on an injured or surgically repaired lower extremity, such as after a joint replacement, promoting healing and preventing further damage.
- Proper Fitting is Key: Incorrectly fitted crutches can lead to discomfort, nerve damage, and increased risk of falls. Ensure the crutch pads are 1-2 inches below your armpits and the handgrips allow for a slight bend (20-30 degrees) in your elbows.
- Initial Training: Always receive instruction from a physical therapist or healthcare professional on the correct gait pattern and techniques for using crutches before attempting to ambulate independently.
- Weight-Bearing Status: Understand and strictly adhere to your prescribed weight-bearing restrictions (e.g., non-weight-bearing, touch-down weight-bearing, partial weight-bearing) as directed by your surgeon.
🤒 Associated Symptoms
- Post-Operative Pain: Significant pain following joint replacement surgery necessitates crutch use to offload the affected limb and manage discomfort during mobility.
- Muscle Weakness and Fatigue: Reduced strength in the surgical limb and general post-operative fatigue often require crutches to maintain balance and conserve energy during ambulation.
- Joint Instability: Immediately after surgery, the new joint may feel unstable, making crutches crucial for providing external support and preventing falls.
- Swelling and Edema: Post-surgical swelling can impact gait mechanics and comfort, making crutches necessary to reduce stress on the affected area.
- Impaired Balance: Anesthesia, pain medication, and the body's adjustment to a new joint can temporarily impair balance, making crutches vital for safe movement.
🛡 Crucial Precautions
- Avoid Slippery Surfaces: Exercise extreme caution on wet floors, ice, loose rugs, or uneven terrain to prevent slips and falls.
- Stair Negotiation: Always use the "up with the good, down with the bad" rule for stairs, using a handrail if available. A physical therapist should teach you the specific technique.
- Check Crutch Tips: Regularly inspect the rubber tips on your crutches for wear and tear. Worn tips reduce traction and increase fall risk; replace them promptly.
- Clear Pathways: Ensure your home environment is free of clutter, loose cords, and throw rugs to create safe walking paths.
- Proper Posture: Avoid leaning heavily on the axillary pads (underarm rests) to prevent nerve damage (crutch paralysis) in your armpits. Support your weight primarily through your hands.
🍽 Dietary Directions & Restrictions
- Adequate Hydration: Maintain excellent fluid intake (water, clear broths) to support healing, prevent constipation from immobility and pain medications, and maintain overall energy levels.
- Nutrient-Rich Diet: Focus on a balanced diet rich in protein for tissue repair, vitamins (especially C and D) and minerals (calcium) for bone healing, and complex carbohydrates for sustained energy.
- Fiber Intake: Increase dietary fiber through fruits, vegetables, and whole grains to prevent constipation, a common issue post-surgery due to reduced activity and medication side effects.
- Avoid Excessive Alcohol/Caffeine: Limit or avoid alcohol and excessive caffeine as they can impair judgment, affect balance, and interfere with sleep, all of which are critical for safe crutch use and recovery.
- Monitor Blood Sugar: If diabetic, maintain strict blood glucose control as high levels can impair wound healing and increase infection risk, impacting recovery and mobility.
⚠️ Attendant Guidelines
- Assist with Transfers: Provide stable support during transfers from bed to chair or vice versa, ensuring the patient has their crutches positioned correctly before attempting to stand.
- Home Safety Assessment: Help clear pathways, remove tripping hazards, and ensure adequate lighting, especially at night, to minimize fall risk.
- Medication Management: Assist with timely administration of pain medication and other prescribed drugs, understanding their potential side effects that might affect balance or alertness.
- Emotional Support: Offer encouragement and patience, as learning to use crutches and navigating post-operative recovery can be physically and emotionally challenging.
- Observe for Complications: Be vigilant for signs of infection (redness, warmth, discharge), deep vein thrombosis (calf pain, swelling), or other post-surgical complications, and report them immediately to the medical team.
🩺 Physician's Perspective
- Strict Adherence to Weight-Bearing: Your compliance with prescribed weight-bearing restrictions is paramount for the successful integration of your new joint and prevention of complications.
- Engage in Physical Therapy: Consistent participation in your physical therapy program is crucial for regaining strength, range of motion, and proper gait mechanics. Crutches are a temporary aid; therapy helps you progress beyond them.
- Effective Pain Management: Utilize prescribed pain medications as directed to allow for comfortable participation in therapy and mobility, but be aware of potential side effects.
- Follow-Up Appointments: Attend all scheduled post-operative follow-up appointments to monitor your recovery, assess joint stability, and adjust your rehabilitation plan as needed.
- Report Concerns Promptly: Do not hesitate to contact your surgical team if you experience increased pain, fever, redness, swelling, or any concerns regarding your crutch use or recovery.
🎓 Academic & Nursing Corner
- Crutch Fitting Assessment: Nurses must accurately assess and teach proper crutch fitting, ensuring axillary pads are 1-2 inches below the axilla and handgrips allow for 20-30 degrees of elbow flexion.
- Gait Training Reinforcement: Reinforce physical therapy instructions on various crutch gaits (e.g., 3-point gait for non-weight-bearing, 4-point for partial weight-bearing) and safe transfer techniques.
- Patient Education on Safety: Educate patients on fall prevention strategies, including clearing environmental hazards, using appropriate footwear, and avoiding leaning on crutches in the axilla.
- Monitoring for Complications: Assess for signs of axillary nerve compression (numbness/tingling in hands), skin breakdown under the arms, and signs of DVT or infection post-operatively.
- Documentation of Mobility: Accurately document the patient's weight-bearing status, type of gait, level of assistance required, and patient's understanding of crutch use.
🔬 Clinical Reference Index
- Types of Crutches: Differentiate between axillary crutches (most common for short-term non-weight-bearing) and forearm/Lofstrand crutches (often used for long-term support or partial weight-bearing, offering more freedom).
- Biomechanics of Crutch Gait: Understand how crutches alter the body's center of gravity and base of support, requiring increased upper body strength and coordination to maintain balance and propel forward.
- Axillary Nerve Compression: Recognize the risk of radial nerve palsy (crutch paralysis) due to prolonged pressure on the axillary nerve from improper crutch use, leading to wrist drop and sensory deficits.
- Energy Expenditure: Note that ambulating with crutches significantly increases energy expenditure compared to normal walking, impacting patient endurance and recovery.
- Progression of Weight-Bearing: Understand the clinical rationale behind progressive weight-bearing protocols post-joint replacement, from non-weight-bearing to full weight-bearing, guided by surgical stability and bone healing.
