Types of Crutches
Understanding the different types of crutches will help you choose the right one for your needs. Each type has specific advantages depending on your injury, strength, and lifestyle.
1. Axillary Crutches (Underarm Crutches)
Most Common Type - These are the traditional crutches that fit under your armpits.
- Best for: Short-term use (6-8 weeks), temporary injuries, post-surgery recovery
- Pros: Easy to learn, widely available, affordable ($20-$50)
- Cons: Can cause underarm discomfort, risk of nerve damage if used incorrectly
- Weight capacity: Typically 250-300 lbs
⚠️ Important: Never rest your weight on your armpits! This can cause nerve damage (crutch palsy). Your weight should be on your hands and handgrips.
2. Forearm Crutches (Lofstrand/Canadian Crutches)
Professional Choice - These crutches have a cuff that goes around your forearm with a handgrip below.
- Best for: Long-term use, permanent mobility needs, active lifestyles
- Pros: More maneuverable, better for stairs, allows hand freedom, less tiring
- Cons: Steeper learning curve, requires more upper body strength ($50-$150)
- Weight capacity: 250-350 lbs depending on model
3. Platform Crutches
Specialized Support - Your forearm rests on a platform with a vertical handgrip.
- Best for: Weak grip, arthritis, hand/wrist injuries, neurological conditions
- Pros: No weight on hands/wrists, comfortable for extended use
- Cons: Bulkier, more expensive ($100-$300), less common
- Weight capacity: 250-400 lbs
4. Hands-Free Crutches (Knee Scooters/iWALK)
Modern Alternative - Strap your leg in and walk using your good leg.
- Best for: Below-knee injuries, active individuals, those unable to use hands
- Pros: Hands completely free, less tiring, maintains upright posture
- Cons: Not suitable for all terrains, requires good balance ($150-$400)
- Weight capacity: 275-400 lbs
Proper Sizing Guide
Correct sizing is crucial for comfort, safety, and preventing secondary injuries. Improperly sized crutches can cause shoulder pain, wrist strain, and posture problems.

Axillary Crutch Sizing
Method 1: Standing Measurement (Most Accurate)
- Stand upright in comfortable shoes
- Position crutches 6 inches forward and 6 inches to the side of your toes
- Top pad should be 1-2 inches (2-3 finger widths) below your armpit
- Handgrip should align with your wrist crease when arms hang naturally
- Elbows should bend at 15-30 degrees when gripping handles
Method 2: Lying Down Measurement
- Lie flat on your back
- Measure from 6 inches out from your heel to your armpit
- This measurement = crutch length from bottom to top pad
Method 3: Height Estimation (Less Accurate)
- 5'0" - 5'3": Child/short adult crutches (48-50")
- 5'4" - 5'7": Medium adult crutches (52-54")
- 5'8" - 6'2": Tall adult crutches (56-58")
- 6'3"+: Extra tall crutches (60-62")
Forearm Crutch Sizing
- Handgrip height = same as wrist crease when standing with arms down
- Forearm cuff should be 1-1.5 inches below elbow (about 2-3 finger widths)
- Cuff should fit snugly but not restrict circulation
- Elbow should bend at 15-30 degrees when gripping handle
Insurance Coverage: Most insurance plans (including Medicare) cover crutches when prescribed by a doctor. Save your receipts and obtain a prescription beforehand. See our Insurance Guide for details.
Step-by-Step Fitting Instructions
Adjusting Axillary Crutches
- Adjust overall length:
- Press the spring-loaded buttons on the sides
- Slide inner tube up or down
- Release when holes align with proper height
- Ensure buttons click fully into place
- Adjust handgrip height:
- Loosen wing nut or press button on handgrip
- Move grip up or down
- Tighten securely - test before use
- Test the fit:
- Stand with crutches - check 2 finger gap below armpit
- Grip handles - elbows should bend slightly (15-30°)
- Walk a few steps - adjust if discomfort occurs
Adjusting Forearm Crutches
- Adjust the shaft length by loosening clamps/buttons
- Set handgrip at wrist level when standing
- Adjust forearm cuff 1-1.5 inches below elbow
- Tighten all adjustment points securely
- Test walk and readjust as needed
⚠️ Safety Check: After adjusting, always verify that all pins, buttons, and clamps are fully secured. A loose crutch can collapse under your weight, causing falls and further injury.
Common Mistakes to Avoid
1. Resting Weight on Armpits
The Problem: This is the #1 mistake beginners make. It can cause "crutch palsy" - nerve damage in the armpit area leading to numbness, tingling, or even temporary paralysis in the arm.
The Fix: Keep 2-3 finger widths of space between armpit and pad. Your hands should bear your weight, not your armpits.
2. Incorrect Sizing
The Problem: Too tall = shoulder/neck strain; too short = hunched posture and back pain.
The Fix: Follow the sizing guide above or use our calculator. Re-check fit after first use.
3. Looking Down While Walking
The Problem: Looking at your feet throws off balance and posture, increasing fall risk.
The Fix: Keep your head up, eyes forward. Trust your crutch placement.
4. Worn Rubber Tips
The Problem: Slippery tips are a major fall hazard, especially on smooth or wet surfaces.
The Fix: Inspect tips weekly. Replace when tread wears smooth or rubber cracks. Tips cost $5-$15/pair.
5. Going Too Fast Too Soon
The Problem: Rushing before you're comfortable leads to falls and re-injury.
The Fix: Practice at home first. Master the basics before tackling stairs, uneven terrain, or long distances.
When to Use Crutches vs. Other Aids
Use Crutches When:
- You can bear partial or no weight on one leg
- Recovery time is expected to be 6-12 weeks
- You have good upper body strength and balance
- You need to navigate stairs regularly
- Your injury is below the knee
Consider a Walker or Wheelchair When:
- You have balance problems or are at high fall risk
- You lack upper body strength
- You have injuries to both legs
- Recovery period is very long (3+ months)
- You're elderly or have other medical conditions
Consider a Cane When:
- You can bear most weight on your injured leg
- You only need light support for balance
- You're transitioning away from crutches
- Your mobility is mostly restored
Ask Your Doctor: Your healthcare provider can help you choose the best mobility aid for your specific condition, age, and lifestyle. They can also provide a prescription for insurance coverage.
