3. Sizing and Fit

How to Measure and Choose Your Size

Proper sizing is crucial for effective support and comfort.

  1. Measure your neck circumference.
  2. Measure the depth from the sternal notch to the base of the mandible (jawline) in a straight line. This determines the required collar depth (Narrow 2.5", Average 3.0", or Wide 3.5").

Refer to the sizing chart below to select the appropriate circumference and depth.

OTC Cervical Collar Sizing Chart
Image Description: A sizing chart for the OTC Cervical Collar. It lists neck circumference ranges for X-Small (11.5-13.5"), Small (13.5-15.5"), Medium (15.5-17.5"), Large (17.5-19.5"), X-Large (19.5-21.5"), 2X-Large (21.5-23.5"), 3X-Large (23.5-25.5"), and 4X-Large (25.5-27.5"). It also indicates product number 2394, foam cervical collar, latex free, and white color.

For accurate measurements, take measurements first thing in the morning when swelling is least likely to be an issue. Keep the measuring tape in a level position without depressing the skin.

4. Application Instructions

How to Apply the Cervical Collar

  1. Position the narrowest part of the collar right under the chin.
  2. Fasten the closure straps at the back of the neck.

6. Troubleshooting

Common Issues and Solutions

  • Discomfort or Chafing: Ensure the collar is correctly sized and not too tight. Adjust the hook and pile closure for a comfortable, snug fit. If discomfort persists, consult a healthcare professional.
  • Insufficient Support: Verify that the collar's depth (2.5", 3.0", or 3.5") is appropriate for your neck length. If the collar is too short, it may not provide adequate stability. Consider re-measuring and selecting a different depth if necessary.
  • Skin Irritation: If skin irritation occurs, ensure the collar is clean and dry. Discontinue use if irritation persists and consult a healthcare professional.
