Article Summary (TL;DR)

Stockinet is a seamless, circular rib-knit tubular cotton sleeve worn directly against the patient's skin. It acts as the primary moisture-wicking and anti-friction barrier beneath cast padding and rigid orthopedic casts.

Why Is Orthopedic Stockinet the First Layer of Defense?

Applying an orthopedic cast without a Stockinet directly exposes delicate epidermis to synthetic resins or coarse plaster particles. Stockinette provides a soft, breathable barrier that conforms to anatomical curves without causing vascular constriction.

How to Properly Apply Stockinet Under a Cast

  1. Measure the limb length and cut the stockinet leaving an extra 2 to 3 inches at both ends.
  2. Slide the tubular stockinet smoothly over the extremity, smoothing out any creases or folds.
  3. Apply a layer of Orthocot Cotton Roll evenly over the stockinet.
  4. Apply the rigid plaster or synthetic cast material.
  5. Fold the excess stockinet back over the cast edges before final wrap to create comfortable, rounded cuff borders.
