Veterinary Uses of Fiberglass Casts: Selection & Techniques

In veterinary practice, fiberglass casting tapes outperform plaster of Paris for many indications thanks to lighter weight, higher strength, better breathability, and radiographic clarity. From small-animal fracture immobilization to post-op support, outcomes depend on correct tape width/length, padding choice, and a consistent layup technique. This guide summarizes selection, preparation, and application steps for dogs and cats.

1) Proper Selection: Width, Length & Stiffness

• Tape width: 5 cm for small feline/puppy limbs, 7.5 cm for medium, 10 cm for large; proper width improves contour control and reduces pressure ridges.
• Roll length: plan 3–4 rolls for a medium forelimb/hindlimb depending on segment coverage.
• Set window: target gel time ~2–4 min and handling-free ~5–8 min for reliable molding.

2) Preparation: Alignment, Padding & Skin/Hair Protection

• Alignment: gentle traction and reduction where feasible; confirm perfusion and toe movement.
• Undercast padding: even layers with extra protection over bony prominences (carpus, tarsus, olecranon).
• Edge finishing: soften edges with moleskin to limit hair/skin abrasion.

3) Layup Technique & Molding

• Water activation: single dip in lukewarm water; gently express excess—avoid prolonged soaking.
• Overlap: 30–50% with gentle, even tension; avoid peaks/valleys.
• Molding: maintain limb contour during gel window; consider adjunct external splints for active animals.
• Joint inclusion: immobilize the joint above and below for fractures; tailor range limits for supportive casts.

4) Post-Casting Care

• Keep dry/clean: prevent wetting/mud; if damp, blot and use cool air.
• Owner monitoring: watch for odor, swelling proximal/distal to cast, discoloration/cold toes, or persistent licking.
• Behavioral protection: E-collar to prevent chewing; leash/crate restriction as needed.
• Follow-ups: scheduled skin checks and radiographs; adjust/replace if loose or cracked.

5) Red Flags & Complication Management

• Escalating pain, unusual restlessness, or cast intolerance
• Marked swelling, discharge, foul odor, or soft spots on the cast
• Cold/discolored distal limb, sudden paresis, or numbness
• Loose, cracked, or waterlogged casts
