The Cast Glossary: 30 Essential Terms Every Cast Lover Should Know

The Cast Glossary: 30 Essential Terms Every Cast Lover Should Know

If you've spent any time in cast forums, Pinterest boards, or medical literature, you've probably run into a wall of acronyms and jargon. SLC, LLC, NWB, PWB, WBAT, fiberglass, gore-tex, walking heel, stockinette… it's a whole vocabulary. This glossary is the cheat sheet we wish we had when we started — thirty terms every cast lover, simulation enthusiast, and curious newcomer should know, with plain-English definitions and how each one relates to the experience you're building.

Cast types and lengths

SLC — Short Leg Cast. Covers from below the knee to the toes. Used for ankle and foot injuries. Knee remains free.

LLC — Long Leg Cast. Covers from the upper thigh to the toes. Knee is locked straight or in slight flexion. The most iconic and immersive cast configuration. Reproduced safely by our LLC Brace.

Cylinder cast. Long leg cast that ends at the ankle, leaving the foot free. Used for knee injuries.

SAC — Short Arm Cast. Wrist to just below the elbow.

LAC — Long Arm Cast. Wrist to upper arm, elbow bent at 90 degrees.

Spica cast. Includes the trunk and one or both legs. Used after major hip surgery in real medicine. Rarely simulated due to complexity.

PTB — Patellar Tendon Bearing cast. A short leg cast with extra molding around the kneecap to allow weight-bearing.

Bivalved cast. A cast that has been cut in half lengthwise so it can be opened and closed. Functionally similar to our removable LLC Brace.

Cast materials

Plaster of Paris. The classic white cast. Heavy, takes 24-48 hours to fully dry, beautiful when freshly applied. Now mostly historical.

Fiberglass. Modern standard. Lighter, faster setting, available in colors. What you see in 90% of casts since the 2000s.

Gore-Tex / waterproof liner. A breathable membrane that lets a fiberglass cast get wet without damage. Premium option.

Stockinette. The soft cotton tubular sock applied directly against the skin before padding.

Webril. Brand name for the soft cotton cast padding wrapped over the stockinette.

Cohesive bandage. Self-sticking elastic bandage. Used for compression and adding padding under a brace.

Weight-bearing terms (medical shorthand)

NWB — Non Weight Bearing. The casted leg cannot touch the ground at all. Crutches mandatory. The default for fresh long leg casts.

TTWB — Toe Touch Weight Bearing. The casted foot can touch the ground for balance only, no actual weight.

PWB — Partial Weight Bearing. 25% to 50% of body weight allowed on the casted leg.

WBAT — Weight Bearing As Tolerated. Patient self-regulates based on pain. The recovery stage.

FWB — Full Weight Bearing. Normal walking allowed.

Mobility and equipment

Axillary crutches. The classic underarm crutches. American standard. See our Crutches 101 guide.

Forearm crutches (Lofstrand or Canadian crutches). Single cuff around the forearm. European standard, used for long-term patients.

Walking heel / cast shoe. A small rubber sole molded into a fiberglass cast or a sandal-style overshoe, allowing the wearer to walk on a short leg cast.

Knee scooter. A wheeled platform you rest the knee on while pushing with the other leg. Alternative to crutches for SLC patients.

Three-point gait. The standard crutch walking pattern when one leg cannot bear weight. Crutches forward, swing through, repeat.

Lift shoe. A thicker-soled shoe worn on the good foot to compensate for the cast's added height. Critical for hip alignment.

Community vocabulary

Cast lover. A person with a strong aesthetic, sensorial, or emotional attraction to casts and cast immobilization.

Cast curiosity. The early-stage interest in the cast experience, often before someone identifies as a "cast lover" — a softer, more exploratory term.

Pretender. Someone who simulates a cast or other medical condition without injury. The community is generally supportive and educational.

Devotee. Someone attracted to people who wear casts or use mobility aids, rather than to wearing them themselves.

Wannabe. Someone who wishes for actual injury. Different from pretenders. Generally discouraged in healthy communities, which emphasize safe simulation alternatives like the LLC Brace.

Sim or simulation. A pretender's setup. Refers to creating a realistic cast experience without injury.

Self-cast. Building a cast on yourself with real fiberglass or plaster. Possible, but irreversible without scissors and risks circulation issues. Usually discouraged in favor of removable braces.

Safety and clinical terms

Compartment syndrome. A serious medical emergency where pressure builds up inside a cast and cuts off circulation. Real risk with self-cast attempts. The reason removable braces exist.

Crutch palsy. Nerve damage in the armpit caused by leaning on crutch pads instead of using the hands. Easily avoided with correct technique.

Maceration. Skin breakdown caused by prolonged moisture trapped against skin. Why hygiene under a cast matters.
