Gypsona S Plaster Splints by BSN Medical are the professional-grade choice for both medical immobilization and artistic casting. The 5" x 45" slab is the longest in the Gypsona splint lineup — purpose-built for full-leg immobilization, large-scale body casting, and applications where maximum coverage is essential. Each pre-cut slab features a plastic core to prevent shriveling and an interlocking leno weave gauze for superior structural stability.
What Are Plaster Splints Used For?
🏥 Medical Applications
The 5" x 45" length is the go-to choice for lower extremity immobilization and full-limb splinting. Orthopedic clinicians use this size for:
-
Long Leg Posterior Splints – for femur, tibia, and fibula fractures
-
Full Leg Cylinder Splints – for knee injuries and post-operative immobilization
-
Stirrup/U-Slab Splints – for ankle fractures and severe sprains requiring extended coverage
-
Coaptation Splints – for humeral shaft fractures needing full-length support
-
Posterior Ankle & Leg Splints – for complex lower extremity trauma
-
Pediatric Full-Leg Splints – where extra length allows trimming to fit
🎨 Artistic & Creative Applications
The 5" x 45" is the preferred choice for professional body casting artists who need maximum coverage with fewer strips:
-
Full Torso & Body Molds – complete chest, back, and torso casting in fewer passes
-
Belly Casts – pregnancy keepsake casting with wide, full-length coverage
-
Full Leg & Limb Casts – life casting for sculpture and fine art
-
Large Prop Making – film, stage, and costume props requiring large rigid panels
-
Sculpture Armatures – large-scale mixed-media and installation art structures
