The modern fiberglass replacement for the traditional plaster thumb spica splint. If you've been searching for a plaster thumb spica, plaster thumb splint, or thumb spica plaster cast — this is the upgraded fiberglass version that clinicians now use instead. Same thumb and wrist immobilization with the thumb in the functional position. Lighter weight. Faster setting. More durable than plaster.
This complete professional-grade kit includes pre-padded synthetic fiberglass splint material, bandage, and gloves for quick, effective thumb immobilization — with no additional materials needed. Sets in just 5–7 minutes.

Frequently Asked Questions
What is a thumb spica splint used for?
A thumb spica splint immobilizes the thumb and wrist in a functional position to allow healing of injuries to the thumb, wrist, and surrounding structures. It is the standard of care for scaphoid fractures, gamekeeper's thumb (ulnar collateral ligament tears), skier's thumb, De Quervain's tenosynovitis, and proximal or distal phalanx fractures of the thumb. The spica design extends from the forearm to the tip of the thumb, leaving the fingers free for daily activities.
How long do you wear a thumb spica splint after a scaphoid fracture?
Scaphoid fractures typically require 8–12 weeks of immobilization in a thumb spica splint or cast, depending on fracture location and displacement. Non-displaced fractures of the scaphoid waist are often treated conservatively with a thumb spica for 10–12 weeks. Proximal pole fractures may require surgical fixation followed by splinting. Your orthopedic surgeon will determine the appropriate duration based on imaging and clinical assessment.
What is the difference between gamekeeper's thumb and skier's thumb?
Both terms refer to injury of the ulnar collateral ligament (UCL) of the thumb's metacarpophalangeal (MCP) joint, but they differ in mechanism. Gamekeeper's thumb is a chronic, repetitive-stress injury historically seen in gamekeepers who repeatedly stressed the UCL. Skier's thumb is an acute traumatic UCL tear, typically caused by a fall on an outstretched hand while holding a ski pole. Both are treated with thumb spica immobilization; complete tears may require surgical repair followed by splinting.
Can I apply a thumb spica splint at home?
This kit is designed for application by trained medical professionals — physicians, physician assistants, nurses, athletic trainers, and emergency medical technicians. Proper application requires knowledge of thumb anatomy, correct positioning in the functional position (slight extension and abduction), and appropriate padding technique to prevent pressure sores. If you are a patient, this kit should be applied by your healthcare provider. Always consult a physician for diagnosis before splinting any suspected fracture.
How long does fiberglass take to set compared to plaster?
Fiberglass splint material sets in 5–7 minutes and reaches full strength within 30 minutes. Plaster of Paris typically takes 24–72 hours to fully cure and reach maximum strength. Fiberglass is also significantly lighter (approximately 40–50% lighter than plaster), more durable, and radiolucent — meaning X-rays can be taken through the splint without removal. These advantages have made fiberglass the preferred material in emergency departments and orthopedic clinics.
