Fantastic boot! Super comfortable and love the air pump for additional ankle support. I actually put 20k steps on it the other day doing yard work and felt just fine. Highly recommended!

Long Arm Splint — Posterior Elbow Splint Kit for Elbow Fractures & Dislocations
The professional-grade long arm splint used by emergency departments and orthopedic clinics. If you've been searching for a long arm splint, posterior elbow splint, posterior plaster splint, long arm plaster splint, or plaster elbow splint — this is the upgraded fiberglass version that clinicians now use instead. Same posterior long arm immobilization. Lighter weight. Faster setting. More durable than plaster.
This complete professional-grade kit includes pre-padded synthetic fiberglass splint material, self-adhesive bandages, and synthetic padding for quick, effective treatment of elbow fractures, dislocations, and post-operative care — with no additional materials needed. Sets in just 5–7 minutes.
🔄 Replacing Plaster Elbow Splints? Fiberglass has replaced plaster as the clinical standard for long arm splints and posterior elbow splints. It's lighter, stronger, sets faster, and is more durable — while providing the same posterior immobilization as traditional plaster splint techniques used for elbow and forearm injuries.

What Is a Long Arm Splint?
A long arm splint — also called a posterior elbow splint, posterior long arm splint, or historically a posterior plaster splint — runs along the back (posterior) side of the arm from the upper arm, past the elbow, down the forearm to the wrist and hand. This design immobilizes the elbow joint in a stable position while preventing flexion and extension movements that could disrupt healing.
The long arm splint is the standard of care for elbow fractures, supracondylar fractures in children, and elbow dislocations. Historically, these splints were made from plaster of Paris — hence the common search terms posterior plaster splint and long arm plaster cast. Modern clinical practice has shifted to fiberglass, which sets faster, weighs significantly less, and is far more durable than traditional plaster splints, while providing the same quality of immobilization.

Application Instructions
⚠️ Important — Moisture Activation Warning: This fiberglass long arm splint material is moisture-activated — it begins hardening immediately when exposed to air, as the resin reacts with humidity naturally present in the atmosphere. Do not open the sealed pouch until you are fully prepared and ready to apply the splint. Once opened, the material will set in 5–7 minutes and cannot be reused. Keep the pouch sealed until the moment of use. Exposure to water will accelerate hardening.
Note: Some technicians use padding with their long arm elbow splints, and some do not, as you will see in these videos.

Frequently Asked Questions — Long Arm Splint & Posterior Elbow Splint
What is a long arm splint used for?
A long arm splint is used to immobilize the elbow, forearm, and wrist following fractures, dislocations, or severe sprains. It is the standard of care for elbow fractures (including distal humerus and olecranon fractures), supracondylar fractures in children, and elbow dislocations. The splint runs from the upper arm past the elbow to the wrist, preventing harmful movement during healing.
What is a posterior elbow splint?
A posterior elbow splint — also called a posterior long arm splint — is applied along the back (posterior) surface of the arm. This placement provides stable immobilization of the elbow joint while keeping the arm in a functional position. It is the most common splint configuration used for elbow fractures and dislocations in both emergency and orthopedic settings.
How long do you wear a long arm splint after an elbow fracture?
The duration depends on the type and severity of the fracture. Most elbow fractures require a long arm splint for 3–6 weeks. Supracondylar fractures in children are typically splinted for 3–4 weeks, while more complex fractures or post-surgical cases may require longer immobilization. Your orthopedic surgeon or treating physician will determine the appropriate duration based on X-ray healing progress.
Can a child use a long arm splint?
Yes. Long arm splints are commonly used for pediatric elbow fractures, particularly supracondylar fractures, which are among the most common fractures in children ages 5–10. Our kit includes a Child 6–12 size with appropriately scaled splint dimensions and bandage widths for smaller arms. Always have a medical professional evaluate and apply the splint for pediatric patients.
Is fiberglass better than plaster for a long arm splint?
Yes — fiberglass is now the clinical standard over plaster for long arm splints. Fiberglass is significantly lighter (reducing arm fatigue during wear), sets faster (5–7 minutes vs. 24–72 hours for plaster), is more durable and water-resistant, and is radiolucent for X-ray compatibility. Plaster splints are still used in some settings but fiberglass has largely replaced them in modern emergency and orthopedic care.
