STACK SPLINT Oval Finger Splints — The Trusted Stack Splint for Pain-Free Living

If you’ve been searching for a stack splint that actually stays on, doesn’t bulk up your finger, and works around the clock — your search ends here. The STACK SPLINT Oval Finger Splints set delivers clinically trusted oval-ring splinting in a lightweight, waterproof shell. Designed for everyday heroes — typists, athletes, parents, musicians, and anyone managing a finger condition — this is the stack splint that moves with you.

What Is a Stack Splint? (And Why the Oval Design Wins)

A stack splint (also called a stax splint or oval-8 finger splint) is a small ring-shaped orthotic device that wraps around a finger joint to hold it in a straight, extended position during healing or pain management. Unlike bulky foam-and-tape alternatives, the STACK SPLINT’s open oval structure:

• Allows full airflow to prevent skin irritation
• Keeps the joint aligned without over-restricting movement
• Stays secure 24/7 — through water, sleep, and physical activity
• Delivers a clinical-grade fit without a clinic visit or custom fabrication

Who Needs a Stack Splint? Conditions STACK SPLINT Treats

The STACK SPLINT is recommended for a wide range of finger conditions. If your healthcare provider has suggested a stack splint for fingers, here’s exactly what this set addresses:

Mallet Finger

A stack splint for mallet finger is the gold-standard conservative treatment. The splint holds the fingertip in full extension continuously during the healing period, preventing the drooped DIP joint from scarring in a flexed position. The American Academy of Orthopaedic Surgeons (AAOS) recommends continuous splinting for 6–8 weeks for most mallet finger injuries. STACK SPLINT makes that protocol comfortable.

Trigger Finger (Stenosing Tenosynovitis)

Night splinting and activity-based protection using a stack splint for trigger finger can significantly reduce morning stiffness and locking. By holding the finger straight during sleep and low-activity periods, the tendon sheath gets the rest it needs to calm inflammation.

Arthritis (OA & RA)

Joint instability and pain from osteoarthritis or rheumatoid arthritis respond well to oval ring splinting. A finger splint for arthritis supports the joint through its range of motion, reducing pain on gripping, pinching, and typing without completely immobilizing the hand.

Hypermobility & EDS (Ehlers-Danlos Syndrome)

For people with hypermobile EDS or joint hypermobility syndrome, oval ring splints are a daily-wear essential. The STACK SPLINT hypermobility finger splint provides the proprioceptive feedback and range-of-motion limit that hypermobile joints need without surgery. The Ehlers-Danlos Society highlights splinting as a key conservative management strategy for hEDS.

Broken / Fractured Finger & Post-Surgery Recovery

During recovery from a broken finger or post-operative healing, maintaining correct alignment is critical. STACK SPLINT provides the stable, non-invasive extension needed to support bone and soft tissue healing without tape, foam, or aluminum that breaks down in water.

How to Size Your STACK SPLINT — Find the Right Fit

Getting the right stack splint size is critical for both comfort and effectiveness. Too loose and the splint won’t hold the joint in extension; too tight and it restricts circulation. Here’s how to measure:

• Step 1: Use a flexible tape measure or a thin strip of paper.
• Step 2: Wrap it around the widest part of the joint you need to splint — usually the DIP (fingertip) or PIP (middle) joint.
• Step 3: Note the circumference in inches and match to the size chart below:

SIZE CHART

Size	Joint Circumference
2	1.5″
3	1.6″
4	1.8″
5	1.9″
6	2.1″
7	2.3″
8	2.5″
9	2.7″

Why Choose STACK SPLINT Over Other Oval Finger Splints?

There are several stack splints for fingers on the market. Here’s why customers consistently choose STACK SPLINT:

• Complete set, one price: Most competitors sell individual splints. STACK SPLINT gives you all 8 sizes — perfect for finding your exact fit or covering multiple fingers.
• True waterproof build: Foam-and-velcro alternatives absorb water and lose their shape. STACK SPLINT’s solid plastic ring maintains its form through every shower.
• Durable beyond the first week: Tape and soft splints fray and degrade. STACK SPLINT is built to last weeks of continuous wear without compromise.
• Discreet in professional settings: The slim oval profile barely shows under a glove and doesn’t catch on keyboards, steering wheels, or fabrics.
• No-appointment solution: Get the same oval ring splinting recommended by hand therapists — without booking a clinic visit or paying for custom fabrication.

How to Use Your Stack Splint — Step-by-Step

Using your STACK SPLINT correctly maximizes both comfort and healing outcomes:

• Measure first: Confirm your size using the guide above before wearing.
• Slide on gently: Position the splint over the affected joint with the wider opening at the top and the narrower band under the joint.
• Check the fit: You should be able to slip one fingernail under the edge. Snug but never pinching.
• Wear consistently: For mallet finger and fracture recovery, wear continuously day and night (remove only to wash the splint).
• Clean regularly: Rinse with mild soap and warm water; dry with a soft cloth.

Always follow guidance from your physician or certified hand therapist (CHT) regarding your specific protocol. STACK SPLINT is a supportive aid — it does not replace professional medical advice.
