Mallet Finger Splint | EVA & Aluminum Alloy DIP Joint Brace

Mallet Finger Splint with EVA and Aluminum Alloy Support for DIP Joint Extension and Post-Surgical Recovery

Designed for adults managing mallet finger (extensor tendon injury at the distal interphalangeal joint), finger contractures, long-term finger injury, finger arthritis, and post-surgical finger recovery — including mallet finger caused by ball sports such as baseball and cricket — our Mallet Finger Splint is constructed from soft EVA and aluminum alloy metal plates with a spring design, holding the DIP joint in an extended position during wear to support the extensor tendon during conservative management and rehabilitation. The breathable fabric outer layer sits comfortably against the finger skin during extended day and night use. The adjustable elastic closure with anti-slip construction provides a secure, customizable fit across sizes S, M, and L. Fits the index, middle, ring, and little fingers of either hand — does not fit the thumb. Single piece. Adults. Ships from US, Canada, Australia, and Europe. $13.00.

Soft EVA and Aluminum Alloy Metal Plates With Spring Design — Structural DIP Joint Extension Support: The splint is constructed from two primary structural components. The soft EVA (ethylene-vinyl acetate) layer provides a cushioned, lightweight base that sits comfortably against the finger tissue during extended day and night wear without creating pressure points against the injured digit. The aluminum alloy metal plates provide the rigid structural support needed to hold the DIP joint in an extended position during wear — the standard positioning requirement for conservative mallet finger management. The spring design within the aluminum alloy construction allows a degree of controlled flex while maintaining the DIP joint extension positioning during daily activity and overnight rest. Always confirm the correct DIP joint extension angle and positioning with your hand surgeon or hand therapist before applying this splint for mallet finger.

Fits Index, Middle, Ring, and Little Finger — S, M, and L Sizing for Correct Finger Width and Length Fit: The splint is designed to fit the index finger, middle finger, ring finger, and little finger of either the left or right hand — it does not fit the thumb. The S, M, and L size variants correspond to different finger circumference and length dimensions — refer to the size chart above to select the correct size for the specific finger being splinted. Selecting the correct size is important for achieving the snug, secure fit needed to maintain DIP joint extension positioning during wear. One splint per purchase — order the quantity required if multiple fingers need simultaneous splinting. A hand surgeon or hand therapist can confirm which finger size to select for your specific mallet finger condition.

Breathable Fabric Outer Layer — Comfortable Extended Day and Night Wear: The outer layer of the splint is constructed from breathable fabric that sits directly against the finger skin during wear — allowing air circulation through the splint structure during extended all-day and overnight use. The breathable construction reduces heat buildup and moisture accumulation against the injured finger during prolonged wear — particularly important for mallet finger management, which typically requires continuous DIP joint extension splinting for 6–8 weeks during the conservative management protocol. The breathable fabric is designed to protect the soft tissue of the finger with a laminated fit against the digit during wear, reducing the risk of accidental re-injury during daily activity.

Adjustable Elastic Anti-Slip Closure — Secure Customizable Fit That Stays in Position During Activity: The splint features an adjustable elastic closure that allows the tension and fit to be freely customized to the individual finger width and the required compression level — achieving a snug, secure fit that holds the splint firmly in position during finger movement without slipping, gathering, or rotating during daily activity and overnight sleep. The anti-slip construction prevents the splint from sliding along the finger during movement — maintaining consistent DIP joint extension positioning throughout the wear period. The elastic closure is not easy to deform, maintaining its fit and compression performance during repeated daily adjustment across the splinting protocol duration.

Conditions and Use Cases — Mallet Finger, Finger Contractures, Arthritis, Long-Term Injury, and Post-Surgical Recovery: The splint provides DIP joint extension support and protective finger immobilization for a range of conditions: mallet finger (extensor tendon avulsion at the DIP joint) from ball sports including baseball, cricket, basketball, and volleyball; finger contractures requiring extension positioning during rehabilitation; long-term finger joint injury management; finger arthritis requiring protective support during activity; and post-surgical finger recovery requiring protective splinting during rehabilitation. Always confirm the appropriate splinting approach, DIP joint positioning, and continuous wear protocol with your hand surgeon or hand therapist before use for any diagnosed finger condition.

Frequently Asked Questions about the Mallet Finger Splint

Q: What is mallet finger and why does the DIP joint need to be held in extension?

A: Mallet finger is an injury to the extensor tendon at the tip of the finger — most commonly caused by a ball striking the fingertip during baseball, cricket, basketball, or volleyball, forcing the DIP joint into sudden flexion and avulsing or rupturing the extensor tendon. Conservative management requires the DIP joint to be held continuously in full extension for 6–8 weeks to allow the extensor tendon to heal in the correct position. Any DIP joint flexion during this period restarts the healing timeline. A hand surgeon or hand therapist must confirm the correct positioning and continuous wear protocol for your specific injury before use.

Q: How do I select the correct size S, M, or L?

A: Refer to the size chart above, which provides finger circumference and length measurement guidelines for S, M, and L. Measure the circumference of the specific finger being splinted at the DIP joint and select the size that corresponds to your measurement. If between sizes, consult your hand therapist who can advise on the tighter or looser fit appropriate for your specific mallet finger management protocol.

Q: Does it fit the thumb?

A: No — this splint is designed to fit the index, middle, ring, and little fingers only. It does not fit the thumb. If you need a thumb-specific splint, a hand therapist can recommend the appropriate thumb spica splint or equivalent for your thumb condition.

Q: Can it be worn continuously day and night?

A: Yes — the breathable fabric outer layer and adjustable elastic closure are designed for continuous day and night wear during the mallet finger conservative management protocol. Mallet finger typically requires uninterrupted DIP joint extension splinting — always follow the continuous wear schedule prescribed by your hand surgeon or hand therapist, as removing the splint and allowing DIP joint flexion during the healing period can restart the tendon healing timeline.

Q: Is it suitable for finger arthritis?

A: The splint provides DIP joint extension positioning and protective support that may be suitable for managing discomfort associated with finger arthritis during daily activity. Always confirm suitability, the correct joint positioning, and wear schedule with your rheumatologist, hand therapist, or physician before use for an arthritis-related finger condition.

Disclaimer: This product is a supportive finger splint intended to provide DIP joint extension positioning and protective support during mallet finger conservative management, finger injury rehabilitation, and post-surgical recovery. It is not a medical device and is not intended to diagnose, treat, cure, or prevent any medical condition, including mallet finger, extensor tendon injury, finger contractures, finger arthritis, or any other finger or hand condition. Results vary by individual. Mallet finger requires a specific continuous DIP joint extension splinting protocol — always consult a qualified hand surgeon, hand therapist, or orthopedic specialist before use, and follow the splinting protocol and wear schedule prescribed by your clinical team. Do not use as a substitute for prescribed medical treatment, surgical intervention, or professional clinical assessment.
