Everything You Need to Know About Finger Splints

Finger injuries or conditions can be both painful and inconvenient. Whether you’re dealing with a broken finger, arthritis, or tendon issues, a finger splint can be a vital tool in promoting recovery. This article explores everything you need to know about finger splints, their function, and how to get the most out of using them.

What Does a Splint Do?

A finger splint serves to protect and support your injured or strained finger. It helps by immobilizing the joint, reducing unnecessary movement, and ensuring the finger stays in the correct position for healing. Whether you’re dealing with a sprain, a fractured finger, or a condition like trigger finger, splints are designed to minimize pain and swelling while allowing ligaments and tendons to recover. 

Types of Finger Splints

Different types of splints are available depending on the type of injury or condition. It is best to have a healthcare professional fit or recommend the correct splint for your specific needs. 

• Buddy Taping (or Buddy Splinting): Buddy taping involves taping the injured finger to an adjacent, uninjured finger to provide mild immobilization and support. This technique is often used for minor sprains or small fractures that do not require extensive stabilization. By sharing the load with a healthy finger, buddy taping helps reduce strain on the injured digit while still allowing some controlled movement. 
• Stack Splint (Mallet Finger Splint): A stack splint is used specifically for mallet finger injuries, where the extensor tendon at the tip of the finger is damaged. These splints are commonly made of plastic or a semi-rigid material that cradles the fingertip, preventing it from bending and allowing the tendon to heal in a properly extended position. Typically, stack splints must be worn continuously for the duration recommended by a healthcare provider to ensure the tendon stays in optimal alignment. 
• Volar Splint: A volar splint is placed along the palm side (volar surface) of the finger to limit motion and support healing. It is particularly useful for fractures or other injuries needing immobilization in a neutral or slightly bent position. By restricting movement on the palm side, a volar splint promotes proper alignment and recovery while still permitting nearby joints to function normally. 
• Ring Splint: Ring splints are small, ring-shaped devices designed to stabilize specific finger joints, particularly for people with arthritis. They can help prevent hyperextension and limit deformities such as “swan neck” that can occur in rheumatoid arthritis. Ring splints may be custom-fitted or purchased off-the-shelf, and many people appreciate their discreet design and ease of use. 
• Aluminum Foam Splint: An aluminum foam splint features a thin, padded metal core that can be shaped to fit the contour of the injured finger. Its versatility makes it popular in clinics, as it can be molded to meet an individual’s unique needs and adjusted over time as swelling or healing progresses. These splints provide stability and comfort while remaining relatively lightweight and easy to maintain. 

Does Splinting Fingers Help Arthritis?

Yes, finger splints can be incredibly beneficial for managing arthritis symptoms. Splinting helps to reduce pain, support joints, and improve alignment. By immobilizing the affected joint, the splint provides stability which can significantly alleviate discomfort during daily activities. 

Arthritis-specific splints, like trigger finger splints, can also reduce pressure on inflamed tendons. Those with osteoarthritis or rheumatoid arthritis might find relief using thumb splints or tailored supports for other specific fingers. Remember, splinting is often complemented by physical therapy, which helps strengthen the surrounding muscles and improve overall hand function. 

How Long Should I Wear a Splint on My Finger?

The duration varies depending on the type of splint you’re using and the severity of your condition. Typically, for a broken or sprained finger, you might need to wear a splint for 2 to 6 weeks. Your doctor or therapist may recommend keeping your finger splinted until the bone or tendon has fully healed and motion no longer causes discomfort. 

For example, a finger splint for a broken finger may need to stay in place longer to ensure proper alignment. If you’re using a custom-fit splint, it might be adjusted periodically as the injury heals. Following your healthcare provider's advice is crucial, as wearing it too long or removing it too early can worsen the injury. 

Should I Wear My Finger Splint All Day? 

When you should wear your splint also depends on your specific injury and your doctor’s instructions. For acute injuries like fractures, it’s usually recommended to wear the splint at all times, even during sleep, to ensure the splint holds the finger in the right position. However, for chronic conditions like arthritis or mild tendon issues, your doctor may suggest wearing them only during activities that might stress the joint. 

Overuse of splints might weaken hand muscles, so balance is key. Combining splinting with physical therapy is often the best approach for achieving long-term relief and functional improvement. 

Choosing the Right Finger Splint for Your Needs

Selecting the appropriate finger splint begins with understanding the nature of your injury or condition. Different splints cater to specific issues—such as fractures, tendon injuries, or arthritic joints—so it’s important to identify the underlying problem before deciding on a splint. Consulting a healthcare professional is especially crucial, as misdiagnosis or incorrect splinting can prolong healing time or even exacerbate the injury. 

Comfort and proper fit are other essential factors when choosing a splint. A splint that is too tight can restrict blood flow, while one that is too loose may fail to provide adequate support. Ideally, the material should be rigid enough to offer stability yet padded or lined to reduce pressure on the skin. Pay attention to any signs of irritation or discomfort; these should be addressed promptly by a medical professional or a qualified hand therapist. 

Lastly, consider your daily activities and lifestyle. If you need to keep the splint on for an extended period, opt for one that can be easily cleaned, adjusted, and maintained. Some splints feature breathable materials or removable designs, making them more user-friendly for everyday wear. By taking into account both medical requirements and personal comfort, you can ensure that you select a finger splint that promotes healing while minimizing disruption to your daily routine. 

Finger splints are a practical solution for a wide range of injuries and conditions. From reducing pain to supporting arthritis management, they play a key role in recovery when used correctly. Always consult with a healthcare professional to determine the best type of splint for your needs and follow their advice to ensure your fingers heal properly.
