What Is a Volar Splint and When Is It Used?

A splint is an orthopedic device used to support and immobilize an injured body part, promoting healing. A volar splint is a common type specifically designed for the wrist and hand. Its main function is to stabilize the injured area, reduce pain, and prevent further damage. This temporary immobilization allows bones, ligaments, and soft tissues to recover.

Understanding the Volar Splint

The term “volar” refers to the palm side of the hand or the sole of the foot. A volar splint is applied to the palmar aspect of the wrist and forearm, typically extending from the distal palmar crease to the mid-forearm. This design allows for free movement of the fingers and thumb while immobilizing the wrist joint.

Volar splints are commonly made from materials like plaster or fiberglass, which become rigid after molding. Some prefabricated options also exist, often crafted from thermoplastic materials that can be custom-fitted. The application process involves placing a stockinette directly on the skin, followed by cotton padding for cushioning, and then the wet splinting material. Once the material hardens, an elastic bandage secures it in place, ensuring the wrist is held in a slightly extended position.

Common Uses of a Volar Splint

Volar splints are widely used for a range of acute and chronic conditions affecting the wrist and hand. They are frequently applied for soft tissue injuries, such as severe wrist sprains. The splint provides stability, which helps reduce pain and swelling.

For fractures, volar splints are a common choice for certain carpal bone fractures and non-displaced proximal metacarpal injuries. They are particularly useful for distal radius fractures, immobilizing the wrist to allow bone fragments to unite. A volar splint can also be an effective treatment for inflammatory conditions like carpal tunnel syndrome, as it helps to keep the wrist in a neutral position to alleviate pressure on the median nerve.

Living with a Volar Splint

Wearing a volar splint requires specific care to ensure proper healing and prevent complications. It is important to keep the splint dry at all times, as moisture can lead to skin irritation, itching, or infection. When bathing, covering the splint with a plastic bag or using a waterproof shield is recommended, and if it does get wet, a hairdryer on a cool setting can be used for drying.

Patients should avoid inserting any objects under the splint to scratch an itch, as this can damage the skin or the padding, potentially leading to pressure sores or cuts. It is also important not to attempt to adjust or remove the splint without medical guidance, as improper positioning can hinder healing. Patients should monitor for signs that may indicate a problem, such as increased pain, swelling, numbness, a change in finger color, or a foul odor coming from the splint. Any of these symptoms warrant immediate contact with a healthcare professional. The typical duration of wear varies depending on the injury, but follow-up appointments are generally scheduled within two to seven days for assessment and potential adjustments.
