Air X CMC Joint Thumb Restriction Splint

The Air X CMC Joint Thumb Restriction Splint allows for uninterrupted finger function whilst providing unrivalled support to the thumb and to the MCP and CMC joints. Ideal for the treatment of osteoarthritis and joint fractures, the Air X Restriction Splint supports and hold the thumb in place whilst it heals, preventing further damage to the MCP and CMC joints further down the hand.

What's Included?

  • 1 x Thumb Splint

What Are the CMC and MCP Thumb Joints?

The CMC joint is located at the base of the hand, attaching the first half of the thumb to the lower part of the hand. The MCP joint is located at the middle of the thumb, attaching the visible part of the thumb to your hand.

How Does an Air X Splint Help Heal the CMC and MCP Joints?

By providing a diverse level of compression at multiple points of the thumb and hand, both the CMC and MCP joints are isolated and cradled, allowing them to heal properly following an injury. The strap that wraps over the hand and around the thumb doubles down on this support, ensuring any bumps or light-impact throughout the day wont dislodge either of these joints. 

What Are the Benefits of Thumb Isolation?

Thumb isolation ensures movement and interaction are limited, allowing the thumb to rest and recuperate following an injury. Isolation allows the main CMC and MCP joints to rest, reducing inflammation, soreness, discomfort and pain. 

Sizing Information for the Air X Thumb Restriction Splint

To find the perfect size splint for your hand, please measure the circumference of your wrist in the area shown in the image below. As the Air X Splint is a tight-fitting splint, we recommend loosely measuring the area below.

Once you have your measurement, please consult the sizing chart below to find the correct splint size for your hand.

Measure the bony part of the wrist as indicated

Size Wrist Circumference
Infant 11 - 14cm
Child  14 - 17cm
Small 15 - 18cm
Small+ 17 - 18cm
Medium 18 - 20cm
Medium+ 20 - 21cm
Large  20 - 23cm
Large+ 21 - 24cm
Extra Large 23 - 25cm

Please note, the Air X Splint is a restriction splint and is designed to fit tightly. If you are concerned about this or fall on a sizing boundary, please select a size up.

Why Measure the Wrist?

As the Air X Splint provides compressive support designed to provide support to the CMC joint, measuring your wrist gives the best indication as to which splint size will fit correctly. If you are concerned about the tightness of the brace, or you fall on a sizing boundary, we recommend you select a size up for maximum comfort and benefit.

What Makes Air X Fabric Better Than Other Materials?

The unique Air X fabric has the ability to transport moisture efficiently away from the body thanks to the layered fibre structures, which help promote moisture wicking. This results in a dry, comfortable feeling on the surface of the skin, helping your hand to feel fresh throughout the day.

Air X fabric is also a soft, lightweight material that perfectly follows the contours of the body. This means the Air X adapts and shapes itself to the individual wearing it, providing exceptional comfort, even for extended periods of a time.

When Is a Splint Better Than a Brace?

Wrist and thumb braces work by providing stabilisation instead of immobilisation, which helps to protect you from further injury while allowing the completion of day-to-day tasks. A brace provides the perfect combination of gentle support, stabilisation and mobility. Wrist splints are generally more rigid, providing full immobilisation, and are often used for more severe injuries or earlier on in the rehabilitation process. 

Unique and Innovative AirX Foundation Fabric

Wearing any type of splint for an entire day can cause sweat and perspiration to build up on the hand and inside the brace, causing irritation, discomfort and existing dermatological issues to compound. The AirX brace uses an innovative and comfortable fabric design to draw sweat and perspiration away from the skin, releasing moisture into the air to prevent it building up inside the brace.
