Here you can find a selection of supports that can be added to your thumb MCP or thumb combinations splints to provide additional support as needed for severe hyperextension or side deviation of the thumb joint. This listing is for the add on only and a thumb splint must be purchased in conjunction with a support from this listing. Supports can only be made from the same metal selected for the thumb splint. Orders for only an add on will be canceled.
 
In the first picture you will see the thumb single lateral support. This support helps for instances of lateral (sideways) deviation on one side of the thumb. This can sometimes occur due to hypermobility and laxity of the joint that causes it to slip sideways, or for instances of node growth or deformity that causes a bend in the joint. The support should go on the side that curves outward and can be used on either the MCP or IP joint (or both) for the IP/MCP combination splints and the MCP joint for all other types.
 
In the second photograph you will see the double lateral supports which are used for joints that have lateral (side-to-side) instability. They stabilize the joint from both sides to support and keep it in place while also preventing hyperextension. These supports can be used on either the MCP or IP joint (or both as shown) for the IP/MCP combination splints and the MCP joint for all other types. *****Can only be made for MCP joints in titanium*****
 
In the third photograph you will see the volar support. This support is used for cases of severe hyperextension of the thumb MCP joint. The splint supports the head of the MCP joint and stops it from slipping in towards the palm. This support is a good option for those with hyperextension greater tham 25 degrees or that can feel a popping sensation in the MCP joint when it hyperextends. This support can be added to any type of thumb splint.
 
In the 4th picture you will see the radial deviation support. This support is for instances when the thumb has deviation or deformity that causes the MCP joint to bend sideways. This support is also appropriate for injuries such as skiers thumb/gamer's thumb and to support common joint laxity with EDS to help protect the joint from deviation and further aggravation of the thumb tendons. For skiers thumb this splint would need to be used in conjunction with the ulnar (the side towards the back of the hand) single lateral support. This support can be added to any thumb splint except the IP/MCP Swirl.
 
This listing is NOT a splint, it is only to have supports added. A thumb splint will need to be purchased with this listing. If a thumb splint is not purchased with this listing it will be canceled.
