What a custom silicone thumb prosthesis can offer, and what's specific about restoring a thumb rather than another finger.
The thumb is the hand's most important digit for function, so losing one, or part of one, can feel particularly significant. A custom silicone thumb prosthesis can restore the natural appearance of the hand. This guide covers what is specific about a thumb, and what to expect.
The thumb accounts for a large share of the hand's function, and it sits and moves differently from the other fingers. That means a thumb prosthesis is designed with its particular shape, position and role in mind. A clinician experienced in these devices will assess how much of the thumb remains and what a prosthesis can realistically achieve for you.
A custom silicone thumb is sculpted to your residual thumb and matched to your skin tone and nail, restoring the look of a complete hand. Depending on how much thumb remains, it can also help with light function, such as providing a surface to stabilise or oppose objects against, and can protect a sensitive residual thumb.
A silicone thumb prosthesis restores appearance and can offer light functional benefit and protection, but it does not restore the grip strength, movement and sensation of a natural thumb. Where significant functional restoration is the priority, a clinician can discuss whether other options may suit you better, or alongside.
As with any custom finger prosthesis, you work through a registered clinician, who assesses your hand, takes the impression and measurements, matches the colour, and fits the finished device. BioDigit makes the prosthesis to specification and quality-checks it; the clinician fits it and supports you.
