For people born with a finger difference, what a custom silicone prosthesis can offer, explained sensitively and honestly.
A congenital finger difference, being born with a finger that is absent, partial or formed differently, is part of who someone is, and many people live confidently without any wish to change it. For others, at some point, a prosthesis that restores a typical hand appearance is something they want to explore. Both choices are valid. This guide is for those considering the option.
It is worth saying clearly: there is nothing that needs "fixing" about a limb difference, and a prosthesis is a personal choice, not a necessity. People consider one for their own reasons, often around confidence in particular situations, and that decision belongs entirely to the individual (or, for a child, to the family, guided by what is right for the child). There is no wrong answer.
A custom silicone prosthesis can restore the appearance of a typical finger, sculpted and colour-matched to the hand. For someone who wants it, this can offer confidence in settings where they would prefer their hand not to draw attention. Depending on the anatomy, it may also offer light function and protection.
Congenital differences vary widely, in which finger is involved, how it is formed, and what tissue is present. That makes individual assessment especially important; what is achievable depends entirely on the specific anatomy. A clinician experienced in these devices will assess carefully and be honest about what a prosthesis can and cannot do in a particular case.
Where a child is involved, timing and suitability are considerations a clinician and family weigh together, and a child's own growth and views matter. These decisions are made thoughtfully, with the child's wellbeing first, and always led by the treating clinician.
As with any custom prosthesis, the route is through a registered clinician who assesses the hand, plans the device, and fits it. BioDigit makes the prosthesis and supplies the clinician; the clinical judgement and care stay with the clinician throughout.
