Somato Prostheses


Frequently asked Questions


  • Of what material are artificial fingers constructed?
  • Artificial fingers are usually constructed using medical grade silicone, which is a soft, pliable, elastic material to closely resemble the skin texture. It is also colored to closely resemble skin color.


  • How is an artificial finger retained in place?
  • In most of the cases, artificial fingers can be retained in place by fitting snugly to the remaining stumps of the missing fingers (just like a glove). Retention problems usually arise when no stumps are available. In those cases retention of fingers can be achieved using medical grade adhesives, which are a medical form of glue. A more advanced method is using osseointegrated implants placed in hand bones, where fingers are attached to titanium screws fixed in the bone. This provides better and more secure retention.


  • Do artificial fingers move?
  • This depends on the level of amputation. For example, if a finger prosthesis is made to replace the tip of a finger or fingers, they can easily move and perform tasks using the residual limb's range of motion. If the fingers are missing completely, then movement is limited.


  • Can the artificial finger have a finger nail that can be painted?
  • Yes, plastic fingernails are attached to artificial fingers. Since they are made of acrylic, fingernails can be shaped and painted like you would with a natural nail. A NON-ACETONE polish remover must be used to remove any nail polish.


  • How long does it take to construct an artificial finger?
  • It takes about 2 weeks.


  • Can the prosthesis be worn all the time?
  • Prostheses can be worn most of the time. However, they should not be worn when bathing, sleeping, or during contact sport activities.


  • How long do prostheses last?
  • Prostheses degrade over time due to several factors. Because of this, they are remade approximately every two to four years. Thin edges of prostheses can tear, color can fade over time, and smoke and chemicals can discolor the silicone material. However, prostheses last longer if they are well cared for and maintained. Implant retained prostheses may have an extended useful life because of the elimination of adhesive products.
