Silicone finger and partial hand prostheses | Ottobock AU
What a silicone prosthesis can do for social integration
It seems strange, but appearance is a function of its own. A hand that you accept optically will not be hidden in your pocket. The realistic-looking restoration of the anatomically accurate shape and colour of your hand helps you feel more confident around people.
The Expanding Options of Partial Hand Prostheses
Passive functional devices include any device designed with static components that have no inherent movement within the device. Silicone restoration prostheses are considered passive functional because they allow the user to support, push, pull, and stabilize objects as well as provide psychological benefits to the user because the device resembles the anatomical details of the missing fingers or hand. Opposition posts are also passive functional devices and allow remnant fingers to oppose against a static armature or platform on the prosthesis. Another option for prosthetic partial hand use is the task-specific device. These devices are designed to help the user participate in a specific activity and can include everything from cutlery and tools, to billiards and fishing. Mechanical fingers have become more advanced in recent years and operate through the harnessing of proximal joints and anatomy. Because mechanical fingers rely on the motion of the user, their use is dependent upon the presentation, strength, and range of motion (ROM) of the wearer. Finally, externally powered partial hand prostheses provide multiarticulating motorized digits that are powered by batteries. These devices provide the highest grasp and pinch forces of the previously mentioned devices and can simulate the pinch and grip patterns of the human hand.
Only when prosthetic design, programming, and training efforts failed to overcome the users’ activity limitations was specific adaptive equipment recommended. For example, trimming finger and toenails was a common activity limitation expressed by the participants that responded best to adaptive equipment. One method of improving independence in nail care was the application of low-temperature plastic to the end of clippers shown in . This modification improved the mechanical advantage of the task and allowed the remaining fingers or prosthetic digits better control of the tool. Another commonly used piece of adaptive equipment was Dycem (Warwick, Rhode Island) to decrease the sliding of objects. Dycem was commonly used under a plate to prevent the plate from sliding while the user was cutting meat.

Properties of silicone
Your prosthesis is made of skin-friendly silicone. Silicone does not cause any allergic reactions. This means that you can wear your silicone finger prosthesis frequently and for long periods. The prosthesis also keeps its shape.

The finger prosthesis thus makes an important contribution to integration in social life and at work. This is why a prosthesis is not just cosmetic; it is an aid for everyday life. It restores the desired appearance of the hand to a certain degree.

What this means for you
The secure hold and good wearer comfort are achieved by the socket of the prosthesis. The socket connects the residual limb and the prosthesis. It is custom fabricated for your residual limb. A firm, direct connection between the prosthesis and your residual limb is created by vacuum. The finger prosthesis adheres firmly to the residual limb in every position and for every grasp movement. Your advantage - you can make precise movements again. In addition, a perfect fit reduces perspiration.

Silicone also looks more realistic. It allows for the finest details of your amputated finger to be replicated for a realistic-looking prosthesis. You can even use nail polish and wear jewellery with a silicone prosthesis. For a comprehensive overview of the design possibilities, see the section
