Above knee prosthesis with PBSS shaft

An interim prosthesis is a temporary prosthesis. In the first few months after a leg amputation, the conditions of the residual limb can still change considerably. The interim prosthesis, also called provisional prosthesis, is used to bridge this phase.

The socket of the interim prosthesis (i.e. the connecting piece between the person and the technology) is not initially made of carbon so that it can be easily adapted to the ever-changing shape of the leg stump during the "trial period". In the case of freshly amputated patients, the circumference of the leg stump is reduced during the first few months. This is due to the healing process of the wound and the reduction of the swelling. In addition, the user can test different fitting parts (e.g. knee joints or different foot parts) during the 6-month interim phase, which are then installed in the final prosthesis. The fit of the prosthesis socket is repeatedly improved by our orthopedic technicians during the interim phase so that as few fitting problems as possible occur with the definitive prosthesis with carbon socket.

How quickly you learn to walk with a prosthesis depends on many different factors. These include, for example

• the wound healing on the residual limb,
• the accuracy of fit of the prosthesis,
• one's own resilience,
• the rehabilitation,
• the muscle building
• etc.

Some users can walk from A to B relatively safely within a few days of receiving their interim prosthesis, while for others this process takes several weeks.
