Varos is a prefabricated transfemoral socket from Ottobock. Varos is adjustable for volume changes and allows easy donning and doffing. Varos will fit a large portion of patients mainly with “normal” shaped limbs. it can be tested and fitted fast and easy. We will demonstrate the concept and the fitting procedure during the workshop. Vacuum is the second approach. Since years there is an ongoing discussion about whether to use vacuum fittings in TT applications or not. The trend shows a clear increase. The other part of this workshop helps to understand vacuum in TT solutions. It helps to understand how vacuum is working and what are the benefits for end users and also for CPOs.
