The unilateral joint system
Orthosis joints for leg muscle paralysis
Optimised, harmonised system
The unilateral joint system from Ottobock provides you with a modern, harmonised and integrated leg orthosis fitting in case of paresis or paralysis of the leg musculature. It consists of a knee joint and ankle joint.
Depending on your individual physical condition, the unilateral joint system makes it possible to use only one knee and ankle joint respectively. This makes the orthosis especially light and comfortable to wear.
The ankle joint has a foot lifting effect and can be individually adapted to your needs by your orthopaedic technician thanks to its numerous adjustment possibilities.
Your technician can also equip the knee joint with an additional switch, so that you can set it to an open position for a limited time, for example to train on a therapy bike.
Your orthopaedic technician can install the switch in the knee joint if required. When you set the knee joint to an open position for a limited time, you can for example ride a therapy bike.
Multifunction ankle joint
The ankle joint has a foot lifting effect and can be individually adapted to your needs thanks to its various adjustment possibilities.
The lock lever makes it quick and easy to release and lock the joint with only one hand. A pull-release cable for unlocking can be installed if required.
Benefits at a glance
Comfortable to wear
With a body weight of up to 110 kg and depending on your physical condition, it is possible to only use one instead of two knee and ankle joints respectively. This makes the orthosis especially light, slim and comfortable to wear.
Titanium: particularly lightweight
The joint system is also available in an ultra-lightweight titanium version.
Always the right size
The joint system is available in different sizes, including size versions especially for children.
The unilateral joint system consists of a locked knee joint with wedge lock and a multifunction ankle joint. While the knee joint is permanently locked, it can be unlocked using a lock lever or pull cable, for example when you want to sit down. The joint engages automatically when you get up and is therefore locked again.
The ankle joint has a foot lifting effect and, with nine different possible combinations of spring, stop and spring stop as well as the continuously variable limitation of the range of motion up to a maximum of 20°, makes it possible for your orthopaedic technician to adjust the joint to your individual needs.
