Hip joint Helix3D

New fitting standards

Benefits at a glance

Individual stride length

Your individual normal stride length can be taken into account by your orthopaedic technician with the pre-configuration of the hydraulic unit.

Various walking speeds

Are you in a hurry or taking a relaxed walk? You determine the speed and the Helix3D hip joint adapts.

Large flexion angle

A large flexion angle offers relief in many everyday situations such as sitting, putting on shoes or getting into a vehicle. The joint does not protrude below the pelvic socket while seated, promoting a comfortable sitting position.

More natural gait with relief for the sound side

In order to initiate hip flexion for the next step, amputees with conventional hip joint fittings need to raise the prosthetic leg high by lifting the heel of the sound side, and have to tilt the pelvis unnaturally. Both can be greatly reduced with the Helix3D hip joint system.

Harmonious gait pattern

The unique hydraulic hip extension control system protects the locomotor system against impacts. The movement pattern is much more physiological, saving energy and resulting in a very natural gait pattern. This also relieves the back and joints, and prevents subsequent problems.

Walking down stairs step-over-step

For a fitting that is harmonised in terms of safety, functionality and comfort, Ottobock only approves the combination of the microprocessor-controlled C-Leg or Genium knee joint and the Helix3D. This even makes it possible for you to master stairs and overcome other small obstacles. You gain safety and dynamics.



The patented, multi-axis joint structure of the Helix 3D results in a three-dimensional movement of the hip, thereby compensating for the natural rotation of the pelvis. The result is a symmetrical and natural gait pattern. You enjoy sufficient flexion and are able to sit in comfort, since the pelvic tilt is reduced to a minimum.

A novel spring-hydraulics combination makes it easier to initiate the swing phase. You can use energy stored in the stance phase in order to initiate the swing phase. This compensates for the missing hip musculature, allowing you to walk with reduced effort. Stepping down in the stance phase is dampened and controlled, and the hip joint is extended harmoniously. Controlled and smooth rollover on the prosthesis under full load becomes possible as a result. The spring-hydraulics combination also allows for an individual stride length setting, and makes it possible to control the pendulum motion in the swing phase.

Prosthesis training

After your fitting with the Helix 3D hip joint system in combination with the Genium or C-Leg, it is important for you to practice handling your new prosthesis. Your orthopaedic technician will provide you with detailed instructions and recommendations in conjunction with a therapist with special training. You practice negotiating slopes and ramps, sitting and crossing obstacles, and you perform your training with the most physiological gait possible that conserves energy. In doing so, you establish the conditions for the best possible use of your prosthesis in everyday life.

Ideal prosthesis components

Ottobock only approves a fitting with the Helix 3D hip joint in combination with the microprocessor-controlled C-Leg or Genium knee joints. These intelligent systems adapt to a wide variety of everyday situations, and provide you with the essential confidence that you can fully rely on your prosthesis.


Integrated sensors in the Genium continuously monitor the user's current gait phase. With the Genium you experience a noticeable reduction in the energy and coordination effort you have to expend, especially on slopes, inclines or uneven surfaces. Highlights of the Genium include the ability for transfemoral and knee disarticulation amputees to climb stairs step-over-step for the first time –without an active drive system or massive compensating movements. Curbs, obstacles in the household or other everyday tripping hazards can also be handled more safely and naturally.


In 1997, Ottobock brings the C-Leg to market as the world's first fully microprocessor-controlled leg prosthesis system. The proven C-Leg technology sets standards to this day. A complex sensor system regulates the knee joint, permanently recognising your current phase in the gait cycle. Walking slow or fast, stability even in uncertain situations and on rough terrain, negotiating slopes and walking down stairs step-over-step: the C-Leg makes such everyday freedom of movement possible for you.
