Helix3D prosthetic hip joint

Functionality

The spring-hydraulics combination

Supports swing initiation by the prosthesis wearer with integrated expansion springs. Energy stored in the stance phase is used to compensate for the missing hip musculature during swing initiation and reduce the energy expended while walking. (Fig. 2)
Controls the 3D movement during the entire gait cycle.
Allows for dampened, controlled heel strike in the stance phase with significantly reduced hyperlordosis as well as smooth extension of the hip joint. Controlled and smooth rollover on the prosthesis under full load becomes possible.
Allows for an individual stride length setting and makes it possible to control the pendulum motion in the swing phase.

Produces a three-dimensional hip movement to compensate for pelvic rotation and promotes a symmetrical and natural gait pattern. (Fig. 1)
Permits shortening of the leg in the swing phase with the objective of reducing the risk of falling, thereby improving functional safety.
Ensures optimal sitting characteristics and reduces pelvic obliquity to a minimum.
Permits a large flexion angle to provide relief in everyday situations such as putting on shoes or getting into a car.
