Otto Bock’s Helix3D represents the first innovation in Otto Bock’s portfolio of hip joints in a quarter of a century. The product’s name derives from the unique three-dimensional movement available from the product. This feature mimics the human hip joint’s natural and symmetric gait pattern. Its polycentric design allows for leg length reduction during swing phase which reduces the amputee’s risk of falling and increases function.
Patented Multi-axis Joint Structure
• Produces a three-dimensional hip movement to compensate for pelvic rotation and promotes a symmetrical and natural gait pattern.

• Allows for leg length reduction during the swing phase. This helps reduce the risk of falling and increases security.

• Improves sitting posture and reduces pelvic obliquity to a minimum.

• The Helix
3D‘s large flexion angle makes it easier to accomplish activities of daily living, such as putting on shoes or getting into a car.

Spring and Hydraulics Combination
• It is noticeably easier to initiate swing phase with the hip joint’s integrated expansion springs. Energy stored during the stance phase is used during the swing phase initiation to compensate for the missing or deficient hip muscles and to reduce the amount of energy needed for walking.

• Controls the three-dimensional movement of the hip joint during walking that closely resembles the normal hip movement in the sound leg.

• Allows for a dampened, controlled heel strike in the stance phase with significantly reduced hyperlordosis as well as a natural hip joint extension. Therefore, the user can accomplish a more controlled, smooth roll-over on the prosthesis under full load.

• Allows for an individual stride length setting, which controls the pendulum motion in the swing phase.
