HM3

The new HM3 hip joint for ESSA prostheses offers the usual exact three dimensional adjustment feature, infinitely variable swing phase control, and is light to wear.

With the exchangeable extension stops for 18, 25 and 33° the joint provides for the user’s individual need for safety and improves joint alignment.

Particularly the connection with the ESSA strut (energy-storing, shock-absorbing) leads to better shock absorption due to deformation of the strut at heel strike and energy absorption in the stance phase.

This gives the user a physiological gait which is aided by the artificial hip deformation as the prosthetic leg is lifted at toe-off. This makes it unnecessary to lift the pelvis on the prosthesis side.
