The 7E9 is a slim, robust hydraulic hip joint that works with a variety of prosthetic knee and foot options. It also has the highest weight limit in its class—275 lbs (125 kg).

7E9 Monocentric Hydraulic prosthetic hip joint is designed for those with hip disarticulation or hemipelvectomy level amputations.

The 7E9 monocentric hydraulic hip joint provides high functionality, safety, and improved mobility for hip disarticulation and hemipelvectomy amputees.

  • Slim, robust design works with a variety of knee and foot options
  • Approved for a maximum body weight of 275 lbs (125 kg), so you can fit a broad range of patients
  • The only hydraulic swing and stance hip approved for use with the 3R60 and 3R106 mechanical knees (can also be used with C-Leg and Genium)
  • Dampened, controlled heel strike; significant reduction of pelvic tilt; smooth, controlled roll-over under full load; support of knee joint stance flexion; and targeted control of the pendulum movements in swing provide a closer approximation to physiological gait.
  • 130° flexion angle and low structural height minimize pelvic obliquity, making sitting more comfortable
  • Easy to align and adjust
  • Recommended for MOBIS mobility grades 2 and 3 (restricted and unrestricted outdoor walkers)
