  • Prosthetic hip
    Patent number: 4215441
    Abstract: A prosthesis for replacement of a hip joint is flexion biased so that the prosthetic limb members affixed thereto are urged anteriorly of the body with the prosthetic foot off the ground. Thus, when the prosthetic hip joint is used with the weight activated knee joint, the flexion biasing provides swing phase motion to the leg from energy stored in the biasing member during the stance phase of that leg.
