Abstract: A prosthetic device comprising mutually engageable male and female components to afford pivotal rotation in a plane, the female component including a socket member having a concave bearing surface with a cross section in said plane substantially in the form of a first circular segment subtending an angle greater than 180*, and a first shaft projecting from the rear of said socket member, and the male component including a head member having a convex bearing surface with a cross section in said plane substantially in the form of a second circular segment of equal radius to said first segment, subtending an angle significantly greater than said first segment, and relieved towards one end over a segmental angle of at least similar order to that by which said first segment exceeds 180*, and a second shaft projecting from the rear of said head member.
