An elbow arthroplasty system having a ball and a socket. The ball is configured for coupling to at least one member of one of the following groups: (i) a humerus, and (ii) a radius, an ulna, or both of the radius and the ulna. The socket is configured for coupling to at least one member of the other of the following groups: (i) the humerus, and (ii) the radius, the ulna, or both of the radius and the ulna. The socket defines a cavity that is configured to receive at least a portion of the ball. The ball may be a spheroid, an ellipsoid, a sphere, or a portion of one of the foregoing with a convex surface. The socket may be configured with a concave surface that is spheroidal, ellipsoidal, or spherical and designed to mate with the ball. An elbow arthroplasty method using a ball and a socket.

System, apparatus, and method for elbow arthroplasty

The present invention is an apparatus and method for use in a treatment for prevention of arthrofibrosis that includes a first and a second substantially L-shaped frames, each L-shaped frame having a first member and a second member extending from the first member in a substantially perpendicular direction and terminating in a first end, a fixed plate extending between the first members of the L-shaped frames, the fixed plate being parallel with the first members of the L-shaped frames, a movable plate pivotally coupled to the first ends of the first members of the L-shaped frames with, a pneumatic piston coupled to the movable plate and the fixed plate, a hand operated valve operatively coupled to the pneumatic piston and a goniometer coupled to the movable plate and one of the L-shaped frames, the goniometer adapted and configured to indicate the angle between the movable plate and the fixed plate.
