Abstract
An elbow prosthesis which includes a humeral component having a rod extending along a longitudinal axis and this component further includes a generally cylindrical body having a first articulating surface about which an ulnar component is pivotally mounted so as to pivot about a longitudinal axis of the body. A spacing between a plane extending through the longitudinal axis of the body and the longitudinal of the rod of the humeral component is selected to define a desirable spacing therebetween depending upon a patient's morphology.
Claims9
An elbow prosthesis which takes into account the position of a patients trochlea relative to the patient's humerus, prosthesis including a humeral component having a rod adapted to be inserted into the humerus of the patient and a body having a substantially cylindrical first articulating surface (S1), said rod of said humeral component having a longitudinal axis (X3), an ulnar component having a rod adapted to be inserted into an ulnar of the patient and a member forming a second articulating surface arranged about said first articulating surface of said body so as to pivot about a longitudinal axis (X1) of said body, and means for positioning the longitudinal axis (X1) of said body at a predetermined distance (d′) with respect to the longitudinal axis (X3) of said rod of said humeral component which predetermined distance (d′) is dependent on the patient's morphology and best corresponds to an anatomical position of the patient's trochlea relative to a sagittal plane with respect to a longitudinal axis of the patient's humerus.
