摘要:
A surgical instrument assembly for use during a surgical procedure to implant a humeral component without a stem to replace the humeral head of the humerus (400) of a patient, comprising: a sizing instrument (160) having a size that mimics the size of the humeral component without stem to be implanted to replace the humeral head of the patient's humerus, the sizing instrument having a generally round body (162) with a plurality of drill guide holes (170) formed therein, where each of the plurality of drill guide holes is positioned at a location that (a) is located on the spongy bone tissue of the patient's humerus when the sizing instrument is secured to the patient's humerus, and (b) is aligned with a plurality of legs (16) of the rodless humeral component, characterized in that the generally round body of the Sizing instrument is generally dome-shaped having a flattened upper surface (164) and a flat opposite lower surface (166), and an elongated drilling guide bore (168) extending through a center of the sizing instrument from the flattened top surface to the bottom surface, and the drill guide hole is positioned at a location to mate with the spongy bone tissue of the patient's humerus when the sizing instrument is secured to the patient's humerus, the surgical instrument assembly further comprising: a test head component (210), in which: the test head component comprises (i) a generally hemispherical test support surface (212), (ii) a lower surface (220) opposite to the test support surface, where the diameter of the lower surface of the test head component is substantially the same as was the diameter of the sizing instrument, and (iii) a central lug (218) extending laterally away from the bottom surface, the central lug being configured to be frictionically secured to the sizing instrument when the central lug is inserted into the elongated drilling guide drill.Un montaje de instrumento quirúrgico para su uso durante un procedimiento quirúrgico para implanta
