摘要：
Disclosed is a device for assisting in the placement of a trapeziometacarpal prosthesis including a cup to be fixed in the trapezium of a patient and a stem to be fixed in the patient's first metacarpal. The device includes a first guide to be interposed between the trapezium and the first metacarpal, the first guide including a first body having a first surface to be positioned on the articular surface of the trapezium, the first surface congruent with the articular surface of the trapezium and a second surface to face the articular surface of the first metacarpal before resection, the second surface preferably being congruent with the articular surface of the first metacarpal so as to be positionable on the articular surface of the first metacarpal. The first guide also includes locating members carried by the first body and arranged to define resection lines for the first metacarpal.
