Claim:
1. A device for guiding a drilling of a femoral head of a femur in femoral head resurfacing comprising: a body, the body defining at least one guide channel adapted to receive and guide a drilling component therein, the at least one guide channel having a concentric guide direction; arms pivotally connected to the body and biased toward one another about pivot axes being transverse to the concentric guide direction, the arms each having a contact end extending below the body, the contact ends adapted to contact a femoral neck when the body is in a hovering position relative to the femoral head; at least one sensor producing a signal indicative of an orientation angle of each of the arms relative to the body; a processor unit for calculating the orientation angles of the arms from the signal, and for evaluating from the orientation angles an alignment of the body relative to the femur; and a visual output producing a visual signal representative of said alignment.
