Abstract
A device for guiding a drilling of a femoral head of a femur in femoral head resurfacing comprises a body defining a guide channel adapted to receive and guide a drilling component therein. Arms are pivotally connected to the body and biased toward one another, 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. Sensors produce a signal indicative of an orientation angle of each of the arms relative to the body. A processor unit calculates the orientation angles of the arms from the signal, and evaluates from the orientation angles an alignment of the body relative to the femur. A visual output produces a visual signal representative of said alignment. A method for aligning a drill guide device on a femur for subsequent drilling a femoral head with a guide channel in the drill guide device is also provided.
