ABSTRACT:
Apparatus is disclosed for producing relief grooves in pan-shaped bones, especially in the acetabulum of a human hip joint. The apparatus includes a drivable drive shaft having a free end section. A casing is arranged on the free end section. The casing has an exterior contour which, facing away from the drive shaft is, at most, as large as the pan-contour of the bone. At least one cutting device is arranged in the casing which is movable transversely relative to the longitudinal axis of the drive shaft. The cutting device has a cutting edge arranged in an outwardly radial direction. An adjusting device is included which cooperates with the cutting device. The cutting edge is arranged in an initial position within the casing and is radially movable outwardly by means of the adjusting device.
