Abstract
There is presented a drill guide assembly for forming a transverse guide hole in a bone, the guide hole being adapted to receive a transverse screw, the guide hole intersecting a tunnel formed in the bone and adapted to receive a body to be retained in the tunnel and to receive the screw transversely of the body to secure the body in the tunnel. The drill guide assembly comprises a track member of an elongated curved configuration, the track member having a bore extending widthwise therethrough, and a curved slide track extending lengthwise thereof, a boom member having a first portion of an elongated curved configuration slidably disposed in the slide track of the track member, and a second portion for retaining a drill bit. The assembly further includes a stem member for disposition in the track member bore, the stem member having an elongated stem portion for extending into the tunnel, and a guide member for attachment to a distal end of the stem portion, the guide member having a recess therein for receiving a distal end of a drill bit retained in the boom member second portion.
