Abstract
A spinal fixation plate has inner and outer surfaces through which a pair of adjacent screw holes extend along generally parallel axii. The screw holes accommodate the heads of conventional bone screws while allowing the threaded shafts of the screws to pass therethrough. A recess extends into each screw hole for receiving a V-shaped latch having a pair of wings joined to a head via elastically deformable arms. The latch is moveable between a deployed position in which the wings extend into the screw holes to prevent a screw seated therein from backing out and a retracted position in which the wings arc retracted from the screw holes enabling the screws to be backed out of the plate.
