A method and/or apparatus is provided for bone fixation which includes oscillating a wire about a longitudinal axis, advancing the oscillating wire into the bone tissue, and leaving the wire in the bone tissue as a fixation element. The apparatus in the present invention may be a self-contained unit for providing oscillatory motion to a chuck configured for releasably engaging a K-wire or the like, or may include a drive gear for use with a conventional rotor and drill for accomplishing the same oscillatory action.

[ What is claimed is:] [1.] A method of fixating a bone, comprising the steps of:oscillating a fixation wire about its longitudinal axis, said wire having cutting means positioned at a first end of said wire;advancing said fixation wire into said bone during said oscillating step with a force that is comparatively less than would be required for inserting a rotating wire into said bone;Stopping the oscillation of said fixation wire while it is positioned in said bore;leaving said fixation wire in said bone while said bone is healing, said fixation wire requiring on average comparatively more force for removal from said bone during said leaving step than would be required for a wire inserted by rotation.
