摘要： A surgical implant for spinal fixation formed by a rigid bent titanium frame having wire receiving means. Spinal fixation implants are used to correct abnormal curvature of, and/or impart stability to, the spine by immobilising a plurality of vertebrae with respect to each other. A rigid bullet shaped frame which fits neatly onto the posterior surface of the spine to embrace at least two bones is fixed in place by means of fixation wires passed around or looped through the frame and passing through holes in the bones to immobilise the embraced bones with respect to each other. The frame has a substantially rectangular cross-section. An improved surgical implant results from the provision of wire receiving means which prevent the fixation wires moving relative to the frame and the bullet shaped frame of rectangular cross-section which improves the stability of a fixed implant by close conformity of the implant to the shape of the spine.
