External orthopedic fixing apparatus comprises a pair of hexagonal collars (1, 2) connected parallel to each other by means of a pair of adjustable spacers (3) each extending normal to the planes of the collars and connected to opposite sides of each collar; each collar being further provided (in the sides thereof not connected to the adjustable spacing members) with apertures (4) extending transversely of the collar for mounting fixing rods (8) extending between opposite faces of the collar. In one embodiment (as illustrated) the adjustable spacing members take the form of a male member (9) slideable in a longitudinal aperture in a female member (8) each demountably connected, via screw thread rods (6) and nuts (7), to the collars. In another embodiment, the adjustable spacing means take the form of rotatable screw threaded rods connected to one collar and passing through a thread hole in the other collar. <IMAGE> |
