A dynamic fixation medical implant having at least two bone anchors includes a longitudinal connecting member assembly having an elongate core and an outer sleeve. The core may be substantially cylindrical, of one-piece construction, and includes end portions for attachment to the bone anchors. A portion of the core extending between the bone anchors has at least one slit. The outer sleeve may include compression grooves. The sleeve surrounds the core and extends between the pair of bone anchors, the sleeve being compressible in a longitudinal direction between the bone anchors.

1. A longitudinal connecting member for a medical implant assembly having multiple bone attachment structures, including a first and a second bone attachment structure, the longitudinal connecting member comprising: a) an inner core having a outer surface and a slit being defined by a slit length and formed on the outer surface about a mid-portion of the inner core, the core being integral along a substantial length of the connecting member and being adapted to be secured between the first and second bone attachment structures; andb) an elastically compressible outer sleeve adapted for compressive engagement with a side surface of the first attachment structure, and completely covering the inner core in both flexion and extension, the sleeve being located outside of the inner core outer surface, so as to allow freedom of movement between the inner core and the outer sleeve respectively, the sleeve being adapted to be positioned entirely between the first and second bone attachment structures so as to be axially compressed with movement of the first and second bone attachment structures, so as to provide a dynamic tension-compression relationship between the axially compressed sleeve and the inner core slitted portion. 2. The connecting member according to claim 1 in combination with the first and second bone attachment structures. 3. The connecting member according to claim 1 in combination with the first and second bone attachment structures and positioned and configured therebetween such that movement of the first and second bone attachment structures toward one another at least partially compresses the connecting member. 4. The connecting member according to claim 1, where the slit is formed in a helical pattern. 5. The connecting member according to claim 1, wherein the slit further includes a central bore that extends along the slit length and along a central axis running parallel to the connecting member. 6. A longitudinal connecting member for a medical implant assembly having multiple bone attachment structures, including a first and a second bone attachment structure, the longitudinal connecting member comprising: a) an inner core having a periphery and a slit being defined by a length and formed on the periphery about a mid-portion of the core, the core being integral along a substantial length of the connecting member and being adapted to be secured between the first and second bone attachment structures; andb) an elastically compressible outer sleeve adapted for compressive engagement with a side surface of the first attachment structure, the sleeve completely covering an entire length of the inner core in both flexion and extension, the sleeve being located outside of the inner core periphery, so as to allow freedom of movement between the inner core and the outer sleeve respectively, the sleeve being adapted to be positioned entirely between the first and second bone attachment structures involving extension and compression. 7. The connecting member according to claim 6, where the slit is formed in a helical pattern. 8. The connecting member according to claim 6, wherein the slit further includes a central bore that extends along the slit length and along a central axis running parallel to the connecting member. 9. A longitudinal connecting member for a medical implant assembly having multiple bone attachment structures, including a first and a second bone attachment structure, the improvement comprising: a) an inner core having a outer surface and a slit being defined by a slit length and formed on the outer surface about a mid-portion of the inner core, the core being integral along a substantial length of the connecting member and being adapted to be secured between the first and second bone attachment structures; andb) an elastically compressible outer sleeve adapted for compressive engagement with a side surface of the first attachment structure, and covering the slit of the inner core, the sleeve being located outside of the inner core outer surface, so as to allow freedom of movement between the inner core and the outer sleeve respectively, the sleeve being adapted to be positioned entirely between the first and second bone attachment structures so as to be axially compressed with movement of the first and second bone attachment structures, so as to provide a dynamic tension-compression relationship between the axially compressed sleeve and the inner core slitted portion.
