    摘要: A spine implant system having two or more adjacent segments that have a male-female annular interlocking relationship for increased mechanical stability and resistance to relative translation and rotation. One or more segments is provided with at least one perforation channel or void to promote osteo-induction within the segment. Optionally, two adjacent segments have at least one common or aligned perforation channel or void. Two or more spaced apart portions of a segment surface are optionally chamfered to provide easier fabrication and/or positioning of the segment. Two spaced apart exposed surface planes of an interlocked segment pair optionally are axially oriented at a small positive angle relative to each other, to approximate natural spine curvature. Segments in some embodiments have a curvilinear delta cross sectional shape and/or have crosshatched grooves in exposed surfaces. Many of the embodiments are useful in transforaminal lumbar interbody fusion (TLIF).

    摘要: A spinal implant includes a bone implant body having a superior end face, an inferior end face, and an outer sidewall extending between each end face. There are at least two flat sidewall portions on the outer sidewall to enhance the gripping of a gripping instrument. In a first embodiment, the two flat sidewall portions each have a pin insertion hole, the holes being offset at about a 30 degree angle from each other. In a second embodiment, concentric cuts are included on the superior and inferior end faces. In a third embodiment, radial cuts are included on the superior and inferior end faces. In a fourth embodiment, at least one pin hole on the flat sidewall portions includes stress relief means. Three methods are disclosed of forming an implant by (1) cutting concentric cuts, (2) cutting radial cuts, and (3) cutting both concentric cuts and cutting radial cuts on the superior and inferior end faces.
