It is the intension of this invention to provide an expandable interbody fusion cage which will expand in all three planes to allow the incorporation of a larger amount of bone graft in the expanded state and facilitate a higher surface area of contact of such bone graft and the fusion cage itself with the vertebral bodies.
#$%^&*AU2014100879A420140911.pdf#####A three dimensional expandable fusion cage for a minimally invasive transforaminal lumbar interbody fusion (TLIF) surgery, said fusion cage comprising a lockable central component allowing for multiplanar expansion as well as allowing bone graft to be incorporated into the cage after the cage has been expanded a free surface area of contact between the bone graft and adjacent vertebral bodies in the expanded state and structural support to the adjacent vertebral bodies to maintain separation at a desired distance. A "TLIF in a box" concept is developed to package a set of instruments and devices for the minimally invasive TLIF surgery including patient specific smart tube retractors for bone graft harvesting and interbody fusion and other patient specific instruments.cic U) (U _0 C-) 0 90 U)) z <0 oz E 0 !
