A method of determining disc space geometry with the use of an expandable trial having endplate-mapping capabilities. An expandable trial is inserted into the disc space and its height is adjusted to obtain the desired decompression and spinal alignment (which is typically confirmed with the use of CT or Fluoroscopic imaging). The endplate dome/geometry dome is then determined by one of the following three methods: a) direct imaging through the trial, b) balloon moldings filled with flowable in-situ fluid (for example, silicon, polyurethane, or PMMA) from superior/inferior endplates or c) light-based imaging through superior & inferior balloons.
An intervertebral trial having a distal end portion having upper and lower surfaces defining a height therebetween, wherein the height is adjustable and is adapted for insertion into a disc space between opposing vertebral endplates, and wherein the distal end portion has a functional feature adapted to map a contour of a vertebral endplate.
A method of manufacturing a patient-specific intravetebral implant for a patient having a disc space defined by a pair of opposed vertebral endplates, comprising the steps of:
A method of building a patient specific intravertebral implant for a patient having a disc space defined by a pair of opposed vertebral endplates, comprising the steps of:
A patient-specific intervertebral fusion cage for insertion into a disc space defined by opposing upper and lower vertebral endplates in a patient, comprising:
