Abstract

An expandable intervertebral implant (10) includes superior (20) and inferior (30) bone contacting members and at least one vertical wire netting (50) interconnecting the superior and inferior bone contacting members. The superior and inferior bone contacting members include at least two bone contacting components interconnected via one or more lateral wire nettings such that the implant is vertically and laterally expandable in situ from a first insertion configuration to a second expanded configuration. The vertical and lateral wire netting are preferably constructed of a plurality of individual link members. The present invention also preferably relates to an associated method of manufacturing the intervertebral implant such that the intervertebral implant can be manufactured as an integral component or part.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 021778, filed January 17, 2008, entitled "INTERVERTEBRALSPACE AUGMENTATION," the contents of which are incorporated herein in their entirety reference. Background technique [0003] People (especially older adults) can suffer from osteoporosis. One aspect of osteoporosis can be partial or complete shrinkage of the bony structure of the spine, which in turn can cause loss of spinal height, disc fractures, bony planes and nerve impingement, among others. Constriction of the spine often results in, for example, pain, reduced lung function, unbalanced posture, and the like. One treatment option may be surgical treatment to realign the spine (eg, re-establish the balanced curvature of the spine and intervertebral disc spaces). [0004] Realignment of the spine including damaged vertebrae or discs may be achieved by replacing the damaged vertebra...
