Abstract:
1. An inter-vertebral spondylolithesis reduction spinal insert cage assembly comprising: a first beam having a surface configured for abutting a first opposed surface of a pair of adjacently positioned vertebral bodies; a first perimeter rim coupled to and extending from said first beam, said first perimeter rim having a surface configured for abutting the first opposed surface of the pair of adjacently positioned vertebral bodies; a pair of spaced bars coupled to and extending between said first beam and a distal section of said first perimeter rim relative to said first beam; a threaded drive shaft rotatably coupled to said first beam, said threaded drive shaft extending from said first beam between said spaced bars; a second beam having a surface configured for abutting a second opposed surface of the pair of adjacently positioned vertebral bodies; a second perimeter rim coupled to and extending from said second beam, said second perimeter rim having a surface configured for abutting the second opposed surface of the pair of adjacently positioned vertebral bodies; a pair of sleeves coupled to and extending between said second beam and a distal section of said second perimeter rim relative to said second beam, each of said spaced bars being slidably inserted into an associated one of said sleeves wherein said first beam is slidably coupled to said second beam; at least one bridge coupled to and extending between said sleeves, said bridge having opposite ends being statically coupled to an associated one of said sleeves, said bridge having a medial section engaging said threaded drive shaft wherein said bridge is moved along a length of said shaft when said shaft is rotated; and a pair of connectors, each connector configured to couple an associated one of said first beam and said second beam to an associated one of the vertebral bodies.
