Title:
BILATERAL LAMINOPLASTY IMPLANTS
Document Type and Number:
WIPO Patent Application WO2003020143
Kind Code:
B1
Abstract:
Implants (40, 62) for maintaining a distance between cut spinal bones (71, 72) are disclosed. The implants (40, 62) are made of metal, polymer or bone allograft, and have ends (46A, 46B, 63A, 63B) angled with respect to each other to conform to the cut bone ends (71, 72). The implants (1, 62) have hollow regions (49, 70) for packing osteogenic material. The implant ends (46A, 46B, 63A, 63B) have surface projections (56) to reduce slippage. Implants made of bone allograft also have ends made of demineralized bone to speed fusion between spine (71, 72) and implant (40, 62). Methods of using the implants are also disclosed.
