MODULAR INTERBODY FUSION IMPLANT

摘要

An interbody fusion device (10) for engagement between vertebrae includes a pair of lateral spacers (12, 13) for spacing the vertebrae, and a connecting member (28) adapted to couple together the lateral spacers (12, 13) when inserted between the vertebrae. The connecting member (28), individual later al spacers (12, 13), or the entire spinal spacer (10) can be made of bone in order to promote fusion of the vertebrae. The modular construction permits u se of bone segments otherwise unsuitable due to size or strength in stable fusi on devices.
