Bioactive spinal implants and method of manufacture thereof

摘要

A bioactive spinal implant used in cervical fusion, Anterior Lumbar Interbody Fusion (ALIF), Posterior Lumbar Interbody Fusion (PLIF), and Transforaminal Interbody Fusion (TLIF), having properties and geometries that enhance bone contact, stability, and fusion between adjacent vertebral bodies.

主权项

1. A spinal implant comprising:
a body comprising a bioactive substance, further comprising: an anterior side and a posterior side opposing the anterior side; a medial side and a lateral side with one side being outwardly curved and the other being inwardly curved; a top surface and a bottom surface, each of the top and bottom surfaces including plural projections for enhancing interaction with a synthetic or natural vertebral body; a major recess formed in the body creating a longitudinal through-aperture in communication with the top and bottom surfaces, at least one minor recess formed in the body creating a latitudinal through-aperture in communication with the medial and lateral sides, both through apertures in communication with each other; and a handling feature comprising a pair of anterior recesses formed at points where the anterior side communicates with the medial and lateral sides, said recesses used for receiving a manipulator, a pair of posterior recess formed at points where the posterior side communicates with the medial and lateral sides, and a front recess formed in the anterior side and a rear recess formed in the posterior side both communicating with a through-aperture, the handling feature facilitating handling and insertion of the spinal implant into an intervertebral space.
