Surgical implant
First Claim
1. A radiopaque intervertebral metal implant for fusion of two bridged vertebral bodies comprising:
- an upper plane for contacting an upper vertebral body;
a lower plane for contacting a lower vertebral body;
a tubular structure formed by a plurality of tubes for the fusion of the two bridged vertebral bodies, the plurality of tubes comprises vertical tubes and horizontal tubes, wherein the vertical tubes run from the upper plane to the lower plane and the horizontal tubes run in a substantially horizontal direction throughout one side of the intervertebral implant straight to the opposite side of the intervertebral implant thereby interconnecting the vertical tubes;
the horizontal tubes of the tubular structure are parallel to each other or are grouped into groups of parallel horizontal tubes so that X-ray spectra or radiographs are conductable through the horizontal tubes, and wherein all surfaces of the intervertebral metal implant have a roughness of 6.0 Ra to 8.5 Ra.

Abstract
The present invention is directed to a surgical implant for the fusion of two adjacent vertebrae with an upper plane for contacting an upper vertebral body and a lower plane for contacting a lower vertebral body and a tubular structure, wherein the tubular structure is formed by a plurality of tubes running from the upper plane to the lower plane and in substantially horizontal direction throughout one side of the surgical implant straight to the opposite side of the surgical implant. This tubular structure has the advantage that the formation and ingrowth of new bone is promoted and advantaged and that the degree of formation and ingrowth of new bone is detectable by X-ray measurements.

17. A radiopaque intervertebral metal implant for fusion of two bridged vertebral bodies comprises:
-
an upper plane for contacting an upper vertebral body; a lower plane for contacting a lower vertebral body; at least one cavity in the center of the implant extending from the upper plane to the lower plane, wherein the at least one cavity is surrounded by a boundary layer with a tubular structure comprising vertical tubes and horizontal tubes; wherein the vertical tubes run from the upper plane to the lower plane; and the horizontal tubes run in a substantially horizontal direction throughout one side of the intervertebral implant straight to the opposite side of the intervertebral implant thereby interconnecting the vertical tubes, the horizontal tubes are parallel to each other or are grouped into groups of parallel horizontal tubes so that X-ray spectra or radiographs are conductable through the horizontal tubes, and wherein all surfaces of the intervertebral metal implant have a roughness of 6.0 Ra to 8.5 Ra. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
