NCT02485574

Brief Summary

The purpose of this study is to evaluation for the pattern of bone bridging of patients who undergo transforaminal lumbar interbody arthrodesis, the investigators hypothesize that auto local bone mixed with β-calcium phosphate + hydroxyapatite (OSTEON 2, Genoss) is not inferior to auto local bone only. In addition, the investigators will analyze anterior new bone bridging pattern between anterior bridging cage newly developed and grafted bone in anterior disc space.

Outcome Measures

Primary Outcomes (1)

  • InCBB of Both Cages

    We used the concept of InCBB (intra-cage bridging bone) to evaluate the fusion status. InCBB was defined as the bridging bone between the upper and lower vertebrae through the void of the cage(s) and divided into right (Rt.) and left (Lt.) InCBB according to the cage position. We graded bridging scores from 0 to 2 based on the degree of completion of the bridging bone in InCBBs (grade 0: no bridging at the superior and inferior endplates; grade 1: incomplete bridging; bridging at the superior or inferior endplate, but with a clear radiolucent line; grade 2: complete bridging).

    12 month postoperatively

Secondary Outcomes (1)

  • ABB (Anterior Bone Bridging) Between Cage and Anterior Grafted Bone

    12 month postoperatively

Other Outcomes (1)

  • ODI Change (Preoperative ODI Score - Postoperative 1 Year ODI Score)

    postoperative 1 year

Study Arms (2)

Left cage- auto bone

EXPERIMENTAL

At the operated segment, left cage was filled with auto bone only. We evaluated bone bridging between inside and outside the cage in transforaminal lumbar interbody arthrodesis.

Procedure: transforaminal lumbar interbody arthrodesis

Right cage- auto local bone mixed with β-calcium phosphate + hydroxyapatite

EXPERIMENTAL

At the operated segment, right cage was filled with auto local bone mixed with β-calcium phosphate + hydroxyapatite. We evaluated bone bridging between inside and outside the cage in transforaminal lumbar interbody arthrodesis.

Procedure: transforaminal lumbar interbody arthrodesis

Interventions

Anterior bridging cages augmented with auto bone plus β-calcium phosphate + hydroxyapatite in right side of disc space and anterior bridging cages augmented with auto bone in left side of disc space in transforaminal lumbar interbody arthrodesis.

Also known as: β-calcium phosphate + hydroxyapatite (OSTEON 2, Genoss), Auto-local bone
