Intravertebral insertion of Interbody fusion cage via transpedicular approach for the treatment of stage III Kümmell disease：a technical note and case presentation

Abstract Background Kümmell disease usually occurs in the elderly osteoporosis population and develops gradually into symptomatic, progressive kyphosis of the spine. Several alternative surgical procedures, including vertebroplasty, kyphoplasty, and osteotomy, can be chose for the treatment of the disease. However, current surgical methods to deal with stage III Kümmell disease are less satisfying. Method A modified technique of intravertebral insertion of interbody fusion cage with posterior spine stabilization was applied to treat stage III Kümmell disease. Results This study details a modified technique applied in a patient with stage III Kümmell disease, showing significant improvement in pain relief, anterior column height recovery, and kyphotic angle correction. And no complications was reported during our follow-up. Conclusions Intravertebral insertion of interbody fusion cage via transpedicular approach provides advantages of acceptable correction of kyphosis, bony fusion, minimal invasion. Thus, our method was a good alternative choice for stage III Kümmell disease.
