Utilizing vertebral body autograft for anterior cervical corpectomy/fusion.

BACKGROUND

There are numerous ways to reconstruct cervical vertebral bodies and achieve arthrodesis following anterior cervical corpectomy and fusion (ACF). However, device and donor site complications abound. Here, we describe a novel technique for performing ACF using the vertebral body itself as a structural autograft.

METHODS

The anterior cervical spine was accessed and discectomies were performed rostral and caudal to the corpectomy. Five millimeter troughs were drilled on the lateral borders of the vertebral body, and it was removed . The autograft was rotated 90°, and an anterior cervical plate was selected to span the length of the graft, allowing for fixation to the adjacent vertebral bodies. The plate was secured to the graft, the graft was placed in the bony defect, and the plate was secured to the adjacent levels.

RESULTS

This corpectomy reconstructive technique was successfully applied in a 57-year-old female with cervical myelopathy due to a C5-C6 disc herniation with caudal migration. The C6 vertebral body was used as a structural autograft. Postoperatively, the patient experienced satisfactory improvement in her myelopathy, and the construct appeared stable 8 months later.

CONCLUSION

This corpectomy reconstructive technique takes advantage of the favorable osteogenic properties of autograft, while avoiding donor site morbidity as well as the cost and complications of other devices, such as cages. Further cases are required to verify the safety, efficacy, and biomechanical stability of this technique.
