[The efficacy of allogenic strut bone graft and instrumentation for anterior cervical fusion following subtotal corpectomy and decompression in cervical myelopathy].
OBJECTIVE
To evaluate the efficacy of allogenic strut bone graft and instrumentation for anterior cervical fusion following subtotal corpectomy and decompression in cervical myelopathy.


METHODS
Thirty-five patients with cervical myelopathy were treated by the procedure of allogenic strut bone graft and instrumentation for anterior cervical fusion following subtotal corpectomy and decompression. The preoperative average JOA scale score was 8.7 point (Range 4-15).


RESULTS
Sixty-nine vertebral were corpectomized and 104 levels were decompressed and fused with an average of 3 levels. Among the cases, 1 vertebrae was corpectomized in 7 cases, 2 vertebra in 22 cases, 3 vertebra in 6 cases. There were no surgery-related complications. The patients were followed up from 11-37 months, with an average of 17.4 months. No plate breakage, screw loose, graft infection, lysis and absorption was discovered. The fusion rate was 100%, the average time of fusion was 9.3 months (range from 6-15 months). The postoperative average JOA scale score was 14.8 point (range 7-17), the recovery ratio was 73.5% and the excellent and good results was 82.8%.


CONCLUSIONS
The use of allogenic strut bone graft and instrumentation for anterior cervical fusion following subtotal corpectomy and decompression in cervical myelopathy may not only simplify surgical procedure and decrease injuries and complications, but also the fusion is satisfactory and reliable.
