[Anterior cervical decompression and fusion by microscope for the treatment of cervical spondylotic myelopathy].

OBJECTIVE

To explore clinical effects of anterior cervical decompression and fusion by microscope in treating cervical spondylotic myelopathy.

METHODS

From February 2005 to March 2010,21 patients with cervical spondylotic myelopathy, 13 males and 8 females with an average age of 51.5 years (ranged, 32 to 71), were treated with anterior cervical decompression using high-speed bur,then bone grafting and fusion with auto iliac bone and internal fixation by microscope. According to JOA score of cervical spondylosis to evaluate clinical effects before and after operation.

RESULTS

All patients were followed up from 18 to 24 months with an average of 20 months. JOA score improved significantly from preoperative 9.26 +/- 1.72 to postoperative 13.64 +/- 1.38 (t = 2.452, P = 0.000). According to JOA score, 12 cases were excellent, 7 good and 2 fair.

CONCLUSION

Anterior cervical decompression and fusion by microscope is a refined, safe and effective surgical procedure for cervical spondylotic myelopathy.
