Abstract

INTRODUCTION

At present, the use of a cervical cage has become an accepted and widely practiced surgical intervention for the treatment of cervical disc disease (CDD). Polycarbon Peek cage has been used in cervical disc disease as a spacer, with good longterm outcomes.

METHODS

A retrospective study was performed with 16 consecutive patients who underwent single-level anterior cervical discectomy and fusion (ACDF) with a peek cage. Lateral plain radiographs preoperative, postoperative and after two years taken. Patients were followed for a minimum of 24 month.

RESULTS

The surgical procedures used were technically successful for all patients and there were no major complications related to anesthesia or the overall surgical procedure. The mean intervertebral disc height (DH) preoperative was 4.6 ±1.4 mm and height was 4.5± 1.4 mm at the 24-month follow-up. The mean lordosis angle (LA) was 14.5 ± 16.8 ° preoperatively and 17.5 ±13.5° at the 24-month follow-up.The mean segment angle (SA) was13.4 ±15.2º and 12.6 ±11.9º at the 24 month follow-up. There was no peek cage dislodgment or failure. The clinical symptoms improved in all followed-up patients.

DISCUSSION AND CONCLUSION

ACDF is an effective way for treatment of CDD. Using a cage prevents segmental collaps. This technique can also put AL, SA and SH within normal limits, so postoperative pain reduces and quality of life of the patients. Long-term clinical outcome of the stand-alone cages used in the surgical treatment of one cervical disc disease is satisfactory.
