Early changes in the operated and adjacent segments after anterior cervical microdiscectomy and interbody fusion with poly one (PEEK) cage containing synthetic bone particulate: A prospective study of 20 cases [Anteriror servikal mikrodiskektomi ve sentetik kemik partikülü İçeren polietereterketon (PEEK) cage ile İnterbody füzyon uygulamasi{dotless}nda opere segmentte ve komşu segmenttlerde erken dönem deǧişiklikler: 20 olguluk prospektif çali{dotless}şma]

Objective: to evaluate the effects of implantation of peek cage containing synthetic bone particulate on the height and cross-sectional area of the foramen,the intervertebral disc height and the degree of lordosis in the treatment of cervical disc disease. methods: twenty patients,with cervical disc herniation were operated a standard cervical microdiscectomy. the heights of the intervertebral discs,cross-sectional areas and heights of neural foramen bilaterally in the affected level and in the upper and lower adjacent levels were calculated. results: there were no implant related complications or additional surgeries required for any cause. there were significant decrease in vas scores of patients between the preoperative time and the postoperative follow-ups. the radiological outcomes showed that,there were significant increase in the height of the intervertebral disc,the cross sectional areas and heights of bilateral neural foramen at the operated level,between the preoperative time and the postoperative follow-ups. however,there was not statistically significant radiological change at the upper and lower adjacent levels between the preoperative time and the postoperative follow-ups. conclusions: the use of peek cage in the acdf had obvious positive effects on the disc heights and neural foramina at the operated level. however,no negative effects at the adjacent levels were determined.
