Abstract
AIM: A common complication of cervical laminectomy and fusion with instrumentation is the development of postoperative C5 nerve palsy. The aim of this study was to review the clinical outcome of surgery after cervical laminectomy for cervical spondylotic myelopathy (CSM), and to analyse the role of posterior shift of the spinal cord on the C5 palsy.

MATERIAL and METHODS: The patient population included all patients with CSM who underwent cervical laminectomy and fusion between 2008 and 2015. The demographic, clinical and radiological results of the patients were retrospectively reviewed.

RESULTS: From a total of 75 cases with CSM who underwent cervical laminectomy and fusion using lateral mass screw fixation, C5 palsy developed in 8 (10.7%) cases. Recovery was seen within six months in 7 cases but 1 case with bilateral C5 palsy only improved unilaterally. Postoperative posterior shift of spinal cord (PSSC) was measured as 3.61.6 mm and 5.21.8 mm in cases without and with C5 palsy, respectively (p<0.05).

CONCLUSIONS: It was concluded that there is an increased posterior shift of the spinal cord in cases with C5 palsy, when compared to those without C5 palsy.
