Background: Spondylotic cervical myelopathy is defined as spinal cord dysfunction secondary to extrinsic compression of the spinal cord and/or its vascular supply so it is the commonest cause of cord dysfunction in patients over 55 years. Main Surgery target is to prevent the progression of symptoms also to improve existing symptoms.
Aim of the work: To determine prognostic factors of patients with spondylotic cervical myelopathy that surgically managed through anterior approach in relation to outcome clinically and radiologically.
Patients and methods: From July 2015 till December 2018, forty patients with cervical myelopathy were operated by anterior surgical approach (anterior cervical discectomy with fusion and/or corpectomy with fusion. Only patients with confirmed spondylotic myelopathy were included; we exclude those with an infectious, inflammatory or neoplastic etiology.
Results: Patients ages were ranged from (40-67) years, with a mean age 53.2 years. Duration of myelopathy ranged from 2-18 months with a mean duration of 8.55 months. 72.5% patients were treated by discectomy with fusion and 27.5%cases were treated by combined discectomy and corpectomy with fusion. Excellent outcome was reported in 22.5%, while 62.5% cases had good outcome,15% patients had fair outcome. Patient age, disease severity, duration, bowel & bladder manifestations and affection of dorsa column were the prognostic factors in studied patients.
Conclusion: Our study reveals that the significant prognostic factors are: age of patient, severity of myelopathy, duration of myelopathy, presence of bowel or bladder symptoms, dorsal column affection and high signal intensity of T2 weighted MRI.
