Cervical spondylotic myelopathy and radiculopathy treated by oblique corpectomies without fusion

Oblique corpectomy (OC) is an alternative technique for the resection of spondylotic spurs ventral to the cervical spinal cord contributing to cervical spondylotic myelopathy (CSM) and cervical spondylotic radiculopathy (CSR). To evaluate the efficacy of OC for the treatment of cervical spondylotic myeloradiculopathy, we reviewed our experience with OC. Twenty-six patients, 18 males and 8 females, were studied. They averaged 51.3 years of age (range 30-72), Thirteen had myelopathy and 13, radiculopathy. Both magnetic resonance (MR) imaging and computed tomography (CT) were performed preoperatively to define the extent of pathology. The Modified Japanese Orthopedic Association (JOA) score was used to grade the quality of the outcome. Neurologic and radiologic results were assessed. Good and excellent results were observed in 76.9% of the cases with myelopathy. Improvement of radicular symptoms was noted in 84.6% of the cases with radiculopathy. Neuroimaging studies confirmed satisfactory anatomical decompression in all patients. Sagittal alignment decreased from 13degrees to 12degrees. The degree of postoperative recovery seemed to be directly related to the age and severity of the preoperative myelopathy. This surgical technique has shown excellent clinical outcomes with fast recovery and adequate anatomical decompression in patients with CSM and CSR
