One patient in group A. Anterior-only approach was performed in a 40-year-old female with C7-T1 lesion and partial T2 destruction. a, b X-ray demonstrated sagittal instability and kyphosis. A pre-operative sagittal CT (c) and MRI (d) showed significant C7-T1 and partial T2 vertebral bodies’ destruction with mild kyphosis associated with epidural and paravertebral abscess formation, and the cervical spinal cord was severely compressed. A postoperative X-ray (e, f) indicated that the kyphosis got obviously improved; sagittal and coronal CT scan (g, h) showed satisfied focal clearance and decompression without graft and instrumentation-related complications and relapse of Pott’s disease at 12 months of post-operation
