A 59-year-old female who underwent posterior decompression and fusion from C4 to C6 for spinal epidural abscess and osteomyelitis at another facility. (A) She subsequently presented with cervicothoracic junction kyphosis with chin-on-chest deformity. (B, C) Preoperative sagittal computed tomography and magnetic resonance imaging demonstrating a fixed deformity, positive sagittal imbalance, and spinal cord compression secondary to ventral spinal cord compression. The patient underwent a posterior approach for C7 pedicle subtraction osteotomy with posterior segmental instrumentation from C2 to T3. (D, E) Postoperative anteroposterior and lateral radiographs demonstrating posterior instrumented fusion and sagittal deformity correction.
