The authors describe the surgical technique of en bloc resection of musculoskeletal neoplasms that originate and invade the posterior arch of the thoracolumbar spine. Surgery is indicated for the treatment of aggressive benign tumors (Enneking stage 3) and malignant tumors. For surgical margins to be adequate, both pedicles must be free of the tumor.

Lateral retrovascular approach to the upper cervical spine.

The authors describe the surgical anatomy of lateral approach to the upper cervical spine. The approach is retrovascular retropharyngeal extraoral allowing for anterolateral exposure of the upper cervical column, and it may be enlarged posteriorly on the homolateral posterior hemiarch of C1 and C2, and/or inferiorly on the lower cervical column. Absolute indications to this approach are anterolateral fusion with transarticular screws C1-C2 and excision of skeletal neoplasms adjacent to the vertebral artery. For other indications such as the treatment of anterior neoplasms and spinal cord decompression it is preferable to use pre-vascular extraoral approach or transoral approach.

Surgical technique: dorsal vertebral hemiresection for bone tumors.

The authors describe the technique of sagittal vertebral hemiresection used for the treatment of tumors of the thoracic spine involving one or more hemivertebrae. This type of treatment is not frequently indicated because of the rare asymmetrical distribution of vertebral tumors.

Lumbar vertebrectomy for the treatment of bone tumors: surgical technique.

The authors describe lumbar vertebral resection for the treatment of bone tumors by double approach (posterior longitudinal with the patient in prone position, and retroperitoneal lobotomy in lateral position), usually performed in one-stage surgery. The indication includes aggressive benign tumors (e.g., stage 3 giant cell tumor, osteoblastoma) and low-grade malignant tumors (e.g., chordoma, chondrosarcoma). In these cases an oncologically adequate surgical margin may be obtained, provided that the neoplasm is entirely or largely intracompartmental and at least one of the vertebral pedicles is uninvolved. The different stages of surgery and anesthesia-related problems are described, and possible complications are discussed.
