Vertebral corpectomy (vertebral body resection), partial or complete, lateral extracavitary approach with decompression of spinal cord and/or nerve root(s) (eg, for tumor or retropulsed bone fragments); thoracic, single segment

Vertebral corpectomy is a surgical procedure that involves the resection of the vertebral body, which is the main part of a vertebra, along with the intervertebral discs located above and below the affected vertebra. This procedure is performed using a lateral extracavitary approach, which allows for optimal access to the spinal structures while minimizing damage to surrounding tissues. The primary indications for this type of surgery include the presence of tumors, retropulsed bone fragments due to fractures, severe spinal stenosis, or infections affecting the vertebral body. In many cases, a collaborative surgical approach may be employed, where a general or thoracic surgeon handles the exposure of the surgical site, and a spine surgeon performs the corpectomy itself. The procedure begins with an incision in the midline of the back, which is then extended laterally to expose the paraspinal muscles. These muscles are carefully elevated to reveal the underlying bony structures, including the spinous processes and laminae. The surgical team may utilize intraoperative imaging to accurately identify the tumor or fracture site, ensuring precise removal of the affected vertebral body and any associated pathological tissues. Following the excision, the surgical site is prepared for potential additional procedures such as bone grafting, spinal fusion, or the placement of internal fixation devices, depending on the specific needs of the patient.
