Single-Stage Posterolateral Transpedicular Approach With 360-Degree Stabilization and Vertebrectomy in Primary and Metastatic Tumors of the Spine.

OBJECTIVE

Currently, anterior, posterior, or combined approaches are used in various spinal disorders; however, a single-stage posterolateral transpedicular approach with 360° stabilization and vertebrectomy provides better results for spinal tumors.

METHODS

We evaluated the age, sex distribution, presenting symptoms, neurologic examination findings according to the pre- and postoperative Frankel classification, pre- and postoperative VAS pain scores, preoperatively administered medical therapies, pre- and postoperative corset use, level of the lesion, levels of previous surgical interventions, root ligation (if performed), results of the primary disease, hospitalization duration (after the operation), postoperative complications (if any), postoperative follow-up duration, and postoperative survival duration of 22 patients.

RESULTS

We observed that primary bone tumors were localized in the lumbar (75%) and thoracic regions (25%) and that metastatic tumors were localized in the thoracic (77.78%) and lumbar regions (22.22%). The VAS and Frankel scores of the 22 patients who were included in the study revealed that this surgical treatment modality was associated with statistically significant improvements in test scores (P < 0.001). No ribcage dislocation was observed. In 1 patient (4.54%), a neurologic deficit developed. Two patients (9.09%) required revision because of screw malposition.

CONCLUSIONS

In spinal tumors, 360° fusion performed via a posterolateral approach is a less risky, relatively safe, and less invasive method. This method, which reduces the risks of anesthesia and internal problems and decreases cost, is an essential technique for decreasing hospitalization duration, improving pain levels, and achieving faster mobilization and faster initiation of radiotherapy and chemotherapy.
