Oblique Lateral Retroperitoneal Lumbar Pre-Psoas Approach for Vertebrectomy in Cancer Patients: Surgical Technique.

Oblique Lateral Retroperitoneal Lumbar Pre-Psoas Approach for Vertebrectomy in Cancer Patients: Surgical Technique. Surg Technol Int. 2020 Nov 11;37: Authors: Telera S, Raus L, Crispo F, Galarza M, Gazzeri R Abstract Due to the longer survival of cancer patients secondary to improved systemic treatments, there has been a recent increase in the incidence of spinal metastases. Metastatic disease involves the anterior vertebral body in 80% of cases. Progressive osseous invasion may result in pathologic vertebral fractures and neural structure compression. Surgical indications are spinal cord and cauda equina compression or spinal instability in patients with an expected survival of at least 6 months. Tumor resection and spine reconstruction in the lumbar region are technically demanding. Several approaches have recently been developed to access the lumbar spine: anterior lumbar approach (ALIF), lateral and extreme lateral transpsoas lumbar approach (LLIF, XLIF, DLIF), and oblique retroperitoneal lumbar pre-psoas approach (OLIF). Each technique has its advantages and drawbacks. OLIF is an emerging procedure that has progressively been used by spine surgeons. The retroperitoneal space allows direct access to the vertebra, thus avoiding injury to the paraspinal muscles, psoas muscle, and lumbar plexus. Between 2005 and 2017, 14 patients underwent somatectomy and spinal reconstruction using an oblique retroperitoneal lumbar pre-psoas approa...
