Abstract

In addition to radiotherapy, the utility of surgical decompression and stabilization in patients with metastatic vertebral body tumors causing cord compression, progressive deformity and/or intractable pain has been well demonstrated. Minimally invasive approaches are an attractive alternative to traditional procedures as they may reduce the degree of disruption of normal anatomy, decrease blood loss, shorten hospital stays and reduce the risk of infection or wound dehiscence. The extreme lateral approach is a procedure that provides access to the anterior spine through a small incision along the flank utilizing a unique retractor system without disruption of posterior vertebral elements, spinal musculature and ligaments. A review of two senior surgeons' databases was performed between June 2010 and October 2014 to identify patients with metastatic vertebral body tumors who were treated surgically at the University of Miami during this period. We report the results of eight cases in which the extreme lateral approach was employed to perform a corpectomy and cage reconstruction for metastatic disease of the thoracic and lumbar vertebral bodies. Each case was supplemented by posterior percutaneous or less commonly open pedicle sc...Continue Reading

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.
