Lateral lumbar interbody fusion is a minimally invasive approach to anterior spinal column fusion, deformity correction, and indirect decompression of the lumbar spine. A rarely reported possible complication of the procedure is end plate fracture, which has the potential for nerve root compression. Here we present a case of end plate fracture and nerve compression after stand-alone lateral lumbar interbody fusion, its diagnosis, and its subsequent successful treatment with transforaminal endoscopic spine surgery. The case highlights the possible role for minimally invasive endoscopic surgery as a rescue procedure after fusion complication.

Piezosurgery uses microvibrations to selectively cut bone, preserving the adjacent soft tissue. The present study evaluated the use of piezosurgery for bone removal in orbital decompression surgery in Graves disease via a modified pterional approach. ⋯ Piezosurgery proved to be a useful tool in bone removal for orbital decompression in Graves disease. It is safe and easy to perform, without any danger of damage to adjacent tissue because of its selective bone-cutting properties. Nonetheless, further development of the device is necessary to overcome the disadvantages in intraoperative handling and the reduced bone removal rate.

Transforaminal endoscopic lumbar discectomy (TELD), a minimally invasive spinal technique, has advantages over open discectomy. Unilateral TELD for disc herniation causing bilateral symptoms is challenging. In this study, we describe a percutaneous endoscopic herniotomy technique by using a unilateral approach for lumbar disc herniation with bilateral obvious symptoms. ⋯ TELD can be effective for lumbar disc herniation causing bilateral symptoms, through one working channel.

Intramedullary spinal cord abscesses are rarely encountered in modern neurosurgical practice. Select patients are at high risk for developing an intramedullary spinal cord abscess, which can result in acute neurologic deficits. ⋯ The decision was made to perform an urgent cervical laminectomy and drainage to avoid any further decline that may have occurred with continued conservative management. Increased awareness of intramedullary spinal cord abscess is warranted for its clinical suspicion and emergent treatment in select circumstances.

This study aimed to investigate the application of 3-dimensional computed tomography angiography (3D-CTA) for defining cavernous sinus aneurysms and intradural aneurysms involving the internal carotid artery around the anterior clinoid process. ⋯ The virtual line between the inferior border of the anterior clinoid process and the tuberculum sellae on 3D-CTA indicates the proximal dural ring of the internal carotid artery. This line helps differentiate cavernous sinus aneurysms from intradural aneurysms involving the internal carotid artery around the anterior clinoid process.
