Delayed Screw Migration Following Anterior Cervical Discectomy and Fusion.

Objective: To identify the clinical and surgical characteristics and treatment options of patients suffering delayed (>1 month) screw back-out after anterior cervical discectomy and fusion (ACDF).

Methods: A systematic review was performed searching Embase, Medline, and Scopus for relevant case studies and case series of delayed screw back-out after ACDF.

Results: A total of 25 studies encompassing 31 patients were identified and included.

Traumatic Central Cord Syndrome.

Central cord syndrome (CCS) is the most common form of incomplete spinal cord injury, with an increasing incidence with the aging population. This is a clinical diagnosis defined by weakness greater in the upper than lower extremities and often prominent sensory complaints in the hands. CCS is typically seen in individuals with underlying cervical canal stenosis from spondylosis who experience sudden forceful movement of the neck, especially hyperextension, resulting in contusion of the spinal cord.

Surgical Management of Thoracic Dorsal Arachnoid Webs: A 10-Year Single-Institution Experience.

Objective: Thoracic dorsal arachnoid webs are intradural membranes that may cause obstruction of cerebrospinal fluid flow and spinal cord compression. Although well recognized, they are rare and there is a paucity of long-term data on their natural history and prognosis. We reviewed radiographic features, surgical indications, and pathologic specimens of patients diagnosed with focal thoracic dorsal arachnoid webs.

Traumatic durotomy and entrapment of neural elements in a lumbar burst and laminar fracture diagnosed on preoperative imaging: illustrative case.

Background: Traumatic dural lacerations can be caused by thoracolumbar burst fractures and, infrequently, can be associated with the entrapment of neural elements within a laminar fracture. The diagnosis of both is difficult to make on preoperative imaging, as the conditions are typically appreciated during surgical exploration. The authors present a case of traumatic durotomy with entrapment of neural elements in a laminar fracture that they believed could be appreciated on preoperative magnetic resonance imaging (MRI).
