BackgroundRapidly progressing extrinsic spinal cord compression syndromes are rare, especially when the compression is associated with the supine position.PurposeThis work presents a case of extrinsic thoracic spinal cord compression related to the supine position and describes our approach from diagnosis to the technical therapeutic creation of a spinal protection shield.Study DesignOne case of a patient suffering from extrinsic spinal cord compression syndrome is reported.Patient SampleWe report the case of a Coptic priest patient who, as a result of Pott disease sequelae, underwent several decompressive and stabilizing surgeries for major kyphoscoliosis. Consequently, he developed extrinsic thoracic spinal cord compression caused by the supine position.Outcome MeasuresAfter each instrumentation device removal, we noticed progressive severe paraparesis when the patient was supine. Imaging assessment confirmed spinal dynamic and intermittent compressions triggered by the supine position, which was facilitated by the exposure and vulnerability of the thoracic spine cord.MethodsWe implanted a tailored titanium mesh spinal protection shield and a trapezius flap for spine coverage. This work presents the diagnostic aspects as well as several surgical technique options.ResultsAt the 6-year follow-up, the patient's neurologic conditions were significantly improved. We report neurologic improvements, no sphincter disorder, persistent spasticity, and lower limbs weakness not affecting full ambulation.ConclusionsTo our knowledge, no other case of spinal protection shield in compressions caused by the supine position have been studied. The surgical and technical management therefore remains innovative.Copyright © 2015 Elsevier Inc. All rights reserved.
