RT Journal Article SR Electronic T1 Thoracic disc herniation: An unusual complication after prone positioning in spinal surgery JF International Journal of Spine Surgery JO Int J Spine Surg FD International Society for the Advancement of Spine Surgery SP 39 DO 10.14444/3039 VO 10 A1 Kamat, Ameya S. A1 Ebrahim, Mohammed Zahier A1 Vlok, Adriaan J. YR 2016 UL https://www.ijssurgery.com/content/10/39.abstract AB Neurological complications of the prone position have been well documented. Post-operative paraplegia and neurological deterioration unrelated to the site of surgery after proning in spinal surgery is a rare but potentially devastating complication. We describe the case of a 47 year old female who underwent an L4/5 discectomy and posterior instrumented fusion. A few hours after surgery she developed bilateral lower limb weakness with a T11 sensory level. Post-operative MRI revealed an acute disc herniation at the T11/12 level with associated spinal cord compression. This was not present on the pre-operative imaging. A subsequent T11/12 discectomy and instrumented fusion was performed and the patient's motor and sensory function returned to normal.
