Delayed Neurologic Deficit after Thoracolumbar Kyphosis Correction: One Case Report

Abstract

Study design: Case Report.Objective: To present one case suffering from delayed neurologic deficit after kyphosis deformity correction and analyze its potential etiological factors, how to identify and treat it.Summary of background data: Tardive neurologic deficits occur much less than acute ones after corrections of spinal deformities. Currently some risk factors, such as postoperative hypotension, deformity severity, and intraoperative haemorrhage are considered to be related with its occurrence and worsening though the true mechanisms are not clear. Extrinsic cord compression should be excluded by radiographic examinations before conservative treatments, such as improving blood perfusion, eliminating cord edema, suppressing local inflammation; promoting neurite outgrowth can be applied. If these don't lead to functional recovery of spinal cord, emergency operation returning the cord to its former kyphotic position can also be considered. Methods:This 44 year-old female patient demonstrated thoracolumbar kyphosis of 136.9° combined with incompetence of spinal cord before operation, and underwent posterior vertebra column resection with the kyphotic correction of 68.8°. No neurologic dysfunction was found during operation.
