Objective To describe the configuration of pedicel-ossified ligament flavum tunnel (PFT) and ligament flavum ossification (OLF) in thoracic spine,further to introduce and evaluate the methods of posterior decompression by dissecting pedicle flavum tunnel (PFT). Methods Seventy-four patients were diagnosed as thoracic spine ligament flavum ossification and there were 45 male and 29 female with an average age of 51.9 years (31-73). The CT virtual endoscope (CTVE) and multiplanar co-localization were employed to detect the configuration and connection structures of OLF and to define the construction and the width of PFT.
