[Retracted] Detection and Analysis of Perfusion Pressure through Measuring Oxygen Saturation and Requirement of Dural Incision Decompression after Laminectomy

Figure 3

(a) An old male admitted to hospital for “head injured by a heavy object” (ASIA grade A) (diagnosis: spinal cord injury and cervical spine fracture). (b) Oxygen saturation probe was inserted after C2–C6 lamina decompression and internal fixation. (c) Spinal blood oxygen saturation was in a normal range (68.3%). Postoperative ASIA grade improved to grade D.
