| Popis: | Introduction: It is generally accepted that laminoplasty is a safe and reliable surgical treatment for cervical spine myelopathy (CSM) due to spinal canal stenosis. There are multiple techniques of laminoplasty for spinal cord decompression and most of them require expensive instruments to stabilize the laminae. From 2005 to 2015, we applied the modified Z-plasty (Sakou's technique) for CSM patients in an attempt to reduce the cost of treatment. Materials and methods: This is a retrospective study. CSM patients treated by modified Z-plasty technique were selected. We applied the Sakou’s technique, according to which the laminae will be opened in different directions alternatively. We use the JOA score and recovery rate of Hirabayashi to assess the neurological recovery and the Neck Disability Index (NDI) for the cervical functional outcome. Results: There were 42 patients with the mean follow-up duration of 10 years (5-15 years), male: female ratio of 3:1 and mean age of 61. The mean operating time and blood loss per lamina were 40 minutes and 45ml, respectively. The canal expanding index was 4.2mm (3-5 mm). The mean pre- and postoperative JOA score were 11.1 and 14.7, respectively (p |
