Abstract:

Objective To evaluate the clinical outcome of expansive open-door laminoplasty using Centerpiece Titanium Miniplate internal fixation. Methods 14 cases with cervical spondylotic myelopathy(CSM) underwent expansive open-door laminoplasty, and CenterpieceTM plate internal fixation in C3, C5 and C7 segments. Neurological deficits pre- and post- operation were assessed using a scoring system proposed by Japanese Orthopaedic Association (JOA score). Results The period of follow-up lasted from 6 months to 2 years with a mean of 13.6 months. The JOA score were improved from 11.1 points pre-operation to 15.3 points at the latest follow-up(P<0.05). Reclosed open-door was not found. There were 2 cases had slight axial symptoms like neck pain and neck movement two months after the operation, and released when six months follow-up. Conclusions Expansive open-door laminoplasty is a reliable procedure for CSM. Centerpiece TM plate internal fixation may be an effective measure to prevent reclosed open-door and postoperative axial syndromes.
