Modified K Line in MRI is a Powerful Tool to Predict Clinical Outcomes in Patients with Non-Lordotic Alignment after Laminoplasty for a Treatment of Cervical Spondylotic Myelopathy

چکیده
Introduction: We have previously reported the modified K-line (mK-line), which was defined as a line connecting the midpoints of the spinal cord at C2 and C7 on T1 weighted sagittal MRI, can predict postoperative insufficient decompression in patients with cervical spondylotic myelopathy (CSM) who underwent laminoplasty. Although it is very important for spine surgeons to predict postoperative clinical outcomes, particularly in patients with cervical malaligment such as kyphotic or sigmoid alignment, before selecting a surgical procedure for the treatment of CSM, few studies thus far has assessed a relationship between postoperative outcomes and anticipated spinal cord shifting quantified on MRI. The purpose of this study is to investigate whether mK-line can be a powerful tool to predict postoperative clinical outcomes in patients with non-lordotic alignment.

Laminoplasty with lateral mass screw fixation for cervical spondylotic myelopathy in patients with athetoid cerebral palsy
Although several studies report various treatment solutions for cervical spondylotic myelopathy in patients with athetoid cerebral palsy, long-term follow-up studies are very rare. None of the reported treatment solutions represent a gold standard for this disease owing to the small number of cases and lack of long-term follow-up. This study aimed to evaluate the outcomes of laminoplasty with l...
متن کاملClinical outcomes following cervical laminoplasty for 204 patients with cervical spondylotic myelopathy.
BACKGROUND Laminoplasty is a well-recognized technique for decompressing the cervical spine in cases of spondylotic myelopathy and ossification of the posterior longitudinal ligament. This technique, originally popularized in Asia, is becoming more widespread, but to date there have been few reports of clinical series from North American centers. METHODS Retrospectively we reviewed (1986-2001...

متن کاملClinical results of the new cervico-thoracic orthosis 'Neck-Chest brace'
The efficacy of a new cervico-thoracic Neck-Chest brace (N-C brace) prepared for post- operative patients of cervical canal expansive laminoplasty was assessed. The orthosis is light in weight (300 g) and easy to fit. The effect of the orthosis to restrict the neck motion was studied in 10 normal young males by using lateral view radiographs in extension and flexion positions. The average range...
