Intensitas Mielum pada Gambatan MRI Servikal sebagai Faktor Prognostik Luaran Cervical Spondylosis Myelopathy Pascaoperasi

Introduction: Cervical spondylosis myelopathy (CSM) is a stenosis condition in cervical canal due to the cervical structural changes that compress the myelum, thus causing spinal medulla ischemia. Other than clinical factors, myelum intensity changes on MRI T1-weighted images (T1W1) and T2W1 might be useful to predict the pos-operative outcome.

Aims: Identify prognostic factors in post-operative patients with CSM based on clinical symptoms and myelum intensity on cervical MRI.

Methods: Retrospective study on CSM patients who underwent surgery in Neurosurgery Department, Cipto Mangunkusumo hospital, Jakarta, from January 2013 to December 2016. Magnetic resonance imaging data was obtained before the surgery, while clinical symptoms were assessed by Nurick scale before and 1 year after the surgery to evaluate outcome.

Results: There were 50 subjects included in this study with mean age 51.98±9.64 years, majority male (76%), have moderate myelopathy (Nurick scale pre-operative ≤2), and time between onset and surgery mostly ≤1 year (80%). Most subject (88%) had improvement clinically, but mostly without hypointensity on cervical T1W1 MRI.
