Despite good posterior decompression of thoracic myelopathy due to ossification of ligamentum flavum (OLF), recovery varies widely from 25 to 100%. Neurological status on presentation also varies widely in different patients. We, therefore retrospectively studied relation of various clinical and magnetic resonance imaging (MRI) parameters with preoperative neurological status and postoperative recovery in 25 patients who underwent decompressive laminectomy for thoracic myelopathy due to OLF. Patients were assessed using leg-trunk-bladder scores of JOA scale and recovery rate (RR) was calculated as RR = postoperative score -preoperative score/11 -preoperative score 9 100. With Pearson's correlation, postoperative recovery rate (RR) significantly correlated with preoperative duration of symptoms, JOA score, sensory JOA score, canal grade, dural canal-body ratio (DCBR), intramedullary signal size (ISS), and intramedullary signal type (IST) on MRI. On MRI, two types of signal changes were identified: normal in T1/hyperintense in T2 representing cord edema and hypointense in

Bradycardia and rarely cardiac arrest as a complication of cervical spine injury due to reduced sympathetic activity is well known, which usually settles down in 4-6 weeks of injury. There are few case reports in literature of high cervical spinal cord injury requiring permanent cardiac pacemaker due to this complication, but an injury as low as cervico-dorsal junction requiring permanent cardiac pacemaker has never been reported. A 47-year-old male suffered traumatic C7-D1 dislocation and continued to have severe bradycardia with multiple episodes of cardiac arrest till 2 months after injury, which finally warranted permanent cardiac pacemaker as a life saving measure. Following permanent cardiac pacemaker no cardiac arrest occurred and the patient was successfully rehabilitated. The case directs our attention to a rare complication of cardiac arrest occurring in an injury as low as cervico-dorsal junction when all other causes are ruled out and shows importance of using permanent cardiac pacemaker to ensure patient safety in community.
