Evaluation of modified Kumar and Kalra myelopathy scoring system in sub-axial spinal pathologies

Background: Various pathologies affect the spine, but these lesions present with more or less similar clinical profile. The present functional scoring systems are inadequate and insensitive to changes in neurological status of the patient. Objective: Our study aims to assess the modified Kumar and Kalra (K and K) scoring system in patients with pathologies in the sub-axial spine. Materials and Methods: A total of 78 consecutive patients from the period of January 2009 to June 2010 were prospectively included in the study. These patients were operated by the senior author at our institute. The mean Modified Japanese Orthopaedic Association (MJOA) score and the mean modified K and K score were calculated in the preoperative, at the time of discharge (post-surgery), and at 3 months and 6 months follow-up. Results: There were 57 male (73.01%) patients and 21 female patients (26.92%), with the mean age of presentation of 39.20 years (±14.12 years) and a range of 9-75 years. Out of the total 78 patients, 60 patients had pathology in the cervical spine (sub-axial spine) and 18 patients had pathology in the dorsal spine. Majority of the patients had motor and sensory symptoms. The mean preoperative modified K and K score was 17.38 (±3.18) and the mean preoperative MJOA score was 11.21 (±2.12). The K and K score was able to predict the correct outcome in 70 patients (89.74%), whereas the MJOA score was able to predict correctly in 62 patients (79.49%). Conclusion: The modified K and K score has a better predictive value than the MJOA score.
