Conjoint Lumbosacral Nerve Root-A Case Report

INTRODUCTION: Conjoint nerve root is embryological nerve root anomaly mainly involving lumbosacral region. The anomalous roots present primarily as a bifid, conjoined structure arising from a wide area of the dura. Because of their size and attachment to surrounding structures, they are uniquely susceptible to trauma. The effects of compression and entrapment are amplified in the presence of stenosis of the lateral recesses where developmental changes and disc herniations deplete the available reserve space [1]. CASE REPORT: We report a case of conjoint lumbosacral nerve root which was missed on MRI and diagnosed intra-operatively. CONCLUSION: The importance of the case report lies in the fact that one must be aware of finding conjoint nerve root directly while operating and do appropriate level of surgery, misinterpretation can lead to devastating results.
