Introduction: The subarachnoid block is performed in sitting or lateral position with the flexion of patients back. Flexed back for spinal anaesthesia is considered facilitatory as it helps in widening the interspinous space. Aims & objectives: The aim of our study was to find out the degree of procedural success and patient preference when subarachnoid block was performed in suboptimal flexion of the back. Methods: 120parturients between 22-40 yrs of ASA grade 1& 2 undergoing LSCS were randomized into 4 groups of 30 each. Observations and results: Overall success rates of subarachnoid needle placement were 100% in all the groups. No patient in any of the groups required needle redirection because of lack or inadequate flow of CSF. All redirections were because of repeated bony contacts. Redirections required at 1st attempt were noted in 9, 13, 21 and 11 patients among the LS, LF, SS & SF groups respectively. The rest of patients needed them at 2nd attempt. Conclusion: Lumbar puncture can be performed with equal ease in sitting patient regardless of the posture of back being in a flexed or a straight posture provided that the landmarks are clear
