Abstract · Introduction · Methods · Results
The line joining the superior aspect of the iliac crests posteriorly (the intercristal line) is commonly stated to cross the midline at the L4 or L4–5 spinal level on imaging. This study aimed to assess the spinal level identified through palpation ...

It is widely believed that the spinal level of the iliac crests corresponds to the L4 spinous process (SP) or the L4–5 interspinous space. A previous meta- ...
This is a secondary analysis of two previous systematic reviews demonstrating cephalad bias in using palpation to enumerate lumbopelvic levels, based on the conventional landmark rule that the spinal level of the palpated iliac crests=L4. Our study included ...

Objective: To compare the clinical usefulness of the posterior superior iliac spine (PSIS) with that of iliac crest (IC) for identifying the lumbar vertebral level Method: Lumbar spine level was identified by the line connecting bilateral upper margin of iliac crests in the antero-posterior lumbar X-rays of 120 patients. Assumed IC level and assumed PSIS level were compared by 3 examiners' palpation in 60 patients. A marker was taped on assumed IC level and assumed PSIS level by 4 examiners and the postero-anterior lumbar X-rays was taken in randomly distributed 50 patients Results: IC intersection line was ranged from the L4 spinous process to the L5-S1 interspinous process in all patients. Inter-examiner agreement of palpation was significantly greater in PSIS than IC level (P<0.05). The marker indicating assumed IC level was higher than true IC level in all patients and was higher than L3-4 interspinous process in 8% Conclusion: We may use PSIS level for assumption of the lumbar vertebral level to compensate for the limitation of iliac crest palpation, but at the same time keep in the mind the variarity of the PSIS level.
