Introduction: The functionality of the lumbar spine is anatomically influenced by the sizes of the lumbar vertebra.

Aim: The present study was done to analyze the morphometry of dry lumbar vertebrae of a south-southern Nigerian population. Materials and methods: Using a cross-sectional, observational study design, fifty (50) dry lumbar vertebrae (40 typical and 10 atypical) of unknown age and sex were obtained from selected anatomical museums and metric pedicle parameters such as height (PH) and width of pedicle (PW), and interpedicular distance (IPD) were measured with a digital vernier caliper to the nearest 0.01 mm and later analyzed using SPSS version 23.

Results: There was a progressive decrease in mean PW from L1 to L5 while both mean values of PW and IPD depicted continuous rises from L1 to L5 was observed. Apart from PH, the mean differences for PW and IPD for all lumbar vertebrae were statistically significant (p = 0.00).

Conclusion: The study values will be relevant for the purpose of clinical diagnosis as well as to aid in forensic investigations.
