Erratum to: Anat Sci Int DOI 10.1007/s12565-016-0343-0

The author would like to correct the errors in the original publication of the article. The corrected details are given below for your reading.

In the abstract section, the word ‘‘delete’’ should be removed in the sentence ‘‘The linear distances between the CMT, DST and SHA… membrane were also measured’’. The P value should be “(P > 0.05)”, in the sentence “In the MRI study, the mean vertebral …”.

The last sentence in the first paragraph beneath the heading “Material and methods” on page 2 should be “The male and female patients who underwent these MRI studies and who satisfied the inclusion criteria were enrolled in the study and classified into six age groups as follows: < 20 years (10 patients); 20–29 years (20 patients); 30–39 years (20 patients); 40–49 years (20 patients); 50–59 years (20 patients); ≥ 60 years (10 patients)”.

Also, Fig. 2 is a duplicate of Fig. 3. The correct Fig. 2 is placed in the following page.
