Table 2 Bone mineral density (BMD), T score and Z scores, prior to and after parathyroidectomy

From: Case report: lady with bone pains for 5 years—parathyroid carcinoma

Scan date 02/12/2009 (pre operative) 11/01/2011 (post operative)
BMD hip (g/cm2)◦ 0.498 0.886
T score hip − 3.6 − 0.5
Z score hip − 3.1 0.2
BMD spine (g/cm2)◦ 0.729 0.933
T score spine − 2.9 − 1.0
Z score spine − 2.0 − 0.0
BMD forearm (g/cm2)◦ 0.333 0.402
T score forearm − 4.5 − 3.2
Z score forearm − 3.6 − 2.2
  1. ◦BMD values at our institute (AKUH) for DXA done on 2.12.2009 were compared with the study of 11.01.2011. The comparative analysis showed statistically significant improvement in BMD values. The change in BMD was greater than the Least Significant Change (LSC) of our Department at AKUH for each region of interest. Therefore, it was considered significant (LSC for AKUH is: Hip: 0.030; Spine: − 0.034; Forearm: 0.043)
  2. As per Institute protocol and World Health Organization (WHO) guidelines BMD of only the non-dominant hip (in this patient’s case, the right hip) was measured, (position statement of International Society for Clinical Densitometry, attached as Additional file 1)
