| Summary: | Background: Aim of this study was to establish acceptable cut off values of psoas muscle
area (PMA) for evaluation of low muscle mass in postmenopausal osteoporotic women.
Methods and Materials: Ninety-five women with postmenopausal osteoporosis who had
underwent lumbar spine MRI and dual energy x ray absorptiometry were retrieved
retrospectively. Psoas muscle cross-sectional area (CSA) and index were measured at L3-
level and cut off values of PMA were investigated for age groups. Results: Of the ninety-five
women with postmenopausal osteoporosis (63.96 ± 9.19 years), the rate of sarcopenia was
16.7% (n= 10) in the ≤ 65 age group, 22.2% (n= 10) in the > 65 age group and 19% (n= 20) in
total. The cut off values of PMA were determined as 468.55 mm2 and 479.20 mm2 for ≤ 65
and > 65 years of age groups, respectively. The evaluation of intra-observer reliability
resulted almost perfect with intraclass correlation coefficient ranging from 0.997 to 0.999
(p<0.001). The inter-observer reliability was also almost perfect with intraclass correlation
coefficients ranging from 0.994 to 0.999(p<0.001). Conclusions: This study has provided cut
off values for MRI defined PMA in postmenopausal osteoporotic women. Further
longitudinal studies are required to confirm whether these cut offs are successful in
predicting mortality and other adverse outcomes. |
