Psoriatic arthritis is associated with bone loss of the metacarpals

Background BoneXpert (BX) is a newly developed medical device based on digital X-ray radiogrammetry to measure human cortical bone thickness. The aim of this study was to quantify cortical bone loss of the metacarpals in patients with psoriatic arthritis (PsA) and compare these findings with other radiological scoring methods. Methods The study includes 104 patients with verified PsA. The BX method was used to measure the Metacarpal Index (MCI) at the metacarpal bones (II-IV). Additionally, the T-score of the MCI (T-scoreMCI) was calculated. Radiographic severity was determined by the Psoriati... Mehr ...
