Background: Skeletal manifestations are predominant in psoriatic arthritis (PsA). The aim of this cross-sectional, case-controlled study is the complex assessment of areal and volumetric bone mineral density (BMD), fracture risk, vitamin D status and bone turnover markers, and its association with disease-related variables.Methods: Lumbar spine (L1-L4) and femur neck (FN) areal, and distal radius (DR) volumetric BMD, 10-year probability of major and hip osteoporotic fracture as assessed by the fracture risk assessment (FRAX) tool, markers of bone metabolism and disease activity were assessed.Results: Upon comparison of the disease and age- and sex-matched control groups, there was a statistically significant difference in FN areal (0.955±0.145 g/cm2 vs. 1.034±0.148 g/cm2; p=0.001) and DR total volumetric (285.7±61.8 mg/cm3 vs. 369.6±23.6 mg/cm3; p
