Musculoskeletal ultrasonography is gaining favor in the evaluation of enthesitis in patients with psoriasis and psoriatic arthritis (PsA). Imaging modalities have shown that the enthesis of the distal interphalangeal joint has a close relationship to the nail itself. Studies have focused on the structure and morphology of nails to determine an association between psoriasis nail changes and the presence or severity of PsA. With the use of higher frequency probes, power Doppler (PD) can determine subclinical inflammation of the area under ultrasound examination. At the 2016 meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), we proposed an ultrasonographic index for the assessment of the nail enthesis to identify the morphologic and PD findings of the nail, with the potential that both rheumatologists and dermatologists can use it to evaluate their patients.
肌肉骨骼超声检查在评估银屑病和银屑病关节炎（PsA）患者的附着点炎方面越来越受到青睐。影像学检查表明，远端指间关节的附着点与指甲本身关系密切。研究聚焦于指甲的结构和形态，以确定银屑病指甲改变与PsA的存在或严重程度之间的关联。通过使用更高频率的探头，能量多普勒（PD）可确定超声检查区域的亚临床炎症。在2016年银屑病和银屑病关节炎研究与评估小组（GRAPPA）会议上，我们提出了一种用于评估指甲附着点的超声检查指标，以识别指甲的形态学和PD表现，有望让风湿科医生和皮肤科医生都能使用它来评估患者。
