Brief summary

The aim of this study is to investigate the sonographic differences in entheses in patients with Rheumatoid arthritis and Axial Spondyloarthropathy.

Detailed description

After recording the demographic data of the patients; 5 enthesis regions 5 enthesis sites were evaluated bilaterally as ''tricipital tendon (TT), quadricipital tendon (QT), proximal patellar tendon (PPT), distal patellar tendon (DPT), achilles tendon (AT)'' will be sonographically evaluated and the presence of hypoechogenicity , tendon thickness increase, power Doppler activity, erosion, presence of entezophyte/calcification will be investigated. The differences between the groups will then be compared.

Interventions

OTHERULTRASOUND

10 enthesis areas will be evaluated in 20 minutes with ultrasound.
