Background:
Hand osteoarthritis (OA) can be a distressing disorder that impairs a patients' quality of life. There is a relation between OA and vascular damage, especially atherosclerosis, and OA are both common chronic conditions associated with aging and obesity.
Aim of the study:
The objective of this research was to examine nailfold microcirculation in individuals with hand OA
Patients and Methods:
a cross-sectional, observational study, about 56 patients with hand OA were enrolled. All subjects underwent a standard radiology X-Ray examination of the hands and a Nailfold vascular examination was performed.
Results: of the 56 patients studied were females, and 12 were males. Regarding the Kellgren and Lawrence scoring, it was mild (grade II) in one patient (50%) and severe (grade IV) in one patient (50%) in the male patients without pain, while in those with hand pain, it was moderate (grade III) in eight patients (80%) and severe (grade IV) in two patients (20%).it was mild (grade II) in eight patients (22.2%), moderate (grade III) in 21 patients (58.3%) and severe (grade IV) in seven patients (19.4%). Nailfold examination for studied subjects showed that there were about 41 patients (73.2%) with low capillary density and 32 patients (57.1%) with morphological changes.

Conclusion:
Our findings provided a general description of the NFC findings most likely to be seen in OA patients; Vascular anomalies may play a role in the illness progression and may assist in elucidating because the condition is frequently found in the distal digit joints.
