Abstract |
Objective |
To describe echographic abnormalities on the proximal (PIP) and distal (DIP) interphalangeal joints of healthy subjects.
Methods |
Healthy asymptomatic volunteers under forty were enrolled. Ultrasonography was performed on PIP and DIP 2–5 in the presence of two operators. In B mode, synovial hypertophy and effusion were defined with the OMERACT criteria. In power Doppler mode, the inflammatory activity was evaluated.
Results |
46 subjects were enrolled: mean age 25.5 years, 89% right handed. 368 PIPs and DIPs were scanned. Effusion was found in 19.6% of dominant PIPs versus 22.3% of non-dominant PIPs (p>0.05). Effusion could be uni- or bilateral. DIP effusion was less frequent (3% DIPs). Average size of effusion was 0.83±0.25mm for PIP and 0.72±0.16mm for DIP.
Conclusion |
Our study proposes a descriptive analysis of the PIP and the DIP joints. It confirms, with a bigger number of studied joints, the possible existence of a physiological effusion of the PIP of healthy subjects. It is the first descriptive study of the normal DIP where the presence of an effusion is very rare.
