Ultrasonographic findings in metatarsophalangeal and talocrural joints in healthy persons.
The objective of this study was to establish whether healthy persons have effusions detectable by ultrasonography (US) in metatarsophalangeal (MTP) and talocrural (TC) joints. Fifty consecutive healthy persons without symptoms in ankles and feet were studied. Thirty-eight of them were women, and their mean age was 47.4 (range 23-62) years. Eighteen of the 500 MTP joints studied in nine persons and four of the 100 TC joints in three persons showed effusions upon investigation. One person had effusion in five MTP joints, one in four, two in two, and the remaining five in one MTP joint. None of the studied joints yielded pathological findings in Doppler US examination. These results indicate that the detection of effusion by grayscale US in the absence of Doppler US in MTP and TC joints can be found in healthy persons.
