Associated conditionsEdit
Dactylitis can occur in seronegative arthropathies, such as psoriatic arthritis and ankylosing spondylitis, and in sickle-cell disease as result of a vasoocclusive crisis with bone infarcts, and in infectious conditions including tuberculosis, syphilis, and leprosy. In reactive arthritis, sausage fingers occur due to synovitis.<ref>Robbins, Stanley Leonard; Kumar, Vinay; Abbas, Abdul K.; Cotran, Ramzi S.; Fausto, Nelson (2010).

Template:ISBN.</ref> Dactylitis may also be seen with sarcoidosis.
In sickle-cell disease it typically occurs after 6 months of age (as in infants protective fetal hemoglobin, HbF, is replaced with adult hemoglobin and the disease manifests) and is often the first clinical presentation of the disorder.<ref>Template:Cite journal</ref>
