Usually the result of an underlying disease process

Presentation is indolent but progressive if therapy is not initiated

Similar findings to those found in infectious FT eventually present

Swelling is the most common initial finding

Hallmark is a difference in active, versus passive, flexion

As the tissue expands and impingement occurs, pain and restricted motion ensue

Delayed presentations can have the appearance of fulminant FT with all Kanavel signs or may involve tendon rupture if the patient delays seeking treatment long enough.

See Clinical Presentation for more detail.
