Ganglion involving the tendon sheath
Infection within the tendon sheaths
Ganglion cyst of the wrist

Workup
Laboratory Studies
- As a rule, no lab tests are needed in the diagnosis of trigger finger. If there is a concern regarding an associated, undiagnosed condition, such as diabetes, rheumatoid arthritis, or another connective tissue disease, an assessment of, respectively, glycosylated hemoglobin (HgbA1c), fasting blood sugar, or rheumatoid factor should be ordered.
Imaging Studies
- Generally, no imaging studies are needed in cases of trigger finger.
Other Tests
- No further tests are usually required.
Procedures
- Injection of the trigger digit is generally considered to be therapeutic rather than diagnostic. (See Other Treatment.)
