Jersey Finger: Diagnostic Approach and Treatment Principles

Diagnostic Approach

• Radiographs are always indicated as initial imaging to detect avulsion fractures or bony fragments in patients with suspected jersey finger, according to the American College of Radiology 3
• Standard radiographs may be normal in purely tendinous avulsions, but MRI is ideal for evaluating tendon injuries and surgical planning, including assessment of the level of tendon retraction, quality of the tendon stump, and associated pulley injuries in athletes with jersey finger, as recommended by the American College of Radiology 1, 2

Treatment Principles

• Early presentation (within 10 days) is associated with superior functional outcomes in patients with jersey finger, and surgical treatment is required, as stated by the American College of Radiology 1, 2
