- Avulsion of flexor tendon from distal phalanx
- Occurs from forced extension of flexed DIP (historically from grabbing someone's jersey with the tip of a finger)
- Inability to actively flex DIP joint
- Full passive ROM is maintained
- Distal finger
- Other finger/thumb
- Finger splint in slight flexion at DIP
- Early follow-up (24-48 hours) with hand specialist - surgery is required for all Jersey finger injuries
- Based on Leddy and Packer Classification
|I||Vincula ruptured with tendon retraction to palm||Primary tendon repair within 10 days|
|II||Vincula intact with tendon retraction to proximal interphalangeal joint||Primary tendon repair within 10 days (but may be delayed)|
|III||Fracture fragment retains tendon at distal interphalangeal joint||Repair of fracture fragment (6 weeks)|
|IV||Fracture fragment has tendon avulsed off and retracted||Repair of fracture fragment and tendon repair (12 weeks)|
