Study Notes
Jersey Finger Overview
- Jersey finger is a traumatic injury affecting the flexor tendon, resulting from an avulsion of the flexor digitorum profundus (FDP) tendon at its attachment point on the distal phalanx.
Treatment Options
- Treatment typically involves several approaches including:
- Direct tendon repair for optimal healing.
- Open reduction and internal fixation (ORIF) for associated fracture fragments.
- Two-stage flexor tendon grafting for more extensive injuries.
- Distal interphalangeal (DIP) arthrodesis when necessary.
Clinical Signs
- Key indicators of jersey finger include:
- Pain and tenderness localized over the volar aspect of the distal finger.
- During rest, the affected finger often remains in slight extension compared to adjacent fingers.
- Inability to flex the DIP joint, with a possibility of palpating the retracted flexor tendon along the flexor sheath.
Possible Complications
- Quadrigia phenomenon may occur, characterized by the inability to flex an adjacent finger when the FDP of one finger has been injured.
Classification System
- The classification of jersey finger injury includes:
- Type I: FDP tendon retracts to the palm, disrupting blood supply.
- Type II: Tendon retraction extends to the proximal interphalangeal (PIP) joint.
- Type III: Involves a large avulsion fracture of the bone at the DIP joint.
- Type IV: Combination of osseous fragment with FDP retraction to the palm.
- Type V: FDP avulsion still attached to the osseous structure but is stuck on the distal phalanx.
