Summary
This case report details a rare finger injury involving flexor digitorum profundus (FDP) avulsion and distal interphalangeal (DIP) joint dislocation. Prompt surgical repair led to successful functional recovery.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Distal interphalangeal (DIP) joint dislocations are uncommon, with irreducible dorsal dislocations being particularly rare.
- Potential causes include volar plate interposition, flexor digitorum profundus (FDP) tendon entrapment, or buttonholing of the middle phalanx head.
Observation:
- A 42-year-old male presented with trauma to his right middle finger from a workplace accident.
- Clinical examination and imaging revealed a combined FDP avulsion and dorsal DIP joint dislocation.
Findings:
- The patient underwent urgent surgical intervention.
- Successful reduction and repair of the FDP tendon were achieved, along with DIP joint stabilization.
Implications:
- This case underscores the necessity of timely diagnosis and surgical management for complex finger injuries.
- Effective treatment of FDP avulsion and DIP joint dislocation can restore satisfactory finger function.
