Summary
This study details closed injuries to the finger extensor apparatus, including mallet finger and Boutonnière deformity. Treatment options range from splinting and temporary arthrodesis to surgical fixation for severe cases.
Area of Science:
- Hand surgery
- Orthopedic trauma
- Reconstructive surgery
Context:
- The extensor apparatus of the fingers is a complex anatomical structure crucial for hand function.
- Closed injuries, such as mallet finger and Boutonnière deformity, significantly impair finger extension.
- Understanding the intricate structure is key to diagnosing and managing these injuries.
Purpose:
- To describe the anatomy and common closed lesions of the finger extensor apparatus.
- To outline current conservative and operative treatment strategies for mallet finger and Boutonnière deformity.
- To provide insights into the management of avulsion fractures and tendon injuries.
Summary:
- Mallet finger involves avulsion of the extensor tendon insertion or fracture of the distal phalanx base, often treated non-operatively with splinting or Kirschner-wire fixation.
- Larger bony fragments require operative fixation, potentially augmented by temporary arthrodesis for 7 weeks, followed by nocturnal splinting.
- Boutonnière deformity results from central extensor tendon injury, managed conservatively with splinting or surgically with tendon repair in early presentations.
Impact:
- Provides a comprehensive overview of finger extensor apparatus injuries and their management.
- Highlights the importance of accurate diagnosis for effective treatment selection.
- Offers guidance for orthopedic and hand surgeons managing these common hand injuries.
