Summary

Central slip attachment fractures, often linked to PIP joint injuries, require prompt recognition. Open reduction and internal fixation can prevent boutonniere deformity and enable early joint mobilization.

Area of Science:

  • Orthopedic surgery
  • Hand surgery
  • Traumatology

Background:

  • Central slip avulsion fractures are a specific type of proximal interphalangeal (PIP) joint injury.
  • These injuries disrupt the extensor mechanism, potentially leading to boutonniere deformity.
  • Accurate diagnosis and treatment are crucial for restoring joint function.

Purpose of the Study:

  • To present a classification system for central slip attachment fractures based on injury mechanism.
  • To describe the outcomes of treating displaced central slip avulsion fractures with open reduction and internal fixation (ORIF).
  • To emphasize the importance of recognizing these fractures as part of a dynamic extensor mechanism disruption.

Main Methods:

  • Retrospective review of eight patients with displaced central slip attachment fractures.

  • Treatment involved open reduction and internal fixation (ORIF).
  • Fractures were classified into three types based on the mechanism of injury.

    • Main Results:

    • Open reduction and internal fixation (ORIF) allowed for anatomical reduction of the fractures.
    • Early joint mobilization was facilitated by the surgical intervention.
    • The treatment aimed to prevent the development of boutonniere deformity.

    Conclusions:

    • Central slip attachment fractures are intra-articular injuries that compromise the extensor mechanism.
    • A classification system based on injury mechanism aids in guiding treatment.
    • ORIF is an effective method for treating displaced fractures, enabling early motion and preventing deformity.
