Proximal interphalangeal joint dislocations and fracture-dislocations.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Traumatology

Background:

• Proximal interphalangeal (PIP) joint dislocations are common hand injuries.
• PIP fracture-dislocations present a significant management challenge compared to simple dislocations.
• Fracture patterns vary widely, from simple avulsions to complex pilon fractures, complicating treatment and prediction of outcomes.

Purpose of the Study:

• To review the clinical presentations of PIP joint dislocations and fracture-dislocations.
• To categorize the diverse patterns of PIP fracture-dislocations.
• To discuss current treatment strategies and potential complications associated with these injuries.

Main Methods:

• Literature review of PIP joint injuries.
• Analysis of fracture patterns and classification systems.
• Discussion of surgical and non-surgical treatment modalities.

Main Results:

• PIP fracture-dislocations are significantly more complex than simple dislocations.
• Treatment difficulty correlates with fracture pattern complexity and stability.
• Subacute or chronic presentations further increase management challenges.

Conclusions:

• Effective management of PIP fracture-dislocations necessitates a thorough understanding of injury patterns.
• Treatment selection depends on fracture characteristics, stability, and chronicity.
• Anticipating and managing potential complications is crucial for favorable patient outcomes.
