Perilunar dislocations of the wrist, often from high-speed accidents, cause carpal instability. Surgical intervention, including ligament repair and fracture stabilization, is necessary for effective treatment.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Radiology

Background:

  • Perilunar dislocations typically result from high-energy trauma, such as falls onto an outstretched hand.
  • These injuries involve disruption of the wrist's articular structures, leading to carpal instability.
  • Instability presents with symptoms like pain, limited motion, carpal instability, snapping, and swelling.

Purpose of the Study:

  • To summarize the causes, clinical presentation, diagnostic methods, and treatment of perilunar wrist dislocations.
  • To emphasize the importance of operative management for perilunar instability and associated injuries.

Main Methods:

  • Diagnosis is established using imaging modalities including X-ray, cinematography, arthrography, Magnetic Resonance Imaging (MRT), and Computed Tomography (CT).

  • Evaluation of ligamentous and bony integrity is crucial for staging instability.

    • Main Results:

    • Perilunar dislocations are associated with significant carpal instability due to damage to various joint structures.
    • Associated fractures and conditions like de Quervain's tenosynovitis can occur concurrently.
    • Clinical presentation includes pain, restricted movement, carpal instability, and swelling.

    Conclusions:

    • Perilunar wrist dislocations require prompt diagnosis and operative treatment.
    • Surgical management should address ligamentous repair and fracture stabilization for optimal outcomes.
    • Early intervention is key to managing the instability associated with these complex wrist injuries.
