Complex elbow instability involves dislocation with fractures of elbow stabilizers. Proper management is crucial to prevent chronic issues, though long-term surgical outcomes require further study.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomechanics

Background:

  • Complex elbow instability involves ulnohumeral joint dislocation with fractures of bony stabilizers like the radial head, coronoid process, or distal humerus.
  • Improperly managed complex elbow dislocations can lead to chronic, recurrent instability, posing a greater challenge than simple dislocations.

Purpose of the Study:

  • To review the current understanding and management strategies for complex elbow instability.
  • To highlight the need for further research into the long-term outcomes of surgical interventions for these injuries.

Main Methods:

  • Review of existing literature on complex elbow fracture-dislocations.
  • Analysis of prospective outcome studies evaluating specific fracture-dislocation patterns and treatment algorithms.

  • Assessment of surgical techniques including bony element fixation/replacement, ligamentous repair, and hinged fixation.
  • Main Results:

    • Complex elbow instability requires careful assessment and often surgical intervention for associated fractures (radial head, coronoid, olecranon).
    • Prospective studies are beginning to provide insights into the management of specific fracture-dislocation patterns.
    • Various surgical methods, including fixation, repair, and hinged fixation, show potential for successful management.

    Conclusions:

    • Complex elbow instability is a demanding condition requiring comprehensive management of both dislocation and associated fractures.
    • While surgical techniques exist, the long-term outcomes of managing complex elbow injuries remain an area needing further investigation.
