Summary

Vertically unstable pelvic ring injuries can cause irreducible sacroiliac (SI) joint dislocations. This case highlights the limitations of closed reduction, necessitating open surgery for locked ilium dislocations.

Area of Science:

Orthopedic surgery
Trauma management
Pelvic anatomy

Background:

Vertically unstable pelvic ring injuries frequently involve sacroiliac (SI) joint disruption.
Understanding pelvic biomechanics is crucial for managing these complex fractures.

Observation:

A case of irreducible SI joint dislocation is presented, characterized by superiorly locked ilium.
Initial closed reduction attempts were unsuccessful in repositioning the dislocated joint.

Findings:

The irreducible nature of this specific SI joint dislocation required surgical intervention.
Open reduction was ultimately necessary to restore pelvic alignment.

Implications:

This case underscores the limitations of non-operative management for certain severe pelvic injuries.
Expert anatomical knowledge and procedural skill are essential for successful SI joint reduction, both closed and open.
