Acromioclavicular Joint Pseudo-dislocations with Lateral end Clavicle Fracture: A Rare Injury and Proposed Technique of Fixation.

Introduction: Lateral end clavicle fractures are rare injuries in pediatric and adolescent population. Most of these injuries can be managed conservatively. However, in patients with acromioclavicular joint (ACJ) "pseudo-dislocations" associated with significant clinical deformity, some patients will benefit from operative intervention.

Case Report: Our reported case is a young adolescent with a Type IV Dameron and Rockwood distal clavicle fracture and ACJ pseudo-dislocation, who underwent surgical fixation for this injury. We propose a novel technique of fixation with a suture anchor and endo button with temporary K wire stabilization. These are rare injuries and there are no standardized techniques for reconstruction and fixation. Stabilization with a suture anchor can provide a minimally invasive method of fixation for such injuries without the traditional plating and can lead to excellent final outcomes.

Conclusion: ACJ pseudo-dislocations are rare injuries. There is limited evidence in guiding the management of such injuries. Our proposed technique of fixation with suture anchor, endo button and temporary stabilisation with K-wire can provide promising results.
