Trans-olecranon fracture dislocations: How should we treat them? *

Background: Trans-olecranon fracture dislocations are the least frequent complex elbow instability. Proper surgical treatment should be performed to avoid postoperative complications. Methods: A retrospective design study was performed. Patients that suffered from this injury, treated at our center from 2010 to 2016 were included. Fifteen patients were analyzed. Functional results were measured using DASH, MEPS and VAS scores. Average time from injury to first surgical treatment was 4.87 days. Radial head fracture was present in seven cases and coronoid process in three patients. Most frequent complication was hardware disturbances in five patients. Mean follow up was 3.65 years. Results: Mean range of motion (ROM) was evaluated 1 year postoperatively: 129 degrees flexion, 6 degrees flexion contracture, and less than 5 degrees deficit of pronation/supination. Clinical and functional results are encouraging, DASH 36.38, MEPS 100 and VAS 0.46. Conclusion: Trans-olecranon fracture dislocations could obtain functional range of movement, pain relief and good functional outcomes with a standardized protocol of surgical fixation. It is important to achieve proper ulnar fixation, focusing in reestablishing dorsal angulation, and also to treat radial head and coronoid injuries properly, if present. (c) 2021 Elsevier Ltd.

Automated summary

Proper surgical treatment of trans-olecranon fracture dislocations should focus on addressing any associated radial head and coronoid injuries, achieving proper ulnar fixation with dorsal angulation restoration. Clinical and functional outcomes suggest good results and functional recovery in patients post-surgery.
