Purpose: The purpose of this study is to evaluate the surgical outcomes of olecranon fracture dislocation in accordance with the direction of the dislocation.
Materials and Methods: From December 2006 to February 2016, the surgical outcome in patients who had been followed-up for a minimum of 6 months accompanied with olecranon fracture and elbow instability were reviewed retrospectively. We classified olecranon fracture as either the anterior type or the posterior type. Moreover, we evaluated the clinical results by the Mayo elbow performance scores (MEPS) and checked for any associated injury, age, injury mechanism, and complication.
Results: Fourteen patients had anterior transolecranon fracture dislocation, with an average age of 46 years. The associated lesions were radial head fractures found in 2 patients (14.3%) and coronoid process fracture found in 5 patients (35.7%). Patients with anterior transolecranon fracture showed an average MEPS of 93.2 (70?100). Eight patients with posterior olecranon fracture dislocation had an average age of 66 years (22?87 years). The associated lesions were radial head fractures in 6 patients (75.0%) and coronoid process fracture in 8 patients (100%). Patients with posterior olecranon fracture dislocation showed an average MEPS of 94.4 (80?100). In comparison with the anterior type, posterior type occurred more frequently in elders and showed a greater association with injuries, such as radial head fracture and coronoid process fracture. However, there was no significant difference between the two groups with respect to the clinical outcome.
Conclusion: There were differences in frequency of associated injuries and age in accordance with the direction of olecranon fracture dislocation. Moreover, good clinical outcomes were achieved by surgical treatment.
