Developments in treatments of ulnar coronoid process fracture

Hongwei Chen, Guolin Wu

Ulnar coronoid process (UCP) fracture is a complex intra-articular fracture, but not common in clinical practice. During surgeries, it is difficult to expose the coronoid process due to complicated surrounding anatomical structures. Moreover, UCP fracture also has a variety of clinical complications. Thus, its treatments have been a challenge and a focus in clinical studies. At present, it is widely accepted that early surgical treatment is required for UCP fracture. Different surgical approaches and fixation techniques have been proposed. However, the optimal approach/technique still remains unclear. In this study, the classification of UCP fractures, surgical approaches, internal fixation techniques, and other relevant issues were reviewed aiming to improve therapeutic efficacy of UCP fracture and reduce its complications.
