Locking Compression Plates in Proximal Ulna Fractures: A Study on Functional Outcomes

Background : Proximal ulna fractures, such as olecranon and Monteggia fractures, can be challenging to treat. Objective : To assess the effectiveness of locking compression plates (LCP) in stabilizing and promoting early mobilization in these fractures. Materials and methods : This is a prospective study conducted at Saveetha Medical College and Hospital from January 2022 to December 2023. Patients with compound fractures, pediatric fractures, proximal bilateral forearm fractures, and those considered medically incompetent for surgery were excluded from the study. Results : Of 20 patients with olecranon and Monteggia fractures, the majority had comminuted olecranon fractures. Most cases did not have associated injuries, while a few had radial head or coronoid injuries. Fracture union times varied, with some cases taking 12, 16, or 18 weeks to heal. Most patients achieved good elbow range of motion, exceeding 100° in 75% of cases. One patient experienced an exposed implant, one developed an infection, and 3 cases had restricted terminal pronation and supination. Functional outcomes assessed using the Mayo Elbow Performance score were excellent in 16 patients and good in 4 patients. Conclusions : That comminuted olecranon and proximal ulna fractures can be effectively treated with LCP, resulting in good union and excellent clinical outcomes.
