TBW vs Plating in Olecranon Fractures

Study Overview
=================
Brief Summary
-----------------
Background: While the tension band wiring (TBW) technique is commonly used for simple, displaced olecranon fractures, it is associated with complications such as hardware prominence. To date, studies comparing between the efficacy and safety of TBW and plate fixation for these fractures have not provided a conclusive answer. Purposes: To investigate which of the two techniques provide better functional and radiological outcomes for simple displaced Mayo type 2A olecranon fractures, Which technique provides better patient-reported outcomes, What are the complication rates associated with each technique

Background: While the tension band wiring (TBW) technique is commonly used for simple, displaced olecranon fractures, it is associated with complications such as hardware prominence. To date, studies comparing between the efficacy and safety of TBW and plate fixation for these fractures have not provided a conclusive answer. Purposes: To investigate which of the two techniques provide better functional and radiological outcomes for simple displaced Mayo type 2A olecranon fractures, Which technique provides better patient-reported outcomes, What are the complication rates associated with each technique Methods: A long-term, prospective, randomized study on 50 adult patients who underwent surgery to treat acute, simple, displaced olecranon fractures in a Hand and Upper Extremity Surgery Unit at a tertiary care center between November 2012 and October 2017. Patients were randomized on a 1:1 basis to either tension band or plate fixation and were evaluated at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year after surgery. Evaluation of long-term complications continued after 1 year as clinically indicated. The primary outcome measure was the 1-year postoperative Disabilities of the Arm, Shoulder and Hand (DASH) score. Additional outcome measures included patient-reported Oxford elbow score, functional (i.e., range of motion) and radiographic assessments and complication rates.
