Suture fixation versus tension band wiring in simple displaced olecranon fractures – a study protocol

INTRODUCTION: Olecranon fractures, particularly the Mayo Type 2A two-part fracture, are typically treated with Kirschner wires (K-wires) and tension band wiring. While effective, this method is associated with a high complication risk, leading to reoperations. Recently, new suture fixation techniques have been described that do not involve the insertion of metal. This new technique may mitigate risks associated with K-wires and tension band wiring without impacting healing or function. This study compares the reoperation rate and outcome of suture fixation with traditional tension band wiring. METHODS: This is a prospective, randomised, double-blinded, multicentre study. The allocation ratio is 1:1, and the groups are parallel. A total of 88 adult participants will be recruited. Participants will be assigned to receive either suture fixation or traditional tension band wiring. Follow-up is one year. The primary outcome is the reoperation rate. Secondary outcome measures include the Disabilities of the Arm, Shoulder and Hand (DASH), the EuroQol-5 Dimensions (EQ-5D) score, radiological outcomes and complications. CONCLUSIONS: There is room for improvement in treating Mayo Type 2A fractures, and this study will allow us to investigate a new treatment method. The new suture fixation technique for treating olecranon fractures can potentially offer a similar or improved functional outcome compared to tension band wiring while lowering the reoperation rate significantly. FUNDING: The study is initiated and conducted by the participating physicians within the financial framework of the participating departments. TRIAL REGISTRATION: The trial is registered with www. CLINICALTRIALS: gov, ID number: NCT04189185.
