Pull Out Suture Technique for Fixing Coronoid Fractures using a Single Lateral Extensor Digitorum Communis Split...

Area of Science:

• Orthopedic Surgery
• Trauma Management
• Elbow Biomechanics

Background:

• Coronoid process (CP) fractures challenge elbow stability and function.
• Surgical intervention is often necessary for displaced or comminuted CP fractures.
• Traditional fixation methods can be complex and bone-intensive.

Purpose of the Study:

• To present a novel surgical technique for coronoid fracture fixation using FiberWire and Endobutton.
• To evaluate the efficacy and outcomes of this technique in patients with coronoid fractures.
• To assess the potential of this method for improving elbow stability and facilitating early mobilization.

Main Methods:

• A novel technique involving FiberWire and Endobutton fixation was applied to six patients with coronoid fractures.
• The approach utilized a single lateral split of the extensor digitorum communis.
• Patients were followed for 1 year, with functional outcomes assessed using the Mayo Elbow Performance Index and Disabilities of the Arm, Shoulder, and Hand score.

Main Results:

• The technique provided reliable fixation for Type 1 and Type 2 coronoid fractures.
• Patients experienced early mobilization and stable elbow joints with a satisfactory functional arc.
• The method demonstrated positive results, including a prompt return to activity, especially for comminuted fractures.

Conclusions:

• Coronoid fracture fixation with FiberWire and Endobutton offers reliable and strong fixation.
• This technique minimizes soft tissue disruption and allows for early patient mobilization.
• It represents a promising surgical management option for Type 1 and Type 2 coronoid fractures.
