All-Suture Anchor Fixation for Coronoid Process Fractures via a Transolecranon Fracture Approach

Coronoid process fractures are a common component of elbow injuries and present significant challenges in surgical management. The all-suture anchor fixation technique, as an emerging method, offers a novel alternative for stabilizing these fractures. By enabling dual-directional fixation, this approach provides bidirectional mechanical support, resulting in enhanced stabilization of the fracture fragment.

A 35-year-old male presented with a complex proximal ulnar fracture involving both the coronoid process (O'Driscoll Type III) and the olecranon. Surgical fixation was performed using an all-suture anchor inserted at the fracture site, with sutures strategically tied to a fixation plate, establishing a stable tension-band configuration. This construct provided controlled traction and stable three-dimensional support of the fragment. Postoperative recovery was uneventful, with full restoration of elbow function and no evidence of fragment displacement or complications.

This case illustrates the technical feasibility of the all-suture anchor technique for coronoid fractures. In cases of complex proximal ulnar fractures, this technique allows for simultaneous fixation of the coronoid and olecranon through a single posterior approach, reducing soft tissue disruption.
