Case SeriesA figure-eight suture loop with Kirschner wires for fixation of anteromedial coronoid process fractures: A case series

- Eleven cases with a fracture of the anterior or anteromedial facet of the coronoid process were treated by coronoid fixation using a figure-eight suture loop.
- All 11 fractures were united at final follow-up with no joint incongruity, dislocation, or subluxation of the injured elbow.
- The figure-eight suture pattern technique is an easy and effective technique to fix anterior or anteromedial facet fractures of the coronoid process.

PurposeSufficient fixation of an anterior or anteromedial facet fracture of the coronoid process in fracture-dislocation of elbow is important to maintain joint stability. The purpose of this study was to report our experience with 11 patients who were managed with an original fixation technique using a “figure-eight” suture loop.MethodsFrom February 2010 to March 2011, 11 cases with a fracture of the anterior or anteromedial facet of the coronoid process were treated by coronoid fixation using a figure-eight suture loop. For cases with comminuted fractures, to prevent a suture from sliding into the fracture line, a 3- or 4-hole phalanx plate was enclosed in the suture loop to compress multiple fragments. Accompanying injuries, such as a radial head fracture or olecranon fracture, were fixed with repair of lateral collateral ligament injuries.ResultsOn final evaluations at an average of 18 months after injury, the mean elbow arc of motion was 125.5° and the mean forearm rotation arc of 124.1°. All fractures were united with an average postoperative score according to the Mayo Elbow Performance Index of 91 points. All patients achieved satisfactory scores (seven excellent, four good). All 11 fractures were united at final follow-up with no joint incongruity, dislocation, or subluxation of the injured elbow.ConclusionsThe figure-eight suture loop technique is an easy and effective technique to fix anterior or anteromedial facet fractures of the coronoid process.
