Objective: Although ulna coronoid process fracture is uncommon, it is a complex injury and its treatment remains difficult. This study assessed the clinical efficacy of loop plating technique, a potential method to treat ulna coronoid process fracture. Materials and Methods: Seven cases of ulna coronoid process fractures treated with loop plating technique from October 2012 to May 2015 were analyzed retrospectively. Patients' age ranged from 18-55 years (mean age 36 years). All cases were closed fractures. X-ray and 3D computed tomography were applied to all patients before surgery. After anteromedial incision, a homemade loop plate was fixed after satisfactory reduction of fractures. Lateral collateral ligament injuries were repaired and reconstructed in 4 cases and medial collateral ligament injury was repaired in 1 case during surgery because of elbow instability. Functional evaluation data were collected and analyzed statistically. Results: No patients suffered from delayed incision healing, redisplacement, fixation failure, or elbow joint instability. At last follow-up, mean Broberg and Morrey score was 94.1, Mayo Elbow Performance Index was 92.1, Ewald scoring system was 88.6 and Disabilities of the Arm, Shoulder and Hand score was 5.4. During follow-up, only 1 patient had elbow heterotopic ossification (grade I-II). Conclusion: Application of loop plating technique might be a valid method for treatment of ulna coronoid process fractures, including various fracture styles, especially for comminuted fractures, but excluding simple coronion fractures of ulna coronoid process.
