Objectives: The treatment of ulnar coronoid process fracture is a difficult problem in orthopedic trauma. The purpose of this study is to study the clinical effects of different methods to fix the coronoid process fracture, so as to better guide the clinical work. To study the clinical efficacy of loop plate technique in the treatment of Regan – Morrey 1 and 2 type ulnar coronoid process fractures, and to compare the clinical efficacy of loop plate technique, mini-plate screw fixation technique and non-surgical unfixed method in the treatment of Regan – Morrey 1 and 2 type ulnar coronoid process fractures.

Methods: Retrospective analysis and control study were used to study the cases of Regan Morrey type 1 and type 2 ulnar coronoid process fractures hospitalized in the Department of Traumatology and Orthopedics of Xi'an Honghui Hospital from June 2019 to June 2022. A total of 48 cases were included according to the inclusion and exclusion criteria. According to different treatment methods, they were divided into loop plate technology group (31 cases), mini-plate screw group (10 cases), and non-surgical unfixed group (7 cases). The patients were followed up for 3 months to 1 year to evaluate the reduction of fractures after surgery Fracture healing, complications, elbow joint range of motion, and Mayo elbow joint function score. The clinical effects of different fixation methods were compared.

Results: Of the 31 cases in the loop plate technique group, 28 cases achieved anatomical reduction without loss of reduction, and all achieved osseous healing. Among them, 3 cases had complications, with an average elbow joint range of motion of 19.37 ° - 11.3.97 °. The MEPS function score of the elbow joint was excellent in 27 cases and good in 4 cases. The comparative analysis of the curative effect of the three groups showed that there was no significant difference in fracture healing between the three groups (P>0.05). There were statistically significant differences between the anatomical reduction, reduction loss, postoperative complications, elbow flexion and extension activity at the last follow-up, and elbow function score at the last follow-up.

Conclusion: After the mid-term follow-up, the clinical case-control study showed that the treatment of Regan - Morrey 1 and 2 type ulnar coronoid fractures with loop plate technique had good curative effect, high anatomical reduction rate of fracture, good fracture healing, low postoperative complication rate, good elbow joint mobility after operation, and the clinical effect was better than that with micro-plate screw fixation and non-surgical unfixed.
