Abstract

Objective: To describe the clinical and X-ray characteristics of humeral head fractures, and the results of treatment with minimally invasive locking screw and bone fusion surgery (MIPO). Research subjects and methods: Retrospective and prospective description of 31 patients undergoing MIPO surgery from January 2020 to December 2023. The average follow-up period was 18 months. Results: 31 patients (19 men, 12 women) with an average age of 52.7 ± 18.1 (18- 84 years old). The main accident mechanisms were traffic accidents (16/31) and daily life accidents, falling and hitting the shoulder (10/31). The rate of A2 fracture is 51.6%, A3 is 9.7%, B1 is 35.5%, C1 is 3.2%. The average surgery time was 57.74±16.27 minutes. The average neck-trunk angle after 1-year follow-up was 135.9 ± 12.6º (97º- 154º). Assessing shoulder joint function according to the Constant-Muller scale: Patients with good and very good results account for 83.6%, average accounts for 16.1%, and no patient has poor results. There were no cases of bone nonunion, infection, screw penetration through the head, humeral head resorption, or axillary nerve paralysis. Conclusion: MIPO surgery can be applied as an effective and safe treatment method for proximal humerus fractures. However, longer intraoperative C-arm imaging time and difficulty in converting to open surgery, if correction fails are issues that need to be considered.
