EVALUATION OF TREATMENT OUTCOMES FOR PROXIMAL HUMERUS FRACTURES USING LOCKING PLATES BASED ON PREOPERATIVE 3D RECONSTRUCTION AND 3D PRINTING

Tóm tắt

Background: Proximal humerus fractures are among the most common injuries, accounting for approximately 4-5% of all fractures, particularly prevalent in the elderly. Treating complex fractures, especially those with significant displacement, remains a challenge for orthopedic surgeons. The use of locking plates has been proven effective due to their ability to provide stable fixation and support anatomical recovery. However, accurate preoperative surgical planning plays a crucial role in ensuring optimal treatment outcomes. With advancements in 3D reconstruction and printing technology, personalized treatment planning has become more feasible than ever. This study aims to evaluate the treatment outcomes of proximal humerus fractures using locking plates based on preoperative 3D reconstruction and printing. Objectives: To comment on the characteristics of proximal humerus fractures on conventional X-ray and CT scan with 3D reconstruction and printing, evaluate the surgical outcomes of proximal humerus fractures treated with locking plate fixation. Materials and method: A cross-sectional descriptive study was conducted on 59 patients with proximal humerus fractures who underwent CT scan with 3D reconstruction and printing before surgery. The surgery was performed based on the evaluation of 3D-printed models. Postoperatively, patients were followed up for 6 months and assessed based on clinical outcomes, postoperative X-ray imaging, and shoulder joint functional recovery (according to the Constant-Murley score). Results: The average age was 56.3 ± 13.045 (23-83) years, and the age group of 40-60 years accounted for 44.1%. The majority of cases (76.3%) were classified as Neer III. Surgical time under 60 minutes accounted for 69.5% of the total cases. The majority of patients achieved excellent shoulder joint functional recovery, representing the highest proportion (78%). Conclusion: The study demonstrates that the use of 3D reconstruction and printing technology before surgery offers numerous benefits in the treatment of proximal humerus fractures using locking plates. This method improves surgical accuracy, reduces surgical time and complication rates, and enhances shoulder joint functional recovery.
