| Objective:With the increasingly serious aging society,the incidence of proximal humerus fracture is gradually increasing.In this paper,the clinical efficacy of 3D print-assisted PHILOS plate in the treatment of proximal humerus fracture and the traditional simple PHILOS plate in the treatment of proximal humerus fracture were retrospectively analyzed to discuss the clinical efficacy of 3D print-assisted PHILOS plate in the treatment of proximal humerus fracture.Materials and Methods:The cases selected in this study were from patients with proximal humerus fracture who were hospitalized in the Orthopedics Department of Trauma,China-Japan Union Hospital of Jilin University from December2020 to June 2022,and all of them met the criteria for case selection.A total of 40 cases were collected.The experimental group was treated with 3D print-assisted PHILOS plate for proximal humerus fracture,while the traditional group was treated with simple PHILOS plate for proximal humerus fracture.There were 20 cases in each group.In the experimental group,there were 9 males and 11 females,and the average age was(47.20±11.04)years old.There were 3 cases of Neer II,13 cases of Neer III,and 4 cases of Neer IV.Among them,5 cases were injured by car accident,15 cases were injured by fall,and 8 cases were complicated with underlying diseases.In the traditional group,there were 8 males and 12 females,with average age of(46.35±10.63)years old.There were 2 cases of Neer II,15 cases of Neer III and 3cases of Neer IV.Among them,7 cases were injured by car accident,13 cases were injured by fall,and 9 cases were complicated with underlying diseases.Active preoperative preparation,treatment of basic diseases.X-ray and CT examinations were performed on the affected shoulder.In the experimental group,CT image data was transferred to a 3D printer,and the physical model of fracture was printed at a ratio of 1:1,and the operation drill was performed on the model before surgery.After the operation,the patient was actively treated with symptoms and instructed to carry out timely and correct functional exercise.Radiographs of the affected shoulder were periodically reviewed and the mobility of the shoulder joint was assessed.The functional score of the affected limb was performed using the Constont-Murley scale of the shoulder joint.The operative time,intraoperative blood loss,intraoperative fluoroscopy times,anatomic reduction rate and CM score of shoulder joint 12 months after surgery were carefully recorded in the two groups.All data were processed and analyzed using SPSS26.0 statistical software.Results:Both groups were followed up for 12-18 months.Bone union was achieved in both groups,and no serious postoperative complications such as plate fracture,loosening,non-union or delayed union of fracture and necrosis of humerus head were found.One case of wound skin infection was found in the traditional group after surgery,but after a series of symptomatic treatments such as routine anti-infection and dressing change,the patient also recovered well.In the experimental group,the operative time was(89.95±5.09)minutes,the intraoperative blood loss was(144±9.84)ml,and the intraoperative fluoroscopy was(2.60+0.80)times.In the traditional group,the operation time was(107.50±7.99)minutes,the intraoperative blood loss was(187.70±5.90)ml,and the number of intraoperative fluoroscopy was(4.85±1.14).There were significant differences in operation time,intraoperative blood loss and intraoperative fluoroscopy times between the two groups(P < 0.05).There was no significant difference in anatomical reduction rate of fracture and CM score of shoulder joint 12 months after surgery between the two groups(P > 0.05),with no statistical significance.Conclusion:1.3D printing technology assisted PHILOS plate in the treatment of proximal humerus fracture has more advantages in reducing surgical time,surgical bleeding and intraoperative fluoroscopy times,which can reduce the damage caused to patients during surgery.2.The physical model of fracture printed in 3D enables the operator to simulate the operation before operation,improve the accuracy of fracture reduction and fixation,and can be popularized in clinic. |
