DEVELOPMENT OF A DEVICE FOR THE SURGICAL TREATMENT OF THE PROXIMAL HUMERUS FRACTURES. CONDUCTING A BIOMECHANICAL EXPERIMENT.
Introduction. Proximal humerus fractures account for 5–10% of all fractures of the musculoskeletal system. Many methods of surgical treatment of the proximal humerus fractures are described in the world literature, but there is still no generally accepted standard. According to the above information, the invention of new types of implants and various surgical methods to improve the results of proximal humerus fractures surgery is still continuous.
Aim. To develop a new device for stable and functional osteosynthesis of the proximal humerus fractures.
Materials and methods. A new device for osteosynthesis of proximal humerus fractures was invented. The biomechanical study was carried out in the “bone-fixator-bone” system, to check the stability of osteosynthesis of the proximal humerus fracture by the developed device. A total of 4 Humerus humerus models, 4th Gen., from “Sawbones”, were used. A surgical neck fracture was made and compression tests were performed at a speed of 5 mm/min and torsion tests at a speed of 50/min in static load mode.
Results. When studying two models of the humerus in the “bone-fixator-bone” system for compression, the average maximum load was 1105.35 Newton, the average displacement of fragments under the above load was 1.61 mm. When studying two models of the humerus in the “bone-fixator-bone” system for torsion, the average maximum load was 16.22 Nm, and the average angle of displacement of the fragments at the above load was 48.970.
Conclusion. The biomechanical study proved the stability of osteosynthesis of the proximal humerus fracture using the developed device. The study did not include a control group, and therefore further finite element computer simulations should be performed to include a control group with a standard locking plate.
