OSTEOSYNTHESIS OF THE PROXIMAL END OF THE HUMERUS USING CLAMPS WITH THERMOMECHANICAL SHAPE MEMORY

Abstract

The problem of surgical treatment of fractures of the proximal end of the humerus is one of the most pressing in traumatology and orthopedics.
Proximal humerus fractures account for 80% of all humerus fractures. For fractures of the proximal end of the humerus, various types of osteosynthesis are used, using various plates, intraosseous rods, screws, knitting needles, metal forks, wire loops, etc. These fixators, as a rule, cannot provide sufficiently strong osteosynthesis of the proximal end of the humerus, and therefore,after operations, additional external immobilization of the damaged limb is carried out with plaster casts and scarves, especially in elderly and senile patients.
In surgical practice, it is known to use metal structures and implants made of material with thermomechanical shape memory, the advantage of which is the high biocompatibility of the materials, good fixation, providing compression for the entire period of treatment, and the fact that repeated operations to remove these metal structures are not required.
The experience of surgical treatment of injuries of the proximal end of the humerus with fixators with thermomechanical shape memory is presented, 6 patients with fractures of the proximal end of the humerus with displacement of fragments, the age of the patients ranged from 15 to 72 years, in our trauma department of the Clinical Emergency Hospital in the period 2023-24. Of the 6 patients monitored, we received positive results as excellent, good, satisfactory in 5 (83.4%) patients, and in 1 (16.6%) as an unsatisfactory result of the treatment.
