  "abstract": "Objective. To investigate and compare the recovery of shoulder girdle muscle function following metal osteosynthesis of displaced fractures of the clavicle body (type 15.2AB according to the AO/ASIF classification) using a compression rod, a contoured LCP plate or a Bogdanov rod, based on electromyography data.\n\nMaterials and methods. In 30 patients with displaced fractures of the clavicle body classified as type 15.2AB according to the AO/ASIF classification, the recovery of upper limb muscle function was assessed over a 1-year period following metal osteosynthesis using an LCP contoured plate, a compression rod and a Bogdanov rod, the recovery of upper limb muscle function was assessed using electromyography. Patients were examined on the 30th day, and 3 and 12 months after surgery. The functional status of the upper limb muscles (deltoid, pectoralis major, infraspinatus and trapezius) of the operated limb was assessed and compared with the functional status of the corresponding muscles of the shoulder girdle on the healthy limb using surface (interferential) electromyography on the M-TEST 2 device (DX-Systems, Ukraine). The bioelectrical activity of the muscles was assessed using the following parameters: maximum amplitude, mean spectral frequency and asymmetry coefficient. The data obtained were interpreted using licensed software from DX-Systems (Ukraine).\n\nResults. Analysis of the early rehabilitation period (1 month post-operation) revealed the advantages of metal osteosynthesis of displaced clavicle shaft fractures using a compression rod: the maximum amplitude of the deltoid muscle was (290.2 ± 14.3) μV. The results of metal osteosynthesis of clavicle shaft fractures using a contoured LCP plate and a Bogdanov rod were poorer: the maximum amplitude values of the deltoid muscle were (220.4 ± 15.1) and (235.5 ± 16.8) μV, respectively (p < 0.05). By the third month of the rehabilitation period, a ‘critical point’ was identified in relation to metal-osteosynthesis of clavicle shaft fractures using a Bogdanov pin: the subscapularis muscle deficit was (210 ± 19.2) μV and was the highest (p < 0.05) among the corresponding values when other methods of metal osteosynthesis were used. Twelve months after metal osteosynthesis of clavicle shaft fractures using a contoured LCP plate and a compression rod, good, practically adapted function of the shoulder girdle muscles was established based on the maximum amplitude and average frequency of the spectrum. In contrast, in patients who underwent metal osteosynthesis of clavicle shaft fractures using a Bogdanov rod, incomplete adaptation of the shoulder girdle muscle function was observed. The maximum amplitude and mean frequency of the spectrum for the subscapularis muscle were , (340.1 ± 24.5) µV and (68 ± 3.1) Hz respectively; that is, they were low, which objectively indicated its atrophy.\n\nConclusions. Following intramedullary metal osteosynthesis of displaced clavicle shaft fractures using a compression rod, electromyography data indicate that the conditions for early recovery of upper limb muscle function are better than after metal osteosynthesis using a contoured LCP plate and a Bogdanov rod.",
