Modern methods of Х-ray diagnostics allow quantitatively analyzing the structures of the musculoskeletal system. Biomechanical aspects of functional activity in the perioperative period depends on muscular morphology and its result in postoperative functional outcome. The objective is to determine the area and density of the large lumbar muscle (LMB) on the side of the lower limb after hip arthroplasty (HA). Material and Methods. The cross-sectional area and BPA density on both sides were measured by computed tomography (CT) at the level of the third lumbar vertebra in 327 patients after single TBS endoprosthesis 6 and 12 months after surgery. The mean values of BPM density and area were lower 6 months than 12 months after the surgery though they were significantly lower than normal values. Microsoft Office Excel and SPSS Statistics (StatSoft, USA) are used to statistically analyse the results obtained. The data presented with the standard deviation (SD) and mean value are considered statistically significant at p < 0.05. Results and Discussion. A significant asymmetry in the morphology of skeletal muscles including the iliopsoas and calf muscles is observed in durable osteoarthritis. Conclusion. Morphological assessment of the BPM by CT is important in terms of the rehabilitation potential as it significantly affects the quantitative parameters of functional activity.
