Abstract

The problem of improving the health care of patients with injuries of the musculoskeletal system every year is becoming increasingly important due to the number of casualties and the levels of disability from injuries in people of working age. The aim of our research was to demonstrate that Dual-Energy Computed Tomography with Rapid kV-Switching (DECT, discovery 750 HD, GE Healthcare) could be used for the callus maturity evaluation and to develop accurate criteria for the effectiveness of reparative regeneration and determine the bone fixation time. The study included 18 patients aged from 18 to 55 years with open diaphyseal tibia fractures, all treated with extrafocal transosseous osteosynthesis. The patients were divided into two groups: those treated with the contact ultrasound regeneration stimulation and control group with no additional treatment. All patients underwent dual energy CT to evaluate treatment result. The callus calcium concentration was quantified with DECT to detect signs of delayed consolidation. Studies shown that calcium concentration is better indicator of the fracture consolidation and well correlates with the clinical test of supporting ability. The calcium concentration 260 mg/cm3 and above can be accurate indicator of the callus maturity and an indication for removal of external fixation. The use of contact ultrasound in the treatment of open tibial fractures promotes rapid regeneration of bone fragments.
