Objective. To improve the treatment results of the tibia diaphysis fracture by the designed device for intraosseous interlocking osteosynthesis.
Methods. It was a non-randomized controlled trial. There were two groups of patients (n=163): the main group (n=41) who underwent the fracture treatment by the designed device; the control group (n=122) who were treated with the ChM interlocking nail. The groups were comparable in age (p=0.066), sex (p=0.824), fracture level (p=0.659), type of injury (p=0.189) and fracture type (p=0.566). Preoperative and postoperative patients management was identical.
Results. The period of disability to work in the main group (M=62.8; Me=63.0; IQR=11 days) was shorter than in the control group (M=87.4; Me=82.0; IQR=28 days) (p<0.001). Also, higher weight bearing ability at the time of discharge (M=45.7 vs. M=33.0); and 1 month after the operation (M=90.9 vs. M=86.5) and earlier time for restoration of ability to walk without crutches (M=29.3 vs. 64.9 days) were registered in the main group vs. the control (p<0.001; p=0.018; p<0.001 respectively). At the same time, the number of inpatient days in the groups did not differ statistically (17.4 days in the control vs. 18.1 days in the main). There was not statistically significant difference in weight bearing ability at terms of 3 months after surgery (in both groups it reached 100%, p=0.059); number of complications (p=0.369); presence of shortening (p=0.149); treatment outcomes (p=0.849).
Conclusions. In this study, the designed expandable nail for interlocking osteosynthesis of the tibia shaft fracture enabled faster recovery of the patients ability to work. At the same time, for such parameters as inhospital stay, the presence of shortening and complications, the outcome of the treatment, the designed nail was not worse than the standard ChM nail.
