Treatment of bone defects of tibia edge during external anchorage of fragments

Abstract

The aim: to identify the efficiency of the improved technology of treatment of tibia marginal defects with the use of granular composite osteoplastic materials during external fixation of fragments. Material and Methods. The observation group was made up of 12 patients with the consequences of lower extremity traumas who had undergone osteosyn-thesis of fractures by an external fixation device with defect alloplasty We used clinical and ray-tracing testing methods and also standardized system of assessment of outcomes of bone fractures and their consequences to control the processes of restoration of bone structure integrity. Results. According to the standardized system of assessment of outcomes in 12-18 months in the course of the rehabilitation measures degree of restoration of anatomic functional indices was 92±5%. Bone density made up 91,3±0,54 HU (p<0,05) before surgery according to the Hounsfield scale, increase in the given parameter was observed in a month and a half after surgery up to 153,1 ±0,97 HU and in 3 months up to 162,7±0,78 HU. Conclusion. Application of granular composite osteoplastic materials for plastic surgery of tibia marginal defects during external fixation of fragments allow us to carry out anatomic reconstruction of the bone reducing surgery injury rate based on the absence of necessity of taking autogenous tissues from the other zones.
