Stability and quality of osteosynthesis in treatment of tibial pylon fractures with dynamic external fixation typ Mitkovic

The study included 35 patients with fractures of distal tibia treated at the department of orthopedics HC K. Mitrovica and the Orthopedic clinic in CHC of Nis by a dynamic external fixator fixation of ancle. Ovadia-Beals score was used to assess the quality and repositioning and to assess the stability assessment made osteosynthesis. The final functional result of treatment the patient was determined based on the AOFAS score. Deviations for postoperative talocrural angle for extraarticular fractures was approximately 6 degrees (excellent result). Student's T-test showed statistically significant difference (t = 1.693 p < 0.05) before and after surgery in favor of a postoperative series in the analysis of articular fractures by Ovadia-Beals score, and that means much better anatomical conditions for healing. Student's T-test were not found statistically significant differences in postoperative radiographic parameters in postoperative series and series before removing fixator for the extraarticular and intra-articular fractures, for extraarticular fractures (t = 1.440, p > 0.05), and intrarticular fractures, (t = 1.234, p > 0.05), which is a remarkable result and describes the remarkable stability of the fracture zone by this method. Distribution of complications: soft-tissue complications of 11.4%, healing in a bad position of 5.7%, nonunions 3%, infection 6%. Distribution of functional results according to AOFAS score: excellent 27.2%, good 40%, satisfactory 11.4% 11.4% bad. Pearson's test (r = - 0.6002) has been shown that the weight of the fracture is correlated with the AOFAS score, or the level of the outcome of treatment decreases with the increase cominution of fracture zone.
