Objectives: Supracondylar humeral fractures account for two thirds of all elbow fractures in children. Frequeng treatment complication of this fracture type is varus deformity of the elbow. The aim of this study was to establish whether there is, and in what extent, bone remodelling of humerus at the spot of treated supracondylar fractures in children, as well as to determine its influence on the possibility of correction of the remaining deformity and final treatment results. Patients and methods: A group of 93 children with an average age of 6,3 years with supracondylar humeral fracture Gartland type II and III was followed during 6,4 years. Their treatment combined fracture reduction, Kirschner wires fixation and immobilisation. Elbow radiograms were done after the trauma, at the end of the treatment and at the follow-ups. Baumann and carrying angles of the injured and healthy arms were measured on the radiograms, and by their comparison the appearance and the extent of bone remodellation were questioned. Elbow movement was measured by goniometre. Efficiency of the treatment was analysed using the Flynn's method. Results obtained were processed statistically. Results: Average value of the Baumann angle of the injured arm on the final follow-up was significantly higher than the one after the treatment. The difference in these angle values is a proof of bone remodelling development. In 60,9% of examinees there was significant increase of Baumann angle, when comparing to 31,9% of examinees which had a decrease of the angle, as well as to 7,2% of examinees which showed no change of the angle. There was remodelling in 92,8% examinees. The value of bone remodelling when the anglewas increased came to an average of 4,24º, and in cases of its decrease to 2,59º. Average carrying angle value of the traumatised arm at the final follow-up was significantly lower when comparing to the values of the same angle of the healthy arm which suggests clinical development of varus of the elbow. Flynn's method testifies that the treatment was sucessful in 93,6% of examinees. Conclusion: There is bone remodelation on the spot of supracondylar humeral fracture in children. The extent of bone remodellation is low and without significant influence on the possibility of correction of the remaining deformity of humerus and final treatment results.
