مقایسه دو روش درمانی جااندازی بسته و پین گذاری و جااندازی باز درشکستگی سوپراکندیلار نوع III استخوان بازو در کودکان زیر ده سال

Background : Supracondylar fractures of the humerus comprise the most common fracture in children. Two-thirds of children, who are hospitalized due to arm injury, are infected by Supracondylar fractures. The aim of this research is to investigate two treatment methods, "close reduction and external fixation with pin" and "open reduction and internal reduction in Supracondylar fractures. Materials and Methods: This clinical trial study was conducted in Ayatollah Kashani hospital, Sharekord, Iran in 2010. Ninety patients with suppracondilar fracture type III were selected and through Random Number Table allocated in two groups. The first group cured by close reduction and external fixation with pin through C-arm control and the second group were cured by open reduction and subcutaneous pin and internal fixation and then underwent surgery through posterior fixation. The patients, information including the duration of operation, radiography, wound infection, treatment cost, and the rate of movement area of elbow in the eighth week post operation were collected. The data were analyzed using chi-square and t-test tests. Results: There was no significant difference between two groups in terms of age, gender, urban and rural place of residence, fracture side and arm fracture. After the first week of operation, 3 patients (6.66%) operated by open reduction and one patient (2.22%) operated by closed reduction were infected (P<0.05). The mean of elbow movement 8wecks after operation was 118.3±10.9 in opened group and it was 131.5±10.5 in close group grade (p<0.001). The mean of operation time and operation cost was significantly more in the open group than the close group (P<0.001). Conclusion: Based on the results of this study, the frequency distribution of postoperative complications, cost, hospitalization duration in the close group was lower than the opened group and more effective in suppracondilar fracture treatment. This method was prescribed for treatment of humerus fractures.
