[Analysis of treatment results of humeral lateral condyle fractures in children].

Abstract

On the basis of 60 cases authors analyze treatment results of the humeral lateral condyle fractures in children. This type of fracture is a second most common elbow fracture in children after supracondylar fracture of the humerus. Authors consider this fracture to be the most difficult to diagnose among all elbow injuries. Analyzed cohort of patients consists of 54 at age between 1.5 to 10 years and 6 patients between 12 to 17 years of age. In 75% of cases operative treatment was delayed due to late referral from other hospitals. According to appearance of the fracture line on X-rays there were 53 cases of type II and 7 cases of type 1 according to Milch classification system. The amount of displacement was evaluated according to Jakob scale and there were 35 cases of III degree, 17 cases of II degree and 8 cases of I degree of displacement. All patients were evaluated with antero-posterior and lateral distal humerus x-rays. In some cases other diagnostic techniques were used. In older children computerized tomography and in younger children ultrasound examination was performed. The treatment results were evaluated according to Hardacre scale. Follow-up time was 1 to 13 years. There were 27 very good and 27 good results in a 54 cases group of patients who underwent surgery within 15 days since injury. In other group which consists of 6 patients who underwent surgery more than 5 weeks after injury there were 2 cases of very good, 2 cases of good; and 2 cases of bad results. Authors believe that putting a proper diagnosis of humeral lateral condyle fracture in children and performing an operative treatment results in a good and a very good outcomes. Basing on the analysis of treatment results of authors cohort of patients, they claim that precise diagnosis and proper determining of degree of displacement increases the number of patients qualified to operative treatment.
