Abstract

The purpose of this study is to defiene an available period of delay in treatment which can be expected a favorable outcome despite a loss of adequate initial treatment in the fractures of humeral lateral condyle in children. We retrospectively evaluated 17 cases who had late presentation of humeral lateral condylar fractures in children. Average age was 4 years and I month. There were 13 boys 4 girls. As for Milch type classification at initial trauma, there were 2 cases (11.8%) of type I and 15 cases (88.2%) of type Ⅱ. According to Jakob's staging of displacement ant initial trauma, all cases were stage Ⅱ that I case showed less than 2mm displacement and 16 cases showed more than 2 mm displacement. Sixteen caces showed further displacement during early conserative treatment, I case was overlooked at initial diagnosis. Average time until to visit our hospital after trauma was 19.5 days. The mode of treatment were closed reduction with K-wire fixation in 6 cases, open reduction with K-were fixation in 10 cases and long arm cast in 1 case. Average time of postoperative immobilization was 3.7 weeks. Clinical results were excellent in 15 cases and good in 2 cases. Postoperative complication was not found. In late presentation of humeral lateral condylar fracture in children, open or closed reduction wiht internal fixation may promise a favorable outcome in patients treated by 5 weeks after trauma.
