[Closed reduction and three Kirschner pin fixation at the radial side for the treatment of supracondylar fracture in children with Gartland type II and type III].

OBJECTIVE

To investigate the characteristics of supracondylar fracture of humerus in children and to explore the effect of closed reduction and internal fixation at radial side on the fracture.

METHODS

The children with fractures of Gartland type II and type III in our hospital from June 2010 to June 2013 were reviewed. There were 28 males and 7 females, ranging in age from 1 year and 1 month to 2 years and 6 months, with an average of 2 years and 1 month. According to Gartland classification, 19 cases were type II, 16 cases were type III. There were 3 patients with radial nerve injuries, and 5 patients with anterior interosseous nerve injuries. There were no vascular injuries. All the patients were treated with closed reduction and three Kirschner fixation at the radial side, followed by the plaster external fixation with elbowed flexion at 90 °. The X-ray examination was performed at the second day after operation. The joint function exercise began about at 2 to 3 weeks after operation when the plaster fixation was removed, and opportune time for removal of Kirschners depends on the situation of fracture healing. The operation time, nerve recovery, and the elbow joint function were observed.

RESULTS

All the children were followed up, and all the fractures had bony union. According to Flynn score system at the final follow-up, 28 patients got an excellent result, 4 good, 1 poor and 2 bad.

CONCLUSION

Three Kirschner fixation at the radial side for the treatment of supracondylar fracture of humerus has advantages of minimally invasive, shorter time of hospitalization, simple removal of the internal fixation and reliable therapeutic effects.
