Methods Thirty-eight cases were treated with the self-made Kirschner with saw, the diameter of 1.5 mm. To observe and analyse the clinical effect in the healing of the bone, the improvement of the carrying angle, the function of the elbow and the complications. Results All the patients were followed up 6 months to 3 years.The areas of the cut bone healed without injuries of nerve, vascular and epiphysis. The carrying angle recovered from 8° to 15° (mean 13.5°). During the follow-up, there were no lost of the carrying angle and no herniation of external condyle of humerus and no statistical difference in appearance.According to Cassebaum marking standard, there were 29 cases excellent,8 cases good, 1 case fair, with good rate of 97.37%(37/38). Conclusions The new technique is micro-traumatic,safe and easy to operate.It is an ideal treating method and worthy of clinical application.
