Abstract PDF: PURPOSE
Because the prognosis of the mid 1/3 clavicle fracture is good, the conservative treatment with a figure of 8 bandage is the gold standard and the nonunions are rare.However, recently surgical treatment is recommended when the shortening and displacement is severe because of the high nonunion rate and the poor clinical result. This study was undertaken to evaluate that the shortening and displacement at fracture site are associated with the development of nonunion.
MATERIALS AND METHODS
We analysed the 194 fractures of mid 1/3 clavicle in adults which had been treated conservatively from February 1993 to January 2002 and did the retrospective study. Of these, 78cases were originally in the middle third of the clavicle and had been completely displaced. We reviewed 63 of these cases. The shortening and displacement at the fracture site was measured on the initial roentgenogram. And the analysis of the patients 'chart was done for another predisposing nonunion factors. Nonunion and delayed union are considered to be present when there has been little or no progression of clinical or radiographic healing at a minimum of 4 months after injury.
RESULTS
15 of the 63cases had developed nonunion.. The average 8.6mm(2mm-17mm) shortening and average 9.7mm(2-22mm) in the union patients. The average 14.5mm(3mm-37mm) shortening and average 17.3mm(4-25mm) in the nonunion patients. We found that initial shortening > or =1 8 m m ( Fisher's exact test, p <0.01) and initial displacement > or =16mm(Chi-square test, p <0.01) at the fracture site were siinificantly associated with the development of nonunion.
CONCLUSION
The conservative treatment with figure-8-bandage is the gold standard in the clavicle middle one third fracture. However, the nonunion is commonly occurs in the cases of more of severely shortened and displaced fractures. If there are no signs of callus formation and the patient complains of pain after several weeks, osteosynthesis should be considered.

Treatment of Supracondylar Fractures of the Humerus in Children: Duk Yong Lee, Jae Ik Shim, Taek Seon Kim, Sung Jong Lee, Suk Ha Lee, Dong Ki Lee, Yoen Sik Yu, Young Jin Park; J Korean Soc Fract 1999;12(1):179-186. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.179

The supracondylar fracture of the humerus is the most common fracture of the elbow in children and is occasionally associated with significant residual complications such as cubitus varus deformity. Clincal analysis was performed on 32 patients with displaced supracondylar fractures of humerus, who were treated either by closed reduction and percutaneous pinning or by open reduction and internal fixation. The results were as follows : 1. The average age of the children was 6.8 years old in both sexes, and male to female was 21 : 11. 2. The extension type was 26 cases(82%), flexion type was 6 cases(18%) and the left side was more frequently involved. 3. According to Pirone classification, type II was 14 cases, type III 18 cases. 4. There was no significant difference in the mean duration of bony union between the percutaneous group and the open reduction group. 5. Cubitus varus deformity and limitation of elbow motion were more common complications in open reduction group.
