Summary
The purpose of this study is to evaluate the clinical results of Dog Bone Button for distal clavicle fractures. 19 cases who were followed up over 6 month. 17 cases had union. All cases were pleased with their cosmetic results. The functional outcome is acceptable in most case of this procedure. This surgery was a minimum invasive technique and the clinical results was satisfied.

Abstract
Treatment of distal clavicle fractures is controversial. The Neer type II distal clavicle fracture is notorious for its high nonunion rate, and surgical treatment is usually recommended. Some procedures for these fractures show good results but excellent results. Now we do not have the best method for this. Oh (2011) describes tension band wiring and hook plate has high complication rate and nonsurgical treatment has high nonunion rate.
The purpose of this study is to evaluate the clinical results of Dog Bone Button for distal clavicle fractures. 19 cases (male 15, female 4, 48.6 y.o. ) who were followed up over 6 month were evaluated in this study.
Post-operative rehabilitation was no sling, no limited IR and ER. Abduction and flexion were limited to 90 degree three weeks after operation. X-ray was check every months after operation, finally CT was used to confirm union 3 and 6 month after surgery.
Of 19 cases, 17 cases had union of fractures (89.5%). 3 month after surgery, VAS is 5.0±8.0mm, constant score is 77.6±.7.6, Flexion is 161.6±16.7 degree, abduction is 164.7±18.8 degree, external rotation is 51.3±13.6 degree, internal rotation is 77.6±3.6 degree. 6 month after surgery, VAS is 3.0±0.7mm, constant score is 82.3±7.4. Flexion is 162.4±15.1 degree, abduction is 164.5±18.4 degree, external rotation is 55.3±12.4degree, internal rotation is 75.6±12.6 degree. All cases were pleased with their cosmetic results.
The functional outcome is acceptable in most case of this procedure, and it is possible to get high union rate. Although this surgery was a minimum invasive technique and the clinical results was satisfied, it is necessary to achieve the skill for this operation.
