Clavicle fractures are common, yet debate exists regarding which patients would benefit from conservative versus operative management. Traditionally shortening greater than 2cm has been accepted as an indicator for surgery. However, clavicle length varies between individuals. In a cadaveric study clavicle shortening greater than 15% was suggested to affect outcomes. There is no clinical correlation of this in the literature. In this study we investigate outcomes following middle third clavicle fractures and the effect of percentage shortening on union rates. We identified a consecutive series of adults with primary midshaft clavicle fractures presenting to our institution from April 2015-March 2017. Clinical records and radiographs were reviewed to elicit outcomes. Time to union was measured against factors including; percentage shortening, displacement, comminution and smoking. Statistical significance was calculated.Abstract
