Variation in Acromioclavicular inclination angle in coronal plane and it’s implication in Tension Band wiring for fracture distal end of clavicle

Abstract

Background: Implant failures of trans Acromion fixation in case of displaced distal end of 
clavicle fractures are common due to the variation in anatomy of Acromioclavicular joint. 
And also variations in Acromion morphology widely studied. Objectives: To study the 
coronal angulation of Acromioclavicular in X-rays and correlate with types of Acromion and 
to study the available lateral part of clavicle for fixation with trans Acromion pins Methods: 
We measured the angle of coronal inclination between Acromion and Lateral clavicle and 
grouped them according to Acromion types. Also we measured the maximum possible length 
of lateral clavicle available for k wire fixation.
