摘要

In response to the letter by Hengg et al. concerning our article entitled "Area-Based Determination of Bone Loss Using the Glenoid Arc Angle" published in the July 2012 issue of Arthroscopy, we appreciate the clarification regarding the amount of radiation exposure for bilateral shoulder computed tomography. The comments by Hengg et al. bring to our attention the fact that if computed tomography images of the contralateral uninjured shoulder are obtained simultaneously with that of the injured shoulder, no additional radiation is incurred by the patient. Requesting routine reconstruction images from the contralateral/uninjured shoulder for comparison should thus be considered in patients with shoulder instability.
