STATEMENT OF ETHICAL APPROVAL AND ETHICAL STANDARDS
All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards.
The Department of Clinical Investigations Institutional Review Board at Tripler Army Medical Center approved this study as IRB exempt.
Statement of Clinical Relevance:
When measuring anterior glenoid bone loss, evaluation of CT with 3D reconstruction is more reliable than MRI. Furthermore, the Area Measurement Percentile method has the greatest interobserver reliability when compared to Linear Measurement Percentile method and Circle-Line method.
