Post-mortem ultrasonographic assessment of the anterior glenoid labrum.
OBJECTIVE
The purpose of this study was to investigate the identification of the anterior glenoid labrum with ultrasonography.


METHODS
Twelve cadaveric shoulders from subjects 74 to 85 years of age were examined by ultrasonography. Under ultrasonographic guidance, a small amount of dye was injected on the structure believed to be the anterior glenoid labrum, whereafter the shoulders were dissected.


RESULTS
In 11 shoulders the dye was found in close relation to the glenoid labrum. Comparing the labrum to a watch face numbered clockwise in the left shoulder, and counter clockwise in the right, the part seen was located between 1 and 5 o'clock. Signs of degeneration were found in six labra by ultrasonography and verified by blindfolded dissection.


CONCLUSIONS
Ultrasonography can identify the anterior glenoid labrum and distinguish degenerated from normal labra.
