The purpose of this study was to apply this new imaging technique to the diagnosis of small partial-thickness rotator cuff tears and to determine how small of tears could be detected with this imaging technique. Methods: Seven supraspinatus tendons excised from embalmed cadavers were used. Three different sizes of partial-thickness bursal-sided tears (1, 3, and 5mm3) were created in each specimen. The intersection of two co-focused ultrasound beams of slightly different frequency was swept across the intended imaging area. The acoustic emission data were collected and used to form and display a vibro-acoustography image of the tendon. Vibro-acoustography images were read by two orthopedic surgeons. Results: The rotator cuff tear could be detected by vibro-acoustography in all specimens. The diagnostic concordance rate was 90.5% and the kappa coefficient value was 0.88, which resulted in a high concordance. The diagnostic concordance rate for the 1mm tear was 71.3%, which was low concordance (κ=0.481), whereas that for the 3 and 5mm tears was 100%. Conclusions: We were able to detect a 3-mm tear by using vibro-acoustography. There is a possibility that this new imaging technique could become a useful imaging tool for the diagnosis of small partial-thickness rotator cuff tears.
