Summary

Large-to-massive rotator cuff tears accounts for 30% of all rotator cuff tears. These problems can be solved by surgeries, but only part of them can be completely repaired. The prognosis for partial repair is worse than complete repair, so evaluating the possibility of complete repair is so important that it will affect the decision of treatment. More and more recent researches focused on using magnetic resonance imaging (MRI) for evaluation of fatty infiltration of rotator cuff muscles to predict the reparability of large-to-massive rotator cuff tears. However, the availability of MRI is not that good as ultrasound, so some researchers are starting to use ultrasound to predict the reparability of large-to-massive rotator cuff tears. Because it is hard to observe the tissue quality through the general ultrasound, many researchers use sonoelastography to evaluate the tissue elasticity and viability. This aim of this study is to: 1. check the reliability of sonoelastography. 2. associate the findings of sonoelastography to the results of MRI. 3. build a predictive model for the reparability of large-to-massive rotator cuff tears.

Conditions

• Rotator Cuff Tear

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Sonoelastography	This diagnostic test would be executed by a physician who has experiences of using Siemens Acuson S2000 ultrasound system for more than three year. The examination includes two of four rotator cuff muscles, listed as follows, supraspinatus muscle and infraspinatus muscle. Linear transducer (4-9 MHz) would be used for the whole test. The probe would be positioned along the longitudinal axis of the muscle belly. Compressive sonoelastography technique is used for semiquantitative analysis. In order to maintain the quality of images, quality factor needs to be over or equal to 60. The quantitative analysis was performed by shear wave sonoelastography and the region of interest (ROI) would be divided into four quadrants. The physicians will measure the shear wave velocity at the center point of each quadrant.
