Summary

To predict the prognosis of large-to-massive RCTs and risk of re-tear by ultrasound elastography.

Detailed description

Most symptomatic large-to-massiverotator cuff tears (RCTs) should be operated, but the prognosis and postoperative risk of re-tear depended on the quality of rotator cuff muscles. Preoperative evaluations were usually done by magnetic resonance imaging (MRI). MRI was used in recent studies to predict the surgical outcome of large-to-massive RCTs and postoperative re-tear, but the clinical availability was not as good as ultrasound. The investigators hypothesize that ultrasound elastography can predict the prognosis of large-to-massive RCTs and risk of re-tear.

Conditions

• Rotator Cuff Tear

Interventions

Type	Name	Description
OTHER	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.
