Purpose: Rotator cuff tears (RCTs) are common upper extremity injuries the incidence of which continues to rise [1]. Small and medium-sized RCTs usually treated with nonsurgical management initially, while massive tears are the subject for primary surgery.   Despite the development of arthroscopic [...]

Methods and materials: Patient characterization 29 pts: (11 female +18 male) with shoulder pain and disability underwent US with and without SE before MRI study. 18 cases involved the right side and 11 cases the left side. 17 cases involved the dominant arm and 12 cases the nondominant arm.   There were 6 full[...]

Results: For SSM atrophy US SE had a positive correlation (r = 0.829, p =<0.001), without SE (r = 0.679, p =<0.05) with reference to MRI. For FD grades US SE also had a positive correlation (r = 0.873, p =<0.001), US alone (r = 0.713, p =<0.05) with reference to MRI.   Conventional grey sc[...]

Conclusion: US with SE had excellent interobserver reliability and better correlation with MRI findings than conventional ultrasonography for SSM atrophy and FD. Fusion technology improves understanding of shoulders anatomy enlarges the FOV of US image, thus providing more accurate measurements and could[...]
