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 techniques,
clinical success rates in treating RCTs have remained relatively constant.
Many factors contribute to the success of a rotator cuff repair.
Muscle quality appears to have a major role in determining clinical outcomes [2].
Massive tears have been found to be associated with atrophy,...
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 and11 cases the left side.
17 cases involved the dominant arm and 12 cases the nondominant arm.
There were 6 full thickness rotator cuff tears,
9 partial thickness rotator cuff tears,
11 rotator cuff tendinopathy,1 adhesive capsulitis,2 calcific tendinitis.
Shoulder MRI protocol
MRI of the shoulder was reformed on GE Signa HDx 1.5 Tesla with a shoulder...
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 scale UScould not clearly differentiate muscle from the fat in 6 cases of 9 partial tears,
because the echogenicity was equal.
US SE improved the diagnosis of fatty degeneration and atrophy in...
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 FOVof US image,
thus providing more accurate measurements and could be helpfull in the follow-up tool for shoulder injuries.
