Objective
The aim of this study is to evaluate the accuracy
of magnetic resonance imaging (MRI) in detecting
biceps lesions in patients with rotator cuff tears.
Material and Methods
A total of 168 patients operated on between January
2012 and February 2020 were included in the study.
All the patients underwent arthroscopic surgery
with the diagnosis of rotator cuff tears. All patients
were operated on under general anesthesia and
in the beach chair position. Demographic data and
preoperative MRI findings were recorded. Arthroscopic
findings were accepted as the standard reference and
correlated with preoperative MRI records.
Results
In preoperative images, full-thickness rotator cuff
tears were identified in 118 (70.2%) cases and partialthickness
tears in 50 (29.8%) cases. Labrum/SLAP
lesions were detected in 18 (10.7%) cases. Biceps
disorders were reported in 51 (30.4%) cases. During
the surgeries, we observed additional pathologies in
41 (24.4%) cases besides the preoperatively detected
lesions. Rotator cuff and labrum/SLAP repairs were
performed in the same surgical sessions. The majority
of newly detected lesions were biceps lesions, being
identified in 26 (15.5%) cases. In 41 (24.2%) cases
tenodesis, tenolysis, or tenotomy were performed
for biceps lesions. LHBT surgery was performed in
26 cases with negative MRI. Biceps lesions were
confirmed in 77 (45.8%) cases intraoperatively;
therefore, the accuracy of MRI in detecting these
lesions was 66.2%.
Conclusion
Biceps lesions are among the common pathologies
of the shoulder. Preoperative MRI is important in
evaluation of the shoulder, but the efficacy of MRI may
be limited in detecting biceps disorders. Arthroscopic
surgery is crucial in diagnosis and treatment of LHBT
lesions.
