Rotator cuff tear imaging in patients over 70 years: specific MRI findings?

Area of Science:

• Orthopedic Surgery
• Radiology
• Geriatric Medicine

Background:

• Rotator cuff tears are common, but specific pathological features in patients over 70 years of age remain understudied.
• Magnetic resonance imaging (MRI) is crucial for evaluating rotator cuff tears.
• This study addresses the lack of research on age-specific MRI findings in older adults with rotator cuff injuries.

Purpose of the Study:

• To describe and compare magnetic resonance imaging (MRI) findings of supraspinatus tears in patients over 70 years of age versus younger patients.
• To identify specific pathological features associated with rotator cuff tears in the elderly population.

Main Methods:

• Retrospective analysis of 50 patients with isolated supraspinatus tears, divided into two groups: <50 years (n=25) and >70 years (n=25).
• Evaluation of tear size and retraction (Patte), tendon thickness, lamellar dissection, and fatty infiltration (Goutallier), muscle size (Thomazeau), and tangent sign (Zanetti) using MRI.

Main Results:

• Contrary to hypothesis, lateral tendon thickness was similar between groups; medial tendon-muscle junction thickness was greater in younger patients.
• Older patients exhibited more pronounced lamellar dissection and severe fatty infiltration.
• Marked muscle wasting and a positive tangent sign were observed in over two-thirds of patients in the older group.

Conclusions:

• This preliminary study identified distinct MRI features of supraspinatus tears in patients over 70 years compared to younger counterparts.
• Specific findings include increased fatty infiltration and muscle wasting in older individuals.
• Larger studies are warranted to validate these age-specific MRI observations in rotator cuff tears.
