Radiographic findings associated with symptomatic rotator cuff tears

Area of Science:

• Orthopedic Surgery
• Radiology
• Sports Medicine

Background:

• Rotator cuff tears are a common cause of shoulder pain and dysfunction.
• Radiographic assessment plays a role in diagnosing and managing rotator cuff pathology.
• The relationship between specific radiographic findings and rotator cuff tears requires further elucidation.

Purpose of the Study:

• To compare radiographic features of the shoulder in patients with rotator cuff tears versus asymptomatic controls.
• To identify specific radiographic abnormalities associated with rotator cuff tears.
• To investigate potential correlations between rotator cuff tear characteristics and radiographic findings.

Main Methods:

• Retrospective analysis of shoulder radiographs from 40 patients with rotator cuff tears and 84 asymptomatic controls.
• Standard radiographic views obtained: acromioclavicular joint, anterior-posterior with external rotation, and supraspinatus outlet.
• Blinded interpretation of 14 radiographic areas by two fellowship-trained radiologists.

Main Results:

• Greater tuberosity abnormalities (sclerosis, osteophytes, subchondral cysts, osteolysis) were significantly more prevalent in the rotator cuff tear group.
• No association was found between acromial morphology and rotator cuff tears.
• No correlation between rotator cuff tear length and observed degenerative radiographic conditions.

Conclusions:

• Shoulder radiographs can reveal specific greater tuberosity abnormalities in individuals with rotator cuff tears.
• These radiographic findings are distinct from those in asymptomatic individuals.
• Radiographic assessment of the greater tuberosity may aid in the diagnosis of rotator cuff tears, independent of tear size.
