Abstract
Nowadays it is well known that both a clinical examination and an imaging investigation (MRI/CT scans) are useful in order to provide surgeons with complete informations about the proposed treatment for shoulder pain. The purpose of this study was to evaluate the diagnostic sensitivity of the Neer, Hawkins, Jobe, Lift-off and Infraspinatus tests in diagnosing rotator cuff tears and compare this with what was found during surgery.
From 2001 to 2003, data from 430 patients who underwent shoulder open surgery, performed by a single surgeon, were documented. The results showed that the Jobe test has a sensitivity of 97.5% and positive prognostic value (PPV) of 80.3% and negative prognostic value (NPV) of 90.9% for the presence of a supraspinatus lesion; the Neer, Hawkins and Yokum tests have a sensitivity close to 95% for assessing subacromial bursitis; the Lift-off and Infraspinatus tests have a sensitivity close to 70% for assessing the degree of lesion and identify a severe lesion with a NPV over 83%. The Lift-off and Infraspinatus tests also provide information concerning muscular trophism and concerning retraction and degeneration of tendons.
According to our results, clinical evaluation of shoulder pain should be supported by imaging investigations for diagnosis of rotator cuff tear.
