INTROUCTION Rotator cuff tears are a common pathology with a varied prevalence reported. PPATIENTS AND METHODS: A literature review was undertaken to determine the cadaceric radiological ultrasonography and magnetic resonance imaging (MRI) prevalence of rotatator cuff tears. The radiological studies were subdivided into symptomatic and asymptomatic subjects. RESULTS Cadaverte rotator cuff tears were found in 4629 shoulders of which only 2553 met the inclusion criteria. The prevalence of full thickness tears was 11.75% and partial thickness 18.49% (total tears 30.24%). The total tear rate in ultrasound asymptomatic was 38.9% and ultrasound symptomatic 41.4%. The total rate in MRI asymptomatic was 26.2% whilst MRI symptomatic was 49.4%. DISCUSSION The unselected cadeveric population should contain both symptomatic and asymptomatic subjects. A prevalence of tears between the symptomatic and asymptomatic radiological groups would be expected. However, aprt from the MRI asymptomatic group, the radiological prevalence of rotar cuff tears exceeds the cadaveric. CONCLUSION Rotar cuff tears are frequently asymptomatic. Tears demonstrated during radiological investigation of the shoulder may be asymptomatic. It is important to correlate radiological and clinical findings in the shoulder.
