Abstract
The objective of this study was to retrospectively evaluate the prevalence of the cystic changes at rotator cuff footprint on proximal humeral tuberosities and investigate their relationship with rotator cuff tears and patient age Magnetic resonance MR images of 657 patients who underwent shoulder arthroscopy for treatment of rotator cuff disorders were reviewed to localize the cystic changes at anterior supraspinatus insertion and posterior infraspinatus insertion aspects of greater tuberosity GT and lesser tuberosity subscapularis insertion Preoperative MR reports as well as cyst size and locations on MR images were correlated with arthroscopic records of rotator cuff pathology tear type size location and tendon involvement and patient age The prevalence of cystic changes was 91 60 patients in the study population Anterior GT cysts were found in 56 of patients and were strongly associated with fullthickness p 001 and articularsided partialthickness rotator cuff tears p = 02 Posterior GT and lesser tuberosity cysts were found in 27 and 17 of patients respectively and were not significantly related to rotator cuff tears although there was an increased trend of posterior cysts in patients with infraspinatus tears p = 09 A significant relation was found between patient age and the cyst size p = 01 while none of the cyst localizations were statistically related to age Anterior GT cysts were more common in this patient group and demonstrated a strong association with rotator cuff disorders regardless of age Posterior GT and lesser tuberosity cysts were less common and showed no association with rotator cuff pathology or patient ageWe hereby state that all ethical legal and patient rights wise considerations were fulfilled during and after this report We report no possible conflicts of interest with any institutions or companies and also no outside funding or grants None of the researchers or an affiliated institute received from a commercial entity something of value related in any way to this report The investigation was performed at Gazi University Hospital Ankara Turkey
