Silva F et al. - The results of this study strongly suggest that there is no etiologic role of bursal inflammation in the trochanteric pain syndrome. Methods
Aim was to evaluate the histopathology of pts with and w/o the clinical syndrome of GT bursitis to assess for the presence of bursal inflammation
Pts who required total hip arthroplasty (THA) for rheumatoid or OA were recruited
Inclusion criteria: needing THA as standard of care; THA secondary to OA or RA; age >18; and minimal risk for surgery
Pts who received a GT bursa injection 9 mos before surgery were excluded
The harvesting of the bursa required no modification of the surgical procedure
The specimens were then examined by 2 independent pathologists who were blinded as to the patients' clinical status
Results
6 bursal specimens were evaluated by 2 blinded surgical pathologists revealing primarily fibroadipose tissue with no signs of acute or chronic inflammation
There were 3 bursas in the control group and 2 specimens with clinical GT bursitis
No significant differences were found between the specimens of the 2 groups
