We report the effective treatment of calcific tendinitis in the gluteus medius muscle with a single application of the barbotage technique. A 68-year-old man visited our hospital complaining of right hip pain with an intensity of 8 on a numeric rating scale. A simple radiograph of the right hip showed a calcific nodule at the insertion site of the gluteus medius tendon. The stage of the calcific lesion was inferred through the characteristics of the findings confirmed on radiographs. Ultrasonography was performed and the results were combined to determine the appropriate stage to apply the barbotage technique. He confirmed the pain relief effect after performing the intervention. After 1 month, it was confirmed that the calcific lesion was completely removed at follow-up.
