Bilateral gluteus medius and minimus calcific tendonitis in a patient with previous bilateral calcific tendonitis of the shoulder: A case report

Calcific tendinitis of gluteus maximus insertion

“…Calcific tendinitis, classified as enthesopathy, is a self-limiting disease characterized by the deposition of calcium phosphate crystals in tendons, causing inflammation and pain. The most commonly affected site is the supraspinatus tendon of the shoulder [ 4 ], with rare cases involving the tendons of the gluteus medius and gluteus maximus reported in medical literature [ [3] , [4] , [5] , [6] , [7] , [8] ]. The condition can present as acute or chronic hip pain and predominantly occurs in people over the age of 40 and is rare in those older than the age of 70 [ 3 , 9 ].…”

“…Calcium hydroxyapatite crystal deposition can occur in various parts of the body. While it rarely occurs in the hip, the gluteus medius is one of the more commonly involved tendons [ 2 , 3 ] in such cases. Calcific tendinitis of the gluteus medius can present as either acute or chronic [ 7 , 11 ].…”

“…Calcific tendinitis is caused by the accumulation of calcium hydroxyapatite crystals [ 1 ] in peri-articular musculature attachment sites. It most often occurs in people aged 40 to 70 years [ 1 , 2 ]. Risk factors include an inciting trauma, which could be repetitive, as well as metabolic and autoimmune disorders, such as rheumatoid arthritis [ 1 ].…”
