Calcific tendinopathy is common in females of age group 40–60 years causing severe pain and disability in shoulder movements causing a clinical picture of a frozen shoulder. Rarely the onset of pain may be subacute and chronic.
It is believed to be a degenerative process with the deposition of calcium hydroxyapatite crystals following the metaplastic transformation of tenocytes to chondrocytes in the tendons of the rotator cuff. Three stages have been described.
A 55-year-old female with a history of regular intake of calcium supplements came with complaints of excruciating pain and restricted mobility of the left shoulder joint. The patient was managed conservatively and regained the full range of movement. Other treatment modalities may be required in a subset of nonresponsive patients.
