  • Crystal arthropathy
    Crystal arthropathy
    Crystal arthropathy refers to a type of arthropathy characterized by accumulation of crystals in joints. Polarizing microscopy and application of other crystallographic techniques have improved identification of different microcrystals including monosodium urate, calcium-pyrophosphate dihydrate,...
