Study sheds new light on joint damage in gout

New Zealand researchers have made a breakthrough in understanding how joint damage occurs in gout. 

Using plain radiographs and DECT scans in 92 patients with tophaceous gout they discovered urate crystals were were more likely to be present in joints with features of radiographic damage.

The relationship was strongest for bone erosion, spur formation and lowest for joint space narrowing and osteophyte formation, study authors Dr Nicola Dalbeth and colleagues from the University of Auckland found. 

“Direct visualisation of MSU crystals within affected joints support the concept that MSU
