“…This is the fourth case in the literature to report an AVN of the triquetrum. 1,4,5 The rarity of AVN in the triquetrum in comparison to other carpal bones is explained by the classification of Gelberman et al This classifies risk patterns of AVN by dividing the carpal bones into three groups based on size and location of nutrient vessels, the presence or absence of intraosseous anastomoses, and the dependence of large areas of the bone on a single intraosseous vessel. Group III bones such as the triquetrum have rich extra-and intraosseous vascularity, resulting in a lower risk of AVN.…”

The triquetrum is rarely affected by avascular necrosis compared with other carpal bones. We report a case of avascular necrosis of the triquetrum in a 50-year-old patient, with a history of wrist trauma, local corticosteroid injections, and heavy smoking. She presented with severe wrist pain and signs of cystic changes and avascular necrosis determined by magnetic resonance imaging. She was effectively treated with a proximal row carpectomy. We suspect that the combination of the injury in combination with local corticosteroids and smoking may have led to the necrosis.
