Primary involvement of carpal bones in septic arthritis is a rare event. We report here a case of idiopathic septic arthritis with isolated involvement of the scaphoid-trapezium joint. An elderly patient presented with collapse and symptoms of septicaemia, and right wrist that was swollen and tender. Radiographs revealed erosion of the scaphoid-trapezium joint and increased joint space. The joint was aspirated yielding frank pus. Swelling and redness improved, but the patient died due to ongoing septicaemia. Localised septic arthritis of the scaphoid-trapezium joint, however rare, can be fatal if not aggressively treated in a timely fashion.

Introduction: Fluorosis has been associated with an increased risk of degenerative changes in the knee. Multiple studies have found an association between arthritis and elevated fluoride levels. We aim to delineate if elevated fluoride level has any direct correlation with the degree of radiological grading and clinical symptoms in knee arthritis. Materials and Methods: A cross-sectional study of 80 knee arthritis patients was conducted from February 2017 to April 2018. Serum fluoride levels were measured and patient’s pain scores, WOMAC scores and radiological grading were correlated with the elevated fluoride levels. Results: In our study, 30 out of 80 patients had increased serum fluoride level. Statistically significant differences were noted in VAS score, WOMAC score and Kellgren and Lawrence radiological grades between patients with normal serum fluoride level and those with elevated fluoride level. Conclusion: There is an increased risk of knee arthritis in patients with elevated blood fluoride levels and patients with increased fluoride levels are associated with more severe symptoms and radiographic disease.
