Is severity of scapholunate instability related to joint anatomy and congruency?
This study suggests that the bony anatomy of the radius and scaphoid have a role in stabilizing the carpus after ligament injury. The effect of ligament sectioning on producing carpal instability may be moderated by the bone geometry of the radiocarpal joint. This may explain why some people may have a tear of the scapholunate interosseous ligament but not present with clinical symptoms.
This study demonstrated that osmotic fragility of erythrocyte was greater in type 2 diabetic subjects compared to non-diabetic controls and red blood cell fragility was positively correlated with glycosylated hemoglobin. Hence, it is necessary to emphasize increasing investigations of pathogenic mechanisms exacerbated by red cell fragility to prevent complications of diabetes mellitus.
