 articular margin. The anterior fibres are the thickest, strongest, and most 

 pronounced. 



The external portion (fig. 229) is attached above to the lower part of the 

 external condyle, and from this the fibres radiate to their attachment into the outer

 radius. The anterior fibres reach further forwards than the posterior do behind.
