SURGICAL APPLIED ANATOMY. [Chap. xiv. 



the supinator longus (cut the whole length of the flap), 

 then the flexor sublimis (cut to a like extent), and, 



lastly, the flexor carpi ul- 

 iiaris. Between the supi- 

 nator longus and the flexor 

 sublimis the divided end of 

 the pronator teres is seen ; 

 and between the flexor sub- 

 limis and the. skin would 

 ^ lie the flexor carpi radiulis 

 and the palmaris longus. 

 The latter would appear as 

 Section a tendon at the inner 

 border of the flap. In the

it, would be the lowest part 



of the small supinator, while behind the ulna would 

 be the cut fibres of the upper end of the extensor 

 ossis. On the face of the posterior flap would be 

 seen from without inwards the extensor carpi radialis 

 longior and brevior, the extensor communis, the ex- 

 tensor of the little finger, and the extensor carpi 

 ulnaris. The radial artery will run the whole length 

 of the anterior flap, and be cut near its outer border 

 to the inner side of the supinator longus. The ulnar 

 artery will be cut shorter, will be in front of the bone, 

 and between the flexor sublimis and flexor profundus. 

 The anterior iiiterosseous vessels will be divided in- 

 vnediately in front of the iiiterosseous membrane.
