Cutaneous nerves, 1242. (1218) 

 Musculo-cutaneous nerve. 

 Anterior tibial. 

 External saphenous nerve. 

 Internal saphenous nerve. 



Dissection of Front of Leg and Dorsal Surface of Foot. 



Continue the median incision down the leg, in front of the ankle and over the dorsum of the foot to the 

 second toe. Make transverse incisions at the middle of the leg, at the ankle, and at the base of the toes, 

 also a median incision on the dorsum of each toe, to the end. Reflect the skin each way from the 

 median incisions and expose the superficial fascia, veins, and cutaneous nerves.

 Internal branch. External branch. 



Internal branch of the anterior tibial, 861. (841) 



External or short saphenous, 861. (841) 

 Turn off the superficial fascia and expose the deep fascia of the leg. 

 Deep fascia of the leg, 390. (388) 

 Anterior annular ligament, 1237(1213); also, 390-1. (388) 



Upper, above the level of the ankle-joint. 



Lower, over the. ankle-joint. 



Turn off the deep fascia, leaving the annular ligament over the ankle-joint, to retain the tendons in 

 place. As each muscle is exposed, the tendon should be traced to its terminal insertion.
