THE NERVES OF THE LOWER LIMB 



5 01 



The foot, therefore,, assumes the attitude of talipes calcaneo- 

 valgus. Loss of sensibility occurs in the skin of the sole of the 

 foot. 



The Obturator Nerve (L. 2, 3, and 4) may be injured in 

 anterior dislocations of the hip-joint, in obturator hernise, or 

 during parturition. The injury, however, is very uncommon. 



With the exception of the portion of the adductor magnus 

 supplied by the sciatic nerve (p. 410), all the adductor muscles 

 are paralysed, but no sensory disturbance is caused, as the 

 obturator nerve possesses no exclusive area of sensory supply. 



The Lateral Cutaneous Nerve of the Thigh (L. 2 

 and 3) possesses an area of exclusive supply over the proximal 

 third of the lateral aspect of the thigh. When the nerve is 

 divided, epicritic and protopathic sensibilities (p. 97) are lost 

 over this area. 



The following table shows Kocher's views with regard to 

 the segmental innervation of the muscles of the lower limb 

 (cf. p. 105).
