Nice, we'd use this in coding the Lumbosacral plexus mnemonics. During the procedure, a donor nerve (e.g., sural nerve, genitofemoral nerve) is harvested from the patient and joined to the distal and proximal ends of the resected cavernous nerve. The lumbar plexus receives input from L1 (variable input from T12) to L4 and produces the femoral nerve, lateral cutaneous nerve of the thigh, obturator nerve, as well as the iliohypogastric, ilioinguinal and genitofemoral nerves. CONCLUSION: Postsling neuralgia diagnosis using sen-sory mapping and a nerve stimulator aids in indentifying the nerve involved and in successful conservative treat-ment with a nerve block. Lateral femoral nerve. The ilioinguinal nerves and the genitofemoral nerves arise from the spinal cord and supply the skin and structures around the groin area, including the genitals. Patients who received a nerve graft taken from the thigh (a genitofemoral nerve graft) instead of the ankle were as likely to recover erectile function as those who received a sural nerve graft. A great many nerves exist in this area, however, and the ilioinguinal nerve is not a primary player; arousal and sexual function, for instance, are part of a separate system. HYPOTHESIS We hypothesized that the transfer of a somatic nerve (genitofemoral, GF, a nerve of L3,L4 origin in dogs) to the anterior vesical branch of the pelvic nerve (PN, nerves of upper sacral origin) of a neurogenic bladder (due to spinal root injury), would restore bladder function by the ingrowth of new axons from the transferred GF nerve . The genitofemoral nerve is responsible for both the sensory (femoral branch) and motor portions (genital branch) of the cremasteric reflex, which describes contraction of the cremasteric muscle when the skin of the superior medial part of the thigh is touched. The groin is supplied by a group of nerves that control sensation and certain muscle functions. Sensory functions of posterior femoral cutaneous. The nerve descends in the retroperitoneum to give off genital and femoral terminal branches supplying the skin over the anterior scrotum or labia majora and lateral femoral triangle respectively. Central and peripheral motor conduction to cremasteric muscle. The genitofemoral nerve was chosen as the ideal candidate for nerve transfer due to its proximity, as well as mixed-autonomic nerve function which includes the synergistic function of the cremasteric reflex.
