We aimed to establish the cross-sectional area (CSA) reference values for peripheral nerves of lower extremities in a healthy Chinese population, and to determine their diagnostic values for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and Charcot-Marie-Tooth disease type1A (CMT1A). One hundred eleven healthy subjects, 15-70 years of age, as well as 104 CIDP patients and 26 CMT1A patients were recruited. CSA at predetermined sites of the tibial, fibular, sciatic and sural nerves was measured. ⋯ In CIDP patients with normal upper limb ultrasound, 56% (5/9) would have lower limb nerve enlargement. All CMT1A patients had both upper and lower limb nerve enlargement. Addition of lower limb nerve ultrasound showed no added value in diagnosis of CMT1A, but could be supplementary for CIDP when upper limb ultrasound is normal.

Incomplete peripheral nerve blocks distal to the popliteal region are commonly considered a sciatic and femoral/saphenous nerve block failure. The existence of a much more distal innervation area of the posterior femoral cutaneous nerve (PFCN) as described has not been assumed yet. We therefore investigated the distal termination of the PFCN in the lower leg. ⋯ The PFCN has a much more distal termination in the lower leg than previously demonstrated. To ensure complete anaesthesia of the lower leg and foot, the PFCN must be included in combined peripheral nerve block procedures.

Observational StudyLower-limb neurologic deficit after vaginal delivery: a prospective observational study.
Among a prospective French obstetric cohort, 1 in 300 women demonstrated postpartum neuropathy, most commonly primiparous, sensory and in femoral nerve territory.
