Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
We hypothesize that the cross sectional area of the PTN will correlate with motor conduction velocity on nerve conduction studies (NCS) following PTN block in patients with peripheral neuropathy. All eligible patients will undergo NCS to confirm or exclude distal neuropathy. Patients without neuropathy will be excluded from further participation in this study. Also excluded will be diabetic patients with neuropathy caused by genetic, metabolic and inflammatory diseases as well as toxic agents and drug induced. A systematic US examination of the PTN will be performed for all patients. After Block administration at surgery day the block successes will be assessed and for the purposes of the present study, patients in whom the block was not successful will be excluded from further intervention and data analyses. Eight weeks after surgery, all study patients will return to hospital for repeat NCS and US.
