Neurophysiological evaluation provided diagnosis of CTS 43%of women in one hand at least. • Acta Neurochir (Wien). 2006 Diagnostic properties of nerve conduction tests in population-based carpal tunnel syndrome Using the clinical diagnosis of CTS as the criterion standard, nerve conduction tests had moderate sensitivity and specificity and a low positive predictive value in population-based CTS. Measurement of median-ulnar sensory latency difference had the highest diagnostic accuracy BMC Musculoskeletal Disorders 2003 • The overall prevalence of radial nerve palsy after fracture of the shaft of the humerus in 21 papers was 11.8% (532 palsies in 4517 fractures). • Studies published in the past 40 years of 391 papers identified initially, 35 papers met all our criteria for eligibility. Shao YC et al J Bone Joint Surg Br. 2005 Iatrogenic nerve palsy • A total of 707 humerus shaft fractures were treated operatively at our two hospitals over a 10-year period. Of these, 30 patients sustained iatrogenic radial nerve palsy. • Wang J et al.
