Diagnosis of carpal tunnel syndrome
Wythenshawe Hospital, Southmoor Road, Manchester M23 9LT, UK
SIR, I read with interest the paper by O'Gradaigh and Merry on the use of Bayes's theorem to produce a diagnostic algorithm for carpal tunnel syndrome [1]. Bayes's theorem may have a useful place in clinical practice, as also indicated by our own previous study [2] with regard to isotope scanning of sacroiliac joints in suspected inflammatory spondylitis as well as with HLA-B27 typing of these patients.
As pointed out by the authors, our own recent study did reveal long waiting times for the simple nerve conduction tests that are so useful in evaluating patients with paraesthesia, including suspected carpal tunnel syndrome [3]. I would, however, like to voice some concerns on diagnosing the majority of patients using the suggested algorithm and without the use of nerve conduction tests, as advocated by the authors for a number
