Why do local corticosteroid injections work in carpal tunnel syndrome, But not in ulnar neuropathy at the elbow?
2016
Abstract
We read the manuscript by Podnar and Omejec1 with interest. They had commented on a study by van Veen et al. and the role of corticosteroid injections for treatment of carpal tunnel syndrome.
However, we are not at all convinced that exact targeting of the median nerve in carpal tunnel syndrome is not necessary. The authors claimed that medication delivered close to the carpal tunnel suffices.
However, Üstün et al. suggested earlier onset and better symptom relief in their ultrasound (US)-guided steroid injection group (targeting the median nerve) vs. the blind injection group.
