Any pathologic process in the lumbar spine compressing a nerve root can cause localized pain in the back accompanied by sciatica. Most of these conditions can be differentiated by means of an MRI scan. The MRI image of a localized plexus of epidural veins, however, closely resembles that of a prolapsed intervertebral disc, which may be diagnostically misleading.
37 patients who had been operated upon for trigger thumb, all below 15 years of age, have been reviewed. 75% of the affected thumbs were on the dominant hand and 25% have bow-stringing of 1-2 mm. without any complaints. All had good results. Unlike other authors, we found that operation done after the third year of age gave full correction of the flexion contracture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
