| Abstract |
|
The diagnosis of ulnar nerve compressive neuropathy has traditionally relied on the informations obtained from clinical symptoms, physical examination, and electrodiagnostic studies. Although most of the compressive neuropathy can be confirmed without further study, sometimes undetected space occupying lesions (SOL) are found during the operation. Recently, the usefulness of ultrasonography in the diagnosis of compressive peripheral neuropathy has been emphasized and its advantage in the diagnosis of carpal tunnel syndrome has been widely investigated. We performed the ultrasonographic exmination combined with the electrodiagnostic studies for the evaluation of ulnar nerve compressive neuropathy. Ninety patients were diagnosed with ulnar nerve compressive neuropathy between September 2004 and October 2006. Thirty-two patients were operated and the preoperative ultrasonography detected 8 cases of SOLs as a cause of ulnar nerve compressive neuropathy. Our study shows ultrasonography is very useful tool that can localize the lesion, detect the SOL and morphologic changes of compressed ulnar nerve. Its cost effectiveness, time to perform, detailed information to the neurovascular structures, and unique real-time capabilities that permit examination of tissues in both static and dynamic states suggest ultrasnography could become a routine diagnostic modality for the patients with ulnar nerve compressive neuropathy. |
