Ahead of Print: Diagnostic Accuracy of EMG and Imaging Studies

Background: Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome. It is sometimes difficult to diagnose, and a late diagnosis may result in permanent nerve damage. Electromyography (EMG), ultrasonography (US), magnetic resonance imaging (MRI), and computed tomography (CT) may be performed for the diagnosis. The diagnostic accuracy of these tests is well documented, but most of these studies accept EMG as the gold standard.

Objective: To evaluate the diagnostic accuracy of EMG, MRI, CT, and US for the diagnosis of carpal tunnel syndrome using clinical findings as the gold standard.

Methods: Patients suspected to have CTS on presentation to the outpatient clinic were evaluated. The tests were performed after a detailed physical examination. Both wrists of the 69 patients in the study were investigated.

Full article access for Neurosurgery subscribers at

BACKGROUND: Partial contralateral C7 transfer has been widely used, but outcomes are significantly different. Therefore, the effects of this procedure need to be evaluated.

OBJECTIVE: To evaluate the outcome of patients treated with partial contralateral C7 transfer and to determine the factors affecting the outcome of this procedure.

METHODS: A retrospective review of 46 patients with global root avulsion brachial plexus injuries who underwent contralateral C7 transfer was conducted. All surgeries were performed by two stages and median nerve was the recipient nerve. The contralateral C7 nerve was used in three different ways. The whole C7 root was used in 8 patients; the posterior division together with the lateral part of the anterior division was used in 14 patients; and the anterior or the posterior division alone was used in 24 patients. The mean follow-up period was 6.4 years.
