Abstract Background Carpal tunnel syndrome (CTS) is the most common nerve entrapment syndrome. It is caused by compression of the median nerve as it passes through the carpal tunnel in the wrist. The diagnosis of CTS is based on a combination of characteristic symptoms and electrophysiologic abnormalities. Electrodiagnostic testing (EDT) is uncomfortable for patients, time consuming and expensive. Objective To evaluate the role of greyscale and strain elastography ultrasound imaging in diagnosing patients with CTS and controls in comparison with nerve conductive studies. Patients and Methods Type of Study: Descriptive, prospective study. Study Setting: The study will be conducted at Ain Shams University Hospitals, Radiodiagnosis department. Study Period: 6 months. Study Population: Patients with carpal tunnel syndrome diagnosed clinically and underwent nerve conduction velocity study. Results In this study 7 wrists were diagnosed with mild CTS, 5 wrists demonstrated moderate CT, whereas only 3 wrists revealed severe CTS. The mean CSA would have increased if the number of cases with severe CTS had been higher. CSA of the median nerve has been reported to increase with the severity of entrapment. The cut off point of the average CSA to differentiate between cases and controls was found > 8 with sensitivity of 93.33%, specificity of 80% and area under curve (AUC) of 91.3% while the best cut off point for Elasto score was found > 1 with sensitivity of 86.6%, specificity of 80% and area under curve (AUC) of 93.3%. Conclusion We concluded that sonoelastography is a sensitive tool for prediction of CTS and it’s severity in correlation to NCV.

Results Of Surgery

Fifty-three hands with carpal tunnel syndrome had pre- and postoperative evaluations of median nerve distal motor latency (from wrist to thenar muscles) and orthodromic sensory nerve conduction velocity (from thumb and middle finger to wrist). At 6 months we observed a neurophysiological return to normal in all cases with normal preoperative distal motor latency and in about 50% of the hands with preoperative distal motor latency between 4 and 6 ms. Prolongation of the distal motor latency over 6 ms was not followed by return to neurophysiological normality, although some degree of sensory function was restored in the majority of cases.

Upper Extremity Symptoms

Electrodiagnostic testing in patients who have upper-extremity symptoms, which may include carpal tunnel syndrome (CTS), has been the gold standard for diagnosis for many years. Depite their value, these tests are underutilized. The authors examined the use patterns of electrodiagnostic testing at the University of Virginia by reviewing the records of the Electromyography Laboratory for the calendar year 1994. Studies in patients with CTS comprised 15% of the 1626 studies performed during that time. The mononeuropathy was mild in the majority of cases and most of the patients were referred for testing by specialists. There was a clear referral bias on the part of the primary care physicians, and the severity of mononeuropathy in the patients they referred for testing was significantly greater than in patients referred by specialists. The data indicate that electrodiagnostic testing has clear value in the evaluation of patients who have upper-extremity symptoms. Despite this fact, primary care physicians appear to underutilize electrodiagnostic testing.

Objective To describe a new mini-invasive surgical technique for carpal tunnel release and to present clinical findings associated with using this technique. Methods Patients with idiopathic carpal tunnel syndrome without prior surgical treatment, who underwent a new minimally-invasive surgical technique using a specific surgical tool-kit developed by the author, were included. Prospective data were collected, including preoperative electrodiagnostic testing. The subjective condition of all patients was evaluated pre- and postoperatively with a five-level Likert-type scale (LS) and muscular strength was tested using a JAMAR dynamometer and pinch gauge. Results A total of 116 patients (157 hands/cases) underwent surgery performed by the author, and were followed for a mean of 40 months (range, 6 months–7 years). Of these, preoperative electrodiagnostic testing was performed in 112 patients (96.6%). No significant complications were reported. By three months, patients reported that they were satisfied or very satisfied in 147/149 cases (98.7%; LS grade I and II). Strength recovery at three months, based on the average of four measures, was 99.17% (range, 97.43–100.97%). Conclusions The described technique is minimally invasive, safe and simple to perform, and provides good results.
