Abstract

Background: Carpal tunnel syndrome (CTS) is peripheral entrapment neuropathy in which compression of the median nerve at the wrist occurs. Objective: To evaluate and study, ultrasound and nerve-conduction of median nerve in predicting outcome after open surgical release in carpel tunnel syndrome. Patients and Methods: This prospective observational study, include 30 patients from out-patient Neurology and orthopedic clinics of Al Azhar Assuit University Hospitals. The duration of the study ranged from 6-12 months. Results: Ultrasound findings were significantly decreased postoperatively. As regard ROC curve of ultrasound findings in predicting outcome after open surgical release in carpel tunnel syndrome, regarding Cross-sectional area at tunnel inlet, its sensitivity was 40%, specificity was 82%, AUC was 0.615 and cutoff point was ≤ 13.5. Regarding Cross-sectional area at tunnel outlet, its sensitivity was 32%, specificity was 86%, AUC was 0.523 and cutoff point was ≤ 14. Regarding Maximal cross-sectional area along the tunnel, its sensitivity was 34%, specificity was 78%, AUC was 0.586 and cutoff point was ≤ 16. As regard ROC curve of DML; sensitivity was 87.1%, specificity was 89.7%, AUC was 0.813 and cutoff point was ≤ 4.9. Conclusion: Ultrasonography is a good sensitive tool in diagnosis of CTS as compared to the clinical examination and electrophysiological findings. Open carpal tunnel release was effective in improving CTS clinical, electrophysiological and functional parameters Most of the patients were satisfied with the results of OCTR.
