Objective: To determine the natural history of the morphology of the median nerve after carpal tunnel decompression. Methods: Between October and December 2014, patients with suspected carpal tunnel were prospectively enrolled and underwent pre- and postoperative (3 and 6 months) high-definition ultrasonography, electrophysiology, and clinical testing. Results: A total of 81 patients were enrolled in the study; 75 (93%) could be reached for the 6-month follow-up, and 100% were clinically better at the 6-month follow-up. The mean cross-sectional area decreased from 14.3 ± 4.4 mm2 to 9.6 ± 2.3 mm2 (mean ± standard deviation [SD]). The mean distal motor latency decreased from 6.5 ± 2.2 msec to 4.4 ± 0.8 msec (mean ± SD). Distal motor latency improved statistically significantly after surgical decompression as well, but sooner. Conclusion: We present the second largest series of patients with sonographic followup after surgical decompression of the carpal tunnel. [ABSTRACT FROM AUTHOR]
