High-resolution ultrasound (HRUS) may offer a viable and cost-effective imaging option for assessing the morphology of nerve injuries. Consequently, a systematic review and meta-analysis of studies on the use of ultrasound for diagnosing traumatic nerve injuries were conducted. A total of 15 studies were included, reporting the most recent findings on using HRUS in the diagnosis of traumatic nerve injury. These studies assessed the diagnostic test accuracy of ultrasound for the detection of traumatic nerve injury in 272 participants, with the cross-sectional area at the site of traumatic nerve injury also reported in 1,249 participants. The pooled sensitivity and specificity of the included studies were 92% confidence interval (CI) (0.89-0.95) and 86% CI (0.82-0.89), respectively. The positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 13.76 CI (1.41-134.34), 0.08 CI (0.03-0.18), and 286.23 CI (21.22-3,860.40), respectively. In the summary of the receiver operating characteristic curve, the area under the curve was 0.986, and the Q* index was 0.949.
