“…This membrane appears as a hyperechoic band joining the tibia and the fibula and separating the tibialis anterior from the tibialis posterior. 7 During the posterior approach, the needle should be passed through the soleus and the flexor digitorum longus after penetrating the skin just beneath the tibia from the medial side.…”

“…The posterior neurovascular bundle consists of the posterior tibial artery and veins and the tibial nerve. 7 The safety window width was defined as the distance between the innermost margin of the tibia and neurovascular bundles, and safety window depth was defined as the distance between the skin and the tibialis posterior muscle (Fig. 2B).…”

“…The mean (SD) safety window width (tibia to the neurovascular bundle) in healthy adult subjects as determined by magnetic resonance imaging has been reported to be 12.34 (3.59) mm for the anterior approach and 6.76 (4.67) for the posterior approach. 7 It was found out that the size of safety window in children was approximately a half to two-thirds of adult sizes through their preliminary observation. On the basis of these previous results, it was assumed that window sizes in children would be approximately a half to two-thirds of adult sizes, with a mean difference of 10 mm and an SD of 1.5 mm.…”

“…3,4 The grayscale sonographic pattern has been described as a uniformly hypoechoic pattern proximal to the site of injury, and disturbance in the microvasculature has been noted. 5 This increase in vascularity represents a pathogenic repair process of the nerve and can be appreciated with color and power Doppler imaging. 5 …”

Objectives The purpose of this study was to provide clinical evidence of the use of contrast-enhanced sonography in detecting and quantifying changes in intraneural vascularity due to median mononeuropathy. Methods Five Macaca fascicularis monkeys were exposed to 20 weeks of repetitive work to increase their risk of developing median mononeuropathy. Contrast-enhanced sonograms were obtained in 30-second increments for 7 minutes while a contrast agent was being delivered. Data were collected immediately at the conclusion of the 20-week work exposure and then again during a recovery phase approximately 3 months after the completion of work. Quantitative analysis and trend graphs were used to analyze median nerve perfusion intensity. This study also compared the use of both manual counting of pixels and semiautomatic measurement using specialized software. Results Based on the average data, maximum intensity values were identified as the best indicators of nerve hyperemia. Paired t tests demonstrated significantly higher maximum intensities in the working stage for 4 of the 5 subjects (P < .01). Conclusions This study provides preliminary evidence that (1) in a controlled exposure model, a change in intraneural vascularity of the median nerve between working and recovery can be observed; (2) this vascular change can be measured using an objective technique that quantifies the intensity of vascularity; and (3) contrast-enhanced sonography may improve the ability to reliably capture and measure low-flow microvascularity.
