Digital economy, centered around information technology, encompasses digital content, digital industries, digital commerce, and represents a new global economic form. Its application can bring about new development opportunities and enhance efficiency. Rural revitalization is an important recent national strategy aimed at strengthening economic, social, and ecological aspects of rural development, promoting sustainable urban-rural integration. This involves the development of agriculture, rural infrastructure, the creation of beautiful rural landscapes, and ensuring the livelihood of rural residents. The digital economy plays a crucial role in rural revitalization, relying on information technology and employing digitalization, networking, and intelligence to drive industrial transformation, enhance efficiency, and promote innovation, thus forming a new economic model. Specifically in rural areas, the digital economy builds rural e-commerce platforms, offering new sales channels for farmers, creating smart agricultural ecosystems, establishing environmentally friendly foundations for sustainable agriculture, and upgrading rural financial services through digitization, optimizing the allocation of rural financial resources. This accelerates the digitization of rural tourism development and spurs the growth of surrounding rural service industries. Therefore, the digital economy holds significant practical importance for rural revitalization.

Aim: To retrospectively analyze and compare ultrasound-assisted localization in situ with the traditional, open incision method for treating cubital tunnel syndrome (CuTS)., Material and Methods: We retrospectively analyzed 51 patients treated between 2018 and 2022 and categorized them according to treatment method: ultrasound-assisted precise localization in situ decompression (n=21; Cohort 1) and traditional open incision in situ decompression (n=30; Cohort 2). We additionally collected Visual Analogue Scale (VAS) scores, Vancouver Scar Scale (VSS) scores, modified Bishop scores, aesthetic appearance, preoperative Dellon's stage, and analgesics requirements. Additional dependent variables of interest included operation time, hospital stay duration, complications, and reoperation rate., Results: Neither cohort demonstrated significant changes in Dellon's stage, modified Bishop score, or VAS scores between baseline and 6 weeks postoperative. Cohort 1 showed better aesthetics and postoperative VSS and VAS scores than Cohort 1. In addition, Cohort 1 enjoyed a significantly shorter mean operation time and hospital stay. Cohort 1 had 5 (23.80%) complications, including superficial infection (n=1), hematoma (n=1), and incomplete decompression (n=3). Cohort 2 had 9 complications (30.00%), including superficial infection (n=2), hematoma (n=2), and severe scarring (n=5). The partial, incomplete decompression cases in Cohort 1 and the severe scar case in Cohort 2 were treated with reoperation., Conclusion: Both procedures effectively treated most cases of CuTS and were associated with good postoperative outcomes. Patients who underwent ultrasound-assisted localization in situ decompression had shorter surgeries and hospital stays, better postoperative aesthetics, better VSS and VAS scores, and required less pain medication during the postoperative period. Traditional open incision in situ produced a more thorough decompression.
