Comparative study on the application of tarsal tunnel block and spinal anesthesia in open osteotomy of hallux valgus

Abstract

Abstract Background Hallux valgus is a common and frequently occurring forefoot disease. Surgical treatment is often required for moderate to severe cases, and the choice of anesthesia during surgery significantly impacts postoperative functional recovery. This study aims to explore a more suitable anesthesia method for open hallux valgus surgery. Methods A total of 90 patients with hallux valgus admitted to the hospital from November 2016 to November 2020 were randomly divided into two groups: the tarsal tunnel block group and the spinal anesthesia group. Open osteotomy and internal fixation were performed on the first metatarsal and proximal phalanges using the anterolateral approach. Various observation indexes were set, and relevant data, including anesthesia operation time, anesthesia onset time, operation time, anesthesia duration, changes in vital signs during operation, fasting time, anesthesia complications, wound complications, hospitalization expenses, etc., were recorded. The VAS pain score questionnaire was filled out before and after the surgery, and a follow-up was conducted. Results The tarsal tunnel block group exhibited shorter operation and onset times of anesthesia, as well as longer duration of anesthesia effect. Moreover, fasting water was not required before or after the surgery, anesthesia complications were fewer, and patient activities were not affected. The difference between the two groups was statistically significant (P < 0.05). Conclusion The application of tarsal tunnel anesthesia instead of traditional spinal anesthesia in open hallux valgus surgery has a broader application range and can fully meet the clinical needs of open hallux valgus surgery.
