  Abstract: Objective To explore the clinical value of high-frequency ultrasound combined with minimally invasive plate osteosynthesis (MIPO) in preserving the supraclavicular nerve in clavicle fractures. Methods Sixty patients with mid-clavicle fractures who were treated at the First Affiliated Hospital of Ningbo University from September 2022 to May 2024 were selected. They were divided into 30 patients treated with high-frequency ultrasound combined with MIPO (minimally invasive incision group) and 30 patients treated with open reduction and locking plate fixation (traditional incision group). The perioperative indicators, VAS score, Constant-Murley score, and complication occurrence were compared between the two groups. Results All patients completed the surgery and were followed up for 6 months. The bone call formation time and incision length in the minimally invasive incision group were lower than those in the traditional incision group (P < 0.05); the Constant-Murley scores at 3 months and 6 months after surgery in the minimally invasive incision group were higher than those in the traditional incision group (P < 0.05). The incidence of skin sensory abnormalities in the minimally invasive incision group at 2 weeks,1month, and 3 months after surgery was lower than that in the traditional incision group (P < 0.05). Conclusion Compared with traditional open reduction and plate internal fixation, the high-frequency ultrasound combined with MIPO technique can effectively reduce the iatrogenic injury of the supraclavicular nerve during surgery, reduce the incidence of postoperative skin sensory abnormalities, and also have significant advantages in terms of shoulder aesthetics, shoulder joint function, and fracture healing, and is worthy of clinical application and promotion.
