Abstract:
Objective:To investigate the effect of intraoperative protection of the supraclavicular nerve on the healing of clavicular 1/3 mid-shaft fracture.Methods:A retrospective study was conducted to analyze the 83 patients who had been treated for clavicular 1/3 mid-shaft fractures at Department of Orthopaedics, The First Central Hospital of Baoding from June 2021 to March 2022. There were 57 males and 26 females with an age of (48.1±12.8) years. The patients were divided into 2 groups according to whether the supraclavicular nerve was protected or not during operation. There were 39 cases in the observation group (the supraclavicular nerve was protected during operation) and 44 cases in the control group (the supraclavicular nerve was not protected during operation). The incision length, operation time, intraoperative blood loss, hospital stay, visual analogue scale (VAS) pain scores before operation and 3, 6 and 12 months after operation, fracture healing at 3, 6 and 12 months after operation, and postoperative complications were recorded and compared between the 2 groups. Additionally, the number of microvessels in the middle clavicle was recorded and compared between the affected and healthy sides in 8 patients in the observation group at 6 weeks after operation.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The operation time for the observation group [(72.2±5.4) min] was significantly longer than that for the control group [(61.1±4.7) min]. The VAS scores at postoperative 3 and 6 months for the observation group [2.7 (2.4, 3.1) and 2.1 (1.9, 2.6) points] were significantly lower than those for the control group [3.5 (3.2, 3.8) and 2.7 (2.4, 2.9) points] ( P<0.05). The fracture healing rates at postoperative 3 and 6 months in the observation group [97.4% (38/39) and 100% (39/39)] were significantly higher than those in the control group [81.8% (36/44) and 86.4% (38/44)] ( P<0.05), but there was no significant difference in the fracture healing between the 2 groups at 12 months after operation ( P>0.05). At 6 weeks after operation, the number of microvessels in the middle clavicle was respectively 85.3±0.7 and 87.1±0.8 in the 8 patients in the observation group, showing no significant difference ( P>0.05). After operation, delayed incision healing occurred in 3 cases in the observation group and in 4 cases in the control group, and abnormal sensation of the skin around the incision occurred in 9 cases in the observation group and in 26 cases in the control group, showing a significant difference between the 2 groups ( P<0.05). Conclusion:Intraoperative protection of the supra-clavicular nerve is beneficial for reduction of early postoperative pain and improvement of early fracture healing, and may have a positive effect on the postoperative reconstruction of microvascular network.
