The physical functions of the heart and brain is based on the sufficiency,fluency and balance of qi and blood. Therefore,the basic pathogenesis of cardio-cerebrovascular diseases should be imbalance of qi and blood. Any causative agent is bound to influence the harmony of qi and blood once it attacks the heart and brain,its evolving laws are qi stagnancy and blood stasis at early stage,subsequent cementation of phlegm and blood stasis,and more qi deficiency and more blood stasis in the end. Regulating qi and activating blood circulation may harmonize qi and blood,balance yin and yang,which should be served as the basic therapeutic method for treating cardio-cerebrovascular diseases.

Objective:To investigate the efficacy of fixation through dual minimally invasive incisions and dual osseous channels with a loop titanium plate combined with a Dog-Bone titanium plate for acute Rockwood Ⅲ acromioclavicular dislocation in comparison with open reduction and fixation with a clavicular hook plate.Methods:A retrospective study was conducted to analyze the data of the 60 patients with acute type Ⅲ acromioclavicular dislocation who had been treated at Department of Orthopedics, Liaocheng People's Hospital from February 2019 to May 2022. There were 35 males and 25 females with an age of (43.2±8.0) years, and 34 left sides and 26 right sides affected. According to different surgical methods, they were divided into a double titanium plates group of 32 cases who had been treated by fixation through dual minimally invasive incisions and dual osseous channels with a loop titanium plate combined with a Dog Bone titanium plate and a hook plate group of 28 cases who had been treated by open reduction and internal fixation with a clavicle hook plate. The time from injury to operation was (2.1±1.3) d. The 2 groups were compared in terms of incision length, operation time, intraoperative bleeding, and visual analogue scale (VAS) pain score, Constant-Murley shoulder function score and the coracoclavicular distance on the affected side which were recorded preoperatively and at the last follow-up. Complications such as infection, loosening of internal fixation or secondary fracture were observed.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P > 0.05). All patients were followed up for (11.2±2.1) months. The incision length in the double titanium plates group [(3.5±0.3) cm] was significantly shorter than that in the hook plate group [(6.2±0.7) cm], and the intraoperative bleeding [(45.3±7.5) mL] in the former was significantly less than that in the latter [(64.1±6.2) mL] ( P < 0.05). However, there was no statistically significant difference in the operation time between the 2 groups ( P > 0.05). The VAS score [0.5 (0, 1.0) points] and Constant-Murley shoulder function score [(95.1±2.1) points] in the double titanium plates group were significantly better than those in the hook plate group [0.8 (0, 1.0) points, (86.0±4.4) points] at the last follow-up ( P < 0.05). However, there was no statistically significant difference between the 2 groups in the coracoclavicular distance on the affected side ( P > 0.05). Good acromioclavicular joint repositioning and fixation were achieved in all patients. There were no surgery-related complications except for sinus tract formation in one patient in the double titanium plates group. Conclusion:In the treatment of acute Rockwood Ⅲ acromioclavicular dislocation, fixation through dual minimally invasive incisions and dual osseous channels with a loop titanium plate combined with a Dog-Bone titanium plate is superior to open reduction and internal fixation with a clavicular hook plate, showing advantages of minimal invasion, better safety, less intraoperative bleeding, and faster joint function recovery.
