Objective To summarize the method and effectiveness of open reduction and internal fixation in the treatment of 4 cases of bipolar clavicle dislocations. Methods Between June 2017 and June 2022, 4 patients with bipolar clavicle dislocations were admitted. There were 3 males and 1 female. The age ranged from 27 to 63 years, with an average age of 45 years. There were 2 cases of crushing injury of mine car, 1 case of traffic accident injury, and 1 case of heavy object injury. The time from injury to operation was 3-7 days, with an average of 5.0 days. The sternoclavicular joint dislocations were classified as Grade Ⅱ in 1 case and type Ⅲ in 3 cases, and anterior dislocation in 3 cases and posterior dislocation in 1 case. The acromioclavicular joint dislocations were classified as Tossy type Ⅱ in 2 cases and type Ⅲ in 2 cases. After open reduction, the sternoclavicular joint and acromioclavicular joint were fixed with lateral malleolus locking titanium plate and clavicular hook plate, respectively. ResultsAll operations were successfully completed without vascular or nerve injury. All incisions healed by first intention. All patients were followed up 12-18 months, with an average of 14 months. At last follow-up, the shoulder joint functions were rated as excellent in 3 cases and good in 1 case according to Rockwood score. During follow-up, there was no loosening of internal fixator or fracture. The internal fixators were removed in all patients at 5-7 months after operation (mean, 6 months), and no re-dislocation occurred after removal. Conclusion For bipolar clavicle dislocation, open reduction combined with lateral malleolus locking titanium plate fixation of the sternoclavicular joint and clavicle hook plate fixation of the acromioclavicular joint can achieve good effectiveness. It has the advantages of simple operation, high safety, firm fixation, and fewer complications, and the shoulder function recovers well.
Objective To compare the cl inical results of two plating osteosynthesis techniques, open reduction and plating ostosynthesis (ORPO) and minimal invasive plating osteosynthesis (MIPO), in surgical treatment of mid-distal humeralshaft fractures. Methods From March 2004 to October 2006, 40 cases of closed unilateral mid-distal humeral shaft fractures were surgically treated with MIPO or ORPO. In the MIPO treated group (n=19), there were 14 males and 5 females, with a mean age of 39.05 years. Fractures involved in middle humeral shaft in 10 cases and distal fragment in 9 cases. According to OTA classification, there were 3 cases of type A, 13 cases of type B and 3 cases of type C. Four cases compl icated by radial nerve palsies. In the ORPO treated group (n=21), there were 13 males and 8 females with a mean age of 39.05 years, including 14 cases of type A and 7 cases of type B fractures according to OTA classification. The fractures involved in middle humeral shaft in 13 cases and distal fragment in 8 cases. Five cases compl icated by radial nerve palsies. The time from injury to operation in both groups were 2 to 14 days. For patients in the MIPO group, fractures were closely reduced and fixated with an anterior placed plate inserted through two small incisions made at the anterior side of arm, away from fracture sites. The radial nerves were not exposed. For patients in the ORPO group, fractures were exposed, reduced, and fixated with an anterolateral or a posterior positioned plate after careful dissection and protection of radial nerve through an anterolateral or a posterior approach. The operation time, the occurrence of iatrogenic radial nerve palsy and the bone heal ing time were recorded. The functions of the affected shouldersand elbows were evaluated with UCLA end-result score and Mayo elbow perform index (MEPI), respectively. Results All the wounds in both groups healed primarily. There was no iatrogenic radial nerve palsies in the MIPO group after surgery; however, 5 cases of transient iatrogenic radial nerve palsies were identified in the ORPO group after surgery, and the function of radial nerve recovered in these cases at the last follow-up. Eighteen cases were followed up 14-44 months (mean 25.44 months) in MIPO group, and 19 cases were followed up 13-48 months (mean 32.11 months) in ORPO group. The mean bone heal ing time was 17.06 (12-32) weeks in MIPO group and 16.11 (8-58) weeks in ORPO group, showing no significant difference between two groups (P gt; 0.05). There was no nonunion and hardware failure in both groups. The mean forward flexion of the shoulder was 166.94° (150-170°) in MIPO group and 164.74° (130-170°) in ORPO group. The mean UCLA shoulder score was 34.78 (33-35) points in MIPO group and 34.42 (30-35) points in ORPO group. The mean range of motion of the elbow in MIPO and ORPO groups was 133.33° (120-140°) and 136.7° (120-140°), respectively. The MEPI in these two groups was 99.44 (90-100) and 99.74 (95-100) points, respectively. There was no statistically significant difference between two groups in all indexes mentioned above. Conclusion The good results could be obtained when ORPO and MIPO technique are appl ied to treat mid-distal humeral shaft fractures. MIPO technique has advantages to not expose the radial nerve and to decrease the occurrence of iatrogenic radial nerve palsies.
Objective To investigate therapeutic effect of endoscopic sphincterotomy with small incision (SES) combined with endoscopic papillary balloon dilation (EPBD) in treatment of larger common bile duct stones. Methods The clinical data of 80 patients with common bile duct stones treated in our hospital from February 2014 to October 2015 were retrospectively analyzed. These patients were divided into endoscopic sphincterotomy (EST) group (n = 40) and SES+EPBD group (n = 40) according to the therapeutic methods. The diameter of common bile duct stone was 10–20 mm. The operation status, recurrence rate and residual rate of common bile duct stone, and complications rate within 3 months after operation were compared between these two groups. Results The age and gender had no significant differences between these two groups (P>0.05). The operation time was shorter (P<0.05) and the intraoperative bleeding was less (P<0.05) in the SES+EPBD group as compared with the EST group. There were no significant differences in the hospital stay and recovery time of gastrointestinal function between these two groups (P>0.05). The levels of ALT, AST, DBIL, and TBIL in these two groups before treatment had no significant differences (P>0.05); after treatment, the above indicators of liver function in the SES+EPBD group were significantly lower than those in the EST group (P<0.05), and which were significantly decreased more in the same group (P<0.05). The residual stone, stone recurrence, and complications such as acute pancreatitis, acute cholangitis, bile leakage and postoperative hemorrhage were not found in the SES+EPBD group, the rates of these indicators in the SES+EPBD group were significantly lower than those in the EST group (P<0.05). Conclusion SES combined with EPBD has a good therapeutic effect on larger common bile duct stones (diameter of common bile duct stone is 10–20 mm) and recurrence rate is low.

ObjectiveTo evaluate clinical outcomes of real-time ultrasound-guided percutaneous dilatational tracheostomy (PDT)for patients after cardiac surgery. MethodsFrom July 2008 to August 2012, 51 patients received tracheostomy after cardiac surgery in Nanjing Drum Tower Hospital of Nanjing University Medical School, including 20 patients after heart valve replacement, 17 patients after aortic dissection (De Bakey type I)surgery, 11 patients after coronary artery bypass grafting and 3 patients after surgical correction of congenital heart diseases. According to different surgical methods, all the patients were divided into 3 groups. In surgical tracheostomy (ST)group, there were 17 patients including 10 males and 7 females with their average age of 58.0±15.2 years. In fiberoptic bronchoscope guided PDT (FOB-PDT)group, there were 21 patients including 15 males and 6 females with their average age of 63.5±13.5 years. In real-time ultrasound-guided PDT (US-PDT)group, there were 13 patients including 7 males and 6 females with their average age of 64.5±10.2 years. Surgical outcomes were compared among the 3 groups. ResultsAll PDT operations were successfully completed. There was 1 failed patient in ST group. The incidence of bleeding was 41.18% in ST group, 9.53% in FOB-PDT group and 7.70% in US-PDT group (P=0.038). The incidence of mediastinal infection was 17.65% in ST group, 0% in FOB-PDT and US-PDT group (P=0.046). There was no statistical difference in endotracheal tube retention time, length of ICU stay and hospitalization, mortality or morbidity (hypoxemia, pneumothorax, subcutaneous emphysema)among the 3 groups. One patient in ST group developed late tracheal stenosis. ConclusionReal-time ultrasound can provide information about cervical anatomy and help choose puncture site for PDT, which can improve the safety and reduce surgical difficulty and morbidity of PDT of patients after cardiac surgery.
Objective To compare the effectiveness of arthroscopy assisted percutaneous internal fixation and open reduction and internal fixation for Schatzker types II and III tibial plateau fractures. Methods Between August 2006 and April 2010, 58 patients with tibial plateau fractures of Schatzker types II and III were treated with arthroscopy assisted percutaneous internal fixation (arthroscopy group, n=38), and with open reduction and internal fixation (control group, n=20). There was no significant difference in gender, age, disease duration, fracture type, and compl ication between 2 groups (P gt; 0.05). The operation time, incision length, fracture heal ing time, and compl ications were compared between 2 groups. Knee function score and the range of motion were measured according to American Hospital for Special Surgery (HSS) scorestandard. Results All patients achieved primary incision heal ing. The arthroscopy group had smaller incision length andlonger operation time than the control group, showing significant differences (P lt; 0.05). The patients of 2 groups were followed up 12 to 14 months. At 6 months, the HSS score and the range of motion of the arthroscopy group were significantly greater than those of the control group (P lt; 0.05). The X-ray films showed bony union in 2 groups. The fracture heal ing time of the arthroscopy group was shorter than that of the control group, but no significant difference was found (t=2.14, P=0.41). Morning stiffness occurred in 2 cases (5.3%) of the arthroscopy group, joint pain in 6 cases (30.0%) of the control group (3 cases had joint stiffness) at 1 week, which were cured after symptomatic treatment. There was significant difference in the incidence of compl ications between 2 groups (χ2=6.743, P=0.016). Conclusion The arthroscopy assisted percutaneous internal fixation is better than open reduction and internal fixation in the treatment of tibial plateau fractures of Schatzker types II and III, because it has smaller incision length and shorter fracture heal ing time.
