Objective To investigate arthroscopic treatment for acute acromioclavicular dislocation by using Twin Tail TightRope combined with distal joint capsular repair. Methods The clinical data of 40 patients with acromioclavicular dislocation treated between February 2016 and December 2017 were retrospectively analyzed. The patients were divided into arthroscopic group (20 cases, using arthroscopic Twin Tail TightRope combined with distal joint capsular repair for anatomical repair of stable structure of acromioclavicular joint) and control group (20 cases, treated with clavicular hook plate internal fixation) according to different surgical methods. There was no significant difference in gender, age, cause of injury, Rockwood classification, time from injury to operation, preoperative visual analogue scale (VAS) score and Constant score between the two groups (P>0.05), which were comparable. Postoperative VAS score and Constant score were used to assess shoulder function and re-dislocation was also observed. Results The incisions of the two groups healed by first intention, and no early postoperative complications occurred. All patients were followed up 12-18 months (mean, 13.5 months). Postoperative X-ray films showed good anatomical reduction in both groups, but the clavicular hook had a presense in the subacromial space in control group. All patients in arthroscopic group achieved satisfactory shoulder function and returned to work after operation; there was no obvious pain, no complications such as exposure of implant after operation, and no need to remove the implant. In the control group, 4 patients had obvious subacromial impingement pain after operation, and 1 patient had re-dislocation after removal of internal fixator at 1 year after operation; the rest had no complications related to internal fixation, and the internal fixators were removed at 1.0-1.5 years after operation, without re-dislocation. The VAS score and Constant score at 3 months and 1 year after operation in both groups significantly improved when compared with those before operation, and further improved at 1 year after operation (P<0.05). The VAS score and Constant score at 3 months and 1 year after operation in arthroscopic group were significantly better than those in control group (P<0.05). Conclusion Arthroscopic treatment for acute acromioclavicular joint dislocation by using Twin Tail TightRope combined with distal capsular repair is more effective than traditional incision surgery and can obtain more satisfactory results in patient compliance and function recovery because of minimally invasive surgery.
ObjectiveTo investigate the effectiveness of Nice knot combined with elastic intramedullary nailing fixation in treatment of Robinson type 2B midshaft clavicular fracture in adults.MethodsBetween March 2016 and January 2018, 20 patients with Robinson type 2B midshaft clavicular fractures were treated with reduction and internal fixation by Nice knot and elastic intramedullary nailing. There were 13 cases and 7 cases, with an average age of 43 years (range, 18-56 years). The causes of injury included the traffic accident in 6 cases, falling in 12 cases, and falling from height in 2 cases. The interval between injury and admission ranged from 1 hour to 2 days (mean, 3.2 hours). The fractures were classified as Robinson type 2B1 in 16 cases and type 2B2 in 4 cases. The length of incision, the operation time, the visual analogue scale (VAS) score on the 2nd day after operation, the fracture healing time, the postoperative shoulder function and the Disability of Arm Shoulder and Hand (DASH) score, the complications, and the time of second surgical removal of internal fixator and incision length were recorded.ResultsThe length of incision was 2-6 cm (mean, 4.7cm). The operation time was 45-120 minutes (mean, 77.2 minutes). The VAS score was 1-5 (mean, 3.2) on the 2nd day after operation. All incisions healed by first intention and no infection or nerve injury occurred. All patients were followed up 12-32 months (mean, 18.6 months). All fractures healed with the healing time of 10-15 weeks (mean, 12.1 weeks). The Constant score was 92-98 (mean, 96.3) and DASH score was 0-6.4 (mean, 3.1). The elastic intramedullary nailing bending and hypertrophic nonunion occurred in 1 case and the skin stimulated by elastic nail tail in 1 case after operation. The internal fixators were removed at 12-26 months (mean, 14.6 months) after operation. And the length of incision was 1-2 cm (mean, 1.3 cm) and the operation time was 5-15 minutes (mean, 9.0 minutes). ConclusionFor the midshaft clavicular fracture in adults, the procedure of the Nice knot combined with elastic intramedullary nail has advantages of small incision, light pain, rapid fracture healing, small secondary operation injury, and avoiding the risk of clavicular epithelial nerve injury, and can obtain good effectiveness.
ObjectiveTo investigate the safety and effectiveness of the multi-artery graf tstrategy for coronary bypass (MICS-CABG) with small incision in the left chest, and to provide experience for the promotion of this technique.MethodsThe clinical data of 64 patients with MICS-CABG in Department of Cardiac Surgery of Peking University Third Hospital from December 2015 to November 2019 were retrospectively analyzed. There were 54 males and 10 females, aged 36-77 (61.1±8.7) years. The left lateral thoracic incision (5-8 cm) was made through the 5th intercostal incision, and the operation was performed under off-pump CABG. With the help of the chest wall suspension device and the heart fixator, the proximal anastomosis of the ascending aorta, anastomosis of the target vessels of the left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) systems were completed. The number of grafts was 2-4 (2.3±0.5) including 2 grafts in 45 patients, 3 grafts in 17 patients and 4 grafts in 2 patients. Three patients were treated with percutaneous intervention (PCI) hybridization and 62 patients were treated with total artery bypass graft. Coronary angiography was performed within 7 days after the operation to evaluate the graft patency rate. The incidence of major adverse cardiac and cerebrovascular events (MACCE) was recorded in the follow-up. The MACCE rate was calculated by Kaplan-Meier method.ResultsNone of the patients was transferred to thoracotomy and no intra-aortic balloon counterpulsation (IABP) or extracorporeal membrane oxygenation (ECMO) was used during the operation. Incision infection was in 1 patient and reoperation in 2 patients (all were postoperative hemorrhage). Within 30 days after surgery, MACCE occurred in 1 patient, including 1 patient of non-fatal myocardial infarction. The overall patency rate of angiography bypass was 96.2%, and the patency rate of anterior descending branch bypass was 98.2%. Follow-up was performed from 12 to 60 months (median follow-up time was 28 months). The loss rate was 7.8% (5/64). The incidence of MACCE was 84.9% (95%CI 79.5%-90.3%).ConclusionThe MICS-CABG can achieve completed re-vascularization and totally artery-CABG and the short-term and medium-term clinical results of the operation are good.
ObjectiveTo evaluate the effectiveness of robot-guided percutaneous fixation and decompression via small incision in treatment of advanced thoracolumbar metastases. Methods A clinical data of 57 patients with advanced thoracolumbar metastases admitted between June 2017 and January 2021 and met the selection criteria was retrospectively analyzed. Among them, 26 cases were treated with robot-guided percutaneous fixation and decompression via small incision (robot-guided group) and 31 cases with traditional open surgery (traditional group). There was no significant difference in gender, age, body mass index, lesion segment, primary tumor site, and preoperative Tokuhashi score, Tomita score, Spinal Instability Neoplastic Score (SINS), visual analogue scale (VAS) score, Oswestry disability index (ODI), Karnofsky score, and Frankel grading between groups (P>0.05). The operation time, hospital stays, hospital expenses, intraoperative blood loss, postoperative drainage volume, duration of intensive care unit (ICU) stay, blood transfusion, complications, and survival time were compared. The pedicle screw placement accuracy was evaluated according to the Gertzbein-Robbins grading by CT within 4 days after operation. The pain, function, and quality of life were evaluated by VAS score, ODI, Karnofsky score, and Frankel grading. Results During operation, 257 and 316 screws were implanted in the robot-guided group and the traditional group, respectively; and there was no significant difference in pedicle screw placement accuracy between groups (P>0.05). Compared with the traditional group, the operation time, hospital stays, duration of ICU stay were significantly shorter, and intraoperative blood loss and postoperative drainage volume were significantly lesser in the robot-guided group (P<0.05). There was no significant difference in hospital expenses, blood transfusion rate, and complications between groups (P>0.05). All patients were followed up 8-32 months (mean, 14 months). There was no significant difference in VAS scores between groups at 7 days after operation (P>0.05), but the robot-guided group was superior to the traditional group at 1 and 3 months after operation (P<0.05). The postoperative ODI change was significantly better in the robot-guided group than in the traditional group (P<0.05), and there was no significant difference in the postoperative Karnofsky score change and Frankel grading change when compared to the traditional group (P>0.05). Median overall survival time was 13 months [95%CI (10.858, 15.142) months] in the robot-guided group and 15 months [95%CI (13.349, 16.651) months] in the traditional group, with no significant difference between groups (χ2=0.561, P=0.454) . Conclusion Compared with traditional open surgery, the robot-guided percutaneous fixation and decompression via small incision can reduce operation time, hospital stays, intraoperative blood loss, blood transfusion, and complications in treatment of advanced thoracolumbar metastases.
ObjectiveTo analyze the clinical efficacy of right midaxillary straight incision surgery in the treatment of doubly committed subarterial ventricular septal defect. MethodsThe clinical data of children with doubly committed subarterial ventricular septal defect who received surgeries in our hospital from August 2020 to July 2023 were analyzed retrospectively. All the children underwent surgical repair and were divided into two groups according to the incision position, including a right midaxillary straight incision group and a median incision group. The outcomes were compared between the two groups. ResultsA total of 187 patients were enrolled. There were 102 patients in the right midaxillary straight incision group, including 55 males and 47 females with a median age of 26.0 (5.0, 127.0) months and a median weight of 12.5 (5.1, 32.8) kg at surgery. There were 85 patients in the median incision group, including 37 males and 48 females with a median age of 4.0 (2.0, 168.0) months and a median weight of 6.7 (4.8, 53.9) kg at surgery. No mortality occurred in the study. There was no statistical difference between the two groups in the cardiopulmonary bypass time (50.0±18.4 min vs. 46.1±15.7 min) or aortic cross-clamping time (31.3±18.6 min vs. 26.3±17.5 min) (P>0.05). Compared to the median incision group, the time from the end of cardiopulmonary bypass to the closure of chest (22.3±15.6 min vs. 37.1±13.4 min, P=0.001), postoperative hospital stay (6.9±3.9 d vs. 8.6±3.6 d, P=0.002), the length of incision (4.3±2.7 cm vs. 8.5±3.2 cm, P=0.001), drainage volume (79.0±32.2 mL vs. 100.2±43.1 mL, P=0.001), and the pain score on the 2nd and the 3rd day after the operation were statistically better in the right midaxillary straight incision group (P<0.05). The medical experience and incision satisfaction scores at discharge were higher than those in the median incision group (P<0.05). During the follow-up of 21.0 (1.0, 35.0) months, no residual shunt was detected and all patients in both groups had a normal cardiac function and mild or less valve regurgitation. ConclusionCompared to the median incision, minimally invasive right midaxillary straight incision is equally safe and reliable in the treatment of doubly committed subarterial ventricular septal defect with the advantages of cosmetic and fast recovery.
