Objective To summarize the research progress of surgical treatment for anterior shoulder dislocation and combined injuries. Methods The related literature was reviewed, and the surgical treatment options for the anterior shoulder dislocation and its combined injuries were summarized. Results Anterior shoulder dislocation can combine with anteroinferior capsular ligament complex injury (Bankart injury), bony Bankart defect, and Hill-Sachs lesion. For Bankart and bony Bankart injuries, arthroscopic repair or coracoid osteotomy combined with bony graft reconstruction can be performed. For Hill-Sachs lesion, conservative treatment, soft tissue repair, or bony reconstruction should be selected based on the extent of the bone defect. For bipolar injury, the Bankart repair, Remplissage, or arthroplasty should be selected based on the extent of the glenoid defect. Conclusion With the development of arthroscopy and the improvement of the surgical concept, there is a complete set of surgical options for various injuries of the anterior shoulder dislocation. When choosing a surgical procedure, the patient’s specific injury and age, exercise level, and other relating factors should be comprehensively assessed in order to achieve the best results.
Objective To explore the feasibility of pre-implantation of high-intensity suture into tendon grafts to prevent postoperative graft relaxation and creep in anterior cruciate ligament (ACL) reconstruction. Methods Thirty-six specimens of ACL reconstruction graft were made using adult swine’s Achilles tendon. All the specimens were randomly divided into experimental group (groups A and C) and control group (groups B and D), 9 specimens each group. One double-strand Ultrabraid No.2 high-intensity suture was pre-implanted into the grafts of groups A and C. Groups A and B underwent a 1 000-cycles load test while groups C and D underwent a 3 000-cycles load test. Then a pull-out test was performed until failure. The displacements at different cycles (100, 500, 1 000, 2 000, and 3 000) in all groups and yield loads of groups C and D were measured and analyzed. Results The displacement of group A was significantly smaller than that of group B at the cycles of 100, 500, and 1 000 (P<0.05); the displacement of group C was significantly smaller than that of group D at every cycle (P<0.05). Additionally, the yield load of group C was significantly higher than that of group D (t=4.816,P=0.001). Conclusion Pre-implantation of high-intensity suture into tendon grafts play an important role in the prevention of postoperative graft creep and relaxation in ACL reconstruction.
Objective To summarize the research progress of the treatment of primary hyperparathyroidism (PHPT) in multiple endocrine neoplasm type 1 (MEN1). Method The literature about the treatment of PHPT in MEN1 in recent years was reviewed. Results When the symptoms of MEN1 related PHPT were obvious, surgery was an effective treatment. In addition to conventional total parathyroidectomy with autotransplantation and subtotal parathyroidectomy, less-than subtotal parathyroidectomy, and single gland excision had also been proved to be effective recently. Conclusions Combining the clinical manifestations with the actual involvement of the parathyroid of MEN1 related PHPT patients, personalized selection of appropriate timing and methods of parathyroidectomy can help MEN1 related PHPT patients obtain ideal parathyroid function and ensure the quality of life to the greatest extent.
ObjectiveTo summarize the results of surgical treatment for 79 patients with coarctation of the aorta (CoA) combined with complex anomalies (CA) in recent years.MethodsThe data from 79 patients with CoA combined with CA admitted to Guangzhou Women and Children's Medical Center between January 19, 2010 and September 7, 2017 were collected and analyzed. There were 52 males and 27 females. The median age was 71 days, and the median weight was 4.3 kg. There were 26 patients combined with tracheostenosis and 7 patients with preoperative tracheal intubation. Extended end-to-side anastomosis was used to correct the CoA, and the associated cardiac abnormalities were treated simultaneously by an incision through median sternotomy. All operations were performed by the same group of surgeons.ResultsThe median deep hypothermic circulatory arrest was 18 (13-28) minutes, the median aorta cross-clamp time was 62 (15-199) minutes, the median cardiopulmonary bypass time was 145 (71-674) minutes, the median ventilation time was 72 (9-960) hours, the median length of ICU stay was 144 (12-1 944) hours, and the median length of hospital stay was 24 (2-93) days. Early death occurred in 9 patients and late death occurred in 5 patients. Reoperation occurred in 28 patients and recoarctation developed in 10 patients. After operation, transcoarctation gradient was reduced, and the transcutaneous oxygen saturation, C-reactive protein (CRP), lactate and creatinine were increased. Compared to the survival group, both preoperative and postoperative transcutaneous oxygen saturation were worse and the postoperative levels of plasma brain natriuretic peptide (BNP) and CRP were higher in the death group.ConclusionCorrecting the CoA and the associated CA simultaneously with extended end-to-side anastomosis by an incision through median sternotomy is effective and safe, and the outcomes of immediate and medial-term are satisfactory. Improving oxygenation and limiting elevation of BNP and CRP levels may reduce the death rate.
ObjectiveTo study the safety of right vertical infra-axillary thoracotomy (RVIAT) in the repair of ventricular septal defect (VSD) and the optimal age for RVIAT.MethodsBetween June 2014 and June 2018, 441 children underwent VSD repair via RVIAT in our hospital. According to the age, they were divided into four groups: a 4 months to 1 year old group (R1 group, n=123), a 1-2 years old group (R2 group, n=106), a 2-5 years old group (R3 group, n=166), a >5 years old group (R4 group, n=46). The clinical effects of the patients were compared.ResultsAll the operations were successfully performed and no serious complication was found in all groups. No statistical difference was observed in the operation time, blood loss during operation, thoracic drainage 24 h after operation among groups (P>0.05). The cardiopulmonary bypass time, aortic cross-blocking time and ICU stay time in the R1 and R2 groups were longer than those in the R3 and R4 groups (P<0.05). In the R1 group, the postoperative ventilating time and postoperative hospital stay time were longer, and the blood transfusion volume was more than those in the R3 and R4 groups (P<0.05). The incidence of postoperative complications was higher in the R4 group than that in the R1 and R3 groups (P<0.05).ConclusionVSD repair via RVIAT may be more effective in children >2 years old, and 2-5 years old may be the optimal age.
The patient, male, 1 year, was admitted to our hospital with cardiac murmur. Cardiac ultrasonography showed "complete atrioventricular septal defect (C-AVSD), secondary orifice atrial septal defect (ASD), patent ductus arteriosus (PDA), left superior vena cava, and pulmonary hypertension". The patient got follow-up at the age of 3, 6, 9 months and 1 year, with no feeding difficulties, no obvious underdevelopment and no history of repeated respiratory infections. Cardiac ultrasonography showed that the ventricular septal defect (VSD) healed spontaneously at 9 months of age. At 1 year of age, he was admitted to the hospital with "partial atrioventricular septal defect (P-AVSD)" and accepted surgery. Intraoperative exploration showed that the primary orifice ASD was 12 mm, the atrioventricular valve was divided into two groups, and the left atrioventricular valve had three leaflets: anterior, posterior, and lateral one. A cleft was between the anterior and posterior leaflets. The annulus was not enlarged with diameter of 13 mm. The right atrioventricular valve developed well, with fibrous hyperplasia and adhesion under the septal valve. No VSD was seen. The cleft was sutured intermittently. Autologous pericardial patch was used to repair the primary orifice ASD, and the coronary sinus was separated into the right atrium. Self-healing of VSD patients with C-AVSD is very rare, suggesting that patients with C-AVSD with normal range of development, and without obvious clinical symptoms and secondary damage, should be followed up and accept elective surgery in clinical practice.
ObjectiveTo investigate the method of treating tuberculosis in the craniovertebral junction and its effectiveness.MethodsThe clinical data of 18 patients with tuberculosis in the craniovertebral junction between July 2010 and January 2019 was analyzed retrospectively. There were 14 males and 4 females, aged 21 months to 75 years (median, 35 years). The disease duration ranged from 2 weeks to 60 months (median, 4 months), and the affected segment was C0-C3. Preoperative visual analogue scale (VAS) score was 6.7±1.5 and the Japanese Orthopaedic Association (JOA) score was 16.1±1.8. The American Spinal Cord Injury Association (ASIA) grading system was applied to classify their neurological functions, according to which there were 6 cases of grade D and 12 cases of grade E. Among 18 patients, 4 patients underwent conservative treatment, 1 patient removed tuberculosis via transoral approach, 1 patient removed tuberculosis via posterior cervical approach, and 12 patients removed tuberculosis via transoral approach immediately after posterior cervical (atlantoaxial or occipitalcervical) fusion and internal fixation. The VAS score, ASIA grading, and JOA score were applied to evaluate effectiveness. X-ray film, CT, and MRI were taken after treatment to evaluate the tubercular recurrence, cervical stability, and bone healing.ResultsAll the patients were followed up 3 to 42 months (median, 12 months). At 3 months after treatment, the VAS score was 1.7±1.0, showing significant difference when compared with preoperative score (t=15.000, P=0.000); and the JOA score was 16.7±1.0, showing no significant difference when compared with preoperative score (t=1.317, P=0.205). According to ASIA grading, 6 patients with grade D before treatment had upgraded to grade E after treatment, while the remaining patients with grade E had no change in grading. The imaging examinations showed the good stability of the cervical spine. All patients had complete tuberculosis resection and no recurrence, and the patients who underwent internal fixation via posterior cervical approach achieved atlantoaxial or occipitalcervical bone fusion.ConclusionOn the premise of regular chemotherapy, if there is no huge abscess causing dysphagia or dyspnea, atlantoaxial instability, and neurological symptoms, patients can undergo conservative treatment. If not, however, the transoral approach can be used to completely remove the tuberculosis lesion in the craniovertebral junction. One-stage debridement via transoral approach combined with posterior cervical fusion and internal fixation can achieve satisfactory effectiveness.
Objective To investigate the safety and efficacy of preoperative ultra-short-course chemotherapy combined with surgical treatment of chest wall tuberculosis. Methods The clinical data of 216 patients with chest wall tuberculosis from January 2013 to June 2016 in our hospital were retrospectively analyzed, including 121 males and 95 females with an average age of 35±15 years (range, 4-74 years). Results All patients were treated with anti-tuberculosis drugs for 17.0±11.3 days preoperatively, including 12.5±5.0 days in simple chest wall tuberculosis and 19.4±12.3 days in combined chest wall tuberculosis. The postoperative recurrence rate of chest wall tuberculosis was 3.7%, which was close to or lower than that of routine preoperative antituberculous therapy in patients with ultra-short-course anti-tuberculosis treatment before surgery. Conclusion Preoperative ultra-short-course chemotherapy combined with surgical treatment for chest wall tuberculosis will not increase the recurrence rate of chest wall tuberculosis, and can effectively shorten the hospital stay. Timely adjustment of anti-tuberculosis chemotherapy based on thorough debridement, postoperative drugs, not the preoperative drugs, is the key to reinforce the surgical outcome.
ObjectiveTo explore the short-term efficacy and safety of Ozaki surgery in treating adult patients with aortic valve disease and to summarize clinical experience. MethodsClinical data of adult patients with aortic valve disease who underwent Ozaki surgery in the Department of Cardiovascular Surgery, Beijing Anzhen Hospital of Capital Medical University Nanchong Branch in 2025 were collected, and the effectiveness and safety of Ozaki surgery were analyzed. ResultsA total of 5 patients were included, including 3 males and 2 females, with an average age of (47.80±12.99) years. One patient was aortic stenosis, 2 patients were aortic regurgitation, and 2 patients were aortic stenosis combined with regurgitation. Two patients underwent isolated Ozaki surgery, 1 patient underwent Ozaki+coronary artery bypass surgery, and 2 cases underwent Ozaki+mitral valve plasty+tricuspid valve plasty. The average operation time was (6.70±1.25) hours. The average extracorporeal circulation time was (217.20±59.47) minutes, the average aortic cross-clamping time was (153.60±45.71) minutes, the average postoperative ventilator support time was (25.00±11.79) hours, the average intensive care unit stay was (2.43±1.30) days, and the average postoperative hospital stay was (11.20±1.92) days. The postoperative average aortic valve flow rate was (1.70±0.26) m/s, and the average transvalve pressure gradient was (11.00±1.87) mm Hg. Postoperatively, 3 patients had no aortic regurgitation, and 2 patients had trace regurgitation. Postoperative complications included pulmonary infection in 3 patients, severe pneumonia in 1 patient, liver function damage in 4 patients, and renal function damage in 3 patients. No patients experienced arrhythmias or other complications. All 5 patients recovered and were discharged, and their cardiac function significantly improved postoperatively compared to preoperatively (P<0.001), with both left ventricle (P=0.047) and left atrium (P=0.016) reduced in size. ConclusionThe short-term results of Ozaki surgery for adult patients with aortic valve disease are satisfied, but long-term outcomes still need further exploration.
Objective To review the biomechanical research progress of internal fixation of tibial plateau fracture in recent years and provide a reference for the selection of internal fixation in clinic. Methods The literature related to the biomechanical research of internal fixation of tibial plateau fracture at home and abroad was extensively reviewed, and the biomechanical characteristics of the internal fixation mode and position as well as the biomechanical characteristics of different internal fixators, such as screws, plates, and intramedullary nails were summarized and analyzed. Results Tibial plateau fracture is one of the common types of knee fractures. The conventional surgical treatment for tibial plateau fracture is open or closed reduction and internal fixation, which requires anatomical reduction and strong fixation. Anatomical reduction can restore the normal shape of the knee joint; strong fixation provides good biomechanical stability, so that the patient can have early functional exercise, restore knee mobility as early as possible, and avoid knee stiffness. Different internal fixators have their own biomechanical strengths and characteristics. The screw fixation has the advantage of being minimally invasive, but the fixation strength is limited, and it is mostly applied to Schatzker typeⅠfracture. For Schatzker Ⅰ-Ⅳ fracture, unilateral plate fixation can be used; for Schatzker Ⅴand Ⅵ fracture, bilateral plates fixation can be used to provide stronger fixation strength and avoid the stress concentration. The intramedullary nails fixation has the advantages of less trauma and less influence on the blood flow of the fracture end, but the fixation strength of the medial and lateral plateau is limited; so it is more suitable for tibial plateau fracture that involves only the metaphysis. Choosing the most appropriate internal fixation according to the patient’s condition is still a major difficulty in the surgical treatment of tibial plateau fractures. Conclusion Each internal fixator has good fixation effect on tibial plateau fracture within the applicable range, and it is an important research direction to improve and innovate the existing internal fixator from various aspects, such as manufacturing process, material, and morphology.
