The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

ObjectiveTo determine the epidemiological characteristics and distributions of measles in Baoshan District， Shanghai. MethodsThis study used the measles surveillance information and reporting system to collect reported cases of measles in Baoshan District in 2005‒2021 and then conducted descriptive epidemiological methods to determine the temporality using the concentration method. ResultsIn 2005‒2021， a total of 525 measles cases were reported in Baoshan District with an average annual reported incidence rate of 1.75/10⁵， showing an overall fluctuating downward trend and obvious seasonality. The cases concentrated in 30‒39 years of age （31.24%）， 20‒29 years （28.57%）， and under 5 years （16.57%）. Majority of them were workers （18.10%）， preschool children （16.19%）， and unemployed persons （12.76%）. The incidence was significantly higher in the central region than in the other two regions for workers， preschool children， and unemployed persons （χ²=54.515， P<0.001）. Spatially， the incidence was significantly higher in the north-central sub-districts than in the south （χ²=88.103， P<0.001）. Moreover， 33.14% of measles cases did not receive measles-containing vaccine （MCV）， while 53.90% of the cases remained unknown. Additionally， uptake rate of MCV in non-local residents was significantly lower than in local residents （χ²=14.422， P<0.001）. ConclusionThe measles incidence remains remarkably low in Baoshan District of Shanghai. Young and middle-aged populations in the north-central region are susceptible to measles. It is recommended to further strengthen measles surveillance， maintain high coverage of MCV among school-age children combined with catch-up immunization for at-risk populations， and improve health education.

PURPOSE: To investigate the clinical effects of arthroscopically artificial ligament reconstruction with tensional remnant-repair in patients who are obese, and/or with demand for highly intensive sports, and/or with poor-quality ligament remnants. METHODS: A retrospective case series study was performed on patients treated by arthroscopically anterior talofibular ligament (ATFL) reconstruction with tensional remnant repair technique from January 2019 to August 2021. General data, including demographics, surgical time, and postoperative adverse events, were recorded. The American Orthopaedic Foot and Ankle Society score (AOFAS), foot and ankle ability measure (FAAM), visual analog scale (VAS), and anterior talar translation were measured preoperatively and at 6 weeks, 3 months, and 2 years postoperatively. Ultrasonography examination was performed preoperatively and 2 years postoperatively to evaluate the ATFL. Data were analyzed using SPSS 19.0. F test was used to analyze the pre- and postoperative VAS, FAAM, and AOFAS scores. The significance was set at p < 0.05. RESULTS: There were 20 males and 10 females among the patients with a mean age of (30.71 ± 5.81) years. The average surgical time was (40.21 ± 8.59) min. No adverse events were observed after surgery. At 2 years postoperatively, the anterior talar translation test showed grade 0 laxity in all patients. VAS score significantly decreased from preoperatively to 6 weeks, 3 months, and 2 years postoperatively (p < 0.001). Improvement of FAAM score and the AOFAS score from preoperatively to 6 weeks, 3 months, and 2 years postoperatively was statistically significant (p < 0.001). At 3 months postoperatively, most patients (23/30) could return to their pre-injured activities of daily living status. At 2 years postoperatively, all patients were able to return to their pre-injured activities of daily living status, and almost every patient (18/19) who expected highly intensive sports returned to sports with only 1 obese patient failing to achieve the goal. The ultrasonography examination at 2 years postoperatively showed that there was a linear band structure of soft tissue on the tension-rich fiber tape image from the fibular to the talar attachment sits of ATFL. CONCLUSION The novel arthroscopically artificial ligament reconstruction with tensional remnant-repair technique for ATFL achieved satisfactory clinical outcomes in the short and medium term after operation, and allowed early return to pre-injured activities, which could be a reliable option for patients with chronic lateral ankle instability.

Bone defects caused by different causes such as trauma, severe bone infection and other factors are common in clinic and difficult to treat. Usually, bone substitutes are required for repair. Current bone grafting materials used clinically include autologous bones, allogeneic bones, xenografts, and synthetic materials, etc. Other than autologous bones, the major hurdles of rest bone grafts have various degrees of poor biological activity and lack of active ingredients to provide osteogenic impetus. Bone marrow contains various components such as stem cells and bioactive factors, which are contributive to osteogenesis. In response, the technique of bone marrow enrichment, based on the efficient utilization of components within bone marrow, has been risen, aiming to extract osteogenic cells and factors from bone marrow of patients and incorporate them into 3D scaffolds for fabricating bone grafts with high osteoinductivity. However, the scientific guidance and application specification are lacked with regard to the clinical scope, approach, safety and effectiveness. In this context, under the organization of Chinese Orthopedic Association, the Expert consensus for the clinical application of autologous bone marrow enrichment technique for bone repair ( version 2023) is formulated based on the evidence-based medicine. The consensus covers the topics of the characteristics, range of application, safety and application notes of the technique of autologous bone marrow enrichment and proposes corresponding recommendations, hoping to provide better guidance for clinical practice of the technique.

Objective:To investigate the feasibility and clinical effects of thoracic endoscopic-assisted anterior-lateral decompression and fusion for thoracolumbar or upper lumbar disc herniation (LDH) associated with vertebral osteochondrosis (VO).Methods:From December 2017 to December 2019, 10 patients of thoracolumbar or upper LDH associated with VO were treated with thoracic endoscopic-assisted anterior-lateral decompression and fusion, including 6 men and 4 women, with an average 49.2 years old (range, 37 to 65 years old). The involved levels included T 12L 1 in 5 cases, L 1, 2 in 2 cases and L 2, 3 in 3 cases. There were 4 cases of simple thoracolumbar or upper LDH associated with VO and 6 cases of thoracolumbar or upper LDH associated with VO combined with ligamentum flavum hyperplasia and ossification or kyphosis (combined with posterior decompression and internal fixation or posterior correction surgery). The visual analogue scale (VAS), Oswestry disability index (ODI) and anterior and posterior height of intervertebral space were evaluated at follow-up. The clinical effects were evaluated according to the modified MacNab criteria. Results:The operation was performed successfully in all the patients. During the operation, the herniated disc and ossification were clearly exposed and completely removed, with the sufficient decompression of spinal cord, nerve root and dural sac. The operation duration was 115.4±23.8 minutes (range, 70 to 180 mins). Intraoperative bleed loss was 122.6±21.3 ml (range, 40 to 310 ml). The patients were followed up for averagely 21.6 months (range, 12 to 36 months). At the final follow-up, VAS score decreased from preoperative 7.2±1.9 to 1.8±1.1, and ODI decreased from preoperative 64.3%±13.9% to 16.3%±5.1% ( P<0.05). The anterior height of intervertebral space recovered from preoperative 7.8±1.5 mm to 11.9±2.3 mm, and the posterior height of intervertebral space recovered from preoperative 4.5±1.1 mm to 7.4±1.6 mm ( P<0.05). According to modified MacNab criteria, the results were excellent in 9 cases and good in 1 case. Conclusion:For thoracolumbar or upper LDH associated with VO, thoracic endoscopic-assisted anterior-lateral decompression and fusion provided clear vision of the surgical field, fully exposed and completely removed the herniated disc and ossification, which achieved satisfactory short-term results.

Objective:To investigate the long-term effects of porcine small intestinal submucosa (SIS) biologic mesh in open Lichtenstein tension-free hernia repair.Methods:The prospective randomized controlled study was conducted. The clinical data of 76 patients with unilateral inguinal hernia who underwent open Lichtenstein tension-free hernia repair in 2 medical centers (52 cases in Tianjin People′s Hospital and 24 cases in China-Japan Friendship Hospital) from August 2013 to March 2014 were selected. Based on random number method, patients were allocated into two groups. Patients undergoing Lichtenstein tension-free hernia repair using Biodesign Surgisis mesh were allocated into control group, and patients undergoing Lichtenstein tension-free hernia repair using SIS biologic mesh were allocated into experiment group. Observa-tion indicators: (1) grouping situations of the enrolled patients; (2) postoperative long-term effects. Follow-up was conducted using telephone interview, text message or mail to detect hernia recurrence or death due to other reasons as the end-point event of patients up to December 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented by M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Grouping situations of the enrolled patients: a total of 76 patients were selected for eligibility. There were 38 cases in the control group and the experiment group, respectively. The number of males and females, age, body mass index, cases with intraspinal anesthesia or local anesthesia (anesthesia method), cases with inguinal hernia on the left side or on the right side, cases classified as type Ⅰ, Ⅱ, Ⅲ, Ⅳ or Ⅴ of Gilbert classification, operation time of the control group were 35, 3, (56±15)years, (23.0±2.0)kg/m 2, 22, 16, 16, 22, 9, 16, 0, 11, 2 and (49±15)minutes, respectively. The above indicators of the experiment group were 34, 4, (54±13)years, (22.9±2.2)kg/m 2, 17, 21, 14, 24, 9, 21, 1, 7, 0, and (53±21)minutes, respectively. There was no significant difference in the above indicators between the two groups ( χ2=0.157, t=0.532, 0.367, χ2=1.317, 0.220, Z=-0.315, t=-0.765, P>0.05). (2) Post-operative long-term effects: 35 patients of the control group were followed up for (68.8±2.7)months, 4 cases of which died due to other reasons, 1 case had hernia recurrence, 1 case had chronic pain and no foreign body sensation and postoperative infection occurred. Thirty-one patients of the experiment group were followed up for (68.8±2.7)months, with no death or above complications. There was no significant difference in hernia recurrence or chronic pain between the two groups ( P>0.05). Conclusion:The long-term effects of biological mesh in open Lichtenstein tension-free hernia repair is satisfactory and there is no difference in the long-term effects between the domestic SIS biological mesh and Biodesign Surgisis mesh.

Objective To investigate the awareness rate of cognitive impairment and the needs for memory clinic in middle-aged and elderly residents in Shanghai suburb area. Methods A convenient sampling method and questionnaire survey were used in 289 outpatients in the No.1 Community Health Service Station of Dachang Community Health Service Center, Baoshan District in March 2019. Results Residents generally had less knowledge about their cognitive impairment, only 7.61% of residents were familiar with the disease.These residents who took part in the questionnaire survey showed higher interest about memory problems occurring in themselves and/or their relatives, 78.55% of them agreed that the memory test should be added in the annual physical examination for elders, and 91.35% thought that further mental examination should be taken if they had memory problems.Contrary to the large demands for memory clinic(65.05%), there was a lower awareness rate (19.03%) for medical institutions which had memory clinic. Conclusion The health promotion work related to cognitive impairment should be comprehensively carried out, and the publicity channels about memory clinic in local area or district should be increased so that residents in need can see a doctor in time.

With the spread of novel coronavirus pneumonia (NCP) in December 2019, the management and rehabilitation of elderly patients with hip fractures and protection of medical staff face new challenges, and need to be adjusted appropriately under this very circumstances. Hip fractures in the elderly account for more than half of osteoporotic fractures. Expert group formulate this consensus so as to make better decision against this epidemic and protect patients' families and medical staff. This consensus elaborates not only epidemic condition of NCP, but also general principles of medical admission, treatment and protection for both medical staff and patients, in order to provide some reference and promote the standardization of clinical diagnosis and treatment of elderly patients with hip fractures under the condition of NCP.

With aim to reasonably cope with the elderly patients with hip fracture during epidemic of corona virus disease 2019 (COVID-19), Professor Su Jiacan and Academician Zhang Yingze organized the "expert consensus on elderly patients with hip fractures under epidemic of novel coronavirus pneumonia" that for the first time formulated the management strategies for the elderly patients with hip fracture including selection of surgical methods and protective measures for medical staff from perspective of orthopedic surgeons. The authors interpret the clinical guiding value and key points of diagnosis and treatment of the consensus to help clinicians better understand the consensus and strengthen its practical application.

Objective:To explore the clinical effects of a single stage reconstruction and revascularization using a free Flow-through chimeric anterolateral thigh perforator (ALTP) flap in Gustillo III C limb injuries.Methods:From January, 2010 to December, 2017, 17 patients with Gustillo III C injury of extremities were repaired with Flow-through chimeric ALTP in emergency surgeries. The patients were 16 males and 1 female with mean age of 32.4 (19-55) years. The size of wounds ranged from 16 cm×8 cm-45 cm×30 cm. The injured arteries were Flow-through anastomosed with the descending branch of the lateral circumflex femoral artery to regain blood flow. The deep dead space was filled with vastus lateralis flap, and the skin flap and fascia flap were used for superficial covering. The donor site was closed directly in 6 patients, simultaneous skin grafts were applied in 11 patients.Results:The followed-up time ranged 5 to 60 (average 21.8) months, and conducted by clinic visits and by telephone or WeChat interviews. Fifteen flaps survived, and 2 flaps failed with limb amputated. Six patients were repaired with skin and fascia flaps and 11 patients received flaps comprising the skin, fascia and vastus lateralis muscle. Four flaps healed in stage I. Partial necrosis were observed in 11 flaps. Of which, 1 healed by change of dressing and 10 healed by skin grafting. No complications occurred in donor site in all patients.Conclusion:The Flow-through chimeric ALTP flap can be used in stage I reconstruction of the blood supply of limbs and meanwhile achieve the 3-D repair of defects. It is one of the reliable methods in the reconstruction of Gustillo III C injuries in the extremities.
