RESUMEN
Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.
RESUMEN
Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.
RESUMEN
Chronic subdural hematoma (CSDH) is a kind of common disease in neurosurgery. The traditional view is that tearing of the bridging vein is the main pathogenesis of traumatic brain injury. CSDH induced by leukemia is rarely reported, and its pathogenesis remains unclear. Diagnosis and treatment become difficult because of its combination with hematological system tumor, enjoying high mortality and disability rate. In view of close relationship between these 2 diseases, treatment should be simultaneous without priority. This paper reviews the pathogenesis, clinical manifestations, auxiliary examinations and treatments of CSDH caused by leukemia, and provides suggestions for clinical management of this kind of disease.
RESUMEN
Since December 2019, novel coronavirus pneumonia (NCP) has been reported in Wuhan, Hubei Province, and spreads rapidly to all through Hubei Province and even to the whole country. The virus is 2019 novel coronavirus (2019-nCoV), never been seen previously in human, but all the population is generally susceptible. The virus spreads through many ways and is highly infectious, which brings great difficulties to the prevention and control of NCP. Based on the needs of orthopedic trauma patients for emergency surgery and review of the latest NCP diagnosis and treatment strategy and the latest principles and principles of evidence-based medicine in traumatic orthopedics, the authors put forward this expert consensus to systematically standardize the clinical pathway and protective measures of emergency surgery for orthopedic trauma patients during prevention and control of NCP and provide reference for the emergency surgical treatment of orthopedic trauma patients in hospitals at all levels.
RESUMEN
With the outbreak of novel coronavirus pneumonia (NCP) induced by 2019 novel coronavirus (2019-nCoV) in Wuhan, Hubei Province in December 2019, more and more suspected or confirmed cases have been found in various regions of China. Although China has adopted unprecedented strict quarantine and closed management measures to prevent the spreading of the disease, Department of Traumatic Orthopedics may still have to manage NCP patients with open fractures or severe trauma that require emergency surgery. Therefore, the identification and management of 2019-nCoV infection as soon as possible as well as the protection of all medical staff involved in the emergency treatment of patients are the severe challenges faced by orthopedic traumatologists during the prevention and control of NCP. Based on the characteristics of such patients and related diagnosis and treatment experiences during the epidemic of NCP, the authors formulate the surgical management strategies for orthopedic trauma patients.
RESUMEN
Objective:To explore the effects of treadmill training during pregnancy on the development of dendritic spines and the expression of brain-derived neurotrophic factor (BDNF) in hippocampal neurons of offspring rats.Methods:According to the random number table, the natural pregnant healthy SPF female rats were divided into control group (CON group) and treadmill training group (TE group), with 6 rats in each group. The pregnant rats in CON group were fed quietly, while those in TE group were given treadmill exercise intervention 60 minutes a day with 5 days a week for 3 weeks. The setting parameters of treadmill training: the slope of electric flat plate was 0°, the track transmission speed was 8 m/min in the first 5 min, 10 m/min in the middle 25 min, and 12 m/min in the last 30 min.The body weight changes of pregnant rats in the two groups were recorded every two days from gestation of 0 day (G0). On day 21 of gestation (G21), the pregnant mice were placed in a quiet environment for labor. The expression of BDNF in hippocampus was detected by Western blot at 0, 7, 14 and 28 days after birth (P0, P7, P14, P28) respectively. The density of dendritic spines in hippocampus was detected by Golgi staining on P28. SPSS 19.0 software was used to analyze the data. Repeated measurement ANOVA was used to analyze the body weight of pregnant rats. t-test was used to analyze the data of neuronal dendritic spines. Results:Golgi staining showed that at P28, the density of dendritic spines in hippocampal CA1 area of TE group(11.330±0.558) was significantly higher than that of CON group (9.667±0.422), and the difference was statistically significant ( t=2.384, P<0.05). Compared with CON group, the relative expression level of BDNF protein in the hippocampus of offspring rats of TE group was significantly higher at P0: ((1.001±0.206), (2.027±0.240), t=3.244, P<0.05), P7: ((1.003±0.152), (2.077±0.172), t=4.669, P<0.05), P14: ((1.005±0.160), (1.562±0.178), t=3.329, P<0.05) and P28: ((1.004±0.196), (1.790±0.191), t=2.875, P<0.05), and the differences were statistically significant. Conclusion:Treadmill training during pregnancy can promote the development of dendritic spines in hippocampal neurons of offspring rats, which may be related to the promotion of BDNF expression in hippocampus.

RESUMEN
Objective@#To evaluate Herbert screwing directly via the anterior approach for femoral head fractures of Pipkin type Ⅱ in the youth.@*Methods@#A retrospective analysis was conducted of the 16 patients who had been treated at Department of Orthopaedics, Union Hospital, Tongji Medical College for femoral head fractures of Pipkin type Ⅱ from August 2016 to June 2018. They were 9 men and 7 women, aged from 18 to 45 years (mean, 25.6 years). Of them, 10 cases who had been complicated with posterior dis-location of the hip received emergency hip reduction(<6 h) before surgical fixation. All the patients underwent Herbert screwing directly via the anterior approach. Their incision length, operation time, intraoperative blood loss, hospitalization time, Harris hip scores, therapeutic efficacy and complications were recorded.@*Results@#In this series, the incision length averaged 10.4 cm, operation time 45.6 min, intraoperative blood loss 46.5 mL, and hospitalization time 4.0 d. All the 16 patients were followed up for 11 to 15 months (average, 12.7 months). Their Harris hip scores at preoperation, 3, 6 and 9 months postoperation and at the last follow-up were, respectively, 14.3±2.2, 64.8±2.4, 81.1±4.9, 88.1±4.6 and 91.9±3.4 points, showing a significant difference between any 2 time points (P<0.05). The therapeutic efficacy at the last follow-up by the Thompson-Epstein clinical evaluation was assessed as excellent in 9 cases, as good in 6 and as fair in one. No osteonecrosis of the femoral head or heterotopic ossification was observed by follow-up.@*Conclusion@#For young patients with femoral head fracture of Pipkin type Ⅱ, Herbert screwing directly via the anterior approach provides easy exposure and manipulation, does not aggravate the blood supply to the femoral head, decreases incidence of heterotopic ossification, and leads to shorter operation time and quick functional recovery of the hip.
RESUMEN
Most patients with chronic subdural hematoma (CSDH) have a history of craniocerebral trauma. Avulsion of intracranial pontine vein is the main pathogenesis after craniocerebral injury. CSDH drilling and drainage is the most widely used surgical method, with low recurrence and mortality rate. However, the postoperative complication of subdural pyometra is extremely rare, which leads to high mortality and disability rate and thus representing a very challenging disease in trauma surgery. Old age, diabetes mellitus, drainage with foreign body, craniocerebral surgery, open wound, chronic systemic infectious diseases (sinusitis, otitis media, abdominal abscess, lung infection, urinary tract infection), tumor or immune deficiency diseases are all the high risk factors. This paper reviews the pathogenesis, pathogenic bacteria, clinical manifestations, auxiliary examination, treatment and prognosis of subdural empyema after CSDH drilling and drainage in recent years, and provides suggestions for clinical management.

RESUMEN
Objective To evaluate the effects of isoflurane postconditioning on mitochondrial permeability transition pore (mPTP) in brain tissues of neonatal rats with hypoxic-ischemic brain injury.Methods One hundred and twenty 7-day-old Sprague-Dawley rats,weighing 12-16 g,were randomly divided into 4 groups (n =30 each) using a random number table:sham operation group (group S),isoflurane group (group I),hypoxicischemic brain injury group (group HIBI),and hypoxic-ischemic brain injury + isoflurane postconditioning group (group HI).To establish hypoxic-ischemic brain injury model in the neonatal rats,the left common carotid artery ligation was carried out,and then the rats were exposed to 8％ O2 + 92％ N2 at 37 ℃ for 2 h in HIBI and HI groups.The rats inhaled 1.5 ％ isoflurane for 30 min after the model was established in group HI.The rats only inhaled 1.5％ isoflurane for 30 min in group I.At 24 h after the model was established,10 rats taken out randomly in each group were sacrificed and brains were removed to detect mPTP opening.At 7 days after the model was established,the survival rate was recorded in the rest rats.The rats were then sacrificed and brains were removed and the right and left cerebral hemispheres were weighed separately,and the ratio between left/right cerebral hemispheres was calculated.The density of normal neurons in ventral posterior inferior thalamic nucleus and hippocampal CA3 region in the left and right cerebral hemispheres were measured and the ratios of the density of normal neurons in the left to right cerebral hemisphere were calculated.Results There was no significant difference in the survival rate between the four groups (P ＞ 0.05).Compared with group S,the ratios of the density of normal neurons in the left to right cerebral hemisphere,weight of left cerebral hemisphere,and ratio between left/right cerebral hemispheres were significantly decreased,and mPTP opening was increased in group HIBI (P ＜ 0.05),and no significant changes were found in the parameters mentioned above in group I (P ＞ 0.05).Compared with group HIBI,the ratios of the density of normal neurons in the left to right cerebral hemisphere,weight of left cerebral hemisphere,and ratio between left/right cerebral hemispheres were significantly increased,and mPTP opening was decreased in group HI (P ＜ 0.05).Conclusion The mechanism by which isoflurane postconditioning reduces hypoxic-ischemic brain injury may be related to inhibition of mPTP opening in brain tissues of neonatal rats.
