ObjectiveTo summarize the relationship between lateral femoral notch sign (LFNS) and anterior cruciate ligament (ACL) rupture. MethodsThe relevant literature of LFNS at home and abroad in recent years was retrospectively reviewed, and its mechanism, diagnostic criteria and influencing factors in diagnosis of ACL rupture were summarized and analyzed.ResultsThe LFNS is associated with rotational stability of the knee. As an indirect sign of ACL rupture, the LFNS has high clinical diagnostic value, especially the diagnosis of ACL rupture with lateral meniscus injury.ConclusionThe diagnostic criteria and influencing factors of LFNS in diagnosis of ACL rupture are still unclear and controversial, which needs further study.
ObjectiveTo summarize the clinical progress of minimally invasive techniques in treatment of pilonidal disease.MethodThe relevant literatures about minimally invasive techniques in the treatment of pilonidal disease in recent years were reviewed.ResultsAbout hair removal and carbolic acid injection, they had less damage, fewer complications, higher recurrence rate compared to other surgery, and did not affect the second treatment. The fibrin injection could not clarify its role in the treatment of pilonidal disease due to some defects in the clinical design. Bascom Ⅰhad the advantages of fast recovery and no need for hospitalization, with a recurrence rate of 8%–16%. According to the results of some current clinical researches, it was a promising operation. Sinus resection required further clinical evaluation due to the limited results of current researches. A clinical study of more than 1 000 cases over 10 years showed that the recurrence rate in 10 years was 16%. Compared with frequently used pilonidal operations, the trephine technique was associated with a lower recurrence rate and a lower incidence of postoperative complication. Some short-term clinical researches showed that endoscopic pilonidal sinus treatment was a safe, minimally invasive, and less complication treatment.ConclusionsCompared with frequently used pilonidal operations, minimally invasive technique has the advantages of shortening the hospital stay, shortening the healing time, and reducing complications. It is worth of application.
Although the incidence of gastrointestinal hemorrhage after cardiac surgery is low, the mortality rate is high. Early detection and diagnosis of gastrointestinal hemorrhage are difficult. The high risk phases including preoperation, intraoperation and postoperation. Preoperative high risk comorbidities include gastrointestinal ulcer, hypertension, coronary heart disease and chronic renal failure. Intraoperative high risk factors include decreased gastrointestinal blood perfusion due to cardiopulmonary bypass, inflammatory factors releasing, coagulation disorders, and thrombosis. Postoperative high risk factors include hypotension, low cardiac output, prolonged mechanical ventilation, etc. This article retrospectively summarized high-risk factors and pathogenesis of gastrointestinal hemorrhage after cardiac surgery, in order to improve prevention and treatment of gastrointestinal hemorrhage.
ObjectiveTo summarize the research progress in creep characteristics of lumbar intervertebral disc.MethodsThe relevant literature at home and abroad was systematically searched. Then, the concept and structural basis of lumbar disc creep, the description of creep characteristics, and the latest progress of its influencing factors were summarized and analyzed.ResultsThe intervertebral disc is viscoelastic. After loading, the deformation increases with time. However, the degree of increase is not linear with time. That is creep, which plays an important role in buffering the load generated by human activities and absorbing energy in order to maintain stable movement of the spine. Both experimental and simulation studies can well describe the creep behavior of intervertebral disc. Various models including standard linear solid model and corresponding constitutive equations can quantify and compare the creep characteristics, which can be obviously changed by the degeneration of intervertebral disc and the mode of loading stress.ConclusionCreep is an important mechanical properties of intervertebral discs, and an in-depth understanding of the creep characteristics of lumbar intervertebral discs is of great guiding significance for the intervention and treatment of low back pain.
ObjectiveTo summarize the clinical application and research progress in unicompartmental knee arthroplasty (UKA).MethodsThe literature related to UKA in recent years was reviewed and the emerging indications, implant options, comparisons between other surgical techniques, and recent advances were summarized.ResultsClinical studies show that UKA has many advantages, such as less trauma, faster recovery, and fewer postoperative complications. At present, the operative indication has been expanded. The body mass index more than 25 kg/m2, less than 60 years old, patellofemoral arthritis, and anterior cruciate ligament dysfunction are no longer considered as contraindications. The prosthesis type in UKA should be selected according to the patient’s condition. In recent years, the robot-assisted UKA can effectively improve the effectiveness, improve patient satisfaction, and reduce postoperative complications.ConclusionWith the development of surgical techniques, designs of prosthesis, and the robotic technology, UKA would be further applicated. As more long-term data on UKA become available, it will further guide clinicians in counseling patients on whether UKA should be performed.
ObjectiveTo systematically review the clinical risk factors, mechanisms, diagnostic strategies, and therapeutic advances in spontaneous rupture of hepatocellular carcinoma (SR-HCC), aiming to optimize clinical decision-making. MethodA comprehensive analysis of recent literature on SR-HCC was conducted to summarize the latest advancements in its epidemiological characteristics, risk factors, underlying mechanisms, diagnostic approaches, and treatment modalities. ResultsRisk factors for SR-HCC included tumor diameter >5 cm, exophytic tumor growth, moderate-to-massive ascites, elevated alpha-fetoprotein level, portal vein invasion, and chronic liver disease. The pathogenesis involved the following aspects. ① Tumor-specific growth dynamics: rapid proliferation causing tissue destruction, vascular compression, and intratumoral ischemia-necrosis. ② Tumor microenvironment alterations: chronic inflammation, thin-walled neovessels, hypoxia-induced matrix degradation increased the risk of SR-HCC. ③ Vascular injury: elastin degeneration, collagen degradation, and deposition of immune complexes led to increased vascular fragility. ④ Background of underlying liver diseases: cirrhosis-related hemodynamic instability and tissue fragility caused rupture. Diagnosis relied on clinical manifestations (acute abdominal pain, shock, intraperitoneal hemorrhage) and imaging. Contrast-enhanced CT showed 100% accuracy for active bleeding detection, ultrasound aided screening, and MRI was used for stable patients. Treatment strategies encompassed conservative therapy, interventional procedures (hemostasis success rate: 53%–100%, preferred for hemodynamically unstable cases but risk hepatic failure in patients with MELD ≥13 points), emergency surgery (high mortality: 16.5%–100%), staged resection (transcatheter arterial embolization followed by elective surgery with 45% of 5-year survival rate vs. 12-month median survival for conservative therapy), and radiofrequency ablation (limited evidence for hemostasis, safety/efficacy required further validation). Conclusions SR-HCC is a life-threatening complication influenced by multifactorial risks and complex molecular mechanisms. Early identification of high-risk patients, combined interventional and staged surgical approaches, and personalized treatment are critical for improving outcomes. Future research should focus on elucidating molecular pathways and refining risk assessment models and integrated therapeutic strategies.
ObjectiveTo summarize the research progress of ultrasmall superparamagnetic iron oxide (USPIO) enhanced magnetic resonance imaging (MRI) in normal-sized lymph node metastasis of colorectal cancer.MethodThe relevant literatures published recently at domestic and abroad about USPIO enhanced MRI in normal-sized lymph node metastasis of colorectal cancer were collected and reviewed.ResultsUSPIO, a kind of lymph node targeted magnetic resonance contrast agent, could be used to evaluate lymph node metastasis of malignant tumors. USPIO enhanced MRI could detect normal-sized lymph node metastasis in colorectal cancer effectively compared with normal MRI. It provided a higher diagnostic performance than normal enhanced MRI. In addition, USPIO enhanced MRI could also distinguish inflammatory and metastatic lymph nodes better that were difficult to be distinguished by normal enhanced MRI.ConclusionUSPIO enhanced MRI shows a certain potential for clinical application in detecting normal-sized lymph node metastasis of colorectal cancer, but it has not been widely used in China.
