To analyze the disease burden of acute lymphoid leukemia(ALL) and its changing trends in China and globally from 1990 to 2021, aiming to provide a theoretical basis for disease prevention, treatment, and policy formulation.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

OBJECTIVE: To investigate the effectiveness of the suture anchor technique without knots for reconstruction of the anterior talofibular ligament (ATFL) combined with the reinforcement of the inferior extensor retinaculum in treating chronic lateral ankle instability (CLAI). METHODS: The clinical data of 31 patients with CLAI who were admitted between August 2017 and December 2023 and met the selection criteria were retrospectively analyzed. There were 18 males and 13 females, with an age range from 20 to 48 years (mean, 34.6 years). All patients had a history of repeated ankle sprain, with a disease duration of 6-18 months (mean, 9.65 months). The anterior drawer test and inversion stress test were positive, and tenderness was present in the ligament area. Stress X-ray films of the ankle joint showed a talar tilt angle of (10.00±2.78)° and an anterior talar displacement of (9.48±1.96) mm on the affected side. MRI revealed discontinuity, tortuosity, or disappearance of the ATFL structure. Preoperatively, the visual analogue scale (VAS) score was 5.2±2.1, and the American Orthopaedic Foot and Ankle Society (AOFAS) score was 62.9±7.1. All patients underwent arthroscopic debridement of the ankle joint followed by reconstruction of the ATFL using the suture anchor technique without knots combined with reinforcement of the inferior extensor retinaculum. Postoperatively, pain and function were assessed using the VAS and AOFAS scores. Stress X-ray films were taken to measure the talar tilt angle and anterior talar displacement to evaluate changes in ankle joint stability. Patient satisfaction was assessed according to the Insall criteria. RESULTS: All 31 surgeries were successfully completed. One case had wound exudation, while the remaining surgical incisions healed by first intention. Two cases experienced numbness on the lateral aspect of the foot, which disappeared within 1 month after operation. All patients were followed up 15-84 months (mean, 47.2 months). No complication such as anchor loosening, recurrent lateral ankle instability, superficial peroneal nerve injury, rejection reaction, or wound infection occurred postoperatively. The anterior drawer test and inversion stress test were negative at 3 months after operation. Stress X-ray films taken at 3 months after operation showed the talar tilt angle of (2.86±1.72)° and the anterior talar displacement of (2.97±1.32) mm, both of which were significantly different from the preoperative values ( t=12.218, P<0.001; t=15.367, P<0.001). At last follow-up, 2 patients had ankle swelling after exercise, which resolved spontaneously with rest; all 31 patients returned to their pre-injury level of sports or had no significant discomfort in daily activities. At last follow-up, 25 patients were pain-free, 4 had mild pain after exercise, and 2 had mild pain after walking more than 2 000 meters. The VAS score was 0.8±0.9 and the AOFAS score was 91.6±4.1, both of which were significantly different from the preoperative scores ( t=10.851, P<0.001; t=-19.514, P<0.001). According to the Insall criteria, 24 patients were rated as excellent, 4 as good, and 3 as fair, with a satisfaction rate of 90.3%. CONCLUSION The suture anchor technique without knots for reconstruction of the ATFL combined with reinforcement of the inferior extensor retinaculum provides satisfactory short- and mid-term effectiveness in treating CLAI.

Objective:To compare the clinical efficacy of the reamer-irrigator-aspirator (RIA) technique and iliac crest bone grafting (ICBG) in the treatment of adult noninfectious long bone nonunion of the lower extremity, and to evaluate the safety and effectiveness of the RIA technique.Methods:A retrospective review was conducted of 42 adult patients with noninfectious long bone nonunion of the lower extremity treated surgically at Zhengzhou Orthopaedic Hospital from January 2021 to June 2024. The cohort included 33 men and 9 women with a mean age of 47.0±14.4 years (range, 18-62 years). Twenty-three patients had nonunion on the left side and 19 on the right. Initial surgical fixation methods included plate fixation (19 cases), intramedullary nail (16 cases), external fixator (5 cases), and combined plate-and-nail fixation (2 cases). Revision procedures included debridement and freshening of the nonunion ends, revision or adjustment of internal fixation, and autologous bone grafting. Nineteen patients underwent graft harvesting with the RIA technique (RIA group), and 23 received autograft harvested from the iliac crest (iliac group). Baseline and perioperative variables compared between the two groups included sex, age, body-mass index, preoperative comorbidities, anatomical site of the nonunion (tibial or femoral), duration from the index fracture operation to the current revision, operative time, intraoperative blood loss, volume of blood transfusion and rate of perioperative complications, nonunion fracture sites, visual analogue scale (VAS) pain score at the fracture site, donor-site morphology and functional appearance scores, and radiographic union score for tibial fractures (RUST).Results:There was no significant difference in age between the RIA and ICBG groups (45.1±14.1 vs. 48.5±14.7 years, t=0.746, P=0.449). However, intraoperative blood loss was higher in the RIA group [300 (150, 720) ml, Z=-3.072, P=0.002] and the transfusion rate was higher (14/19 vs. 8/23, χ 2=6.313, P=0.012). The harvested bone volume was very similar [40(35, 60) cm 2vs. 40(35, 40) cm 2, Z=-1.077, P=0.281]. All patients were followed for a mean of 16.5±2.8 months (range, 7-40 months). VAS scores at the surgical site showed no significant difference between groups at 3 months (3.2±1.0 vs. 3.3±1.4, t= 4.754, P=0.720) and 6 months (1.6±0.8 vs. 1.8±1.2, t=6.841, P=0.542). Donor-site morphology and functional scores were significantly better in the RIA group at 3 months [14.5(13.0, 15.5) vs. 9.0(7.0, 10.0), Z=-3.748, P<0.001] and 6 months [15.5(15.0, 16.0) vs. 11.0(10.0, 13.0), Z=-3.782, P<0.001]. At 12 months postoperatively, RUST scores did not differ significantly between groups (10.6±1.2 vs. 10.4±1.5, t=0.483, P=0.632). The incidence of perioperative complications was comparable [42%(8/19) vs. 30%(7/23), χ 2=0.617, P=0.432]. Conclusions:Both RIA and ICBG achieved favorable clinical outcomes in the treatment of adult noninfectious lower-extremity long bone nonunion. Although RIA was associated with greater intraoperative blood loss, it resulted in less donor-site morbidity and better cosmetic and functional outcomes. Bone healing capacity and overall complication rates did not differ significantly between the two groups. These findings suggest that the RIA technique is safe and effective for use in the Chinese patient population.

Objective:To evaluate the application of the reaming-irrigation-aspirator (RIA) technique in autologous bone grafting for non-union of lower limb fracture.Methods:A retrospective analysis was conducted of the data of 16 patients with non-union of lower limb fracture who had undergone autologous bone grafting using the RIA technique at Department of Lower Limb Orthopaedics Ⅰ, Zhengzhou Orthopaedic Hospital from July 2023 to March 2024. There were 12 males and 4 females with an age of (47.2±14.3) years. Sites of non-union: the femur in 14 cases and the tibia in 2 cases. Initial surgical fixation: intramedullary nail fixation in 5 cases, plate fixation in 10 cases, and intramedullary nail plus plate fixation in 1 case. The time for fracture non-union was (21.0±12.0) months. Intraoperatively, autologous bone reaming was conducted using a drill bit of RIA system, and simultaneous flushing using irrigation fluid. The bone debris carried out by the irrigation fluid was collected into a filtration device through negative pressure aspiration. After the filter was opened to squeeze out congestion, bone paste was taken out for standby. Internal fixation methods were adjusted according to the non-union condition of the fractures. Finally, the bone paste was implanted into bone defects. The time for autologous bone harvest, amount of bone harvested, intraoperative blood loss, postoperative pain at a donor site, fracture healing, functional recovery of a lower limb and occurrence of complications were recorded.Results:In 2 of the 16 patients, fracture of the RIA drill bit occurred when bone marrow was harvested from the tibia, and their operation was completed only after the drill bits were replaced. In the 16 patients, time for bone harvest was (31.4±6.1) min, bone harvest volume (42.6±9.5) mL, and intraoperative blood loss (815.6±238.6) mL. The incisions in this cohort healed primarily after operation, and 4-week follow-up revealed that no patients had pain symptoms at a donor site. The 16 patients were followed up for (8.0±2.0) months after operation. All patients achieved bone union after (4.4±0.5) months. Follow-ups showed that no patients had complications like delayed infection, donor site fracture, or loosening or fracture of an internal fixator. According to the rating scale for lower limb function at the last follow-up, the function of affected limb was evaluated as excellent in 7 cases, as good in 8 cases, and as fair in 1 case.Conclusion:Application of RIA technique for autologous bone grafting to treat non-union of lower limb fracture can lead to fine fracture healing and good lower limb function, but no long-term pain symptoms in the donor area for the patients.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Objective:To retrospectively analyze the short-term curative effects of various treatment methods for displaced femoral neck fractures in young and healthy elderly individuals aged 65 to 74 years, while also exploring the surgical treatment options available for this population.Methods:A retrospective analysis was conducted on 159 patients with displaced femoral neck fractures(Garden types Ⅲ and Ⅳ)who were treated at Zhengzhou Orthopedic Hospital from July 2019 to June 2021.Among these patients, 75 were male and 84 were female, with ages ranging from 65 to 74 years, and an average age of 69.1±2.9 years.Patients were categorized based on the treatment method received: the total hip arthroplasty(THA)group comprised 77 cases, the hemiarthroplasty(HA)group included 42 cases, and the internal fixation(IF)group contained 40 cases.We compared intraoperative blood loss, operation time, Harris hip joint function scores one-year post-operation, and the incidence of secondary surgeries across the groups.Results:All 159 patients were followed up for a duration of 36 to 60 months(mean 45.1 months)postoperatively.Intraoperative blood loss was recorded as follows: IF group(19.3±7.0 ml), HA group(303.7±33.8 ml, P<0.001), and THA group(453.6±75.6 ml), with statistically significant differences in pairwise comparisons among the three groups(all P<0.001).The operation times were: IF group(40.7±13.1 min), HA group(53.2±7.5 min), and THA group(96.8±23.6 min), again showing statistically significant differences between each pair of groups(all P<0.001).The Harris hip score at one year postoperatively was(82.1±8.0)points, with an excellent and good rate of 82.4%.Specifically, the THA group scored(82.1±8.1)points with an excellent and good rate of 83.1%; the HA group scored(82.3±7.5)points with an excellent and good rate of 83.3%; and the IF group scored(81.8±8.0)points with an excellent and good rate of 80.0%.No statistically significant differences were observed in the excellent and good rates among the three groups(all P>0.05).A chi-square test performed on the overall postoperative complications among the three groups revealed no statistically significant differences( P=0.115). Conclusions:For relatively healthy elderly patients aged 65 to 74 with femoral neck fractures, hip replacement is not the sole treatment option.Treatment plans should be individualized based on patients' health conditions, transcending age limitations, to effectively address the growing challenges posed by femoral neck fractures in an aging society.

Objective:To investigate the risk factors and their predictive efficacy for early postoperative infection in elderly patients with intertrochanteric femur fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 286 elderly patients with intertrochanteric femur fracture admitted to Zhengzhou Orthopedic Hospital between August 2021 and August 2024, including 154 males and 132 females, aged 60-80 years [(72.5±5.8)years]. Fracture involved the left side in 148 patients and the right side in 138 patients. Internal fixation was performed on 214 patients and joint replacement on 72. Based on the occurrence of infection within two weeks postoperatively, the patients were divided into infection group ( n=25) and non-infection group ( n=261). Data were collected from the two groups, including basic information [gender, age, body mass index (BMI), cause of injury, fracture side], admission data (fasting blood glucose, diastolic blood pressure, systolic blood pressure), preoperative data [American Society of Anesthesiologists (ASA) classification, AO classification, serum C-reactive protein (CRP), serum albumin (Alb), serum CRP/Alb ratio, time from injury to surgery], and treatment-related information (surgical type, duration of surgery, intraoperative blood loss, quality of intraoperative reduction, postoperative antibiotic use). Univariate analysis and multivariate Logistic stepwise regression analysis were used to identify independent risk factors for early postoperative infection in elderly patients with intertrochanteric femur fracture. The receiver operating characteristic (ROC) curve was plotted and the area under the curve (AUC) was calculated to evaluate the predictive efficacy of each factor. Results:Univariate analysis showed significant differences between the two groups in fasting blood glucose on admission, preoperative serum CRP, preoperative serum Alb, preoperative serum CRP/Alb ratio, and duration of surgery ( P<0.01). There were no significant differences between the two groups in the remaining variables ( P>0.05). Multivariate Logistic stepwise regression analysis indicated that fasting blood glucose on admission ( OR=2.65, 95% CI 1.32, 5.32, P<0.01), preoperative serum CRP ( OR=1.10, 95% CI 1.04, 1.18, P<0.01), preoperative serum Alb ( OR=0.79, 95% CI 0.70, 0.90, P<0.01), preoperative serum CRP/Alb ( OR=143.78, 95% CI 4.46, 46.77, P<0.01), and duration of surgery ( OR=1.07, 95% CI 1.02, 1.11, P<0.01) were significantly associated with early postoperative infection in elderly patients with intertrochanteric femur fracture. ROC curve analysis showed that the sensitivity and specificity of preoperative serum CRP/Alb in predicting early postoperative infection in elderly patients with intertrochanteric femur fracture were 88.00% and 88.10%, and that the AUC of preoperative serum CRP/Alb prediction was 0.92, significantly greater than the AUC predicted separately by fasting blood glucose at admission, preoperative serum CRP, preoperative serum Alb and duration of surgery (0.76, 0.75, 0.77, 0.76, respectively). The optimal cut-off value for the preoperative serum CRP/Alb ratio was 1.78. Conclusions:Fasting blood glucose on admission, preoperative serum CRP, Alb, CRP/Alb ratio, and duration of surgery are independent risk factors for early postoperative infection in elderly patients with intertrochanteric femur fracture. These factors all possess certain predictive value for early postoperative infection, but the preoperative serum CRP/Alb ratio demonstrates the best predictive efficacy.
