Objective:To analyze research trends, hotspots, and international collaboration in temporomandibular disorders (TMD) from 2010 to 2024 using bibliometric methods.Methods:A total of 4 368 articles published between January 2010 to December 2024 were retrieved from PubMed using the search strategy temporomandibular disorders[MeSH Terms] OR temporomandibular joint disorders[Title/Abstract]. The R package"bibliometrix" was employed to analyze publication statistics, author collaboration networks, and keyword co-occurrence.Results:The annual publication volume in the TMD field increased 3.4-fold from 2010 to 2024, with an average annual output of 291.2 articles. MANFREDINI DANIELE was identified as the most prolific author (74 articles). The Journal of Oral Rehabilitation ranked first in terms of publication quantity (454 articles). The University of S?o Paulo (Brazil) emerged as the leading contributor, followed by Sichuan University (China) globally. Research hotspots predominantly focused on the DC/TMD diagnostic criteria and pain mechanisms. Analysis of international collaboration networks revealed that core authors (e.g., Lobbezoo F, Manfredini D) have driven advancements in the field through multidisciplinary collaboration (dentistry+psychology+medical imaging). The high-frequency occurrence of the imaging keyword "magnetic resonance imaging (MRI)" underscores its pivotal role in diagnosing disc displacement. Chinese institutions (Sichuan University, Peking University) ranked second globally in research output; however, interdisciplinary international collaboration remained limited, with multiple-country publications (MCP) accounting for only 13.0%. Conclusions:TMD research demonstrates interdisciplinary integration, highlighting the need for future emphasis on Asian population studies and innovative diagnostic/therapeutic technologies.

Objective:To evaluate the diagnostic performance of the Vesical Imaging-Reporting and Data System（VI-RADS）based on multiparametric magnetic resonance imaging（mp-MRI）for muscle-invasive bladder cancer（MIBC）.Methods:A systematic search was conducted in PubMed，Web of Science，and Embase databases for studies published between September 2018 and December 2023 that investigated the use of VI-RADS for diagnosing MIBC. Inclusion criteria were studies utilizing mp-MRI-based VI-RADS scoring to determine MIBC. Exclusion criteria were studies with fewer than 10 patients，overlapping study populations，or those failing to assess the diagnostic performance of VI-RADS for MIBC. After quality assessment，RevMan 5.4 and Stata 15.1 were used to calculate pooled sensitivity and specificity，generate forest plots and summary receiver operating characteristic（SROC）curves，and determine the area under the curve（AUC）. Publication bias was assessed using Deeks funnel plot. Heterogeneity was evaluated using the I2 statistic，with meta-regression and subgroup analyses to explore its sources. Results:Twenty-nine studies involving 3 577 patients were included. At a VI-RADS cutoff of 3，the pooled sensitivity and specificity for MIBC diagnosis were 93%（95%CI 0.90-0.95）and 82%（95%CI 0.76-0.88），respectively. At a cutoff of 4，these values were 83%（95%CI 0.78-0.87）and 93%（95%CI 0.90-0.95）. The hierarchical SROC（HSROC）AUCs were 0.95 and 0.94 for cutoffs of 3 and 4，respectively. Subgroup and meta-regression analyses revealed that at a cutoff of 3，patient sample size，study design，MRI field strength，number of radiologists，surgical approach，and DWI/DCE imaging planes contributed to sensitivity heterogeneity（ P < 0.05）. All factors except study design and DWI plane were sources of specificity heterogeneity（ P < 0.05）. At a cutoff of 4，all factors significantly influenced heterogeneity in both sensitivity and specificity（ P < 0.05）. Meta-regression confirmed that both cutoffs（3 and 4）were significant sources of heterogeneity（ P < 0.05）. Conclusions:VI-RADS demonstrates excellent diagnostic performance for MIBC at both cutoffs（3 and 4），with VI-RADS ≥ 3 showing superior sensitivity and VI-RADS ≥ 4 offering higher specificity. The cutoff of 3 provides better overall diagnostic efficacy.

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.

Objective:To analyze the clinical efficacy of arthroscopic transverse release of the iliotibial band through peritrochanteric space for the treatment of external snapping hip.Methods:A total of 30 patients (12 males and 18 females) with bilateral external snapping hip underwent arthroscopic transverse release of the iliotibial band through peritrochanteric space in Department of Sports Medicine, Senior Department of Orthopaedics, the Fourth Medical Center, Chinese PLA General Hospital were retrospectively analyzed from May 2021 and June 2022. The average age was 32.5±8.2 years (range, 17-51 years). At the same time, 30 patients who underwent arthroscopic external release of the iliotibial band through the external surface of the iliotibial band (external iliotibial band group) were selected as control group, including 13 males and 17 females, aged 29.5±6.8 years (range, 11-45 years). The visual analogue scale (VAS), modified Harris hip score (mHHS), and gluteal muscle contracture disability scale (GDS) were compared between the two groups at preoperative, 6 months postoperative, and final follow-up.Results:All patients successfully completed the operation and were followed up for 17.5±3.3 months (range, 12-25 months). The VAS scores of the two groups at the last follow-up were lower than those before operation ( P<0.05). The mHHS scores before operation, 6 months after operation and at the last follow-up in the peritrochanteric space group were 76.5 (67.0, 85.5), 98.5 (94.8, 100.0) and 100.0 (97.0, 100.0), respectively, and those in the external iliotibial band group were 80.5 (70.0, 86.0), 100.0 (96.0, 100.0) and 100.0 (99.5, 100.0). The differences in mHHS scores between the two groups were statistically significant for intragroup comparisons ( P<0.05); of these, 6 months postoperatively and at the last follow-up were greater than preoperatively, with statistically significant differences ( P<0.05); the differences at 6 months postoperatively and at the last follow-up were not statistically significant ( P>0.05). There was no significant difference in mHHS scores between groups at different time points ( P>0.05). The GDS before operation, at 6 months after operation and at the last follow-up were 47.0 (35.8, 64.5), 90.0 (81.0, 94.0) and 93.5 (89.8, 98.0) in the peritrochanteric space group, and 51.0 (38.0, 64.5), 50.0 (81.0, 94.0) and 93.5 (89.8, 98.0) in the external iliotibial band group, respectively. The differences in GDS between the two groups were statistically significant for intragroup comparisons ( P< 0.05); of these, 6 months postoperatively and at the last follow-up were greater than preoperatively, with statistically significant differences ( P<0.05); the differences at 6 months postoperatively and at the last follow-up were not statistically significant ( P>0.05). There was no significant difference in GDS between groups at different time points ( P>0.05). Conclusion:Arthroscopic transverse release of the iliotibial band through peritrochanteric space for the treatment of external snapping hip can effectively reduce hip pain and improve hip function, with satisfactory clinical results, and can be used as an alternative treatment to transverse release through the external surface of the iliotibial band.

OBJECTIVE: To introduce a scout view scanning technique of back-forward bending CT (BFB-CT) in simulated surgical position for evaluating the remaining real angle and flexibility of thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture. METHODS: A total of 28 patients with thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture who met the selection criteria between June 2018 and December 2021 were included in the study. There were 6 males and 22 females with an average age of 69.5 years (range, 56-92 years). The injured vertebra were located at T ₁₀-L ₂, including 11 cases of single thoracic fracture, 11 cases of single lumbar fracture, and 6 cases of multiple thoracolumbar fractures. The disease duration ranged from 3 weeks to 36 months, with a median of 5 months. All patients received examinations of BFB-CT and standing lateral full-spine X-ray (SLFSX). The thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), local kyphosis of injured vertebra (LKIV), lumbar lordosis (LL), and the sagittal vertical axis (SVA) were measured. Referring to the calculation method of scoliosis flexibility, the kyphosis flexibility of thoracic, thoracolumbar, and injured vertebra were calculated respectively. The sagittal parameters measured by the two methods were compared, and the correlation of the parameters measured by the two methods was analyzed by Pearson correlation. RESULTS: Except LL ( P>0.05), TK, TLK, LKIV, and SVA measured by BFB-CT were significantly lower than those measured by SLFSX ( P<0.05). The flexibilities of thoracic, thoracolumbar, and injured vertebra were 34.1%±18.8%, 36.2%±13.8%, and 39.3%±18.6%, respectively. Correlation analysis showed that the sagittal parameters measured by the two methods were positively correlated ( P<0.001), and the correlation coefficients of TK, TLK, LKIV, and SVA were 0.900, 0.730, 0.700, and 0.680, respectively. CONCLUSION Thoracolumbar kyphosis secondary to old osteoporotic vertebral compression fracture shows an excellent flexibility and BFB-CT in simulated surgical position can obtain the remaining real angle which need to be corrected surgically.

OBJECTIVE: To investigate the changes in spinal-pelvic sagittal parameters from preoperative standing to prone position in old traumatic spinal fractures with kyphosis. METHODS: The clinical data of 36 patients admitted between December 2016 and June 2021 for surgical treatment of old traumatic spinal fractures with kyphosis, including 7 males and 29 females, aged from 50 to 79 years (mean, 63.9 years), were retrospectively analyzed. Lesion segments included 2 cases of T ₁₁, 12 cases of T ₁₂, 2 cases of T _{11, 12}, 4 cases of T ₁₂ and L ₁, 12 cases of L ₁, 2 cases of L ₂, 1 case of L _{2, 3}, and 1 case of L ₃. The disease duration ranged from 4 to 120 months, with an average of 19.6 months. Surgical procedures included Smith-Petersen osteotomy in 4 cases, Ponte osteotomy in 6 cases, pedicle subtraction osteotomy in 2 cases, and improved fourth level osteotomy in 18 cases; the remaining 6 cases were not osteotomized. The bone mineral density ranged from -3.0 to 0.5 T, with a mean of -1.62 T. The spinal-pelvic sagittal parameters from preoperative standing to prone positions were measured, including local kyphosis Cobb angle (LKCA), thoracic kyphosis (TK), lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT), and PI and LL mismatch (PI-LL). The kyphotic flexibility=(preoperative standing LKCA-preoperative prone LKCA)/preoperative standing LKCA×100%. Spinal-pelvic sagittal parameters were compared between standing position and prone position before operation, and Pearson correlation was used to judge the correlation between the parameters of standing position and prone position before operation. RESULTS: When the position changed from standing to prone, LKCA and TK decreased significantly ( P<0.05), while SS, LL, PT, and PI-LL had no significant difference ( P>0.05). Pearson correlation analysis showed that LL was significantly correlated with SS and PI-LL in both standing and prone positions ( P<0.05), and the correlation strength between LL and SS in prone position was higher than that in standing position. In the standing position, LKCA was significantly correlated with SS and PT ( P<0.05). However, when the position changed from standing to prone, the correlation between LKCA and SS and PT disappeared, while PT and PI-LL was positive correlation ( P<0.05). The kyphotic flexibility was 25.13%-78.79%, with an average of 33.85%. CONCLUSION For the patients of old traumatic spinal fractures with kyphosis, the preoperative LKCA and TK decrease significantly from standing position to prone position, and the correlation between spinal and pelvic parameters also changed, which should be taken into account in the formulation of preoperative surgical plan.
