“…The investigators performed routine follow-up at 2 weeks, 1 month, 3 months, 6 months, and 12 months postoperatively through telephone interviews or outpatient reviews. The database has been used by numerous orthopedic researchers 33 – 40 , and the information is more accurate than in the administration databases due to manual collection and update.…”

Background: Malnutrition is significantly associated with unfavorable outcomes, but there is little high-level evidence to elucidate the association of malnutrition with losing walking independence (LWI) after hip fracture surgery. This study aimed to assess the association between preoperative nutritional status evaluated by the Controlling Nutritional Status (CONUT) score and walking independence at 180 days postoperatively in Chinese older hip fracture patients. Methods: This prospective cohort study included 1958 eligible cases from the SSIOS database. The restricted cubic spline was used to assess the dose-effect relationship between the CONUT score and the recovery of walking independence. Propensity score matching was performed to balance potential preoperative confounders, and multivariate logistic regression analysis was applied to assess the association between malnutrition and LWI with perioperative factors for further adjustment. Furthermore, inverse probability treatment weighting and sensitivity analyses were performed to test the robustness of the results and the Fine and Gray hazard model was applied to adjust the competing risk of death. Subgroup analyses were used to determine potential population heterogeneity. Results: The authors found a negative relationship between the preoperative CONUT score and recovery of walking independence at 180 days postoperatively, and that moderate-to-severe malnutrition evaluated by the CONUT score was independently associated with a 1.42-fold (95% CI, 1.12–1.80; P=0.004) increased risk of LWI. The results were overall robust. And in the Fine and Gray hazard model, the result was still statistically significant despite the apparent decrease in the risk estimate from 1.42 to 1.21. Furthermore, significant heterogeneities were observed in the subgroups of age, BMI, American Society of Anesthesiologists score, Charlson’s comorbidity index, and surgical delay (P for interaction < 0.05). Conclusion: Preoperative malnutrition is a significant risk factor for LWI after hip fracture surgery, and nutrition screening on admission would generate potential health benefits.

“…In our recent study of lower extremity specimens, the mechanisms of injury in two scenarios (falling from height and motor vehicle crash) were simulated and this type of fracture was successfully reproduced in 6/10 specimens. In both settings, the axial or anter‐posterior force from the femoral condyle was concentrated on the posterior half of the tibial plateau, resulting in an isolate shearing fracture with no depression 27,28 . In addition, we found that the clinical outcomes of previously treated patients with Hoffa‐like fractures of the tibial plateau were not satisfactory.…”

ObjectiveThe posterior coronal shearing fractures of the tibial plateau are rare and can be easily missed or ignored. Our team defined these fractures as Hoffa‐like fracture of the tibial plateau and conducted a series of studies. The aim of this study is to introduce the characteristics of the Hoffa‐like fracture of the tibial plateau, propose a new classification system and evaluate its validity.MethodsSixty‐one patients with Hoffa‐like fractures of the tibial plateau were treated in five trauma centers (I–III) from 2017 to 2020. A new classification system was developed based on the morphological fracture patterns in CT and radiographic of the first 30 cases. Ten cases of suspected tibial plateau Hoffa‐like fractures were supplemented additionally to the 61 cases to increase the accuracy. CT and radiographic images of the 71 cases were reviewed independently by four reviewers on two separate occasions and classified according to the new classification system. Cohen's kappa coefficient (κ) was used to analyze the reliability on separate observers at the same time and to analyze the classification made by same observer at different times (intra‐observer), which measures inter‐observer and intra‐observer agreements.ResultsOut of the 61 patients, 46 (75.4%) isolated coronal fractures involving the medial condyle of tibial plateaus and 53 (86.9%) combined with intercondylar spine fractures. The κ‐values were calculated for the new classification system (mean κ = 0.74 inter‐observer, mean κ = 0.79 intra‐observer, indicating substantial agreement).ConclusionThe novel classification lends insight into fracture morphology of the tibial plateau Hoffa‐like fractures, has good inter‐ and intra‐observer validity, and it aids in treatment.

He has conducted many large randomized trials in patients with TPF, contributing to the surgical treatment modality, classi cation, and prevention of postoperative related complications about TPF [12,13,14,15]. Professor Luo Congfeng is one of the top experts in the eld of traumatic orthopedics at the Sixth A liated Hospital of Shanghai Jiaotong University.…”

Background:Tibial plateau fracture (TPF) is a complex intraarticular fracture that has been extensively researched. However, there has been a lack of bibliometric studies investigating global research trends in TPF. This study aims to analyze the knowledge framework, research hotspots, and thematic trends in the field of TPF research. Methods: Scientific outputs related to TPF from 1994 to 2022 were retrieved from the Web of Science Core Collection. Three bibliometric tools, namely CiteSpace, VOSviewer, and an online analytical platform, were employed for the analysis. The main analyses encompassed contributions from countries, publication and citation counts, institutions, authors, funding agencies, and journals, as well as keyword clustering. Results: A total of 884 articles were identified, and the number of annual publications on TPF exhibited a generally upward trend. China emerged as the most prominent contributor with the highest number of publications, while the United States had the largest H-index. Hebei Medical University made the most significant investment in this field. Professors Zhang Yingze, Luo Congfeng, Egol Kenneth A, and Chen Wei emerged as core authors in this field. The most productive journal was Injury-International Journal of the Care of the Injured. The keywords were clustered into six groups: Epidemiology and prognosis, Internal fixation and complications, Surgical protocol and finite element analysis, Diagnosis and new techniques, Complex fracture types, and Bone graft. These clusters showed a trend of balanced and diversified development. The ongoing outbreak keywords included "debris," "classification," "trauma," "posterolateral fracture," and "risk factors," which were considered as future research hotspots deserving more attention. Conclusions:Surgical protocols and bone defect filling materials for complex types of TPF have received increasing attention from orthopedic surgeons. It is anticipated that these research topics will continue to be significant and hold a prominent position in the near future.
