Objective:To investigate whether deltoid ligament (DL) injury produces axial-plane rotational instability of the ankle in patients with chronic ankle instability (CAI).Methods:A retrospective study was conducted to analyze the 33 patients with CAI who had been treated at Department of Orthopaedics, The First Affiliated Hospital of Nanjing Medical University between January 2023 and December 2024. The cohort consisted of 17 males and 16 females with an age of (31.5±9.9) years. The patients were assigned into 2 groups based on the presence of DL injury: a lateral chronic ankle instability (LCAI) group ( n=17) and a rotational ankle instability (RAI) group ( n=16). Barefoot natural walking trials were performed in all patients. Three-dimensional kinematic data were synchronously collected using an optical motion capture system (12 cameras) and force plates. A lower extremity model was constructed to obtain shank axial rotation (internal/external rotation) and rear-foot inversion/eversion angles. Continuous relative phase (CRP) analysis was employed to assess shank-rearfoot movement coupling. The mean absolute relative phase (MARP) and deviation phase (DP) were calculated. Results:There was no statistically significant difference in the clinical baseline data between the 2 groups, indicating comparability ( P>0.05). Throughout the gait cycle, no significant differences were found in shank rotation angles or rear-foot eversion angles between the RAI group and the LCAI group. However, CRP analysis revealed that during the early stance phase (initial contact and loading response), shank-rearfoot coupling was significantly lower in the RAI group than in the LCAI group. In the early stance phase, the CRP values in the RAI group were significantly higher than those in the LCAI group. The CRP curve changes in the RAI group were consistently higher in the standce phase of the entire gait cycle than those in the LCAI group, and the peak value of the CRP curve was larger in the RAI group. Concurrently, the RAI group exhibited significantly higher MARP and DP values than the LCAI group (27.48°±14.54° versus 15.21°±9.56°; 26.02°±11.73° versus 17.83°±9.82°) (both P<0.05). Conclusion:DL injury significantly damages the axial rotational stability of the ankle joint and significantly exacerbates the mechanical instability of the ankle joint in CAI patients.

Objective Based on the PDCA cycle theory,it explores the application mode of scenario simulation teaching method in clinical basic skills training.Methods The 96 students majoring in clinical medicine from the First Af-filiated Hospital of Harbin Medical University in 2019 were selected as the research objects,and the experimental group and the control group were set up respectively,with 48 students in each group,and skills training was car-ried out from March to December 2022.The control group was trained in the traditional way,and the experimental group was trained in the scenario simulation teaching method based on the PDCA cycle.The training effect and training satisfaction of the control group and the experimental group were compared and analyzed.Results In the sur-vey of the training effect of the students in the experimental group,the evaluation results of the basic clinical skills operation were higher than those in the control group,and the difference between the two groups was statistically significant(P＜0.01).In terms of the appropriate and safe operation mode,There was no significant difference be-tween the two groups(P＞0.05).In the training satisfaction survey,students in the experimental group were signifi-cantly more satisfied with the training than those students who are in the control group.The difference was statistical-ly significant(P＜0.01).Conclusion The application of scenario simulation teaching method based on PDCA cycle in clinical basic skills training helps to improve the quality of clinical basic skills training and student satisfaction.
