BACKGROUND:The femorofibular angle is a commonly used reference angle for mechanical axis correction in high tibial osteotomy on a single plane,but there has been no in-depth study on the application of this angle in high tibial osteotomy on a single plane.OBJECTIVE:To explore the application effect of the femorofibular angle as a reference for mechanical axis correction in high tibial osteotomy on a single plane.METHODS:A retrospective analysis was conducted on 64 cases of knee osteoarthritis patients who underwent high tibial osteotomy on a single plane at Third Affiliated Hospital of Beijing University of Chinese Medicine from January 2023 to January 2024.The patients were grouped according to the intraoperative mechanical axis correction reference method.The observation group consisted of 32 cases,which used the femorofibular angle as a reference for mechanical axis correction during surgery.The control group consisted of 32 cases,which used electrocautery line measurement as a reference for mechanical axis correction during surgery.Both groups received the same perioperative treatment and management.The lower limb mechanical axis ratio,hip-knee-ankle angle,proximal medial tibial angle,and femorofibular angle were recorded before and after surgery to assess changes in the lower limb mechanical state.The operation time and number of fluoroscopies were recorded.The visual analog scale score and Lysholm score for pain and knee function were recorded before surgery and at 1 and 3 months after surgery to evaluate changes in knee pain and function.RESULTS AND CONCLUSION:(1)All patients completed the treatment and follow-up,and no serious adverse events occurred.(2)Before surgery,there was no statistically significant difference in the lower limb mechanical axis ratio,proximal medial tibial angle,hip-knee-ankle angle,and femorofibular angle between the two groups(P＞0.05).At 3 months after surgery,the lower limb mechanical axis ratio,proximal medial tibial angle,hip-knee-ankle angle,and femorofibular angle were significantly improved in both groups compared to before surgery,with statistically significant differences(P＜0.05).There was no significant difference between the two groups(P＞0.05).(3)During surgery,the operation time and number of fluoroscopies in the observation group were less than those in the control group,with statistically significant differences(P＜0.05).(4)At each follow-up point before and after surgery,there was no statistically significant difference in the visual analog scale score and Lysholm score between the two groups(P＞0.05).With the passage of time after surgery,the visual analog scale score and Lysholm score in both groups were significantly improved compared to before surgery(P＜0.05).(5)It is suggested that the application of the femorofibular angle as a reference for mechanical axis correction in high tibial osteotomy on a single plane can accurately locate the range of lower limb mechanical axis correction,is simple and reliable,and reduces the number of fluoroscopies and operation time compared to traditional electrocautery line measurement.

Objective:To explore the disease characteristics and TCM constitutions of patients with nonunion; To analyze the risk factors of nonunion and its correlation with TCM constitution; To provide research ideas for the prevention and treatment of nonunion with TCM based on the concept of "prevention of disease".Methods:This study was an observational case-control study. 334 orthopedic patients who visited the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September 2020 to September 2022 were selected. 167 patients were collected according to the diagnostic criteria of nonunion, then 167 patients who met the criteria of fracture healing were included as the control group. General information and the classification of TCM constitutions of the patients were collected. The distribution rules of TCM constitution and patients' risk factors were statistically analyzed, and the correlation between the two was explored.Results:The unbalanced constitution was found in 126 cases (75.45%) in the bone nonunion group and 108 cases (62.87%) in the fracture healing group, with statistical significance ( χ2=4.63, P=0.032). The proportion of TCM constitutional types distributed among the patients with nonunion were in the following order: phlegm-dampness constitution, yang-deficiency constitution, mild constitution, qi-deficiency constitution, yin-deficiency constitution, damp-heat constitution, qi-stagnation constitution, blood-stasis constitution and inherited-special constitution. There was statistical significance between the nonunion group and the fracture healing group in the phlegm-dampness and yang-deficiency in men and yang-deficiency in women ( χ 2 values were 19.12, 4.96, 4.92, respectively, P<0.01 or P<0.05). Diabetes [ OR (95% CI): 2.672(1.067, 6.693), P=0.036], BMI≥24 [ OR (95% CI): 1.903 (1.182,3.063), P=0. 008], phlegm-dampness [ OR (95% CI): 3.099 (1.624,5.913), P=0.001] and yang-deficiency [ OR (95% CI): 2.424 (1.252,4.693), P=0.009] as independent risk factors for the development of nonunion in multifactorial logistic regression analysis. Conclusions:The proportion of unbalanced constitution in patients with nonunion is significantly higher than that in patients with fracture healing. Phlegm-dampness constitution and yang-deficiency constitution are independent risk factors for the development of nonunion. TCM constitutional types can be an important factor in the risk assessment of nonunion and the prevention and treatment of nonunion based on the concept of "prevention of disease" has a sound theoretical basis and wide application prospects.

ObjectiveTo compare the short-term effectiveness of the three different manipulations for atlantoaxial joint disorders and their effects on surface electromyography of sternocleidomastoid muscle. MethodsNinty patients with atlantoaxial joint disorders were randomly divided into the tendon relaxing manipulation group， the tendon relaxing plus rehabilitation manipulation group， and the conventional manipulation group， with 30 cases in each group， and each group of patients received the corresponding manipulation treatment for 2 weeks.

Aconitum kusnezoffi leaves and their extracts were analyzed and evaluated by fourier transform infrared spectroscopy, second derivative spectra, and two dimensional correlation infrared spectroscopy in this research. There was characteristic IR absorption peaks of polyose (767 cm(-1)) in the Aconitum kusnezoffii leaves. The IR spectra of the aether extract were similar with the ethanol extract of Aconitum kusnezoffi leaves. The strong absorption peaks of carbonyl (1 715 cm(-1)) and saturated alkyl groups (2 921, 2 851 cm(-1)) could be detected. Some fatty acids were also detected in the water extract. Infrared spectroscopy, combined with two dimensional correlation infrared spectroscopy, can provide much structural information for herbs, which will benefit the quality control, components tracing and identification of extraction process of herbs roundly and qualitatively.

OBJECTIVETo evaluate the efficacy and feasibility of the Chinese drugs for supplementing Qi and activating blood circulation in preventing DVT after big operations in orthopaedics and traumatology and observe the change of D-dimer before and after treatment.

METHODSeventy patients ranging in age from 39 to 94 years who were treated by big operations in orthopaedics and traumatology were divided into two groups randomly. Traditional Chinese medinine (TCM) group (group A) and western medicine group (group B). On the 2rd day after operation d-dimer was tested from both groups and the patients in group A were given one dose of TCM every day and the patients in group B were subcutaneously injected low-molecular-weight heparins calcium (LMWH). On the 8th after operation d-dimer was tested again from both groups. The parameters, such as the incidence of DVT and pulmonary thromboembolism, bleeding condition, were evaluated respectively.

RESULTThe D-dimer decreased in group A and had significant difference (P < 0.05), group B had no significant difference, there was also no significant difference between two groups. DVT was found in 1 patient in group B (1/35). Petechiae were found in 10 patients in group A (10/35) and in 26 patients in group A (26/35), which had significant difference (P < 0.05).

CONCLUSIONBoth the Chinese drugs and anti-coagulation drug can prevent the incidence of DVT effectively, and Chinese herbs are feasible in the prevention of DVT.
