Fracture delayed union or nonunion is a serious complication after fracture treatment, and both simple Western medicine and traditional Chinese medicine （TCM） treatments have obvious limitations. In recent years, the integrated TCM and Western medicine treatment for fracture delayed union or nonunion has shown a precise and diversified development trend, achieving breakthrough progress in treatment regimen optimization, mechanism of action, and new technology research and development. The treatment regimens are continuously optimized towards classification-based management and synergistic efficacy, and personalized intervention plans are formulated according to different types of fracture delayed union or nonunion. Among them, interventions combining TCM with Western medical fixation, biological agents, cell therapy, and other related technologies have significant curative effects, and can effectively accelerate callus growth and shorten fracture healing time. The research and development of new technologies focuses on the integration of cutting-edge TCM and Western medicine technologies, further enriching treatment options, improving treatment outcomes, and providing solid support for precise treatment. Based on relevant research results and meta-analysis conclusions, this article systematically reviewed the core progress of integrated TCM and Western medicine in the treatment of fracture delayed union or nonunion, highlighting its synergistic advantages, and providing a reference for clinical diagnosis and treatment.

Objective To explore the risk factors for hemodynamic instability （HI） after carotid endarterectomy （CEA） and its impact on prognosis. Methods Data from 363 patients who underwent CEA at Huashan Hospital, Fudan University between January 2015 and December 2020 were collected. Based on the occurrence of HI after CEA, the patients were divided into a control group （n=291） and an HI group （n=72）. Logistic regression models were used to analyze the risk factors for HI following CEA. Results Univariate analysis and multiple analysis showed that transient ischemic attack （TIA） was an independent risk factor for HI after CEA. Statistically significant differences （P<0.05） were observed between the two groups in terms of the incidence of short-term myocardial infarction, long-term all-cause mortality, cardio-cerebrovascular mortality, and blood pressure control. Conclusion TIA is an independent risk factor for HI after CEA. HI increases the incidence of myocardial infarction within 30 d after surgery, as well as cardio-cerebrovascular mortality and all-cause mortality within 5 years after surgery, making long-term blood pressure control more challenging.

Objective To compare the efficacy of percutaneous transforaminal endoscopic discectomy （PTED） versus traditional posterior laminotomy decompression in the treatment of lumbar disc herniation. Methods A total of 90 patients with lumbar disc herniation admitted to our hospital between January 2022 and January 2024 were selected and randomly divided into a control group and an observation group by random number table method. The control group （45 cases） underwent traditional posterior laminotomy decompression combined with nucleotomy, while the observation group （45 cases） received PTED combined with nucleotomy. The following parameters were compared between the two groups： surgical parameters （operation time, time of first postoperative ambulation, incision length, and intraoperative blood loss）, lumbar spine functional recovery [Oswestry Disability Index （ODI）, Japanese Orthopaedic Association （JOA） score, and Visual analog scale （VAS） score], serum markers [C-reactive protein （CRP）, interleukin-1β （IL-1β）, and matrix metalloproteinase-3 （MMP-3）], and complication rates. Results The observation group exhibited shorter operation time and first postoperative ambulation time compared to the control group, as well as lower intraoperative incision length and less blood loss （P<0.05）. No statistically significant differences in ODI, JOA, and VAS scores were observed between the groups before treatment （P>0.05）; 6 months after operation, compared to the control group, the observation group had lower ODI scores （with an improvement rate of over 90%）, higher JOA scores, and lower VAS scores （P<0.05）. No significant differences in CRP, IL-1β, and MMP-3 were noted between the groups preoperatively （P>0.05）; postoperatively, the observation group demonstrated lower levels of CRP, IL-1β, and MMP-3 than the control group （P<0.05）. The total complication rates were 22.22% and 6.67% in the control and observation groups, respectively （P<0.05）. Conclusion In the treatment of lumbar disc herniation, PTED combined with nucleotomy demonstrates superior clinical efficacy, effectively accelerating surgical and postoperative recovery process, improving lumbar function, and reducing inflammatory response and complication rates, which is worth clinical promoting.

Objective To evaluate the efficacy of a bioactive glass （BG） and polyetheretherketone （PEEK） interbody fusion cage in transforaminal lumbar interbody fusion （TLIF） procedures. Method A retrospective analysis was performed on 174 patients who underwent TLIF surgery for lumbar degenerative diseases from January 2017 to December 2023. Patients were categorized into an autogenous bone graft （ABG） group （99 cases） and a bioactive glass group （75 cases） based on the bone graft material used. Patient demographics, surgical details, follow-up details, fusion segment balance parameters, and fusion progression images were collected. Surgical duration, intraoperative blood loss, postoperative mobilization time, hospital stay, and Oswestry Disability Index （ODI） were compared between the two groups. Pre- and post-operative intervertebral space height and lordosis angle, as well as bone graft fusion outcomes were also compared between the two groups. Results No statistically significant differences （P>0.05） were observed between the two groups in terms of surgical time, blood loss, postoperative mobilization time, or hospital stay. Pre- and post-operative ODI scores did not differ significantly between the groups （P>0.05）; however, both groups demonstrated a statistically significant reduction in ODI scores 5 d postoperatively compared to preoperative levels （P<0.05）. Both groups exhibited significant improvements in anterior and posterior disc height compared to preoperative measurements （P<0.05）, with no statistically significant difference between the two groups （P>0.05）. The lordosis angle of the fused segment improved significantly postoperatively in both groups （P<0.05）, with no statistically significant difference between the groups （P>0.05）. Postoperative follow-up revealed no cases of bone graft failure or pseudarthrosis in either group. Conclusion The combination of a PEEK interbody fusion cage with bioactive glass bone graft in lumbar spine surgery demonstrates good efficacy, significantly restoring intervertebral space height and lordosis angle in the fused segment.

Objective To evaluate the clinical value of transumbilical gastric conduit formation in esophagectomy compared with conventional open abdominal approach. Methods We retrospectively analyzed 102 patients who underwent radical esophagectomy for esophageal cancer at our hospital between January 2024 and January 2025. According to different surgical approaches, the patients were divided into a transumbilical group and a conventional open approach group （51 patients in each group）. Operative parameters including surgical duration, intraoperative blood loss, lymph node yield, postoperative pain scores, postoperative recovery, and complication rates were compared between the two groups. Results The transumbilical group demonstrated significantly reduced intraoperative blood loss, lower postoperative pain scores, shorter time to first flatus, and reduced length of hospital stay compared to the conventional open approach group （P<0.05）. No significant difference was observed in the total number of harvested lymph nodes between the two groups （P>0.05）. The transumbilical group exhibited a significantly lower incidence of incision-related complications than the conventional open approach group （P<0.05）. There was no statistically significant difference in the incidence of other complications such as anastomotic leakage, pulmonary infection, and chylous leakage between the two groups （P>0.05）. Conclusion Compared with conventional open abdominal gastric conduit formation, the transumbilical approach offers significant advantages including reduced surgical trauma, accelerated postoperative recovery, and lower complication rates, without compromising lymph node dissection adequacy or increasing anastomotic complications. This approach represents a safe and effective option for esophagectomy.

Objective To explore the value of 3D laparoscopic gastric perforation repair surgery for patients with gastric ulcer complicated with gastric perforation.
