Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To explore the advantages of minimally invasive internal fixation assisted by an orthopedic robot in the treatment of tibial plateau fractures of Schatzker types Ⅱ and Ⅲ that can be indirectly reduced.Methods:A retrospective study was conducted of the 18 patients who had been treated for tibial plateau fractures of Schatzker types Ⅱ and Ⅲ at Department of Orthopaedics, The Fourth Hospital of Wuhan from December 2019 to December 2021. They were 12 males and 6 females with an age of (45.2±9.6) years. All fractures were closed. Of them, 6 were complicated with an avulsion fracture at the insertion point of the anterior cruciate ligament, 1 with tear of the medial collateral ligament, and 8 with tear of the lateral meniscus. All patients were treated with minimally invasive internal fixation using the "fence" screw technique after indirect reduction assisted by an orthopedic surgical robot. Those combined with avulsion fracture of the anterior cruciate ligament and meniscus tear underwent one-stage arthroscopic surgery, while those combined with tear of the medial collateral ligament underwent one-stage open repair. The fracture reduction was evaluated according to the Rasmussen radiological scoring system, and the knee joint function evaluated using the American Hospital for Special Surgery (HSS) scoring system.Results:All the 18 patients were fully followed up for (10.6±1.9) months. The X-ray films immediately after surgery showed good fracture reduction. The fractures healed after (11.3±1.2) weeks. At 6 months after surgery, the Rasmussen knee score was (16.8±1.0) points, giving 5 excellent and 13 good cases; the HSS score was (93.2±3.0) points, giving 17 excellent and 1 good cases. By the last follow-up, no serious complications occurred, such as common peroneal nerve injury, popliteal vascular injury, postoperative infection, or internal fixation failure.Conclusion:Since minimally invasive internal fixation assisted by an orthopedic robot can lead to fine clinical efficacy for tibial plateau fractures of Schatzker types Ⅱ and Ⅲ, this technique can be widely applied in clinical practice.

Peritoneal metastasis is one of the common site of colorectal cancer metastasis and associated with a poor prognosis. The core strategy for colorectal cancer peritoneal metastasis primarily revolves around a comprehensive treatment approach with cytoreductive surgery and systemic chemotherapy as the mainstay, supplemented by intraperitoneal chemotherapy. As an important supplement to treatment, intraperitoneal chemotherapy has broad application prospects. The main modalities are hyperthermic intraperitoneal chemotherapy (HIPEC), neoadjuvant intraperitoneal and systemic chemotherapy (NIPS), early postoperative intraperitoneal chemotherapy (EPIC), sequential postoperative intraperitoneal chemotherapy (SPIC), normothermic intraperitoneal chemotherapy (NIPEC) and pressurized intraperitoneal aerosol chemotherapy (PIPAC). To promote the standardized application of intraperitoneal chemotherapy, further research on the mechanisms underlying peritoneal metastasis of colorectal cancer, selection of effective intraperitoneal chemotherapy agents, determination of optimal timing and administration protocols, exploration of the feasibility of sequential intraperitoneal chemotherapy and conduction of valuable basic and clinical research are currently needed. This paper will review the development and origins of intraperitoneal chemotherapy, treatment modalities, as well as the current application status and prospects of various treatment approaches in the context of peritoneal metastasis of colorectal cancer.

Objective To observe the clinical manifestations of 3 cases with myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease and anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis antibody overlapping syndrome (MNOS), aiming to expand the understanding of the clinical spectrum of such syndromes. Methods Retrospective analysis was performed on the data of 3 patients with MNOS who were positive for both MOG antibodies and NMDAR antibodies. Clinical features, neuroimaging characteristics, and outcomes were collected, and cell-based assay (CBA) technique was used for diagnosis. Results One case presented both positive MOG antibodies and NMDAR antibodies, but the clinical manifestations were typical symptoms of anti-NMDAR encephalitis. In one case, the clinical and cranial magnetic resonance imaging (MRI) features of demyelinating disease recurred after anti-NMDAR encephalitis, with atypical symptoms of MNOS such as numbness and weakness in limbs, blurred vision, and diplopia. The last case presented both positive MOG antibodies and NMDAR antibodies, but the clinical manifestations were typical symptoms of anti-NMDAR encephalitis. In MNOS, MOG antibody-associated disease and anti-NMDAR encephalitis may appear simultaneously or sequentially, with epilepsy being the most common symptom. Cranial MRI findings showed that the patients presented and mainly involved supratentorial lesions, which may also involve the brainstem, but no spinal cord lesions were found. All patients showed slightly abnormal cerebrospinal fluid. Patients showed a good response to first-line immunotherapy during the acute phase of the disease, with a favorable prognosis. But most patients were prone to relapse. Conclusion In MNOS patients, anti-NMDAR encephalitis may present with clinical and(or)MRI features of demyelinating disease simultaneously or sequentially. The clinical manifestations of patients are complex and diverse. Patients with atypical symptoms require to improving the understanding of MNOS and timely treatment.

OBJECTIVE: To investigate the prevalence of vitamin D deficiency and its association with blood eosinophil count in healthy population and patients with chronic obstructive pulmonary disease (COPD). METHODS: We analyzed the data of a total 6163 healthy individuals undergoing routine physical examination in our hospital between October, 2017 and December, 2021, who were divided according to their serum 25(OH)D level into severe vitamin D deficiency group (< 10 ng/mL), deficiency group (< 20 ng/mL), insufficient group (< 30 ng/mL) and normal group (≥30 ng/mL). We also retrospectively collected the data of 67 COPD patients admitted in our department from April and June, 2021, with 67 healthy individuals undergoing physical examination in the same period as the control group. Routine blood test results, body mass index (BMI) and other parameters were obtained from all the subjects, and logistic regression models were used to investigate the association between 25(OH)D levels and eosinophil count. RESULTS: The overall abnormal rate of 25(OH)D level (< 30 ng/mL) in the healthy individuals was 85.31%, and the rate was significantly higher in women (89.29%) than in men. Serum 25(OH)D levels in June, July, and August were significantly higher than those in December, January, and February. In the healthy individuals, blood eosinophil counts were the lowest in severe 25(OH)D deficiency group, followed by the deficiency group and insufficient group, and were the highest in the normal group (P < 0.05). Multivariable regression analysis showed that an older age, a higher BMI, and elevated vitamin D levels were all risk factors for elevated blood eosinophils in the healthy individuals. The patients with COPD had lower serum 25(OH)D levels than the healthy individuals (19.66±7.87 vs 26.39±9.28 ng/mL) and a significantly higher abnormal rate of serum 25(OH)D (91% vs 71%; P < 0.05). A reduced serum 25(OH)D level was a risk factor for COPD. Blood eosinophils, sex and BMI were not significantly correlated with serum 25(OH)D level in patients with COPD. CONCLUSION Vitamin D deficiency is common in both healthy individuals and COPD patients, and the correlations of vitamin D level with sex, BMI and blood eosinophils differ obviously between healthy individuals and COPD patients.

Objective:To explore the clinical efficacy of robot guided balloon tibial osteoplasty for the treatment of Schatzker II and III tibial plateau fractures.Methods:A retrospective analysis was conducted on the data of 59 patients admitted from January 2017 to December 2022. According to the surgical method, they were divided into two groups: robot guided percutaneous balloon tibial osteoplasty with "Jail" screw fixation group (study group) and open reduction and internal fixation group (control group). There were 28 cases in the study group, including 13 males and 15 females, with an average age of 44.21±9.70 years. In the study group, 8 cases were diagnosed of Schatzker II and 20 cases of Schatzker III. There were 31 cases in the control group, including 16 males and 15 females, with an average age 47.94±13.73 years. In the control group 7 cases were diagnosed of Schatzker II and 24 cases of Schatzker III. Between the two groups, demographics, surgical challenges and outcomes were all compared, including age, fracture classification, fracture collapse volume, surgical time, intraoperative bone graft volume, incision length, postoperative drainage volume, length of stay, fracture reduction quality (proportion of collapse area reduction volume evaluated by postoperative CT, Rasmussen radiology score), knee joint hospital for special surgery (HSS) score at 6 months after surgery, pain visual analogue scale (VAS) scores at before and 3 days after surgery and the final follow-up, complications.Results:All the patients were followed up for 116.92±6.08 months. The surgical time was 88.50±21.32 min in the study group, and 65.16±18.10 min in the control group with significant difference ( t=4.55, P<0.001). Between the study group and the control group, the intraoperative bone graft volume (3.04±1.15 cm 3vs. 5.87±2.03 cm 3), incision length (3.34±1.02 cm vs. 17.65±2.33 cm), postoperative drainage volume (13.04±19.45 ml vs. 85.16±41.54 ml), and length of hospital stay (11.64±3.07 d vs. 18.77±4.78 d) were all found to be significantly differently ( t=-6.69, P<0.001; t=-31.02, P<0.001; t=-8.67, P<0.001; t=-7.06, P<0.001). After 6 months of surgery, Rasmussen's radiological score was 17.32 ± 1.06 in the study group and 17.58 ± 0.85 in the control group with no significant difference ( t=-1.04, P=0.150). After 6 months of surgery, the HSS score in the study group was 93.75±2.22, and 92.71±2.19 in the control group with significant difference ( t=1.81, P=0.038). The VAS score between the study and control group was 7.04±0.92 vs. 7.00±0.97 before the surgery, 2.71±0.85 vs. 4.74±0.93 three days after surgery, and 0.21±0.49 vs. 0.26±0.51 at the final follow-up with significant pain relief at either three days or the final follow up within either group ( F=1884.53, P<0.001; F=55.98, P<0.001). Significant difference between the two groups was found at three days after the surgery ( t=-10.28, P<0.001), while no significant difference was found before surgery or at the final follow-up ( P>0.05). The wounds in the study group healed well, while in the control group, 4 cases had poor wound healing. One case in the study group had intraoperative balloon rupture and contrast agent leakage, while two cases had bone graft material leakage. There were no intraoperative complications in the open group. Conclusion:Robot guided balloon tibial osteoplasty for Schatzker II and III tibial plateau fractures had achieved satisfactory reduction, minimal bleeding, minimal trauma, short hospital stay, good knee joint function recovery, and satisfactory clinical results. However, attention should be paid to the issue of contrast agent leakage caused by balloon rupture.

Objective:To compare the short-term therapeutic effects of Gamma 3 U-Blade system and Gamma 3 nails in the treatment of elderly patients with osteoporotic unstable intertrochanteric fracture.Methods:The data of 70 elderly patients with osteoporotic unstable intertrochanteric fracture were retrospectively analyzed who had been admitted to the Department of Orthopedics, Wuhan Fourth Hospital from June 2018 to December 2020. They were divided into 2 groups according to their treatments. In the U-Blade group of 35 cases subjected to fixation with Gamma 3 U-Blade system, there were 14 males and 21 females with an age of (77.7 ± 4.8) years; in the Gamma 3 nail group of 35 cases subjected to fixation with Gamma 3 nails, there were 14 males and 21 females with an age of (79.3 ± 5.2) years. The 2 groups were compared in terms of operation time, intraoperative blood loss, apex distance, fracture union time, postoperative complications, timed up and go (TUG) at postoperative 2 weeks, 3 months and 6 months, and hip function at postoperative 9 months.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). There was no significant difference either in operation time, intraoperative blood loss or apex distance between the 2 groups ( P>0.05). The fracture union time [(12.0 ± 0.2) weeks] and Harris hip score at postoperative 9 months [90 (90, 91)] in the U-Blade group were insignificantly different from those in the Gamma 3 nail group [(12.0 ± 0.3) weeks and 91 (89, 91)] ( P>0.05). The rate of implant-related complications in the U-Blade group [0% (0/35)] was significantly lower than that in the Gamma 3 nail group [17.1% (6/35)] and the TUGs at postoperative 2 weeks and 3 months [(80.2 ± 3.6) s and 45 (43, 49) s] in the former were significantly shorter than those in the latter [(89.3 ± 4.2) s and 56 (54, 59) s] ( P<0.05). Conclusion:In the treatment of elderly patients with osteoporotic unstable intertrochanteric fracture, compared with traditional Gamma 3 nails, Gamma 3 U-Blade system can reduce implant-related complications and facilitate early recovery of walking ability.

Objective:To investigate the effect of subfibular ossicle excision on the clinical efficacy of Brostr?m procedure for chronic lateral ankle instability (CLAI).Methods:From March 2014 to December 2018, 76 patients were treated by the modified Brostr?m procedure using the suture anchor technique for CLAI at Department of Foot & Ankle Surgery, Wuhan Fourth Hospital. Of them, 33 had subfibular ossicles (SFO group) and 43 did not (NSFO group). In the SFO group, there were 19 males and 14 females, aged (28.4±8.6) years; in the NSFO group, there were 21 males and 22 females, aged (27.8±7.4) years. Subfibular ossicles were excised in the SFO group. The 2 groups were compared in terms of American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analogue scale (VAS) pain scores at preoperation and the final follow-up.Results:The 2 groups were comparable due to insignificant differences between them in their preoperative general data ( P>0.05). All the patients were followed up for 24 to 72 months (average, 28 months). The AOFAS ankle-hindfoot scores improved significantly from 54.5±3.4 to 95.7±2.1 in the SFO group and significantly from 56.2±2.7 to 95.2±2.4 in the NSFO group at the final follow-up; the VAS scores reduced significantly from 5.7±1.8 to 1.6±1.4 in the SFO group and significantly from 5.7±1.6 to 1.7±1.2 in the NSFO group at the final follow-up (all P<0.05). No significant differences were found between the 2 groups in terms of AOFAS or VAS scores at the final follow-up ( P>0.05). Conclusion:Since the modified Brostr?m procedure plus subfibular ossicle excision may result in similar good clinical efficacy as merely the modified Brostr?m procedure may for the CLAI patients without subfibular ossicle, subfibular ossicle excision should be suggested for the CLAI patients with subfibular ossicle.
