ABSTRACT

PURPOSE: The aim of this study was to investigate the clinical efficacy of full endoscopic lumbar annulus fibrosus suture in the treatment of single-segment lumbar disc herniation (LDH). METHODS: The clinical data of patients with single-segment LDH who underwent full endoscopic lumbar discectomy from January 2017 to January 2019 in our hospital were retrospectively analysed. Patients with full endoscopic lumbar discectomy combined with annulus fibrosus suture were divided into group A, and those with simple full endoscopic lumbar discectomy were divided into group B. The general information, surgery-related data, visual analog scale (VAS), Oswestry disability index (ODI), modified MacNab score at the last follow-up, reoperation rate and recurrence were compared between the two groups. RESULTS: All patients were followed up for 12 to 24 months, and the surgical time was 133.6 ± 9.6 min in group A and 129.0 ± 11.7 min in group B. The difference was not statistically significant (p > 0.05). The blood loss of group A was higher than that of group B, and the difference was statistically significant when comparing the groups (p < 0.05). The postoperative symptoms of patients in both groups were significantly relieved, and the VAS score of low back pain and ODI index were significantly lower than the preoperative ones at all postoperative time points (1 month after surgery, 3 months after surgery, and at the last follow-up) (p < 0.05), but there was no significant difference between the groups (p > 0.05). The excellent rate of MacNab at the last follow-up in the two groups were 93.55% and 87.80%, respectively, with no statistically significant difference (p > 0.05). At the last follow-up, the recurrence rate of group A was significantly lower than that of group B, and the difference was statistically significant (p < 0.05), while the difference between the reoperation rate of the two groups was not statistically significant (p > 0.05). CONCLUSIONS: Full endoscopic lumbar discectomy combined with annulus fibrosus repair reduces the postoperative recurrence rate and achieves satisfactory clinical outcomes.

ABSTRACT

Aim: The aim of this study was to provide a comprehensive overview of floating hip injury and attempt to provide a management algorithm. Methods: PubMed was searched using the terms 'Floating hip' or 'acetabular fracture' and 'Ipsilateral femoral fracture' or 'pelvic fracture' and 'Ipsilateral femoral fracture'. One author performed a preliminary review of the abstracts and references of the retrieved articles. Results: The mean injury severe score reported was higher than 20. Chest and abdominal injuries, as well as fractures at other sites, were the most common associated injuries. Despite the high disability rate, surgery remained the preferred option for managing these injuries. The surgical timing varied from a few hours to several days and was subjected to the principles of damage control orthopedics. Although, in most cases, fixation of femoral fractures took precedence over pelvic or acetabular fractures, there was still a need to consider the impact of damage control orthopedics, associated injuries, and surgeon's considerations and preferences. Posttraumatic arthritis, neurological deficits, heterotopic ossification, femoral head necrosis, femoral nonunion, and limb inequality were common complications of the floating hip injury. Conclusions: The severity of such injuries often exceeds that of an isolated injury and often requires specialized multidisciplinary treatment. In the management of these complex cases, the complexity and severity of the injury should be fully assessed, and an appropriate surgical plan should be developed to perform definitive surgery as early as possible, with attention to prevention of complications during the perioperative period.

ABSTRACT

OBJECTIVES: Percutaneous vertebroplasty (PVP) is a percutaneous interventional procedure for osteoporotic vertebral compression fractures (OVCFs). However, hidden blood loss (HBL) during the surgery is easily disregarded. This study aimed to evaluate HBL and its possible risk factors in the patients following PVP for OVCFs. METHODS: Patients with OVCFs who underwent PVP surgery between January 2019 and November 2022 at our hospital were retrospectively analyzed. Patients' demographics, laboratory data, and imaging and clinical date were also collected. Preoperative and postoperative hematocrit were recorded, the hidden blood loss was calculated according to Sehat formula, and the risk factors were analyzed by multivariate linear regression analysis. RESULTS: One hundred and fifty-five patients (26 males and 129 females) were retrospectively enrolled in this study. 85.2% of patients had one segment vertebral fracture and the mean surgical time was 30.5 ± 11.0 min. No intraspinal cement leakage occurred. The mean HBL was 204.0 ± 89.6 ml. Multivariate linear regression analysis revealed that HBL was positively associated with number of fracture segments (P = 0.001), degree of vertebral height restoration (P = 0.001), surgical time (P = 0.000), number of puncture (P = 0.002), and cement leakage (P = 0.038). CONCLUSIONS: Multiple vertebral fractures, higher degree of vertebral height restoration, longer surgical time, more number of puncture, and cement leakage are independent risk factors for HBL. Therefore, HBL should not be neglected in the patients with OVCFs undergoing PVP surgery, especially in those with poor preoperative physical condition and presence of anemia.

ABSTRACT

BACKGROUND: Osteosarcoma is the most common type of bone cancer in children and young adults. Recent studies have shown a correlation between epithelial-mesenchymal transition (EMT)-related gene expression and immunity in human cancers. Here, we investigated the relationship among EMT, immune activity, stromal activity and tumor purity in osteosarcoma. METHODS: We defined EMT gene signatures and evaluated immune activity and stromal activity based on the gene expression and clinical data from three independent microarray datasets. These factors were evaluated by single sample Gene Set Enrichment Analyses and the ESTIMATE tool. Finally, we analyzed the key source of EMT gene expression in osteosarcoma using microarray datasets from the Gene Expression Omnibus and human samples that we collected. RESULTS: EMT-related gene expression was positively correlated with immune and stromal activity in osteosarcoma. Tumor purity was negatively correlated with EMT, immune activity and stromal cells. We further demonstrated that high EMT gene expression could significantly predict poor overall survival (OS) and recurrence-free survival (RFS) in osteosarcoma patients, while high immune activity cannot. However, combining these factors could have further prognostic value for osteosarcoma patients in terms of OS and RFS. Finally, we found that stromal cells may serve as a key source of EMT gene expression in osteosarcoma. CONCLUSION: The results of this study reveal that the expression of EMT genes and immunity are positively correlated, but these signatures convey disparate prognostic information. Furthermore, the results indicate that EMT-related gene expression may be derived from stromal rather than epithelial cancer cells.
