Filter by:Background : Vertebral fracture is the most common complication of osteoporosis. Vertebroplasty is a widespread treatment modality for osteoporotic vertebral fractures, providing consolidation, rapid pain relief and preventing secondary vertebral collapse. Performing a biopsy at the same time as the operation does not lengthen the procedure or increase the risk of complications. The question therefore arises as to whether it is cost-effective diagnostically: are non-osteoporotic vertebral lesions detected when biopsies are taken? Methods: The investigators carried out a single-centre retrospective study at Nice University Hospital. From January 2016 to March 2022, 1729 biopsies were performed during 1439 vertebroplasty procedures on 1120 patients. The pre-operative laboratory work-up included a blood count, a C-reactive protein assay and a coagulation test. The imaging work-up systematically included MRI, unless contraindicated, in which case CT alone was performed. Vertebroplasty was performed in an interventional CT suite under dual CT and fluoroscopic guidance. The systematic biopsy sample was then sent to the anatomopathology department for analysis. Findings : The samples detected cancer in 35 patients, including 5 (0.44%) for whom the pre-operative work-up had not raised any suspicion. All the incidental findings were haemopathies, including 4 myelomas and one lymphoma. Conclusion : These results highlight the good performance of MRI in distinguishing osteoporotic vertebral fractures from solid tumour metastases. However, an exhaustive pre-operative work-up does not seem to be able to formally rule out an underlying malignant lesion. The investigators therefore recommend that biopsies be taken systematically when performing vertebroplasty.
Over the last months, the Rizzoli Orthopedic Institute in Bologna, Italy, has drained orthopedic urgencies from all other hospitals in the urban and suburban area. In this context urgencies are defined as fractures and primary or metastatic bone lesions with indication to non-deferrable surgery. A subset of these patients tested positive for SARS CoV 2, either before or after the surgical procedure. Anesthesiological clinical management of covid19 cases is complicated by the consequences of the viral infection on respiratory and cardio-vascular systems, renal function and coagulation. Similarly, management of asymptomatic patients is challenging because of the lack of data on possible specific complications. This study will report a snapshot of our early experience on perioperative clinical management of patients undergoing orthopedic surgery in the presence of SARS CoV 2 infection, ascertained or not at the time of surgery.
The goal of this clinical study is to evaluate the duration of the procedure, the precision (distance between the needle tip and the centre of the target), and the safety of endosight system in the guidance for bone biopsies.
The goal of this clinical trial was to assess the diagnostic performance and safety of Sodium Fluoride F-18 Positron Emission Tomography / Computed Tomography (18F-NaF-PET/CT) in bone metastases of malignant tumors compared with Technetium[99mTc] Methylenediphosphonate Bone Scintigraphy ± Single Photon Emission Computed Tomography (99mTc-MDP-BS±SPECT). The enrolled subjects were randomly assigned to two sequences A and B at a ratio of 1:1. Within 7 days, 18F-NaF-PET/CT and 99mTc-MDP-BS±SPECT bone imaging were performed alternately. The sensitivity, specificity, positive and negative predictive value of 18F-NaF-PET/CT and 99mTc-MDP-BS±SPECT were calculated respectively based on the diagnostic data of standard of truth.
In the population suffering from cancer, children and teenagers are in the majority. For children with rapid development of body and mind, with the change of cognitive ability, they will feel anxiety and fear about the expected potential negative events. Painting art therapy is a kind of non-verbal psychological therapy through the interaction between the painter, the painting work and the therapist, with the painting creation activity as the intermediary. The purpose is to develop symbolic language, touch the inner subconscious, and integrate into the personality, so as to produce cognitive and behavioral changes. Painting therapy and psychological analysis can improve the treatment compliance of children bone tumor patients, make psychological nursing and health education of patients more targeted, and promote the cooperation between medical care and patients.
This is a retrospective observational real-world study, which evaluates the efficacy and safety of denosumab and non-denosumab therapies in the treatment of Chinese populations of surgically unsalvageable or severe post-surgery morbidity associated giant cell tumor of bone (GCTB), collectively referred to as unresectable GCTB, during 2013-2021 in three medical centers, serving as the external control for a single arm phase Ib/II trial on JMT103 treatment of GCTB. 301 patients were enrolled and divided into 2 groups according to their actual previous exposures. Group 1 (n=135) was denosumab group. Group 2 (n=166) included two types of exposures other than denosumab: other anti-GCTB drug therapies, or no therapy on GCTB patients. The dosage, route, frequency and other administration methods was collected according to the actual previous treatment records. The primary outcome measure was the tumor response rate [radiographic tumor response (CR/PR evaluated by ICDs or EORTC criteria) within 12 weeks, or at least 90% reduction of osteoclast like giant cells compared with baseline]. The key secondary endpoint was the tumor response rate [radiographic tumor response (CR/PR evaluated by ICDS or EORTC criteria), or at least 90% reduction of osteoclast like giant cells compared with baseline]. Other secondary Outcome Measures include: proportion of patients whose tumors was surgically resectable; median duration of tumor response (DOR), disease control rate (DCR), and time to disease progression (TTP); and types and proportion of key adverse reactions.
Tumor resection and prosthetic replacement have become the treatments of choice for malignant bone tumors. Infections are the main cause of failure of limb salvage surgeries. Therefore, treatment of infections around prostheses after limb salvage is important, but is also challenging. Our research team designed a "domino" sequential treatment plan to treat postoperative infections around tumor prostheses and evaluated its efficacy.
Patients with a biopsy-proven benign bone tumor for which standard of care is intralesional operative management will receive a weight-appropriate IV dose of indocyanine green (ICG, FDA-approved) the day prior to surgery during their standard pre-operative clinic visit. On the day of surgery, fluorescence images will be obtained using a non-invasive fluorescence camera.
Up to 45 Patients aged 12 to 39 with osteosarcoma (bone cancer) that had recurred in the lungs and has recently been surgically removed will be enrolled. Patients will receive OST31-164 infusions every 3 weeks over 48 weeks and be followed after that for 3 years.
In this study, we retrospectively analyzed the imaging data of spinal tumors to find out more imaging features of spinal tumors, in order to provide more accurate reference for the diagnosis of spinal tumors.
