During a posterior segmental spinal fusion procedure, a 71-year-old woman developed cardiac and pulmonary embolism characterized by nonsustained ventricular tachycardia during cement injection, rapid and severe hypoxemia, and hemodynamic instability. Management included exploratory cardiotomy under cardiopulmonary bypass and removal of the emboli from the pulmonary vessels. Postoperative recovery was successful, and the patient was discharged without sequelae. We discuss the pathophysiology of bone cement implantation syndrome during spinal fusion, possible causative factors, and treatment alternatives.

Osteoporotic vertebral compression fractures (OVCFs) can be painful. Percutaneous kyphoplasty (PKP) aims at strengthening the vertebra and reducing pain, but efficacy can vary among patients. The purpose of this study was to establish a risk prediction model for pain relief following PKP in patients with OVCF.

Geriatric femoral neck fractures are common orthopaedic injuries, which are associated with a high morbidity and mortality. Arthroplasty is the optimum treatment for many of these injuries, but debate exists regarding optimal surgical strategy. Multiple recent investigations have demonstrated strong superiority for cemented stems as compared with noncemented fixation with a decreased risk of periprosthetic fracture, shorter length of stay, lower cost, and decreased rate for revision surgery.

In dental implant surgery, infection is identified as the primary factor contributing to the failure of bone grafts. There is an urgent need to develop bone graft materials possessing antibacterial characteristics to facilitate bone regeneration. Magnesium phosphate bone cement (MPC) is highly desirable for bone regeneration due to its favorable biocompatibility, plasticity, and osteogenic capabilities.

Bone cement is commonly utilized to secure prosthetic joints in the body because of its robust fixation, stability, biocompatibility, and immediate load-bearing capability. However, issues such as loosening, leakage, and insufficient bioactivity can lead to its failure. Therefore, improving its mechanical, physical, and biological properties is crucial for enhancing its efficiency.

: to address the issue of burst drug release in antibiotic-loaded poly(methyl methacrylate) (PMMA) bone cement (ALBC), this study involved preparation of novel PMMA bone cement and determination of its antibacterial activity, biocompatibility, compressive properties, maximum temperature, and setting time. : a novel acrylic monomer, which contains the 3,4-dichloro-5-hydroxyfuran-2(5)-one (DHF), was synthesized and utilized to develop non-leaching antibacterial PMMA bone cement (NLBC), designated as DHF-methacrylic acid (DHF-MAA) bone cement. In the preparation of this bone cement, DHF-MAA served as a key component of the liquid phase.
