Here we present a protocol that generates large amounts of murine monocytes from heterogeneous bone marrow for translational applications. In comparison to others, this new method helps reduce the number of sacrificed animals and lowers costs by avoiding expensive methods such as high gradient magnetic cell separation (MACS).

This manuscript provides the detailed procedure of intra-iliac artery (IIA) injection, a technique to deliver cancer cells specifically to hind limb tissues including bones to establish experimental bone metastases. Although initially established with breast tumor models, this protocol can be easily extended to other cancer types.

Hydration of Cement

Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...

Soundness of Cement

The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create ettringite,...
FAQs
The injected polymethylmethacrylate cement hardens within the damaged bone, creating internal reinforcement at the fracture site. This added support can reduce painful movement of the weakened vertebra and help restore enough structural stability for improved mobility and function. The mechanism addresses mechanical weakness directly rather than requiring an open operation to stabilize the area.
Polymethylmethacrylate serves as the bone cement delivered into the weakened or fractured vertebra. Its clinically important property is that it hardens after placement, allowing it to remain within the bone and provide reinforcement. This conversion from an injectable material to a hardened support explains how the procedure can target structural instability and associated pain.
These conditions can produce painful vertebral compression fractures through different underlying disease processes, but the treatment rationale remains focused on the damaged bone. By reinforcing the affected vertebra, bone cement injection addresses the resulting structural weakness and fracture-related pain. This makes the approach relevant across several causes of vertebral injury rather than only osteoporosis.
In vertebral procedures, clinicians use image guidance to direct a needle into the damaged vertebra. They then deliver polymethylmethacrylate cement through the needle, allowing it to harden in place and reinforce the bone. Vertebroplasty and kyphoplasty are named vertebral approaches that use this general cement-delivery principle to treat the affected site.
The procedure is used primarily for painful vertebral compression fractures associated with osteoporosis, cancer, or trauma. Its minimally invasive nature makes it relevant when clinicians aim to stabilize the fracture site without open surgery. The intended clinical benefits include reducing pain and supporting mobility and function after structural damage has occurred.
By stabilizing the fracture site, clinicians can seek a reduction in pain together with improved structural support for the affected vertebra. That support may help patients maintain or regain mobility and function. The procedure therefore illustrates a broader medical strategy: using image-guided intervention to address a structural problem while avoiding the need for open surgery.
