[Methyl methacrylate embedding technique. Its use in bone pathology (author's transl)]

Area of Science:

• Bone Histology
• Biomaterials Science

Context:

• Undecalcified bone biopsy processing is crucial for diagnosing metabolic bone diseases.
• Traditional embedding methods can be time-consuming and prone to artifacts, hindering accurate morphometric analysis.

Purpose:

• To introduce and evaluate a prepolymerized methyl methacrylate embedding technique for undecalcified bone biopsies.
• To assess the efficacy of this method in preserving tissue structure and facilitating diagnostic analysis.

Summary:

• A prepolymerized methyl methacrylate embedding technique for undecalcified bone biopsies is described, based on 588 cases.
• The method yields results within three days, significantly reducing retraction artifacts and preserving cellular structures.
• Post-deplastification, routine staining is feasible, enabling straightforward morphometric analysis and clear visualization of osteoid tissue.

Impact:

• This technique simplifies the diagnosis of osteomalacia and hyperparathyroidism by improving the quality of bone biopsy analysis.
• It offers a rapid and reliable method for bone histology, beneficial for clinical diagnostics and research.
