Vertebroplasty and kyphoplasty - advantages and disadvantages used bone cement of PMMA

Choryłek P.

Journal of Achievements in Materials and Manufacturing Engineering

2019

Vol. 92, nr 1-2

36--49

Purpose: This paper is a review of literature where the analyses of the commonly used bone cements were carried out especially: methods of manufacturing, surgical techniques, mechanical properties, biocompatibility studies as well as possibility of improvement some properties by using additives. Design/methodology/approach: The aim of this publication is the analysis of the state of knowledge and treatment methods on compression fractures, approximation of the specifics of compression fractures, presentation of minimally invasive percutaneous surgical techniques, description of features of the most common used bone cement on matrix Poly(methyl methacrylate) – (PMMA) and presentation cement parameters which affect potential postoperative complications. Findings: In considering to review of actual state of knowledge there is a need to find the additives which allow: to reduce the polymerization temperature, improve the biocompatibility as well as mechanical properties. During the studies it was found that the additive which can meet the requirements is glassy carbon in form of powder. Practical implications: Discussion allows to prepare samples during practical work with new kind additives in composite with bone cement as matrix. Originality/value: The original in this discussion is the possibility to improve fundamental properties of the selected bone cements by using different than commonly used additives.

W pracy przedstawiono model geometryczny odcinka piersiowo lędźwiowego kręgosłupa (Th12 - L2), ze złamanym kompresyjnie trzonem kręgu L1 wraz z systemem korekcyjno - stabilizacyjnym USS Fracture System. Opracowano modele geometryczne struktur anatomicznych w tym trzonów Th12, L2 oraz połamanego trzonu L1, tkanek miękkich, czyli: więzadeł podłużnych: przedniego ALL i tylnego PLL oraz krążków międzykręgowych, jak również modele implantów zastosowanych do dwupoziomowej stabilizacji. Wykorzystano dane CT pacjenta oraz oprogramowanie Mimics 13.1 i SolidWorks 2010.

A geometrical model of the two-level-stabilization of human thoraciclumbar spine (Th12 – L2) with compressive fractured L1 vertebral body has been presented in the paper. The developed model comprises both the aforementioned bone anatomical structures and the soft tissue ones (anterior and posterior longitudinal ligaments (ALL, PLL) and spinal discs) and models of the applied USS Fracture system of implants. CT data of a patient and the Mimics 13.1 and SolidWorks 2010 software packages have been used in the modeling procedure.
