“…It should be noted that its volume and presence is determined by the implanted cup's position [14]. There are sources mentioning that a certain size of acetabular defect rules out the initial cup's stabilization or promotes the stability's loss in a long-term perspective [15,16]. Thus, the acetabular defect should be filled with bone grafts.…”

http://pjs.zaslavsky.com.ua Modern medicine tends to incorporate elements of globalized approach into the systematization of pathological conditions, while the synthetic processes are reserved for diagnostics and treatment. The above mentioned tendency gave rise to the notions of chronic venous disease (CVD), chronic obstructive pulmonary disease (COPD) etc. [1, 2]. Articular diseases make no exception. There is an opinion that hip arthritis should be divided into central and superolateral forms according to the displacement vector of the femoral head [3]. Each form may have its own causes. However, their end result is similar for both, having the same nature and clinical manifestations. The principal cause of superolateral form is the dysplastic change of hip joint. It induces the dysplastic hip arthritis, the degenerative-dystrophic condition, characterized by the developing articular tip deformity taking the pattern of acetabular wall defects or CCD (centrumcollum-diaphyseal) angle modification and/or femoral anteversion [4, 5]. At the moment, there are several classifications of dysplastic hip arthritis [6-9], which might be applied in hip arthroplasty. Crowe's classification is preferable while determining the extent of cranial displacement, as it gives a notion as to the arthroplastic difficulties and necessary manipulations to bring down the center of artificial joint rotation.

“…Most of the load is transferred through the cortical layer, and the spongy tissue works as a support material, preventing the cortical layer from collapsing. Due to age and other reasons that may cause degradation of bone tissue, the mechanical properties can change [14][15][16][17]. Bone tissue is anisotropic [12,14,18,19], and the distribution of Young's modulus depends linearly on the density.…”

Finite Element Analysis of Customized Acetabular Implant and Bone after Pelvic Tumour Resection throughout the Gait Cycle

The aim of this paper is to investigate and compare the stress distribution of a reconstructed pelvis under different screw forces in a typical walking pattern. Computer-aided design models of the pelvic bones and sacrum made based on computer tomography images and individually designed implants are the basis for creating finite element models, which are imported into ABAQUS software. The screws provide compression loading and bring the implant and pelvic bones together. The sacrum is fixed at the level of the L5 vertebrae. The variants of strength analyses are carried out with four different screw pretension forces. The loads equivalent to the hip joint reaction forces arising during moderate walking are applied to reference points based on the centres of the acetabulum. According to the results of the performed analyses, the optimal and critical values of screw forces are estimated for the current model. The highest stresses among all the models occurred in the screws and implant. As soon as the screw force increases up to the ultimate value, the bone tissue might be locally destroyed. The results prove that the developed implant design with optimal screw pretension forces should have good biomechanical characteristics.

“…Why is correct visualisation of the acetabulum at the preoperative planning stage so important ( 1, 2)? First, in the case of a single acetabulum cavity, the acetabulum cup can be implanted with some degree of cranial displacement.…”
