Abstract:
Introduction Total hip arthroplasty in defects of the acetabulum is a complex type of surgical intervention, and the search for optimal implants and bone substituting materials to restore the integrity of the acetabulum is one of the current problems. The aim of the work was to analyze the results of primary and revision hip arthroplasty with compensation of acetabulum defects.Materials and methods The study material consisted of 93 patients with primary (65) and revision (28) total hip arthroplasty in the presence of bone defects of the acetabulum of varying severity. To systematize primary defects, the classification of the American Association of Orthopedic Surgeons (AAOS, 2017) was used; for defects in revision surgeries, the classification of W.G. Paprosky (1994) was used. Clinical, radiological, and statistical study methods were used. The results of managing bone defects of the acetabulum with various methods of compensation were studied. The Harris Hip Score (HHS), 1969, was used to assess the function of the involved joints.Results Depending on the type of acetabular defects, an algorithm was developed for choosing a bone grafting method for acetabular defects and implanting the cup. The best results were observed for cases of a combination of resorbable and non-resorbable bone graft materials and cementless fixation of the pelvic component. A clinical example of three consecutive revision interventions on one hip joint in a patient with bilateral dysplastic coxarthrosis is presented.Discussion The most widely used method of bone grafting in primary arthroplasty is plastic surgery with autologous chips from the femoral head. In significant bone tissue loss, one of the plastic surgery options is a structural auto- or allograft, the use of which allows restoring the rotation center and forming a bone support for possible future revisions; poor results with this method are caused by allograft lysis. In revision arthroplasty on the hip joint in large defects, plastic surgery of the defect is performed with crushed or structural allograft bone. An antiprotrusion constructs or cups made of trabecular metal are installed; in instability of the pelvic ring, osteosynthesis of the posterior column is required. Trabecular metal structures feachuring high porosity and adhesion to bone and the elastic modulus close to bone tissue provide conditions for optimal primary and secondary fixation of the component.Conclusion Long-term and painless functioning of the hip joint after arthroplasty performed for acetabular defects is possible with restoration of the spherical shape of the acetabulum and the center of joint rotation in the true acetabulum, adequate elimination of bone tissue loss, reliable primary fixation of the cup with provision of conditions due to restoration and osteointegration. Acetabular defects are diverse in their anatomical manifestations, which create difficulties in choosing pelvic components, augments, and the method of their fixation to the pelvic bone. Based on the type of the acetabular defect, an algorithm has been developed for choosing a method for acetabular bone defect filling and implanting a cup.

Abstract:
Abstract Background: Most of the revision hip arthroplasties have some sort of acetabular bone defects. These defects are usually managed with some sort of metal augments. These metal augments might make the bone weaker and fragile and revisions may become difficult. Aim of Study: This study aimed to study the outcome of various types of acetabular defects managed with bone grafts. Materials and Methods: Ten patients with acetabular defects requiring separate management planning (Paprosky classification of acetabular defect) for total hip arthroplasty from May 2020 to May 2021 were selected and followed for further 2 years. Results: Acetabular defect was classified preoperatively with three-dimensional computed tomography scan. In all the cases, the bone graft healed radiographically with no signs of loosening of the acetabular cup. Conclusion: Conservative acetabular revision (reconstruction of the bone defect with bone graft) is the need of the hour. Reconstruction by bone graft has a smooth learning curve.

Abstract:
Acetabular reconstruction is a necessary condition for improving the survival rate and proper functioning of the implant. The issue of compensation for bone loss remains one of the most difficult and controversial in orthopaedics. The article aimed to analyze approaches to the problem of management of acetabular defects in hip replacement. The paper presents the key features of the anatomy and radiological anatomy of the acetabulum. Modern modifications of acetabular components of an endoprosthesis, their advantages and disadvantages, as well as ways to compensate for acetabular bone loss with bone substitute materials are considered. The review highlights the use of 3Dprinting technologies, the interaction between physicians and other experts in this field. Currently, an active search for materials, alternatives to autogenous bone, as well as ways to facilitate the design and reduce the negative impact of the implant on the patient's bone tissue continues. The use of additive technologies seems to be the most promising direction that allows applying an individual approach to each clinical case, but it is available only in specialized centres and is associated with significant material, technical and legal difficulties. Stable fixation of the acetabular component, according to the literature, is achieved under the condition of restoration of hip rotation centre in the native acetabulum area, restoration of normal anatomical relations in the hip joint and adequate replacement of bone loss.

Abstract:
Purpose of the study — to improve the two-dimensional planning of total hip joint arthroplasty to ensure precise positioning of the acetabular component in the deformed acetabulum. Materials and methods. Features of roentgenological anatomy of acetabulum and its coverage were studied on 1058 hip joint x-rays in the AP view in accordance with the procedure developed by the authors to define acetabular square — the site of standard positioning of a spherical femoral head in the acetabulum or of a hemispherical acetabular component. The method consisted of identifying the apex of “teardrop” figure; the most lateral points of the pelvic terminal line and roof of the acetabulum; superior part of the acetabular cavity; medial and inferior points of acetabular coverage, and building the sides of acetabular square — medial, inferior, lateral and superior boundary lines. Connection of “teardrop” apex and lateral point of the pelvic terminal line formed the medial side of acetabular square, and a perpendicular to that line drawn through the “teardrop” apex to its inferior side. The lateral side was drawn either through the intersection of the ascending diagonal line — bisector from the top of the “teardrop” figure with the contour of the acetabulum roof, or was a part of the projection of the most lateral point of the acetabular roof on the inferior side of the square. The superior side was a perpendicular connecting the intersection of the ascending diagonal and lateral bounding lines with the medial side of the acetabular square. The area of the deformed acetabular cavity located outside of the acetabular square was assessed as the acetabular defect. Results. Method of defining the acetabular square allowed to identify types of ratios between acetabular cavity and acetabular coverage in transverse (9 types) and longitudinal (7 types) direction. Combination of transverse ratio of acetabular cavity and coverage with longitudinal type allowed to define the options of acetabular deformities in two-dimensional view. The authors identified 25 types of acetabular deformities. Bone defects of acetabular walls were of the major importance among all anatomical features. Cranial defect of acetabulum was observed in 450 cases, medial wall defect — in 38 cases, defect including cranial and medial areas — in 7 cases. Conclusion. The method suggested by the authors to determine acetabular square and acetabular deformity variations allows to screen the anatomical features of the acetabulum during two-dimensional preoperative planning and to make an informed decision on the need to use other planning techniques. The type of acetabular deformity identified during preoperative planning allows to elaborate the indications for replacement of acetabular bone defects and/or resection of acetabular osteophytes.

Abstract:
Introduction Reconstruction of the acetabulum during revision arthroplasty is a challenging task in the setting of massive bone defects. Often the only effective method is impaction bone grafting (IBG). The purpose is to demonstrate the capabilities of the X-Change impaction bone grafting technology in replacing acetabular defects as a method of choice for revision hip arthroplasty.Materials and methods In the presented series of cases, the use (IBG) turned out to be the method of choice, allowing for high-quality reconstruction. In each presented case, revision hip arthroplasty was performed with augmentation with a reconstructive mesh or trabecular metal augment to create support and contain the defect to retain the osteoplastic material.Results During follow-up periods of 4.8 to 6.5 years there were no signs of resorption or loosening. According to the Harris hip score the results were 96, 97 and 89 points respectively.Discussion Impaction bone grafting technology is quite versatile. It can be used in various coditions of revision arthroplasty with contained defects of the acetabulum. In contrast to the use of modular revision augmentation systems and additive technologies it makes possible to achieve dense filling of the smallest defects and profile a bed congruent with the acetabular component. The use of cemented fixation makes it possible to further stabilize the impacted bone chips and use mechanotransduction mechanisms that stimulate the bone remodeling. The use of IBG has proven to be an effective technique for the reconstruction of medium-sized acetabular defects in combination with mesh and cement cup, as well as in combination with trabecular metal augments.Conclusion The use of IBG during revision hip arthroplasty can be especially effective for small acetabulum sizes. Combining IBG with trabecular metal augments significantly expands the application of this technology. The use of IBG makes it possible to create a bone reserve, which creates more favorable conditions for inevitable repeated revision interventions.

Abstract:
This study aims to evaluate the reconstructive stability for Paprosky III acetabular defects after total hip arthroplasty using three different reconstruction strategies with trabecular metal (TM) augments. The acetabular bone defects examined were located in the ilium, the sciatic ramus and the pubic ramus. Different scenarios of acetabular reconstructions were simulated, including the non-reconstruction model (NRM), the complete reconstruction model (CRM), the two-point reconstruction model (TRM) and the superior edge reconstruction model (SRM). A primary hip replacement model (HRM) was also investigated to compare the initial stability with different reconstruction models. The gait cycle was incorporated in the model to investigate the dynamic variation within the contact mechanics parameters. By comparing the SRM and the TRM, the acetabular cup translation was more pronounced when the superior defect on the acetabulum remained unfixed. Comparison of the acetabular cup displacement and the interface micromotion of both HRM and CRM demonstrated that the prosthetic implant provided good support for the reconstructed acetabulum. With the use of a press-fit cup, the cup displacement was reduced remarkably, while its Von-Mises stress increased significantly. The results show that the CRM was the best reconstruction option. In terms of acetabular defects, future improvements should focus on the reconstructive stability in stress concentration areas, to ensure no significant stress-shielding or other factors contributing to loosening of the prosthesis.

Abstract:
Introduction Due to the constant increase in the number of primary and revision hip arthroplasties, the incidence of complications has been also increasing. Periprosthetic joint infection (PJI) is the most common and dangerous complication in joint arthroplasty, including PJI with cavitary defects of the acetabulum (Paprosky type 2C).The purpose of the work was to demonstrate successful results of managing acetabular defects in patients with periprosthetic infection at the stage of installing an articulating spacer.Materials and methods The patients underwent surgical management of cavitary defects of the acetabulum with allobone plastic material at the stage of installation of an articulating spacer impregnated with antibacterial drugs. A clinical and functional assessment of the effectiveness of treatment of patients with PJI of the hip joint, who underwent bone grafting of acetabular defects at the first stage of two-stage revision arthroplasty, was carried out. Remission of the infectious process was assessed according to the ICM 2013 (International Consensus Meeting), and the function of the affected limb was assessed according to the HHS (Harris Hip Score).Results At a 6-month follow-up after implantation, there were no clinical and laboratory manifestations of PJI and radiological signs of instability of the implant components. Bone grafting was evaluated to be satisfactory; the function of the affected joint restored to 80–90 to HHS points. Remission of the infectious process according to ICM was achieved.Discussion Clinical cases studied demonstrate a positive result of treatin PJI with plastic surgery of cavitary defects of the acetabular bottom at the stage of articulating spacer installation. Filling acetabular defects at the sanitizing stage (implantation of a spacer) subsequently provides improvement of primary fixation and osseointegration of the acetabular component when converting the spacer to a permanent implant. This is due to an increase in the contact area of the acetabular component with bone tissue (native bone and remodeled allobone material).Conclusion The treatment of the first clinical case improved joint function from 24 to 85 HHS points, and in the second from 27 to 76 HHS points. The use of defect filling techniques enabled to stop the infection and improve functional results.

Abstract:
Introduction. During arthroplasty in patients with altered anatomy and osteoporosis of the acetabulum, stable fixation of the acetabular component of the endoprosthesis is a very difficult task. There are studies on the bone tissue bonding to titanium, tantalum and ceramic coatings of endoprostheses. However, there are insufficient data on the influence of the strength characteristics of modern surfaces of the cups for hip endoprostheses on the distribution of mechanical stresses in the bone tissue around the implanted components. The purpose was to study on a mathematical model the changes in the stress-strain state of the endoprosthesis-bone system as a result of using porous tantalum cup. Materials and methods. A mathematical modeling has been carried out of the stress-strain state of the human hip joint in arthroplasty with porous cup. Du-ring the study, a defect in the acetabular roof filled with a bone implant fixed with two screws was simulated, as well as a defect in the acetabular floor filled with bone “chips”. Endoprosthesis cups were modeled in two versions: from solid titanium with a spray coating of porous titanium, and those entirely made of porous titanium. A distributed load of 540 N was applied to the sacrum. A load was applied between the iliac wing and the greater trochanter of the femur simulating the action of the gluteus medius — 1150 N and the gluteus minimus — 50 N. Results. The use of a cup with a coating of porous titanium in the normal state of the acetabulum leads to the occurrence of maximum stresses (15.9 MPa) in its posterior-upper part. Minimum stresses of 4.6 MPa are observed in the center of the acetabulum. The use of an endoprosthesis with porous titanium cup allows reducing the level of stresses in the bone tissue around the cup. If there is a defect in the acetabular roof, a hip endoprosthesis with porous titanium cup causes less stress than a solid titanium cup with coating of porous titanium. But on the graft, the stress level remains practically unchanged, regardless of the type of cup. The use of porous tantalum cup in the presence of a defect in the acetabular floor causes significantly less stress in the bone tissue around it, compared to an all-metal cup with coating. Conclusions. The cup of the hip endoprosthesis made of porous titanium causes significantly less stress in all control points of the model, compared to a cup made of solid titanium with coating of porous titanium, both with defects in the acetabular roof and floor, and without bone defects.

Abstract:
Using morselized and structural allograft to restore bone stock for massive acetabular bone defect in revision total hip arthroplasty (THA) is an appealing procedure. However, concerns about inability to achieve long-term stability following allograft resorption remained. From 2003 to 2012, 59 hips in 58 patients undergoing revision THA for Paprosky type II or III acetabular defects were retrospectively reviewed. The acetabular defects were managed with deep-frozen morselized and structural allografts, and a press-fit cementless cup along with supplementary screws. Clinical outcomes and radiographic results were analyzed with a mean follow-up of 8.7 years. The clinical successful rate was 100% for hips with Paprosky type II defect, 95.2% for IIIA defect, and 92.8% for IIIB defect. Three hips with type III defect failed at 4, 7, and 9 years, respectively. Harris Hip Score improved significantly from 60.1 preoperatively to 91.3 at the latest follow-up. All hips with good clinical results showed trabecular bridging in the allograft-host bone interface. Deep-frozen structural and morselized allograft in combination with a press-fit cementless cup represented a viable option to reconstruct acetabular defects in revision THA.

Abstract:
The aim: The purpose of the article is to analyze the ways of solving the problem of revision hip joint replacement. The article discusses the methods of treatment using a custom triflange acetabular component. Materials and methods: The analysis of 37 literary sources includes a discussion of the features of the use of individual triflange acetabular components and errors in revision hip arthroplasty, which are associated with various factors. Conclusions: A review of studies devoted to the use of custom triflange acetabular components confirms the effectiveness in the early postoperative period in the treatment of critical acetabular defects and pelvic ring discontinuity. The CTAC use is particularly relevant in case of the pelvic ring disintegration, as it provides for the appropriate endoprosthesis adaptation with the healthy bone, as well as for the bone defects plastics and recovery of the hip joint biome¬chanics. So, the use of individual constructions is indicated for the patients with significant bone mass loss, where augment adaptation and adjustment is impossible. This method is used more often when there is no other alternative. Research results showed a trend that special three-flange components of the acetabulum have better long-term results compared to traditional standard components for large bone defects. Improving production and increasing the number of CTACs should reduce their cost. In summary, the custom triflange acetabulum components provide a personalized secure fit that can reduce the risk of complications and improve patient outcomes. In summary, the triple-flange acetabulum components provide a personalized secure fit that can reduce the risk of complications and improve patient outcomes.

Abstract:
The revision hip arthroplasty is a surgical procedure, consisting in the reconstruction of the hip joint through the replacement of the damaged hip prosthesis. Several factors may give raise to the failure of the artificial device: aseptic loosening, infection and dislocation represent the principal causes of failure worldwide. The main effect is the raise of bone defects in the region closest to the prosthesis that weaken the bone structure for the biological fixation of the new artificial hip. For this reason bone reconstruction is necessary before the surgical revision operation. This work is born by the necessity to test the effects of bone reconstruction due to particular bone defects in the acetabulum, after the hip prosthesis revision. In order to perform biomechanical in vitro tests on hip prosthesis implanted in human pelvis or hemipelvis a practical definition of a reference frame for these kind of bone specimens is required. The aim of the current study is to create a repeatable protocol to align hemipelvic samples in the testing machine, that relies on a reference system based on anatomical landmarks on the human pelvis. In chapter 1 a general overview of the human pelvic bone is presented: anatomy, bone structure, loads and the principal devices for hip joint replacement. The purpose of chapters 2 is to identify the most common causes of the revision hip arthroplasty, analysing data from the most reliable orthopaedic registries in the world. Chapter 3 presents an overview of the most used classifications for acetabular bone defects and fractures and the most common techniques for acetabular and bone reconstruction. After a critical review of the scientific literature about reference frames for human pelvis, in chapter 4, the definition of a new reference frame is proposed. Based on this reference frame, the alignment protocol for the human hemipelvis is presented as well as the statistical analysis that confirm the good repeatability of the method.

Abstract:
This thesis describes work, the aim of which was to develop a computed tomography (CT) technique that provides accurate and reliable volumetric measurement of bone defects adjacent to uncemented metal-backed acetabular components of total hip replacement (THR). Periprosthetic osteolysis (PO) around THR is a major clinical problem in the mid-to long term post-operative period. Some implants remain well fixed in the presence of significant bone loss, and the hips may also be asymptomatic. However, undetected, the PO can lead to dramatic implant failure, or periprosthetic fracture, requiring complex and expensive revision surgery, with associated morbidity. Clinical assessment of THR for PO has relied on plain radiographs. However, numerous studies have shown that there are major limitations of this method in detecting the presence and extent of osteolysis and the volume of the defects cannot be quantified. Therefore, clinical management decisions regarding the need to revise prostheses for PO have been based on this unreliable diagnostic tool. Until recently, the use of CT to detect and measure defects was not effective because of the resulting artifact from the metallic components of the THR prostheses. The studies described in this thesis represent the development, validation and the clinical application of a CT technique for quantification of acetabular periprosthetic osteolysis after THR. In the first in-vitro validation study, a CT protocol was developed using a conventional CT scanner with limited CT scale (up to 4,000 Hounsfield units [HU]). The CT operating conditions were determined that enabled volumetric measurements that were accurate to within 96% for small and large defects and precise to greater than 98% for small and large defects. Since the ilium is the most commonly affected site by PO, and is an area almost free of metallic artifact, this technique is applicable for use with conventional CT scanners with limited CT scale. In the second in-vitro validation study, a CT protocol was developed to use a multi-slice spiral CT scanner with an extended CT scale (up to 40,000 HU) for the measurement of acetabular periprosthetic bone defects. This technique enabled volumetric measurements of bone defects in all acetabular and periacetabular areas. In the third study, the clinical application of the developed CT technique was investigated in two sub-studies. The aim of the first clinical studywas to determine, using quantitative CT, the distribution, volume and rate of progression of PO lesions around 46 cementless THR prostheses in 33 patients. The findings showed that, in the long term, there were differences in the distribution of osteolytic lesions between different designs of cementless acetabular components. In particular, osteolysis commonly involved sites of access of the joint fluid- the peripheral region of the components, where prosthesis fixation is important, and fixation screw holes. The aim of the second clinical study was to use quantitative CT to determine the progression of osteolysis and the factors that may associate with it, including component migration, liner polyethylene wear, and patient variables, in 30 patients with 38 cementless acetabular components. The data provided the first reliable information on the progression of osteolytic lesions around uncemented THR prostheses and suggested that, for THR, the rate of polyethylene wear is a strong predictor of PO progression. The results from in-vitro studies and the findings from the clinical studies suggest that the use of this CT technique allows investigation of the natural history of osteolytic lesions, and will enhance preoperative planning, improve monitoring of THR patients, and enable measurement of the outcomes of new ways to manage PO.<br>Thesis (M.S.) -- University of Adelaide, School of Medicine, 2009

Abstract:
Osteolysis of the pelvis after total hip replacement (THR) can result in several types of bony defects within or around the acetabulum [1]. These defects are classified into various categories based on the extent and location of the host bone loss [2, 3]. A severe acetabular defect with at least 30% of bone loss and progressive amounts of superior rim deficiencies can be classified as a Paprosky type IIIA cavitary defect [4] (Figure 1-I). A significant amount of superior migration of the cup can be expected as the deficient acetabulum with nonsupportive superior dome will be unable to support an acetabular component at the anatomic hip center without using structural allograft, custom implants or reconstruction cage [4, 5]. A new reconstructive technique (Figure 1-II) uses modular Trabecular Metal™ (TM) augments (Figure 1-III) to fill the acetabular defects at the time of revision THR so that regular hemispheric uncemented acetabular components can be used to allow for the potential of biologic fixation.

Abstract:
Custom 3D printed titanium acetabular implants have only recently been introduced and enable surgeons to treat traditionally unreconstructable massive acetabular defects. Whilst there is an accepted threshold for implant migration (proximal translation of &gt;1 mm within 2 years) that constitutes loosening in primary and revision uncemented hip implants, there is no reference threshold for custom acetabular implants used to treat massive defects, with no long-term outcome studies [1]. Aim: We performed bone-to-bone registration of sequential CT imaging with the aim to help define radiological loosening of custom-made three- dimensionally 3D printed trabecular titanium cups for the management of massive acetabular defects. Objectives: Our primary and secondary objectives were to assess implant position and orientation 1-year post surgery in comparison with the immediate post-operative CT imaging.

Abstract:
Introduction: Breast cancer is the most common neoplasm in women, excluding non-melanoma skin neoplasm, and it represents 22% of new cases each year. Due to treatment breakthroughs, patient survival has increased, which indicates that social and functional rehabilitation through chest wall reconstruction is its paramount component. Objective: This study aims to report a case of a patient with recurrent breast cancer and the need for chest wall reconstruction. Case report: LLVA 47 years old, with cancer on her right breast treated with partial mastectomy, radiotherapy, and chemotherapy, which evolved into a chest wall undifferentiated pleomorphic sarcoma. A complex thoracotomy was performed in oncology with tumor resection on the right chest wall and resection of the 3rd, 4th, 5th, and 6th costal arches, followed by a reconstruction, accomplished with 2 acetabular plates and a 42-cm polypropylene mesh. Afterward, a rotation of myocutaneous flaps with latissimus dorsi and transversus rectus abdominis (TRAM) with a contralateral pedicle was performed. The patient evolved with fair flap perfusion. Discussion: Plastic surgeons’ participation in oncological treatments has shown increasing importance, allowing the performance of large resections that could be considered unresectable without their repair. Thus, reconstruction is essential to increase quality of life and to provide local conditions for accessorial treatment. During chest wall reconstruction, the technical difficulty lies in the extent of resections, requiring reconstruction of the costal bone framework when there is resection of four or more ribs or when there is a lateral defect greater than 5 cm. The most commonly used flaps are the latissimus dorsi myocutaneous and the TRAM flap. Conclusion: Plastic surgeon is a fundamental character of a multidisciplinary team in the treatment of breast cancer, especially in large resection situations.
