Tumour endoprostheses have facilitated limb-salvage procedures in primary bone and soft tissue sarcomas, and are increasingly being used in symptomatic metastases of the long bones. The objective of the present review was to analyse articles published over the last three years on tumour endoprostheses and to summarize current knowledge on this topic. The NCBI PubMed webpage was used to identify original articles published between January 2015 and April 2018 in journals with an impact factor in the top 25.9% of the respective category (orthopaedics, multidisciplinary sciences). The following search-terms were used: tumour endoprosthesis, advances tumour endoprosthesis, tumour megaprosthesis, prosthetic reconstruction AND tumour. We identified 347 original articles, of which 53 complied with the abovementioned criteria. Articles were categorized into (1) tumour endoprostheses in the shoulder girdle, (2) tumour endoprostheses in the proximal femur, (3) tumour endoprostheses of the knee region, (4) tumour endoprostheses in the pelvis, (5) (expandable) prostheses in children and (6) long-term results of tumour endoprostheses. The topics of interest covered by the selected studies largely matched with the main research questions stated at a consensus meeting, with survival outcome of orthopaedic implants being the most commonly raised research question. As many studies reported on the risk of deep infections, research in the future should also focus on potential preventive methods in endoprosthetic tumour reconstruction.

“…В свою очередь, трехфланцевые конструкции обладают наибольшим потенциалом в отношении увеличения зоны контакта со здоровой костью и обеспечения надежной фиксации в самых сложных ситуациях (дефекты типа 3В по Paprosky и pelvis discontinuity). при необходимости величина фланца может быть увеличена, а также получена дополнительная опора на крестцовую массу подвздошной кости с помощью специальных фиксирующих элементов типа «конус мороженого» [29,30]. по данным литературы, использование индивидуальных трехфланцевых вертлужных компонентов и конструкций типа «конуса мороженого» сопровождаются более высоким уровнем осложнений и неудовлетворительных результатов.…”

Introduction. The matter of the replacement of acetabular defects is becoming increasingly relevant today. In their clinic the authors used custom-made implants with trabecular coating for replacement of defects in the acetabulum where and when it was necessary to ensure extended fixation of the component. Purpose — to evaluate short-term clinical and functional outcomes, osteointegration of porous coated custom-made implants, the overall survival of structural components and to identify the causes of failures and complications. Materials and Methods. During the study the authors interviewed and evaluated radiographs of 48 patients operated from October 2015 to June 2018. The patients were interviewed before and after the surgery using the Oxford hip joint scale, quality of life EQ-5D and visual analogue pain scale. Radiographs were evaluated for a period of at least 12 months for the signs of osteointegration. Results. The average OHS scores increased from 14.9 (±7) to 37.6 (±7) (p<0.01). Quality of life according to the EQ-5D index increased from 0.2 (±0.2) to 0.7 (±0.2) (p<0.01). The average value by general health scales: before operations — 49 (±17) and 73 (±18) scores after surgeries (p<0.01). The average VAS pain score decreased from 73 (±10) to 19 (±19) points (p<0.01). Osteointegration was observed in 98 percent of cases. Migration of the implant with fracture of a flange was observed in one case. Conclusions. In the short-term follow up the use of custom-made implants significantly improves hip joint function and the patients’ life quality. Custom-made implants enable primary reliable fixation in case of complex acetabular defects. High rate of osteointegration is observed for custom-made implants with porous coating within at least 12 months. Longer follow-up is needed to evaluate long-term results.

“…In order to improve the implantation convenience and fixation stability, a lot of prostheses with different shapes and fixation methods has been reported, such as saddle endoprosthesis [1, 9], ice cream cone endoprosthesis [10, 11], modular hemipelvic endoprosthesis [2], and custom-made hemipelvic endoprosthesis [12–14]. Nevertheless, bone implant integration is still unsatisfying in long-term follow-up due to outdated interfacial processing of the endoprosthesis and poor matching between endoprosthesis and residual host bone.…”

BackgroundThis study is to describe the detailed design and surgical techniques of three-dimensional (3D)-printed custom-made endoprosthesis for hemipelvic tumorous bone defect.MethodsAccording to the pelvic tumor resection classification by Enneking and Dunham, the hemipelvis is divided into three zones including the ilium (P1), acetabulum (P2), and pubis and ischium (P3). Thirteen patients were included in this study. Of these, P1 and P2 were involved in three cases, while P1, P2, and P3 were involved in 10. Based on radiography data, 3D pelvic model was rebuilt, and virtual surgery was simulated. Different fixation methods were applied according to residual bone volume. Parameters of the first sacral (S1) vestibule, second sacral (S2) vestibule, the narrowest zone of superior pubic medullary cavity (NPSPMC), and the resected surface of superior pubic medullary cavity (RSSPMC) were selectively measured in various fixation methods. Model overlapping, feature simplifying, and size controlling were three basic steps during design procedure. Volume proportion of porous structure was determined according to estimated weight of resected specimen. Acetabular location, anteversion, and inclination were modulated. Screw diameter, direction, and combination were considered. The osteotomy guides and plastic models were used during surgery.ResultsOf 13 cases, after P1 resection, endoprostheses were fixed to sacra (8; 61.5%), ilia (3; 23.1%), and both (2; 15.4%). After P3 resection, endoprostheses were fixed to residual acetabulum (3; 23.1%), and residual pubis by stem (8; 61.5%) or “cap-like” structure (2; 15.4%). Mean area of the S1 vestibule, S2 vestibule, RSSPMC, and PSPMC were 327.9 (222.2 to 400), 131.7 (102.6 to 163.6), 200.5 (103.8 to 333.2), and 79.8 mm2 (40.4 to 126.2), respectively. Porous structure with 600 μm pore size and 70% porosity accounted for 68.8% (53.0 to 86.0) of the whole endoprosthesis on average. Mean acetabular anteversion and inclination were designed as 23.2° (20 to 25) and 42.4° (40 to 45). Median numbers of screws designed in the S1 vestibule was 5 (IQR, 4 to 6), in the S2 vestibule was 1 (IQR, 1 to 2), in the ilium was 5 (IQR, 2 to 6), and in the pubis was 1 (IQR, 1 to 1), while screws designed in the ischium was all 2. Median number of screws inserted in the S1 vestibule was 4 (IQR, 3 to 4), in the S2 vestibule was 1 (IQR, 1 to 1), in the ilium was 3 (IQR, 1 to 5), in the pubis was 1 (IQR, 0 to 1), and in the ischium was 1 (IQR, 1 to 1).ConclusionsThis study firstly presents detailed design and related surgical techniques of 3D-printed custom-made hemipelvic endoprosthesis reconstruction. Osseointegration is critical for long-term outcome and requires three design elements including interface connection, porous structure, and initial stability achieved by precise matching and proper fixation methods.
