Definitions
- Bone grafting with autografts involves application
- bone autografts are the “gold standard” of bone substitute materials, their use is limited, not always effective, and is associated with a high frequency of complications.
- One of the key drawbacks of their use and one of the reasons for their lack of effectiveness is the inability to accurately model them in shape and size of the replaced bone defect.
- the tight contact of any osteoplastic material over the entire surface of a bone defect or region of bone atrophy and complete immobilization are the primary canons of bone grafting [1].
- In conditions where autologous transplantation is not feasible or has proven to be doctors who are ineffective are forced to use distraction osteogenesis, prosthetics, or completely refuse this type of treatment, which significantly worsens the quality of life of patients.
- osteoplastic materials such as xeno- and allogeneic bone matrices of various processing options, calcium phosphate ceramics, bio-metals, organic acid polymers, as well as synthetic analogues or natural components of the bone matrix organic and mineral substances.
- they all have only osteoconductive effect, since they do not contain biologically active components.
- they are used only to replace bone defects of small size (volume), since they can only optimize reparative osteogenesis, but do not provide its induction [7].
- Products of this group in the form of personalized blocks to replace extended and (or) volume bone defects in clinical practice are practically not used.
- osteoplastic materials which can be divided into those containing growth factors (proteins), living cells, or gene constructs (nucleic acids). Osteoplastic materials with growth factors have a moderate osteoinductive effect, due to which they are able to activate reparative osteogenesis. However, growth factors are short-lived and short-distant, quickly disintegrate under conditions of inflammation in the surgical wound, and therefore the overall effectiveness of the products was insufficient to replace large-volume bone defects. In this regard, studies in which three-dimensional printing technologies were used to create osteoplastic materials of a given size and shape with growth factors are few, and in all of them the products were created in small size (about 1 cm 3 ). And even in this case, the results were far from optimal [8].
- Examples of another, more effective approach relate to the development of personalized tissue-engineered bone grafts.
- Using various technologies for creating carriers of a given size and shape researchers make personalized matrices, which are then combined with a living cell.
- carriers of a given size and shape are endowed with osteogenicity and, theoretically, are able to provide a pronounced induction of reparative osteogenesis.
- the realization by living cells, which are part of a personalized bone graft, of their therapeutic potential is limited by the need for oxygenation.
- With small sizes of such products up to 1 cm 3 )
- their effectiveness in comparison with the above categories of materials is shown in numerous studies. But when replacing extended (volumetric) bone defects, even with perfect modeling of the shape and size of the carrier for a renewable defect, an effective result cannot be achieved, since the cells inevitably die without adequate blood supply.
- the closest analogue of the claimed invention are gene-activated osteoplastic materials consisting of a carrier and nucleic acids - gene constructs encoding growth factors [9].
- Gene-activated osteoplastic material is a carrier-nucleic acid complex, the components of which are combined by various methods: due to the technology of chemical bonding [7], the use of auxiliary substances (for example, 5 gel biopolymers) [1 1], direct incorporation of nucleic acids acids in the composition of the carriers at the stage of matrix synthesis, etc.
- Such products have an osteoinductive effect, are not limited by the need for oxygenation, since they do not contain living cells.
- the severity of their osteoinductive effect and, as a result, the effectiveness of their use in the replacement of bone defects, according to many researchers are lower than in the case of tissue-engineered bone grafts. The reason is the low efficiency of transfection of the cells of the recipient bed with gene constructs, as well as the use of the “therapeutic power” of one-

- Fig. 7 Personalized gene-activated material with fixing elements that replaced the bone defect; 3 months after implantation: 1 - implant, 2 - bone regenerate. Histological micropreparation (staining: hematoxylin, eosin).
- the essence of the product we developed and the technology for its creation is to manufacture a personalized matrix from biocompatible and bioresorbable materials and to combine it with a biologically active component - gene constructs.
- a key aspect of the invention that distinguishes it from the closest analogue [9] is the use of three-dimensional printing technologies with the creation of a personalized product that is exact in shape and size to the recipient bed - the area of a bone defect or atrophy of bone tissue.
- the product is made in such a way that after implantation in the area of the recipient bed, the diastasis between the introduced material and the bone walls does not exceed 1 mm throughout.
- the achievement of personalized parameters is ensured by the use of three-dimensional printing technologies.
- An additional component of the product can be a fixing structure (reconstructive plates, screws, mini-plates, mini-screws, knitting needles, rods, etc.), which is included in the composition of the material even at the stage of its manufacture.
- a fixing structure reconstructive plates, screws, mini-plates, mini-screws, knitting needles, rods, etc.
- the presence of this component is mandatory in cases when a bioresorbable material with insufficient strength characteristics making it impossible to securely fix it in the recipient bed using standard methods (metal structures, etc.) as a carrier for gene structures is used.
- the technology for creating personalized gene-activated materials developed by us includes the following steps, the sequence of which can be changed: 1. Determination of the exact shape and size of a bone defect or area of bone atrophy. For this purpose, methods of radiation diagnostics, such as computed tomography, radiography, etc. can be used.
- the first stage relates to the planning of morphometric parameters of the manufactured product and requires the use of the same research methods that are used in the planning of surgical intervention.
- the most optimal option is computed tomography, which is an integral part of the diagnosis of skeletal bone pathology and provides data for planning bone reconstructive surgery.
- the data obtained during standard computed tomography can be used to simulate the shape and size of a bone defect and, accordingly, the shape and size of a personalized gene-activated implant in specialized software (for example, 3D Slicer, NHI, USA).
- a master file is generated for the 3D printer or any other device capable of manufacturing a three-dimensional implant with the specified parameters from the necessary bioresorbable material.
- a master file is generated for the 3D printer or any other device capable of manufacturing a three-dimensional implant with the specified parameters from the necessary bioresorbable material.
- calcium phosphates, hydroxyapatite, collagen, bio-metals, polymers of organic acids and others, including combinations thereof, can be the most optimal materials for the manufacture of the carrier.
- Aggregate the state and physical properties of bioresorbable materials selected to create personalized gene-activated implants can be any, which affects only a specific version of the technology of three-dimensional printing.
- Three-dimensional printing of the carrier matrix can be implemented in two fundamentally different ways. The first is to directly print media from the selected material. The second involves printing form-forming elements (from acceptable materials) with their subsequent use as forms for “casting” (synthesis) of the matrix of the carrier of a given shape and size.
- a critical step in creating a personalized gene-activated material is the combination of a carrier matrix and gene constructs (for example, plasmid DNA).
- a carrier matrix for example, plasmid DNA
- gene constructs for example, plasmid DNA
- the carrier is made of liquid (gel, sol, solution) or temporarily in the liquid phase material, then the gene constructs can be introduced into it before or during three-dimensional printing. If solid material is used (e.g. as
- gene constructs can be added as part of any gel material containing them.
- the simplest and most practicable way in most cases is to combine the manufactured personalized carrier material with the gene structures after three-dimensional printing. For this gene
- 25 structures in various concentrations in the form of a solution or as a part of a gel can be incubated under various conditions (temperature, exposure time, mechanical stress) with a “printed” carrier matrix.
- the gene constructs are combined with the carrier before or at the stage of its three-dimensional printing, then it is preferable to perform three-dimensional printing in in sterile conditions - clean rooms of classes A or B. If the gene structures are combined with the carrier after its manufacture, then three-dimensional printing can be performed in rooms of any class with subsequent sterilization of the resulting personalized carrier matrix and combined with the gene structures in sterile conditions.
- the successful result we obtained is related to the fact that the gene constructs of the gene-activated material of standard shape and size after implantation in the zone of an extended (volume) bone defect do not have direct contact with the cells of the recipient bed and do not reach the target cells. Moreover, the presence of diastasis between bone walls and gene-activated material of more than 1 mm causes the destruction of a greater number of released gene structures by blood convolution and inflammatory exudate, performing this space, and their rapid elimination. At the same time, the migration of resident cells is not active enough due to the loose adherence of the product to the walls of the bone defect. As a result, taking into account the already low efficiency of transfection of cells with gene constructs, especially in the case of plasmid DNA, nucleic acids do not enter cells in an amount sufficient to provide a therapeutic effect.
- the personalized gene-activated material has a tight fit with all surfaces of the recipient bed with a 5 “free space” of less than 1 mm. This creates the conditions, on the one hand, for faster and more massive migration of cells into the structure of the product, and on the other, to reduce the distance that gene structures travel on the way to target cells. The reduction of this distance, due to the lack of space between the gene-activated material and the walls of the bone defect, ensures the preservation of more gene structures, which is extremely important for the implementation of the therapeutic effect.
- the carrier material is fragile, fragile.
- fixation elements into the personalized gene-activated osteoplastic material even at the stage of carrier manufacturing.
- This can be implemented in two ways. The first consists in introducing a special core of metal or durable bioresorbable material into the interior of the fabricated matrix, which may contain holes for fixing elements (screws, mini-screws, microscrews, pins, knitting needles, etc.). At the same time, from the side from which the fixation of the product is planned, channels are formed in the carrier being manufactured, leading to the core (or core openings, if any).
- the second technological option consists in positioning the external locking system (for example, mini-plates with mini-screws) in a predetermined position and manufacturing a carrier of a given shape and size already on the fixing elements.
- the activated material may contain either internal (core), or external (in particular, mini-screws or mini-plates with mini-screws) fixation elements.
- the fixation elements should be selected.
- a three-dimensional bone model with an area of defect, atrophy, or pathological process can initially be made, the correction of which will entail the formation of a defect.
- This model should be delivered to the doctor planning the volume of surgical treatment.
- the doctor reproduces the planned manipulations (resection of the bone fragment, refreshment of the walls of the bone defect, etc.) and imposes fixation elements on the model - structures made of metals or durable bioresorbable materials, which will be used to immobilize bone fragments and a personal gene-activated implant.
- a model with fixation elements fixed to it in the correct position is used to calculate the morphometric parameters of a personalized gene-activated implant and its manufacture.
- the bone defect should be of maximum size, while allowing reliable fixation of the block without the use of metal structures in the field of implantation. Based on these criteria We have developed an experimental model of a cranial defect in rabbit bones with a diameter of 20 mm.
- the 3D Slicer program (NHI, USA) performed manual segmentation of the planned bone defect, the center of which was located in the projection of the sagittal suture at the same distance from the frontoparietal and parieto-occipital sutures.
- a three-dimensional printing of an octacalcium phosphate block was performed.
- the block had the appearance of a convex disk, 1, 3 mm thick, 20 mm in diameter and contained 17 perforations for decompression of the brain after replacement of the skull roof (Fig. 1, Fig. 2).
- VEGF vascular endothelial growth factor
- a personalized gene-activated implant was manufactured (Fig. 5).
- form-forming elements were made in which the metal-fixing products (miniplate and miniscrews) were positioned.
- a matrix carrier of tricalcium phosphate was synthesized, which exactly corresponds to the form parameters and contains fixing elements.
- the implant was combined with gene constructs (plasmid dna with vegf and sdf genes (encodes stromal cell growth factor)) according to the above protocol.
- the obtained personalized gene-activated product with “built-in” fixing elements was implanted into the defect of the bones of the leg of the rabbit, exactly corresponding to the parameters of the product (Fig. 6).
- the method we developed for creating personalized gene-activated material and its technological options allow us to manufacture medical devices that are effective for replacing bone defects, including long (bulk) ones.
