Background: Electron beam melting rapid prototyping technology, has the characteristic of shaping precisely and complexly, is a new type of rapid prototyping technology using metal powder. Now, it has shown unique advantages in the fields of aerospace, automotive and medical implant equipments. Objective: To explore the properties of the product, the customization ability of orthopedic implants through electron beam melting rapid prototyping, especially the ability of inducing bone ingrowth. Methods: We retrieved PubMed Database, China Journal Full-text Database, and China National Knowledge Infrastructure, as well as Dongfang Daily, World Science, and Chinese Journal of Orthopaedics by hand, and assembly documents in Chinese and English. Retrieval time was up to September 2013. Inclusion criteria: {circled digit one} articles concerning electron beam melting rapid prototyping technology; {circled digit two} articles addressing surgical implants. A total of 50 articles were included. Results and Conclusion: Electron beam melting state Ti6Al4V orthopedic implant has a good comprehensive performance, since the three-dimensional porous structure via electron beam melting rapid prototyping, which has a characteristic of customization, can induce bone ingrowth.

A spinous metal granule (1) is provided. The outline of the spinous metal granule (1) is spherical, cylindrical or polyhedral and is 2 to 15mm in size and the spinous metal granule (1) is provided with spinous structure (2) like a urchin or dentrite. When in use, an appropriate number of spinous metal granules (1) of appropriate size and shape are selected by a doctor to be mixed and stirred with the autogenous or allogeneic broken bone granule and bone paste (3) of a patient to form a mixed filler, which is filled in the bone defect and is pressed and tamped to be initially stabilized. In the recovery process after an operation, the surrounding sclerotins and the bone paste (3) and broken granules surrounding the spinous metal granule (1) are fused to grow into a whole to form a relatively stable and biologically active support structure. Meanwhile, such support structure can further stimulate the surrounding blood supply to promote the repairing of the damaged cartilage.

A fusion spine internal fixation screw comprises a screw cap section (20) and a bone joint section (10) connected with the screw cap section (20), wherein the bone joint section (10) comprises a solid part (12) and a porous fusion part (11) fixedly arranged on the surface of the solid part (12); and the porous fusion part (11) is provided with a porous structure inosculated with spine sclerotins. The porous fusion part (11) of the bone joint section (10) of the fusion spine internal fixation screw is of a porous structure, which can promote bone cells to grow therein to fuse sclerotins with the screw after the fusion spine internal fixation screw is implanted into the sclerotins, so as to finally form a bone fusion state, which can effectively prevent the fusion spine internal fixation screw from being loosened or unscrewed in a long term.

A fusion prosthesis (1) is provided, which is arranged between a first bone structure (2) and a second bone structure (3) to replace bone structure between the first and second bone structures (2, 3) and comprises a prosthesis body (10) and prosthesis fusion surfaces (20, 60) on the prosthesis body (10), wherein the prosthesis fusion surfaces (20, 60) are inosculated with at least one of the first and second bone structures (2, 3) and are provided with microporous structures (30). The prosthesis body (1) is a metal implant of equal size manufactured according to the tomography data, such as CT, MRI, and UCT, of a patient. The prosthesis fusion surfaces (20, 60) are constructed according to the replaced bone structures and are well inosculated with at least one of the first and second bone structures (2, 3). The microporous structures (30) on the prosthesis fusion surfaces (20, 60) are favorable for the crawling and ingrowth of bone cells. After an operation, the prosthesis fusion surfaces (20, 60) of the prosthesis body (1) will be fused with the bone articular surface of at least one of the first and second bone structures (2, 3) to achieve the long-term stability.
