Abstract: The present disclosure discloses a fracture repair device realizing transition from mechanical fixation (association of osteosynthesis, AO) to biological fixation (biological osteosynthesis, BO), including: a bone repair instrument, wherein auxiliary components are arranged at positions, close to a repaired bone surface, of the bone repair instrument, and each auxiliary component is made of a degradable metal material or a composite material thereof or a degradable polymeric material. The device of the present disclosure only has the advantages of AO rigid mechanical fixation, but also can effectively improve the defects of bone disconnection, fixed segment osteoporosis, re-fracture after defixation, etc., frequently occurring under AO rigid mechanical fixation, realizing transition from mechanical fixation (association of osteosynthesis, AO) to biological fixation (biological osteosynthesis, BO) during bone fixation or repair.

Abstract: A bone trabecular structure, a prosthesis having the same, and a fabrication method thereof are provided. The bone trabecular structure includes a body configured to be a three-dimensional porous structure, which includes a plurality of struts and a plurality of pores formed by staggered connection of the plurality of struts. The pores are communicated with each other and have different average diameters. The average diameter of the pores ranges from 100 ?m to 400 ?m, and the porosity of the three-dimensional porous structure ranges from 50% to 80%. This bone trabecular structure facilitates postoperative bone ingrowth of a patient, and thus effectively improves the postoperative recovery effect of the patient.

Abstract: A toe joint prosthesis and a fabrication method thereof are provided. The toe joint prosthesis includes a first bone nail prosthesis and a second bone nail prosthesis hinged with the first bone nail prosthesis, the first bone nail prosthesis includes a first bone nail configured to be provided in a bone marrow cavity and a second bone nail connected with the first bone nail and located outside the bone marrow cavity, and the second bone nail is hinged with the second bone nail prosthesis. In particular, a three-dimensional porous structure layer is formed on an outer surface of the first bone nail and/or the second bone nail and/or the second bone nail prosthesis. An outer surface of the toe joint prosthesis are endowed with better bone ingrowth ability and bone crawling ability, thereby making the fixation of the toe joint prosthesis more stable.

Abstract: A bone trabecular fusion cage for implanting into an intervertebral disc is disclosed. The fusion cage includes a bone trabecular housing made of titanium alloy powder material with trabecular housing accommodation space therein. A side wall of the bone trabecular housing is provided with a plurality of pores, and sclerotin can grow into the bone trabecular housing through the pores to securely fix the bone trabecular fusion cage in the intervertebral disc; and a liner made of polyether-ether-ketone material and fixed in the accommodating space of the bone trabecular housing, wherein the polyether-ether-ketone liner gpores can provide good elastic modulus of bone. With the product of the present disclosure, bone implantation is not required, the patient recovers fast, and excellent fusion effect can be obtained.

Abstract: The present invention discloses a renovated titanium mesh used for repairing bone defects in knee joint replacement. The renovated titanium mesh (1) includes transverse ribs (2) for implanting the renovated titanium mesh into a human body and longitudinal ribs (3) for supporting the transverse ribs (2). The transverse ribs (2) and the longitudinal ribs (3) are crisscrossed to form the meshed renovated titanium mesh (1). In the renovated titanium mesh of the present invention, the meshed structure of the renovated titanium mesh can ensure the bone ingrowth of a patient, and the renovated titanium mesh can be cut to provide a high degree of matching for the patient and to thus satisfy the patient's demand; the renovated titanium mesh can better ensure the bone ingrowth of the patient and be advantageous for the later recovery of the patient.
