Rate is also incremented by therewith.And different degrees of acetabular bone defect is clinically very common, it is to determine that the biology of acetabular defects, which is rebuild,
The key of hip revision success or not.
It in recent years, is the main policies for handling serious acetabular bone defect using metal acetabular cup joint porous metals cushion block, and
Other materials is compared, due to porous metals porosity with higher, be conducive to freshman bone tissue grow into and it is long-term
Biological fixation, and porous metals and spongiosa bone interface have higher coefficient of friction, therefore shear strength is bigger.It is more simultaneously
Mesoporous metal has lower elasticity modulus compared to other metal prostheses, this can provide good biomethanics ring for new bone formation
Border.
However, the acetabulum reconstruction prosthese higher cost for being suitable for filling acetabular bone bottom bone defect existing at present, and deposit
It is leaned on being not fixed firmly, stops mortar cup fixing screws, the problems such as model is single.
Summary of the invention
For this purpose, an object of the present invention is to provide a kind of collar plate shapes that can be used for the reconstruction of acetabular bone bottom bone defect biology
Bone trabecula metal acetabulum rebuilds prosthese, is not fixed firmly with to solve existing prosthese and is leaned on, and stops mortar cup fixing screws, and model is single etc. asks
Topic.
The present invention provides a kind of collar plate shape bone trabecula metal acetabulums to rebuild prosthese, and the prosthese is the metal knot of collar plate shape
Structure, the prosthese have trabecular bone structure, have hole on the surface of the prosthese, and be provided on the side of the prosthese
Notch.
Collar plate shape bone trabecula metal acetabulum provided by the invention rebuild prosthese be suitable for acetabular bone bottom bone defect filling and
Biology is rebuild, and the rough surface of prosthese has good porosity and trabecular bone structure, is suitble to growing into for bone tissue, is made prosthese
It is integrated well with bone tissue, biology well can be carried out to acetabular bone bottom bone defect and is rebuild, especially in prosthese
It is provided with the notch for allowing mortar cup fixing screws to pass through on side, mortar cup fixing screws will not be caused to stop.
Further, the material of the prosthese be medical titanium alloy, medical cobalt alloy, medical tantalum alloy, medical magnesium alloy,
Medical stainless steel, medical niobium alloy or medical zircaloy.
Further, the diameter of the prosthese is 20mm-80mm, with a thickness of 1mm-10mm.
Further, the diameter of the notch is 1mm-10mm.
Further, the notch has 1-4.
Further, the porosity of the hole on the surface of the prosthese is 30%-90%, aperture 50um-1000um.
Further, the coefficient of friction between the surface and cancellous bone of the prosthese is 0.1-0.3.
Further, the elasticity modulus of the prosthese is 0.1Gpa-20Gpa.
Further, the micro- rivet of self-stabilization structure is connected on the back side of the prosthese.
Further, micro- rivet has 1-4.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
Detailed description of the invention
Fig. 1 is that a kind of collar plate shape bone trabecula metal acetabulum of the embodiment of the present invention rebuilds the structural schematic diagram of prosthese.
It is attached in the figure, it is marked as
