Abstract
The invention discloses a fixed plate for acetabular rim anatomy, which is made of a pure titanium material. The fixed plate is F-shaped when unfolded, consists of a base, a first fin, a second fin, a third fin and a skirt. The base is a curved plate surface structure. The first fin arranged on the tail of the base is L-shaped. The third fin and the second fin are arranged on one side of a convex arc side on the head of the base in order from front to back. The skirt is a curved plate surface structure. The cross section of the skirt is wedge-shaped. The convex arc side on the skirt is connected with a concave arc side on the base. A plurality of screw holes are arranged on the fixed plate for acetabular rim anatomy. The fixed plate is characterized by simple surgical approach, small surgical trauma, easy fracture reduction, ideal fixed effect, firm fixed face and can achieve anatomical reduction with respect to complex acetabular fractures such as a transverse acetabular fracture, a T-shaped fracture and an acetabular both-column fracture.
Description
Technical field
The present invention relates to orthopaedics implant pelvis abnormity fixing head field, particularly a kind of limbus of acetabulum is dissected fixing head.
Background technology
Pelvis, fracture of acetabulum are caused that by the high-energy wound fracture of acetabulum of displacement causes femoral head cartilage and the non-concentric disc of cartilago acetabularis to cause mismatching.Cause each acetabular bone contact area of femoral head significantly to reduce,, bear a heavy burden and to cause the articular cartilage rapid damage and cause the generation of traumatic arthritis, the quick wear-out failure of femoral head if fracture of acetabulum heals under the displacement situation.The acetabular bone shape is just as the hemispherical nest, fall horseshoe-shaped articular surface round no articular surface acetabular fossa, part as innominate bone, it is positioned at ilium, the interface point of ischium and pubis, these three cartilages merge the last innominate bone that forms, and the orthopedist is divided into acetabular anterior column and rear pillar according to these characteristics with acetabular bone and innominate bone, and acetabular anterior column comprises crista iliaca, ilium sour jujube, the preceding half-sum superior ramus of pubis of acetabular bone.The acetabular bone rear pillar partly is made of ischium, comprises the ischium head, little incisura, and acetabular bone later half and tetragonal big and ischial tuberosity, the notion of post is used for the fracture of acetabulum typing before and after the acetabular bone, is classification of fracture, operative approach and internal fixation core are discussed.
The acetabular bone therapeutic purposes are to recover the acetabular bone anatomical shape, and contact area and intra-articular pressure distribute, and recover acetabular bone and capital concentric circular coupling, especially acetabular bone and push up, and it supports femoral head nodal section heavy burden part.The tetragon body is the medial wall of acetabular bone, forms the true pelvis lateral surface, and iliopubic eminence is the front pillar part that is located immediately at the femoral head top.Tetragon body and iliopubic eminence all than thin and proximal femur head, have limited this regional internal fixation type.
It is to give strong internal fixation again after losing the capable anatomical reduction of the forward and backward post of successional acetabular bone that fracture of acetabulum is cut multiple internal fixation, conducts each to functions such as capital containings to recover its mechanics.The bone operation of fracture of acetabulum of a success needs good making of each suitable internal fixation of surgical exposure to select.The different internal fixation methods of fracture of acetabulum are advanced comparison, and the whole bag of tricks does not have significant difference, and use at present double steel plate or a block plate in conjunction with lag screw fixedly acetabular bone still be the most frequently used method, the fixed effect that resets is undesirable.
For acetabular bone transverse fracture, intercondylar fracture and twin columns this quasi-complexity fracture of acetabulum of fracturing, the operative approach complexity, operation wound is big, the reduction of the fracture is difficult, use at present two steel pull or a block plate in conjunction with lag screw fixedly acetabular bone to exist fixed effect undesirable, usually can not reach the unstable weak point of anatomical reduction and stationary plane, influence patient's function of joint in the future.
Summary of the invention
The objective of the invention is at present when generation acetabular bone transverse fracture, intercondylar fracture and twin columns are fractured this quasi-complexity fracture of acetabulum, adopt two steel pull or a block plate to be used for fixing the existing fixed effect of acetabular bone in conjunction with lag screw undesirable, can not reach anatomical reduction and fixedly secure face and ring the weak point of function of joint in the future, provide that a kind of operative approach is simple, operation wound is little, the reduction of the fracture is easy, the fixed effect ideal can reach the firm limbus of acetabulum of anatomical reduction and stationary plane and dissect fixing head.
The technical solution used in the present invention is finished in the following way: a kind of limbus of acetabulum is dissected fixing head, and this limbus of acetabulum is dissected and is F shape when fixing head launches, and this limbus of acetabulum is dissected fixing head and is made up of matrix, fin one, fin two, fin three and shirt rim; Matrix is the arc curved-surface structure, is provided with screw hole one on matrix; Fin one is L-shaped, and fin one is located at the afterbody of matrix, and the width of fin one is less than the width of matrix, one side the aliging of the convex arc side on the side on the fin one and the matrix, the head of fin one is a circular arc, is provided with screw hole one at fin one; Fin three and fin two are located at one side of the head convex arc side of matrix successively by vertical order, the head of fin two and fin three is circular arc, is provided with screw hole two on fin two, is provided with screw hole three on fin three; The shirt rim is the arc curved-surface structure, and convex arc side on the shirt rim and the concave arc side on the matrix are joined, and are provided with oblique screw hole four in shirt rim and matrix joint, are provided with screw hole five on the shirt rim.
Dissect in the fixing head at above-mentioned limbus of acetabulum, described limbus of acetabulum is dissected fixing head and is adopted pure titanium (TA3) material to make.
Dissect in the fixing head at above-mentioned limbus of acetabulum, the cross section of described shirt rim is a wedge shape.
Dissect in the fixing head at above-mentioned limbus of acetabulum, dissect at limbus of acetabulum to be provided with on the fin one of fixing head and be provided with four screw holes one, shirt rim and matrix joint on two screw holes one, the matrix and be provided with and be provided with four screw holes five on four oblique screw holes four, the shirt rim.
During use, paste mutually with limbus of acetabulum the shirt rim that limbus of acetabulum of the present invention is dissected on the fixing head, and lock screw is with after four oblique screw holes four cooperate, fixedly the sclerite of limbus of acetabulum; The fin one that limbus of acetabulum of the present invention is dissected on the fixing head fits with ischium, and fin two and fin three that limbus of acetabulum of the present invention is dissected on the fixing head fit with acetabular bone top, and each adopts screw to fix.
The present invention has when fracturing this quasi-complexity fracture of acetabulum at acetabular bone transverse fracture, intercondylar fracture and twin columns, and operative approach is simple, operation wound is little, the reduction of the fracture is easy, and the fixed effect ideal can reach the firm characteristics of anatomical reduction and stationary plane.
