As described above, in the Fracture of bone and joint for such as fracture of greater tuberosity of humerus, widely using steel plate and screw
Technique for fixing.By being fixed to screw, needles combined with tension band fixation for treatment fracture of greater tuberosity of humerus carry out biomechanics Research, both
Biomechanical strength no significant difference.But, screw, which is fixed, avoids the fracture of greater tuberosity of humerus bad for sclerotin condition from suffering from
Person, for sufferers of osteoporosis face, locking steel plate is fixed with more preferable biomechanical stability, but wound is big and needs second operation
Remove steel plate.Bioabsorbable interference screw fixation for treatment fracture of greater tuberosity of humerus takes out without second operation, but biomechanical strength is slightly weak,
Postoperative to need neck wrist strap to suspend suffering limb in midair, postoperative rehabilitation tempers delay, and what the patient that there are about 1.7% occurred postoperative wound infection can
Energy.Holdfast fixation for treatment fracture of greater tuberosity of humerus can be completed under arthroscope auxiliary, and the technology has that otch is small, soft tissue stripping
It is specious, the characteristics of wound is small from small.
Found during by the relatively advantage and disadvantage of various internal fixation materials：(1) often it is fracture when being fixed using hollow screw
The larger major tubercle fracture of block, but there is osteocomma when fixing broken risk is twisted by screw, due to it is fixed be major tubercle, supraspinous muscle
It is not fixed, is received or during outward turning in shoulder, the drawing strength of supraspinous muscle is stronger, easily causes the avulsion of bone piece, so adopting
The patient being screwed generally requires postoperative be fixed on outer exhibition position, it is impossible to carry out the rehabilitation training of early stage；(2) humerus is used
When near-end dissection locking steel plate is fixed, in order to which the major tubercle for fixing near-end is fractured, inevitably steel plate is moved up, near-end steel plate
Screw hole reluctantly fix bone piece, early postoperation take exercise when there is the separation of bone piece, part bone piece pulls back acromion by supraspinous muscle
Under, abduction muscular strength partial failure, while implants are inserted, the stripping to near-end normal structure is larger, and influence bone piece heals；(3) it is near
Holdfast, which fixes major tubercle fracture, over year turns into many athletic injury doctors selection fixed under opening or mirror.
In recent years it has been proposed that a kind of new fracture of greater tuberosity of humerus Morphologic classification.Fracture of greater tuberosity of humerus is divided into three
Type：Avulsion type fracture, splitting type fracture and compression-type fracture, as shown in Figure 1A to Fig. 1 C.Figure 1A to Fig. 1 C are to show
The figure of the fracture of greater tuberosity of humerus Morphologic classification of three types.For this new fracture of greater tuberosity of humerus Morphologic classification,
Present inventor devises a kind of new internal fixation material specifically designed for fracture of greater tuberosity of humerus, can dissect fixed big knot
Section, it is to avoid influence major tubercle blood supply, while supraspinous muscle can be fixed in the way of double fixation.In addition, meeting major tubercle dissection
The steel plate of form can fix major tubercle in gap under acromion, it is to avoid the destruction to deltoid muscle, reduce the risk of damage axillary nerve,
The interference of normal tissue is reduced to greatest extent.Meanwhile, the solution of the present invention can organically combine lockplate and holdfast technology
Get up, can skillfully be applied for being engaged in orthopaedic trauma doctor and sports medicine physician, and the more original holdfast of price
It is advantageous with locking steel plate, clinically can preferably it be promoted.
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description：
One side according to embodiments of the present invention is there is provided a kind of Bones and joints fixed plate, for the Bones and joints of fixed fracture,
The Bones and joints fixed plate includes：First end, is arranged at one end on the length direction of the Bones and joints fixed plate, and close in the bone
Save curved on the width of fixed plate；The second end, is arranged at the other end on the length direction of the Bones and joints fixed plate,
And it is curved on the width of the Bones and joints fixed plate；With, connecting portion, be arranged at the first end and the second end it
