Description
Technical field
The utility model relates to the field of medical instrument technology, specifically, being a kind of tibial plateau external condyle fracture fixation
Novel "T"-shaped steel plate.
Background technique
Tibial plateau (tibial condyle) is two more flat faces that proximal tibia enlargement is formed, with external condyle phase in femur
Joint.Two condyles are separated in the intercondylar ridge that midline position is swelled.Medial side of tibial plateau condyle is larger, and articular surface recess, sclerotin is more
It is tough and tensile.Condylus lateralis tibiae is relatively small, and articular surface is slightly convex, and sclerotin is more loose.When by external force, entocondyle is mostly that monolith is split
Fractured bone folding, external condyle are mostly crushing, the collapsed fracture for involving articular surface.Normal adult has due to femur anatomical axis and tibial shaft axis
6 ° of valgus angle makes knee joint in state of slightly turning up, this is that outside Platform Fracture incidence is high-incidence compared with inside Platform Fracture
Anatomic factor.There is scholar to point out in fracture of tibial plateau in reported literature, simple outside condylar fracture accounts for 50%, and fractures
Form is mostly that splitting, articular step-off or both exist simultaneously.
After simple outside Platform Fracture be used as on the outside of Platform Fracture specific type one kind, incidence be once considered as compared with
Low.Understanding with the extensive use of CT scan Imaging Technology, " three columns are theoretical " and " four-quadrant is theoretical " is goed deep into.With rear
The treatment of outside Platform Fracture is increasingly becoming the research hotspot of orthopaedic trauma.Fracture usually by under knee sprung state by axial direction
Violence causes, and can individually occur, and also other combinable quadrants occur simultaneously.In general, low energy damage causes, outer after isolating
The fracture of side quadrant；The damage of high energy often merges the fracture of other quadrants.At present for rear outside Platform Fracture appear and it is solid
Determining mode has as many as more than 10.But which kind of therapeutic modality is best, does not reach an agreement yet, and there are biggish disputes.
External condyle surrounding anatomical structures are complicated after tibial plateau and position exists deeply, are directly appearing and reset is stranded there are many
It is difficult.At present about rear outside Platform Fracture therapeutic modality existing more than 10, but in view of the special classification of fracture of rear outside platform, multiple
Miscellaneous anatomical structure, to this type fractures, domestic and foreign scholars not yet reach common understanding, and there are biggish disputes.Outside before traditional
Approach simply, conveniently, safely, but can not completely appear rear outside platform, and replacement and fixation is ineffective, and clinic is less to answer
With.Medial approach, afterwards center approach, improvement posterolateral approach, the satisfaction of neck of fibula osteotomy fixed effect afterwards, but related in art
And the dissection of blood vessel or nerve, technical level require the disadvantages of high, tissue damage is big, operating time is long.Approach, improvement are hit exactly afterwards
Posterolateral approach appear limited, influence steel plate place and the reduction of the fracture, if merge other quadrants fracture, other hands need to be combined
Art approach expands tissue damage.Neck of fibula osteotomy, appears and replacement and fixation good results, but truncation fibula, bone are needed in art
Head of fibula fixation is gone back again after folding replacement and fixation, increases the risk of new wound and osteotomy disunion.The reports such as Frosch
The double spatium intermusculare approaches of the single notch in outside afterwards, in not all right fibula osteotomy, perfection appears and fixes preceding outside and rear outside
Two quadrants.But it needs to remove surrounding soft tissue extensively in art, has and destroy the risk that Peripheral blood supplies.In addition, at present various rear sides (after
Outside) if the steel plate placed needs to take out, have the shortcomings that the secondary taking-up of cicatricial tissue hyperplasia is difficult.Therefore, for such bone
It is orthopaedic trauma area research hot spot that folding, which explores one kind to appear safe ready, fix simple and effective modus operandi,.
For the deficiency of existing modus operandi, there is scholar to propose the fixation theory of " horizontal band-like steel plate ".Horizontal band-like steel
The appearance of plate (horizontal belt plate) be after Anteroposterior aproach replacement and fixation lateral tibial plateau fracture become can
Energy.Horizontal band-like steel plate was proposed by Colombia doctor Berm ú dez etc. in 2008 earliest.Hereafter other scholars propose in succession
" edge steel plate " (rim plate, marginal plate), " cortex wrapping steel plate " (cortical containment
Plate), the concepts such as " hoop iron plate " (hoop plate).
They by using 1/3 cast plate of clinical existing 3.5mm series, reconstruction plate, 2.7mm series of plates and
Distal radius T shape lock steel plate of 3.5mm series etc. carries out bending moulding according to tibial plateau edge contour form in art, into
And platform is wrapped." horizontal band-like steel plate " used in clinic is only through the platform after bending to fracture at present
Articular surface provides package, gathers fixation, effectively cannot be supported fixation to metaphysis.It is carried out to the fracture to metaphysis
Good fixation, is generally required to merge metaphysis is fixed using the steel plate of its alloytype, and implants quantity is increased, and expands wound
One's intention as revealed in what one says danger, making patients' financial burden.
Chinese patent application: CN202505471U discloses outside locking steel plate after a kind of tibial plateau, including steel plate body,
Steel plate body is made of lockplate on the outside of tibial plateau and the interior plate being connected with lockplate on the outside of tibial plateau；Tibial plateau
Outside lockplate is equipped with lock hole, and interior plate is equipped with screw hole.
Chinese patent application: CN207707999U discloses a kind of dissection armor plate of outside condylar fracture after tibial plateau, packet
Include: a steel plate, steel plate include a main part and a row part, and main part forms one end higher than the other end along the long side direction
Bending, between main part and row part formed a smooth corner, and corner be 100 degree；Row part is shin
Anatomical form arcuate structure in the head of fibula of outside before bone platform；Main part is anatomical form straight configuration on the outside of tibial plateau is gone forward；
Main part and row part offer several perforative holes.
Therefore, for above-mentioned deficiency, inventor devises condylar fracture on the outside of a kind of tibial plateau of the utility model
Fixed novel "T"-shaped steel plate, inventor is directed to 2 isolated rear outside Platform Fractures within 2016, using remote by 3.5mm radius
The horizontal band-like steel plate of end palmar T steel plate (5 hole of trailing arm, 3 hole of transverse arm) transformation is fixed, and performs the operation simple and quick, faces
Bed excellent effect.Attending physician makes the outside Platform Fracture seriously crushed above T shape and (or) L shape raft supporting steel plate
With 1/4 tubular steel plate being horizontally arranged after bending, wrapping fixation is carried out to outside before tibial plateau.Giordano in 2017 etc. is situated between
The patient of the double postartis comminuted fracturees of 1 tibial plateau that continued wraps articular surface (hoop iron plate) from rear using 1/3 cast steel plate,
The successful experience for cooperating supporting plate to be treated again.The utility model design steel plate can cut randomly, bending, moulding,
The entire external condyle platform for including rear outside Platform Fracture is fixed, and may be implemented when fixed to broken fracture platform
The interior receipts power for providing wrapping, gathering enhances fracture fixation intensity.It is solid about condylar fracture on the outside of a kind of tibial plateau of the utility model
Fixed novel "T"-shaped steel plate yet there are no report.
