Abstract
The utility model relates to a tibial plateau posterior-lateral bone fracture plate, which belongs to the field of the medical instrument and is mainly used for tibial plateau high-energy damage accompanied with posterior-lateral bone fracture collapse. The tibial plateau posterior-lateral bone fracture plate consists of a tibial plateau posterior-lateral bone fracture plate (1), a phi 3.5 locking screw (2) and phi 3.5 bulb needles (3). In the surgery operation process, a posterior-lateral surgery surgical incision is cut, important blood vessels and nerves can be protected, the bone fracture is exposed, a joint is reset, a surgery position is cleaned, the specification and the amount of the required tibial plateau posterior-lateral bone fracture plate and the screw in the surgery are determined, the surgery is implemented, and the tibial plateau posterior-lateral bone fracture plate (1), the phi 3.5 locking screw (2) and the phi 3.5 bulb needles (3) are implanted and fixedly arranged on the position required by the surgery so as to realize the surgery purpose.
Description
Technical field
This utility model relates to outside blade plate after a kind of tibial plateau, belongs to medical instruments field, is applicable to tibial plateau complicated fracture.
Background technology
Fracture of the tibial plateau refers to and occurs in the fracture that tibial tubercle comprises tibia condyle above, and it accounts for 4.83% of all fracture.Due to the high correlation with motion and vehicle accident, the incidence rate of fracture of the tibial plateau raises year by year.Up to now, in the implant of fracture of the tibial plateau, the combination of proximal tibia outer side steel plates and inner side blade plate is still the standard combination configuration for the treatment of fracture of the tibial plateau both at home and abroad, it is domestic that rear inner side blade plate only has a YouAO company just in the recent period, to drop into, but follow the increasing of high-energy damage, with tibial plateau rear side, fracture, the case of subsiding is more and more, after outstanding, outside is main, and both at home and abroad all without the ripe therapeutic scheme of specialty, in this case, the director Wang Xiaoning Yu Wo company cooperation of PLA General Hospital the first Affiliated Hospital (Yuan304 hospital), developed " outside blade plate after tibial plateau " product.
Up to the present, to the case with outside articular step-off after tibial plateau, due to most doctors being unfamiliar with and lacking the fixation device matching with it for rear outside operative approach, substantially before adopting clinically, after the Indirect reduction of outside, be aided with outer side steel plates indirect fixing from front to back.Above therapeutic scheme is simple to operate, but has open defect: the one, and Indirect reduction cannot confirm with any objective form (direct-view or fluoroscopy during operation) in practical operation; The 2nd, even if can partial reset, due to front to after screw placement cannot play anti-skidding and support the effect of rear sclerite, postoperative go down on one's knees to be bound to cause rapidly while taking exercise reset and lose, cause joint unstability, long-term pain.The report of the long term follow-up of large clinical case shows successively in recent years: to this type fracture, three aspects of incidence rate of the CT assessment after surgery of conventional reset fixing means, convalescence pain Assessment and traumatic arthritis at a specified future date demonstrate result gloomy.The tibial plateau " three posts are theoretical " proposing from wind along with Shanghai sieve Liu Yuan be that International Academic is praised highly and approves rapidly, orthopaedic trauma field to tibial plateau after outside the processing referred new height gradually of articular surface.The sclerite of mixed lateral column after repeatedly adopting the operative incision of designed, designed in director's Wang Xiaoning clinical operation process and using the T-shaped blade plate processing of distal radius tibial plateau, clinical effectiveness obviously improves.But because anatomic form differs greatly, design concept is different, in art, need by T-shaped blade plate repeatedly moulding, block, repair, polish.Incur loss through delay operating time, reduced blade plate intensity, easily caused lock hole deformation.So we have designed this kind of product according to the posterolateral peculiar anatomical structure of tibial plateau, to adapt to this type of patient's treatment.
Summary of the invention
The purpose of this utility model is: provide a kind of and have that wound is little, therapeutic effect obviously, outside blade plate after the tibial plateau of novel structure.The technical solution of the utility model is as follows:
After tibial plateau outside blade plate by tibial plateau after outside blade plate (1), Φ 3.5 lock screw (2), Φ 3.5 buttons (3) form, it is characterized in that: after tibial plateau, outside blade plate (1) thickness is 1.6mm, head width is 17.3mm, overall length is 60mm, about minute, head has three Φ 3.5 screw hole to be down Chinese character pin-shaped distribution, upper two screw hole and articular surface be downward 3 ° of angulations all, inboard aperture is parallel with sagittal plane, apertura lateralis and sagittal plane are 15 ° of abductions, the lock hole in below is all parallel with sagittal plane with articular surface, the below of three Φ 3.5 screw hole, 4.2 * 8.5 long slot bores, with realization, squeezing into Φ 3.5 buttons (3) compresses articular step-off fragment and can upper and lower micro-distance adjust to correct position, all screw holes require all implantable Φ 3.5 buttons (3).
The feature of Φ 3.5 lock screw of the present utility model (2) is that ailhead has 20 ° of taper threads, rivet nut entire body screw thread; Φ 3.5 buttons (3) are ailhead sphere, rivet nut entire body screw thread.
By preoperative imaging examination; patient adopts lateral position or floating position; outer arcuate otch after row, protection common peroneal nerve, cut-off parts musculus soleus starting point; dissociate and lay special stress on protecting after the shin of inner side under arteriovenous and articular surface the anterior tibial artery at 5cm place and return and prop up; now can clear rear outer side seam piece and the articular surface of appearing of subperiosteum, the lower reseting fracture of direct-view, implants after tibial plateau outboard dedicated blade plate and confirms placement location with fluoroscopy during operation; close otch, complete operation.Owing to can reaching direct strong support, anti-skidding fixing, postoperative next day, patient can go down on one's knees to the active-passive rehabilitation training of 90 degree, had greatly alleviated pain, had shortened recovery time.
Operation in the past, owing to there is no outside after specialty treatment tibial plateau, do not follow the blade plate of articular step-off case, in addition most clinicists are for being unfamiliar with of rear outside operative approach, and clinically before basic employing after the Indirect reduction of outside, are aided with from front to back indirectly fixing of outer side steel plates.The open defects such as this scheme existence resets uncertain, fixing insecure, resets and loses soon, and pain is obvious, and long term complication is many.
Outside blade plate after tibial plateau of the present utility model, specific aim has been improved in above-mentioned case without special-purpose blade plate implantation, and with outer side steel plates, is indirectly used in conjunction with reluctantly the bad result clinical near, at a specified future date causing; After this tibial plateau, outside blade plate adopts the manufacture of titanium material, and good biocompatibility, does not reject, favourable post-operative recovery.
This utility model adopts novel project organization, and simple to operate, practical, processing cost is low, is suitable for Orthopedic Clinical and applies.
