Abstract
The utility model relates to a proximal tibia platform rear side pressurization locking type steel plate. A fixing steel plate is arranged, and the upper end of the fixing steel plate is provided with a pressurizing head in a protruding manner. The pressurizing head is inclined and bended towards the front end of the fixing steel plate and is provided with at least one screwing fixation hole. The fixing steel plate is provided with at least one side screwing fixation hole towards each of the two lateral sides and at least one lower screwing fixation hole towards the lower side. The screwing fixation hole, the side screwing fixation hole, and the lower screwing fixation hole all allow screwing fixation elements to screw therein. In this way, a bone fragment avulsed and translocated by the posterior cruciate ligament in the rear side of the proximal tibia can be concretely pressed and positioned so that the bone fragment is enabled to be truly recombined with the tibia and recover. Not only can the convenience that medical personnel performs the recovering and positioning of the bone avulsed and broken in the rear side of the proximal tibia of a patient be increased, but also the case that the bone after recovery affects the action capability of the patient can be prevented. Thus, the steel plate is improved in practical efficacy characteristic from the aspect of overall implementation and utilization.
Description
Technical field
This utility model is relevant for a kind of proximal tibial platform rear side pressuring locking type steel plate, refer in particular to a kind of bone fragments of posterior cruciate ligament institute avulsion displacement that proximal tibia rear side can be subject to and really press location, this bone fragments can again be replied with the certain combination of tibia, can not only increase skeleton that medical personnel rupture damaged by sufferer proximal tibia rear side and reply the convenience of location, and more can prevent from having after bone restoration and affect the situation of sufferer ability to act and occur, and use its whole execution the proximal tibial platform rear side pressuring locking type steel plate that more increases practical effect characteristic.
Background technology
Partes corporis humani position has many skeletons, and it can be used as the support of health, supports soft tissue and organ, and protection internal prevent from coming to harm, and as the attachment point of the most of muscle of human body, physical shapes and stance is maintained.
Wherein, knee joint is joint maximum in health, and it is comprised of several bone of Thigh bone, tibia, fibula and patella [being commonly called as Patella], is supporting the weight of human body, the flexing of knee and stretching.Between Thigh bone and tibia, there is semilunar cartilage, thick about 3-9 millimeter, the function of this cartilage, has absorbed the impact from external force exactly, and makes the activity of carrying out that knee joint can be round and smooth, is equivalent to the function of back cushion; In addition, in knee joint, still have several ligaments to be responsible for kneed stable and motion, anterior cruciate ligament (ACL) prevents that tibia reach, posterior cruciate ligament (PCL) from preventing from moving after tibia, lateral collateral ligament (LCL) prevents from turning in knee, medial collateral ligament (MCL) prevents that knee from turning up.
And the size of human body knee joint and kinetic characteristic thereof vary with each individual, simultaneously can be because of factors such as injured, disease, aging and operations and change; Knee Trauma is one of modal sport injury, every from simply walking, jogging, and to fierce contact movement (as foot, basketball, judo etc.), the situation of knee joint injury all may occur.
Generally be common in the fracture phenomenon that kneed tibia place rear side is caused by the factors such as external force collision, due to posterior cruciate ligament bottom and the link of tibia rear side upper end, once make this position produce fracture, posterior cruciate ligament can be by the up pull-up of ruptured damaged bone fragments (referring to Fig. 5 tibia rear side upper end ruptures shown in damage state based schematic diagram), if now press location without the bone fragments that suitably fixture will be shifted by the avulsion of posterior cruciate ligament institute, cannot allow it reset in time fixing, often can affect the reply situation of skeleton, cause in the future and often need carry out separately posterior cruciate ligament reconstruction operations, increase is to disorganization, have influence on even sufferer active state backward.
So inventor adheres to the abundant of these relevant industries for many years and designs and develops and actual fabrication experience, is studied improvement for existing structure again, provide a kind of proximal tibial platform rear side pressuring locking type steel plate, to reaching the object of better practical value.
