Description
本創作係關於一種脛骨固定裝置，特別係指一種脛骨近端後內側平台固定裝置。The present invention relates to a tibial fixation device, and in particular to a proximal posterior medial platform fixation device for the humerus.
人體各部位的骨骼形狀不盡相同且構造複雜，若發生骨折等傷害，在醫學上提供治療與復健的方式通常需依據受傷部位的骨骼結構而給予適當的治療，當骨折的部位靠近關節處時，較不適合使用石膏固定，則通常會採取骨板以及骨釘做為治療骨折的固定物。The bone shape of each part of the human body is different and the structure is complex. If a fracture or the like occurs, the medical treatment and rehabilitation method usually requires appropriate treatment according to the bone structure of the injured part. When the fracture is near the joint When it is less suitable for plaster fixation, bone plates and bone nails are usually used as fixes for the treatment of fractures.
以脛骨近端之骨折(又可稱為脛骨平台骨折)為例，當患者受到高能量之創傷，如車禍、強烈碰撞或者由高處墜落；或者低能量之創傷，如滑倒或摔倒，均可能造成脛骨平台的內側或外側受到波折而骨折，而脛骨後側平台受到衝擊而塌陷的情況亦不少見，因此需要以骨板將脛骨平台進行固定。Take the fracture of the proximal humerus (also known as the tibial plateau fracture) as an example. When a patient is traumatized by high energy, such as a car accident, a strong collision or falling from a height, or a low-energy trauma such as slipping or falling, It is possible that the medial or lateral aspect of the tibial plateau is fractured and fractured, and it is not uncommon for the posterior tibial plateau to be impacted and collapsed. Therefore, it is necessary to fix the tibial plateau with a bone plate.
傳統的脛骨平台後側的固定方式係先經由脛骨平台前外側間接先將骨骼復位後，再以用於脛骨平台前外側的骨板由先從脛骨平台前外側進入至後側，最後再進行間接固定，但此種方式卻常面臨無法確實將脛骨平台後側復位或固定，且手術時間耗時較長；手術後追蹤期間，後側及內側骨折處容易因固定力不足，導致移位。脛骨平台前內側路徑是最簡單的手術路徑，但是經由前內側路徑進行復位固定，內側骨板則因解剖位置，無法對後側骨折有效固定。若由脛骨平台後側路徑進入，則因脛骨平台後側的解剖構造繁複且神經血管與重要肌腱佈滿於此，增加手術的風險，加上特定用於脛骨平台後側之骨板也甚為少見，因此僅能利用使用於其他部位的骨板以將骨折的脛骨平台進行固定，但其骨板板形與骨面的吻合度可能較差，且植入後的穩定性和舒適度也較不好；另外，一般傳統所使用的骨板乃完全貼附於骨骼上，且依賴骨板與骨骼間的摩擦力以達固定之效果，但是由於此固定方式會對骨膜加壓造成骨折部位 的血液運輸不良，同時也會造成術後的骨折處的癒合緩慢或其他併發症的產生。另外，若患者患有骨質疏鬆，亦不推薦使用上述的手術固定方式。因此上述之術後恢復效果也會呈現不佳的狀況，所以需要開發出適用於脛骨近端後內側平台部位的相關骨板，以較簡單的前內側手術路徑，使受損的脛骨近端後內側平台得於術後有良好的恢復並避免再次塌陷。The fixation of the posterior side of the traditional tibial plateau is to first restore the bone through the anterior lateral aspect of the tibial plateau, and then the bone plate for the anterior aspect of the tibial plateau is firstly moved from the anterolateral aspect of the tibial plateau to the posterior side, and finally indirectly. Fixed, but this method often fails to reset or fix the posterior side of the tibial plateau, and the operation time is longer. During the postoperative follow-up period, the posterior and medial fractures are easily displaced due to insufficient fixation force. The anterior medial approach of the tibial plateau is the simplest surgical path, but is fixed and fixed via the anterior medial path, and the medial plate is unable to effectively fix the posterior fracture due to the anatomical location. If the posterior approach of the tibial plateau enters, the anatomical structure on the posterior side of the tibial plateau is complicated and the nerve vessels and important tendons are covered here, increasing the risk of surgery, and the bone plate specific to the posterior side of the tibial plateau is also Rarely, it is only possible to use the bone plate used in other parts to fix the fractured tibial plateau, but the plate shape of the bone plate may be inferior to the bone surface, and the stability and comfort after implantation are less. In addition, the bone plate generally used in the past is completely attached to the bone, and relies on the friction between the bone plate and the bone to achieve the fixation effect, but the fixation method may cause the periosteum to pressurize the fracture site. Poor blood transport can also result in slow healing or other complications at the postoperative fracture site. In addition, if the patient has osteoporosis, the above surgical fixation method is not recommended. Therefore, the above-mentioned postoperative recovery effect will also be inferior, so it is necessary to develop a relevant bone plate suitable for the posterior medial tibia of the humerus, with a simpler anterior medial surgical approach to the proximal humerus. The medial platform has a good recovery after surgery and avoids collapse again.
鑒於上述之問題，本創作之目的在於提供一種可貼合於骨骼上且係針對脛骨近端後內側平台塌陷或骨折之脛骨近端後內側平台固定裝置，使裝置的固定不需要過於依賴裝置與骨骼間的摩擦力，且可依靠裝置自身的交鎖結構達到固定效果。當本創作之裝置可不與骨骼接觸，而使裝置和骨骼之間具有空隙，亦可消除裝置對骨骼之加壓所造成可能的併發症狀(如病菌感染、骨折癒合緩慢、固定失敗等等)，同時可改善患部之血液運輸與骨膜的恢復與增長。在一實施例中，本創作之裝置又可應用於患有骨質疏鬆的患者身上。In view of the above problems, the purpose of the present invention is to provide a posterior medial posterior medial plate fixation device that can be attached to a bone and that is collapsed or fractured to the posterior medial tibia of the humerus, so that the fixation of the device does not need to rely too much on the device and The friction between the bones, and can rely on the device's own interlocking structure to achieve a fixed effect. When the device of the present invention is not in contact with the bone, and there is a gap between the device and the bone, the possible complications of the device pressing the bone (such as bacterial infection, slow fracture healing, fixation failure, etc.) may be eliminated. At the same time, it can improve the blood transport and periosteum recovery and growth of the affected part. In one embodiment, the device of the present invention is in turn applicable to patients suffering from osteoporosis.
本創作之另一目的在於提供一種脛骨近端後內側平台固定裝置，而上述的裝置可不需於事先預彎，但醫護人員可視病患脛骨近端後內側的大小及受損情況，而決定再彎折本裝置頭部與延伸部之角度並植入脛骨近端後內側平台以達固定之效果。Another object of the present invention is to provide a posterior medial platform fixation device for the proximal humerus, and the above device can be used without pre-bending, but the medical staff can determine the size and damage of the posterior medial aspect of the proximal humerus of the patient. The angle between the head of the device and the extension is bent and implanted into the posterior medial platform of the proximal tibia to achieve the effect of fixation.
另外，由於人站立時往往會產生一個向後力量並使其力量大多會偏向施力於脛骨近端後側平台(包括但不限於平台後內側或後外側)，因此當人體脛骨近端後內側平台受損並固定後，人體站立的行為往往會造成原來固定好的受損脛骨近端內側平台有再度塌陷的可能，因此本裝置乃提供一種力學支撐以保護受損的脛骨近端後內側平台不再塌陷。In addition, since the person tends to produce a backward force and tends to exert a force on the posterior side of the proximal humerus (including but not limited to the posterolateral or posterolateral side of the platform), the posterior medial platform of the proximal humerus After being damaged and fixed, the behavior of the human body tends to cause the proximal platform of the proximal fixed humerus to collapse again. Therefore, the device provides a mechanical support to protect the damaged posterior medial humerus. Collapse again.
