Description
本創作創作係關於一種固定骨板，特別係指一種可適用於尺骨鷹嘴突骨折之固定骨板。 This creation is about a fixed bone plate, especially a fixed bone plate that can be applied to the olecranon fracture.
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.
以尺骨鷹嘴突骨折為例，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，均可能造成尺骨鷹嘴突受到波折而骨折，而尺骨鷹嘴突受到衝擊而塌陷的情況亦不少見，因此需要以骨板將尺骨鷹嘴突進行固定。 Take the ulnar olecranon fracture as an example. When a patient suffers from high-energy trauma, such as a car accident, strong collision or falling from a height, or a low-energy trauma such as slipping or falling, the olecranon may be fractured and fractured. It is not uncommon for the olecranon to be impacted and collapsed. Therefore, it is necessary to fix the olecranon by the bone plate.
另外，當尺骨鷹嘴突骨折時，一般傳統所使用之骨板的使用方式係先將尺骨鷹嘴突復位後，再將骨板完全貼附於尺骨鷹嘴突上，最後再以鎖定螺釘將骨板固定於尺骨鷹嘴突上，且依賴骨板與骨骼間的摩擦力以達固定之效果，但是現有之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，而目前的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，使手術後之骨折處恢復不佳。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。 In addition, when the olecranon fractures, the traditionally used bone plate is used to first reset the olecranon olecranon, then the bone plate is completely attached to the olecranon, and finally the bone plate is fixed with a locking screw. It is on the olecranon and depends on the friction between the bone plate and the bone to achieve the fixation effect. However, the existing plate shape and bone surface may be inferior, and the stability and comfort after implantation are also better. Not good, and the current fixation method will cause poor blood transport to the fracture site due to periosteal compression, and it will also cause slow healing or other complications of the postoperative fracture, which will make the fracture after the operation recover poorly. In addition, if the patient has osteoporosis, the above surgical fixation method is not recommended.
為解決上述之問題，現有的鎖定加壓接骨板(locking compression plate)依靠接骨板與螺釘的角穩定性及螺釘與骨皮質之間的把持力來實現對尺骨鷹嘴突骨折的固定。鎖定加壓接骨板的螺釘孔可由為動力加壓孔和圓錐形螺紋孔構成動力加壓孔可以使用標準螺釘實現軸向加壓，同時也能使拉力螺釘對移位的尺骨鷹嘴突骨折塊進行有效地加壓固定；而圓錐形螺紋孔內具有螺紋，可以和鎖定螺釘螺帽的螺紋鎖扣，達到轉移螺釘與接骨板之間力矩的作用，使縱 向的應力能夠傳遞至骨折端。鎖定加壓接骨板的使用同時也降低了對骨外膜血液運送的損傷，保護骨折端的血液運送情況；然而，鎖定加壓接骨板於術後仍然容易出現接骨板斷裂、尺骨鷹嘴突骨折不癒合與再次骨折的狀況。 In order to solve the above problems, the existing locking compression plate relies on the angular stability of the bone plate and the screw and the holding force between the screw and the cortical bone to achieve fixation of the olecranon fracture. The screw hole for locking the compression plate can be composed of a power compression hole and a conical thread hole. The power compression hole can be axially pressurized using a standard screw, and the lag screw can also be used for the displaced olecranon fracture block. Effectively pressurized and fixed; and the conical threaded hole has a thread inside, and can be screwed with the screw of the locking screw nut to achieve the torque between the transfer screw and the bone plate, so that the longitudinal The stress can be transmitted to the fracture end. The use of the locking compression plate also reduces the damage to the blood transport of the epicardium and protects the blood transport at the fracture end; however, the locking compression plate is still prone to fracture of the bone plate after surgery, and the ulnar olecranon fracture does not heal. And the condition of fracture again.
再者，骨頭關節面之解剖構造繁複且神經血管與重要肌腱佈滿於此，倘若患者之關節面骨折處受損程度較不嚴重，但上述之關節面卻又以骨板作較大面積之包覆，亦可能造成術後恢復效果也會呈現不佳的狀況，而骨板形狀亦無法因應患者骨折部位的嚴重程度進行調整，因此需要開發出可適用於固定尺骨鷹嘴突骨折的骨板，使受損的尺骨鷹嘴突骨折部位得於術後有良好的恢復，且可進一步改善先前使用之骨板(如一般傳統骨板、鎖定加壓接骨板等等)所產生的術後問題。 Furthermore, the anatomical structure of the bone articular surface is complicated and the nerve vessels and important tendons are covered here. If the fracture of the joint surface of the patient is less severe, the above-mentioned articular surface is made of a large area. Coiling may also cause poor recovery after surgery, and the shape of the bone plate cannot be adjusted according to the severity of the fracture site of the patient. Therefore, it is necessary to develop a bone plate suitable for fixing the fracture of the olecranon. The damaged olecranon fractures have a good recovery after surgery, and can further improve the postoperative problems caused by previously used bone plates (such as general traditional bone plates, locking compression plates, etc.).
鑒於上述之問題，本創作之目的在於提供一種尺骨鷹嘴突固定骨板，而本骨板亦適用於固定不同程度的尺骨鷹嘴突骨折且可完全依靠骨板自身的交鎖結構達到固定效果。本骨板可適用於固定不同程度之尺骨鷹嘴突骨折的最重要原因在於本骨板之形狀可提供尺骨鷹嘴突足夠的包覆，顯示本創作之骨板形狀可因應不同程度的尺骨鷹嘴突骨折。而當骨頭之關節及其鄰近部位破損嚴重時，本骨板得與關節面有較大面積之接觸並提供較佳之固定，使骨折塊不易移位。 In view of the above problems, the purpose of the present invention is to provide a ulnar olecranon fixed bone plate, and the bone plate is also suitable for fixing different degrees of ulnar olecranon fractures and can completely rely on the interlocking structure of the bone plate itself to achieve a fixation effect. The most important reason why the bone plate can be used to fix different degrees of olecranon olecranon fracture is that the shape of the bone plate can provide sufficient covering of the olecranon olecranon, indicating that the shape of the bone plate of the present invention can respond to different degrees of olecranon fracture. . When the joint of the bone and its adjacent parts are severely damaged, the bone plate has a large area of contact with the articular surface and provides better fixation, so that the fracture block is not easily displaced.
另一方面，本創作骨板可減少骨板與關節面之接觸面積並提供簡單的支持與固定，使骨板和關節面之間具有空隙，除可消除骨板對關節面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)，亦可改善患部之血液運輸與骨膜的恢復與增長。在另一實施例中，本創作之骨板又可應用於患有骨質疏鬆的患者身上。 On the other hand, the artificial bone plate can reduce the contact area between the bone plate and the articular surface and provide simple support and fixation, so that there is a gap between the bone plate and the articular surface, in addition to eliminating the pressure of the bone plate on the articular surface. Possible complications (such as bacterial infection, slow fracture healing, fixation failure, etc.) can also improve blood transport and periosteal recovery and growth in the affected area. In another embodiment, the bone plate of the present invention is in turn applicable to a patient suffering from osteoporosis.
