Description

一种用于髋关节假体周围骨折手术的人工股骨柄 One kind of artificial femoral fractures around the hip prosthesis for

技术领域 FIELD

[0001] 本发明涉及一种人体的内固定装置,具体涉及一种人体股骨骨折的固定装置。 [0001] The present invention relates to an apparatus for internal fixation of the human body, particularly relates to a device for fixing femoral fractures of the human body.

背景技术 Background technique

[0002] 近年来接受髋关节置换术(THA)及翻修术的病人不断增加,THA后高龄病人生存期延长及活动量增加,使得股骨假体周围骨折的发生率及复杂性随之增加。 [0002] In recent years, to accept the hip arthroplasty (THA) and revision surgery patients is increasing and prolong survival of elderly patients after THA and increase activity levels, making the incidence and complexity of femoral fractures around the prosthesis increases. 股骨假体周围骨折已成为瑞士病人全髋关节翻修的第三大原因。 Periprosthetic femoral fractures has become the third leading cause of Swiss patients with total hip arthroplasty is. 有报道表明,股骨假体周围骨折的发生率约占初次置换的1.1 %,翻修术后的4%,人工髋关节置换术中或术后发生的股骨假体周围骨折,由于假体柄的存在,一般的接骨板或髓内钉难以应用,而采用钢丝或箍带环扎或环扎加接骨板螺钉固定的方法,骨折再移位率高,难以取得满意的疗效,对于粉碎或螺旋形骨折更是如此。 Has been reported that, due to the presence of the prosthesis stem the incidence of periprosthetic femoral fractures account for about 1.1% of primary arthroplasty, revision 4% postoperative periprosthetic femoral hip replacement surgery or postoperative fracture, , general bone plate or an intramedullary nail is difficult to apply, while the use of cerclage wire or band or a method of fixing a bone plate screw ring ligation, and then displaced fracture rate, difficult to achieve satisfactory results, for the spiral fracture or pulverization even more so. 对于术后殷骨假体周围骨折,有学者采用牵引治疗,愈合率为66%~100%,但需长期卧床,并有高达20%的病例发生畸形愈合,因而多数学者主张手术治疗。 Yin surgery for bone around the prosthesis fractures, some scholars use of traction therapy, the healing rate of 66% to 100%, subject to long-term bed rest, and up to 20% of cases occur malunion, which most scholars advocate surgery. 由于股骨骨折区的髓腔被假体柄所占据,用于股骨骨折的常规内固定器如髓内钉、接骨板螺钉等,均因无法穿过被假体柄占据的髓腔而难以使用。 Since the canal femur fracture zone is occupied prosthesis, a femoral fracture fixation such as a conventional intramedullary nails, bone plates and screws, etc., are all occupied by the medullary cavity can not pass through the prosthesis difficult to use. 而只能使用钢丝或箍带环扎、螺钉斜穿、接骨板近侧以扎带固定远侧用螺钉固定等欠可靠的内固定方法,术后因固定不可靠而仍需长期卧床,且有很高的骨折再移位率。 But only using cerclage wire or band, cut through the screw, bone plate with proximal to the distal tie fixing screws and other less reliable fixation methods, fixation postoperative bedridden still unreliable, and there high fracture re-displacement rate. 难以取得满意的疗效,对于粉碎或螺旋形骨折更是如此。 It is difficult to obtain satisfactory results, or for crushing especially spiral fracture.
