Description
Technical field
The present invention relates to a kind of inner fixing device of human body, be specifically related to a kind of human femur under loading fixation of fractures device.
Background technology
The patient who accepts hip replacement (THA) and overhaul technology in recent years constantly increases, behind the THA advanced age patient's survival period and activity increase, make the incidence rate of femoral prosthesis surrounding fracture and complexity increase thereupon.The femoral prosthesis surrounding fracture has become the third-largest reason that Switzerland's patient's full hip-joint is overhauled.Have report to show, the incidence rate of femoral prosthesis surrounding fracture accounts for first metathetical 1.1%, 4% behind the overhaul technology; In the Replacement of Hip Joint or the femoral prosthesis surrounding fracture that takes place of postoperative, because the existence of prosthese handle, general blade plate or intramedullary pin are difficult to use; Add blade plate screw fixed method and adopt steel wire or band ring to prick or encircle to prick; The fracture redisplacement rate is high, is difficult to obtain satisfied curative effect, and is all the more so for pulverizing or spiral fracture.For postoperative Yin Dynasty bone Periprosthetic fracture, there is the scholar to adopt traction therapeutic, healing rate is 66%～100%, but needs long-term bed, and the case generation malunion up to 20% is arranged, thereby most scholar advocates operative treatment.Because the pulp cavity in Fracture of femur district is occupied by the prosthese handle, be used for conventional inner fixer such as intramedullary pin, the blade plate screw etc. of Fracture of femur, all be difficult to use because of passing the pulp cavity that is occupied by the prosthese handle.And can only use steel wire or band ring to prick, screw is tiltedly worn, the blade plate nearside fixedly the reliable internal fixation method of owing such as is screwed in the distally with band, postoperative is because of fixing the unreliable long-term bed that still needs, and very high fracture redisplacement rate is arranged.Be difficult to obtain satisfied curative effect, all the more so for pulverizing or spiral fracture.
Summary of the invention
The technical problem that the present invention will solve provides a kind of artificial femur handle that is used for the operation of hip prosthesis surrounding fracture, and this artificial femur handle can be used for the second operation of hip replacement Periprosthetic fracture, and not only good fixing effect, and structure is single.
