Description

A kind of artificial femur handle for fracture surgery around hip joint prosthesis
Technical field
The present invention relates to a kind of inner fixing device of human body, be specifically related to a kind of fixture of human femur under loading fracture.
Background technology
The patient who accepts in recent years hip replacement (THA) and overhaul technology constantly increases, and after THA, Aged Patients extends and activity increase life cycle, and the incidence rate of Periprosthetic Fracture After Total Hip Arthroplasty and complexity are increased thereupon.Periprosthetic Fracture After Total Hip Arthroplasty has become the third-largest reason that Switzerland's patient's full hip-joint is overhauled.There is report to show, the incidence rate of Periprosthetic Fracture After Total Hip Arthroplasty accounts for 1.1% of Primary replacement, after overhaul technology 4%, in Replacement of Hip Joint or the Periprosthetic Fracture After Total Hip Arthroplasty of postoperative generation, due to the existence of prosthesis handle, general blade plate or intramedullary pin are difficult to application, and adopt steel wire or band cerclage or cerclage to add the fixing method of blade plate screw, fracture redisplacement rate is high, is difficult to obtain satisfied curative effect, all the more so for pulverizing or spiral fracture.For postoperative abundant bone Periprosthetic fracture, there is scholar to adopt traction therapeutic, healing rate is 66%～100%, but needs long-term bed, and has the case generation malunion up to 20%, thereby most scholar advocates operative treatment.Because the pulp cavity in Fracture of femur district is occupied by prosthesis handle, for the conventional inner fixer of Fracture of femur as intramedullary pin, blade plate screw etc., all because being difficult to use through the pulp cavity being occupied by prosthesis handle.And can only use that steel wire or band cerclage, screw are tiltedly worn, blade plate nearside is screwed etc. with the fixing distally of band and owes reliable internal fixation method, postoperative because of the fixing unreliable long-term bed that still needs, and has very high fracture redisplacement rate.Be difficult to obtain satisfied curative effect, all the more so for pulverizing or spiral fracture.
Summary of the invention
