Artificial hip joint prosthesis handle for treating periprosthetic fracture

Abstract

The invention discloses an artificial hip joint prosthesis handle for treating a periprosthetic fracture, and belongs to the technical field of orthopaedics medical apparatuses. The artificial hip joint prosthesis handle is used for treating the periprosthetic fracture generated after hip joint replacement. According to the technical scheme, a plurality of fixing holes are formed in the middle section and the distal end of the prosthesis handle and penetrate through the prosthesis handle from the outer side of the prosthesis handle to the inner side of the prosthesis handle, the length center lines of the fixing holes are perpendicular to the length direction of the prosthesis handle, and the multiple fixing holes are parallel. According to the artificial hip joint prosthesis handle, the fixing holes are reserved in the prosthesis handle, when the periprosthetic fracture generated after hip joint replacement is treated, a doctor can only use plate fixation, and cerclage wiring fixation is avoided. Steel plate fixing screws can penetrate through the reserved fixing holes to be fastened to an inner cortex and an outer cortex on the periphery of the femoral fracture, the good fixing effect is achieved, and mechanical stability is greatly improved. The artificial hip joint prosthesis handle is simple in structure and convenient to use; the fracture portion on the periphery of the prosthesis handle is stably and firmly fixed, the ideal operation effect is achieved, and recovery and functional recovery of a patient are quite facilitated.

Description

technical field [0001] The invention relates to an artificial hip joint prosthesis handle for treating periprosthetic fractures after hip joint replacement, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Among middle-aged and elderly orthopedic patients, a large proportion of them suffer from hip joint diseases, mainly femoral head necrosis caused by various reasons and femoral neck fractures caused by falls. With the improvement of people's living standards and the continuous enhancement of health concepts, the number of patients undergoing hip replacement is increasing, which provides the best treatment for the complete cure of diseases and the restoration of hip joint function. However, with the increase in the number of hip replacements, the incidence of postoperative femoral periprosthetic fractures has also increased significantly. The reasons are mostly caused by external forces such as wrestling and falling. Postoperat...

AI Technical Summary

Problems solved by technology

Since most of the patients are elderly and often have osteoporosis, the combination of steel plate and cable cerclage fixation is usually used clinically. If the single cortical screw is inserted, the stability of the plate fixation will be affected, and the use of steel cable cerclage will inevitably affect the blood supply of the corresponding part, so the surgical effect is not ideal
