Description

Structure and method for increasing prosthesis stability after artificial hip replacement
Technical Field
The invention relates to a structure and a method for increasing prosthesis stability after artificial hip joint replacement, and belongs to the technical field of artificial joint replacement.
Background
The most common femoral head disease is femoral head necrosis, and for patients suffering from impending collapse or collapsed deformation and long-term pain dysfunction, the operation technology is mature, the success rate is high, the operation has the advantages of good joint movement and early getting out of bed, but several common complications exist, wherein dislocation, relaxation or instability are the most common complications, and how to avoid dislocation, relaxation or instability is a difficult problem which is urgently needed to be overcome by medical staff in the field.
Disclosure of Invention
The invention provides a structure and a method for increasing prosthesis stability after artificial hip joint replacement, which aim to solve the problem that dislocation, looseness or instability often occurs after artificial femoral head replacement.
In order to solve the problems, the structure for increasing the stability of the prosthesis after the artificial hip joint replacement is adopted, which comprises a connecting ligament, wherein nail holes for penetrating bone nails are formed at two ends of the connecting ligament;
in the prosthesis limiting structure, bone nails are respectively penetrated in nail holes at two ends of the connecting ligament, and two ends of the connecting ligament are respectively fixed on the femur and the acetabulum through the bone nails penetrated in the nail holes;
in the prosthesis limiting structure, the connecting ligament is arranged around the prosthesis;
in the prosthesis limiting structure, the connecting ligament is distributed along the circumferential direction of the implanted prosthesis for hip joint replacement;
in the above prosthesis limit structure, the connective ligament is an artificial ligament, an autologous tendon tissue or an allogeneic tendon tissue;
in the prosthesis limit structure, the connecting ligament is a thermoplastic elastomer which meets the standard of a human body implant;
the prosthesis limiting method for hip joint replacement comprises the following specific steps:
after the hip joint replacement is completed, the connecting ligaments are taken out, nail holes are formed in the two ends of the connecting ligaments, the connecting ligaments are straightened, the two ends of the connecting ligaments are fixed on the thighbone and the acetabulum through bone nails penetrating through the nail holes respectively, a plurality of connecting ligaments are distributed and fixed along the circumferential direction of the implanted prosthesis of the hip joint replacement according to the method, and the using number of the connecting ligaments is determined according to the actual condition of a patient.
In the process of the installation and operation of the artificial joint, because of factors such as pathological changes or technology, ligaments and joint capsules which are one of the stable structures of the hip joint of the human body can not be completely repaired after the operation, thereby influencing the stability after the operation of the hip joint of the human body or causing dislocation, and the ligaments and the joint capsules are important components of the hip joint of the human body, and the main functions of the ligaments and the joint capsules are to maintain the stability of the hip joint of the human body and prevent the dislocation. The structure can realize the functions similar to the joint capsule and the ligament, namely, the artificial joint capsule replaces the original joint capsule which cannot be repaired of the human body to avoid dislocation, looseness or instability of the prosthesis, other reinforcing structures are not required to be implanted, the fixing mode is very similar to the original connecting/fixing mode of the human body, the optimized fixation of the prosthesis can be realized, and the application practical application value is very high.
