Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a prosthesis for treating glenoid defect caused by shoulder joint dislocation.
Background
The current arthroscopic operative treatment method for recurrent shoulder dislocation is mainly divided into two steps, namely intra-articular stabilization operation (Bank prosthesis) and extra-articular stabilization operation (Bristow-L atarjet operation), under-arthroscopic Bank prosthesis has become mature and is continuously mastered by surgeons in the past decades, while under-arthroscopic Bristow-L atarjet operation has a steep learning curve and a large difficulty coefficient and is still improved in the last few years, although the operation method gradually achieves the curative effect similar to the incisional operation, is even better than the incisional operation in some aspects, and has the disadvantages that (1) the operative operation difficulty is increased, the operation time can reach more muscle tissues, the swelling can be treated for more time, the degree of the injury is 5-7 hours, the injury is about 40 percent of the dislocation of the whole body joint, the upper limb nerve injury of a patient is increased, the probability of the patient is increased, and the time of the patient is prolonged, the patient has a significant risk of heel trauma caused by the double arm anesthesia, and the patient has a longer arm anesthesia time, and the patient has a significantly longer arm pain.
Disclosure of Invention
The invention aims to provide a prosthesis for treating glenoid defects caused by shoulder joint dislocation, which can reduce the operation difficulty, reduce the operation risk brought by Bristow-L atarjet operation and relieve the pain of a patient.
The technical scheme adopted by the invention is as follows: the utility model provides a treatment shoulder joint dislocation leads to the fact defective false body of glenoid, includes that semicircle platform shape false body holds in the palm and the screw, and the false body holds in the palm and opens on the great semicircular bottom surface of radius and has the draw-in groove, is equipped with the gasket in the draw-in groove, and the gasket uses with the draw-in groove cooperation, and the straight side of false body support is opened has the dead slot, and the arc side of false body support still opens has the screw hole, and the screw hole is used for cooperating the screw.
The invention is also characterized in that:
the number of screw holes is two at least, and each screw hole distributes at the dead slot edge.
The gasket is an arc-shaped gasket, one side of the gasket is an arc-shaped end face, the other side of the gasket is a straight end face, and the straight end face of the gasket is in contact with the bottom face of the clamping groove.
The dead slot is a groove with a semi-arc bottom surface and is used for bone grafting.
The prosthesis support is made of titanium alloy.
The gasket is a polyethylene gasket.
The prosthesis for treating the glenoid defect caused by shoulder joint dislocation has the advantages that when the prosthesis is applied to an operation, the operation time can be saved, the operation difficulty can be reduced, meanwhile, the operation risk caused by the Bristow-L atarjet operation can be reduced, and the pain of a patient can be relieved.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention provides a prosthesis for treating glenoid defect caused by shoulder joint dislocation, which comprises a semicircular truncated cone-shaped prosthesis support 1 and a screw 5, wherein the upper bottom surface and the lower bottom surface of the prosthesis support 1 are two semicircular bottom surfaces with different radiuses, a clamping groove 6 is formed in the semicircular bottom surface with the larger radius of the prosthesis support 1, a gasket 2 is arranged in the clamping groove 6, the gasket 2 is matched with the clamping groove 6 for use, a hollow groove 3 is formed in the straight side surface of the prosthesis support 1, a screw hole 4 is formed in the arc-shaped side surface of the prosthesis support 1, and the screw hole 4 is used for being matched with the screw 5 for use.
The number of screw holes 4 is at least two, and each screw hole 4 distributes at the edge of dead slot 3.
The gasket 2 is an arc-shaped gasket, one side of the gasket 2 is an arc-shaped end face, the other side of the gasket 2 is a straight end face, and the straight end face of the gasket 2 is in contact with the bottom face of the clamping groove 6.
The empty groove 3 is a groove with a semi-arc bottom surface, and the empty groove 3 is used for bone grafting.
The prosthesis support 1 is made of titanium alloy.
The gasket 2 is a polyethylene gasket.
During operation, as shown in fig. 4, firstly, the bone defect in front of the shoulder glenoid is rubbed into a plane by a grinding drill under an arthroscope and is matched with the flat end surface with the empty groove of the prosthesis, then, the autogenous bone or the allogeneic bone is implanted into the empty groove 3 of the prosthesis, the prosthesis is placed into a joint cavity and is attached to the front of the glenoid, and the screw 5 is screwed in, so that the operation is very simple and time-saving.
The prosthesis for treating the glenoid defect caused by shoulder joint dislocation has the advantages that when the prosthesis is applied to an operation, the operation time can be saved, the operation difficulty can be reduced, the operation risk caused by a Bristow-L atarjet operation can be reduced, and the pain of a patient can be relieved.
