The invention discloses an internally implanted anatomical elbow joint stabilizer. The internally implanted anatomical elbow joint stabilizer comprises a transverse rod placed in the rotating axis ofa capitulum humerus to serve as a humerus rotating shaft, a fixing plate fixed to ulna olecranon through screws, and a connecting rod connecting the transverse rod with the fixing plate, spacing is formed between the connecting rod and an ulna, between the connecting rod and a radius as well as between the connecting rod and a humerus, the spacing enables the connecting rod not to interfere with the ulna, the radius and the humerus during bending and stretching movement, and the transverse rod, the connecting rod, the fixing plate and the screws are all made of degradable implanting materials.According to the internally implanted anatomical elbow joint stabilizer, after an operation, bending and stretching movement can be achieved, the stability of an elbow joint can be maintained under bending and stretching movement, the appearance of the elbow and clothes wearing are not affected after the operation, stent-tract infection is avoided, the risks of wound infection and skin necrosis are reduced, and a secondary operation for taking out the stabilizer is not needed.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to an implanted anatomical elbow stabilizer. Background technique [0002] Elbow instability caused by injury or release surgery is difficult to manage in orthopedic practice. If the elbow joint is unstable and is not fixed, it will affect the upper limb function of the patient; if it is not handled properly, it will easily lead to secondary or multiple operations, adding additional pain to the patient. The following situations are examples of complex elbow instability: 1. Elbow triad injury and unstable coronoid fracture; 2. Elbow dislocation with severe soft tissue injury; After thorough release of soft tissue and / or excision of heterotopic ossification. The above-mentioned complex elbow joint injuries may still be unstable after bony structure fixation and ligament repair, and the existing traditional treatment methods for elbow joint instability include: 1. Directly nail the elb...
