Which dog's elbow joint is better?
Dog elbow joint development is a hereditary disease of high -incidence of medium and large dogs. Some people think that among large dogs, elbow joint development is more common than hip development. Poor elbow joint development is a collective name of a group of diseases. This group of diseases include unconidity or elbow breaks, crown breaks, chondritis inflammation in the humerus, imbalance of elbow joints, and hyperplasia and inflammation.
The main clinical symptoms are primary limbs. The degree of lameness is divided into level 6: Level 0 is no obvious symptoms. Level 1 occasionally lameness does not appear every step or lameness appears after standing up. Level 2 is a minor lameness every time I go. Level 3 is moderate clamor. Level 4 is severe clamor. Level 5 is severe clamor, and sometimes the affected limbs cannot be loaded. Level 6 cannot bear weight at any time.
We believe that one of the most important elbow joint development is the imbalance of radial ulnar development (usually short ulnar) causing elbow imbalances.

The picture above is the right hand of an animal. From the back, the left side is the inner side of the animal, and the right side of the animal. We can see this animal sitting like a lady (a dog on the right side of the first picture), which receives his hand from his body. We can see that the elbow joint of this animal is relatively severe inner force, and the outside is a forceful power. So this joint force is concentrated in the inside (the left side of the figure). In the end, this hand will be suffered from suffering from the inner wear, which will cause pain and lameness, and then proliferate, and severely causes the separation and break of the bones.
Due to the problem of elbow stress caused a series of symptoms and diseases, the case of elbow joint force is also required in the diagnosis. Generally, the method of shooting X -rays is to let the dog's hands shoot X -rays from a certain angle to observe the lesions of the dog elbow joint. But this method cannot reflect the force of the dog elbow joint. According to the latest research results, we have developed and customized a set of special guarantee tools for mortar and radius to shoot X -rays on the same line of horizontal levels and let forelimbs shoot X -rays. The X -ray films taken by Baoding tools or special Baoding methods can better reflect the force of the elbow joint, and provide a better basis for pet doctors clinically. We can also measure the force angle of the stress (normal dogs at about 81.5 degrees) according to the stress situation of the inside and outside of the elbow mix and the radial osteochroma. By analyzing the situation, the treatment plan is formulated.
However, because pet medical care is a niche industry, these Baoding tools have special requirements in use, and they are very expensive in overseas and difficult to mass production in China. Therefore, there is no way to meet the needs of the domestic pet industry.

In terms of treatment, veterinarians have also been studied clinically, and many orthopedic veterinarians have made great articles here. In order to make the joints uniformly on a straight line, some veterinaries have not expected to cut the humerus and re -connected them, and they have also achieved a certain effect.

But this humerus is a very large bone, and sometimes the stress will reach more than 70%of the body weight, and it is undoubtedly a very adventurous behavior after interruption. Nevertheless, when I went to the Italian meeting last year, there were also orthopedic pet doctors doing the above operations.

Because the above methods have a certain effect, in order to avoid the risk of secondary fractures or implant failures caused by the above methods, smart veterinarians have developed another relatively safe and can make two elbow joints suffer. Uniformly. It is to perform external rotation after interrupting the humerus to make it uniform. This is a good way, but it will make the animal's movement more abnormal (as shown above). No matter which one of the above two methods, it needs to break the humerus's large bone, so the above methods have its natural risks inevitable. So some veterinarians have developed other methods.
Dog elbow joint development
Because the radial ulnar development is not balanced and the ulnar growth plate is prematurely closed, the ulnar is short, so some smart veterinarians choose to interrupt the ulnar in the growth period of animal growth and make it longer. Some veterinarians choose to interrupt the radius to change the radial direction, so that the elbow joint is uniform.
And some of the latest studies in Europe and North America believe that changing the direction of ulnarity can get better results. So Paul technology (Proximal Abduction Ulnar Osteotomy). Judging from the current research, Paul has achieved good results. Dogs that almost all use Paul surgery will be improved to varying degrees. Therefore, like many European orthopedic pet experts, I received Paul surgery certification and became supporters of Paul.
Of course, using all the above surgery solutions only corrects the direction of joint force, making the elbow joint more balanced when walking. But for arthritis or cartilage diseases that have occurred, even if surgery is performed, it will not change it. However, after surgery, the number and dose of dogs using painkillers are greatly reduced, and walking off -the -world decreases to achieve better quality of life.
Therefore, when you look back, if you look at the situation of the elbow joint, the dog elbow joints drawn on the left will be healthier. If the sitting position is like a dog like a lady, it is not suitable for strenuous exercise.
