How to check rotator cuff injury?

summary

Rotator cuff injury is a disease caused by the injury of the shoulder joint. Many people have heard of rotator cuff injury, but there is no in-depth understanding of this disease. Rotator cuff injury will bring harm to people, so people need to know how to check the diseases around us, how to check rotator cuff injury? Now let me tell you something.

How to check rotator cuff injury?

X-ray plain film examination has no specificity for the diagnosis of this disease. When the distance between the acromion and the top of the humeral head is 1.5m, the distance between the acromion and the top of the humeral head should not be less than 12mm. If it is less than 10mm, it generally indicates that there is a large rotator cuff tear, which can promote the humeral head to move up under the traction of deltoid muscle. X-ray plain film shows that the subacromial space is narrow. In some cases, the cortical bone sclerosis surface of the greater tubercle is irregular or there is bone wart formation, The cancellous bone showed bone atrophy and osteoporosis,

In normal anatomy, the glenohumeral joint communicates with the bursa of the inferior scapular muscle and the tendon sheath of the long head of the biceps brachii, but does not communicate with the bursa of the acromion or deltoid muscle. If the bursa of the acromion or deltoid muscle is developed in glenohumerography, it indicates that the rotator cuff, the isolated structure of the glenohumeral joint, has been ruptured, As a result, the contrast agent in glenohumeral joint cavity overflowed through the rupture and entered into the acromioclavicular bursa or deltoid bursa. Glenohumeral joint cavity radiography is a very reliable diagnostic method for complete rotator cuff rupture, but it can not make a correct diagnosis for partial rotator cuff rupture.

CT examination alone is of little significance in the diagnosis of rotator cuff lesions. The combined use of CT examination and arthrography has a certain significance in finding the rupture of subscapular muscle and infraspinatus muscle and finding the coexisting pathological changes. When the rotator cuff extensive tear is accompanied by glenohumeral joint instability, CT examination is helpful to find the abnormal and unstable anatomical relationship between the rotator cuff and the humeral head.

matters needing attention

There are many inspection methods for rotator cuff injury. The above three inspection methods are relatively common. There are also some common inspection methods such as B-ultrasound and X-ray. We have introduced a lot of them before, so we should be clear about them. Therefore, we will not introduce them to you much. We must solve any problems of rotator cuff injury as soon as possible, So that we can cure the disease earlier.
