Rotator Cuff Gap Split

Brief introduction of rotator cuff gap On the lateral side of the condyle, the intermuscular space between the subscapularis muscle and the supraspinatus is called the rotatorinterval (Fig. 1). Post described the anatomy in 1978. There is loose connective tissue in the gap, which connects the supraspinatus muscle and the subscapularis muscle, and there is a patellar ligament in front of the gap to strengthen it. DePalma (1973) found that 9% of the rotator cuff gap was open in the normal population. Rowe (1981) reported that in 37 patients with recurrent shoulder subluxation, 20 cases of rotator cuff space were open-ended, which is considered to have a significant correlation. The rotator cuff space division is more common in young adults, and the onset age is 20-40 years old. More. The rotator cuff space division (tearoftherotatorinterval) is the longitudinal tear of the rotator cuff tissue in the direction of the tendon tendon fibers. Compared with the general rotator cuff injury, the etiology, pathology and prognosis have different characteristics. The rotator cuff space is weak in the rotator cuff structure. In the site, once the division occurs, the synergistic effect of the supraspinatus and the subscapularis muscles during the lifting of the upper arm is weakened, and the fixation force of the humeral head on the scapula is lowered, which tends to cause relaxation and slippage of the ankle joint. Ankle instability can cause inflammation and adhesion of the scapular sac, and further secondary joint contracture. basic knowledge The proportion of illness: 0.002% Susceptible people: 20 to 40 years old Mode of infection: non-infectious Complications: Rapping the shoulders

Anterior scaphoid schizophrenia

(1) Causes of the disease

Often caused by work-related injuries, sports injuries, or cumulative damage that is repeated multiple times.

(two) pathogenesis

The injury mechanism caused by the throwing movement causing the split of the rotator cuff is: from the external rotation of the upper arm, the abduction state rapidly changes to adduction, the internal rotation state, leading to the loosening of the connective tissue in the muscle gap, the supraspinatus tendon and the subscapularis split, The anterior wall of the joint capsule can be withdrawn from the gap or simultaneously torn.

Shoulder cuff gap prevention

Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Anterior rotator cuff complication Complications

Can be combined with shoulder joints.

Shoulder sleeve gap splitting symptoms common symptoms fatigue fatigue

1. The pain is located in front of the shoulder, which is a persistent dull pain. The symptoms are aggravated after the shoulder joint movement, and there is localized tenderness in the lateral scapular space of the condyle.

2. Weakness and fatigue.

3. Unstable or loose shoulders.

4. The joints are ringing.

Examination of rotator cuff clearance

X-ray film

Keeping the arm in the maximum upper position, sometimes stumbling can occur.

Ankle arthrography

It shows that the contrast agent overflows in the rotator cuff space, and forms a band-like, papillary or small piece of irregular shadow on the outside of the condyle.

3. Arthroscopy

It can be seen that the rotator cuff space is congested and exuded.

Diagnostic diagnosis of scapular sleeve gap

1. History of shoulder trauma.

2. Pain in the shoulder and fatigue in the shoulder, fatigue.

3. The external constriction of the condyle is tender.

4. The ankle joint is unstable.

5. The anterior and posterior X-ray films of the arm lifted the ankle joint slippage, and the articular angiography showed abnormal development of the rotator cuff space.
