Rotator band tendonitis

Introduction to Rotating Band Tendonitis The rotating belt includes the supraspinatus muscle, the infraspinatus muscle, the subscapularis muscle, and the small round muscle, which can increase the stability of the humeral head in the glenoid. These tendon tears and inflammation often occur in repetitive movements that require extreme abduction of the shoulder joint (such as baseball, freestyle, backstroke and butterfly strokes, weightlifting, racket movement). When the upper limbs are extended, the humeral head strikes the shoulder and forward. The shoulder ligament causes damage to the supraspinatus tendon, and chronic irritation can cause acromion scapulositis, aseptic inflammation and tendon erosion. Acute and intense violence can cause the rotation band to break. If you continue to train without ignoring the pain, it will lead to periostitis of the supraspinatus tendon and even ablation of the tendon. basic knowledge The proportion of illness: 0.002% Susceptible people: no specific population Mode of infection: non-infectious Complications: spinal muscular atrophy, comminuted fracture

Rotating tendonitis

Cause:

This disease often occurs in repetitive movements that require extreme abduction of the shoulder joints (such as baseball, freestyle, backstroke and butterfly strokes, weightlifting, racket movement). When the upper limbs are extended, the humeral head strikes the shoulder and shoulder ligaments forward. Injury of the supraspinatus tendon, chronic stimulation can cause acromion scapulositis, aseptic inflammation and tendon erosion. Acute and intense violence can cause the rotation band to break. If you continue to train without ignoring the pain, it will lead to the supraspinatus tendon stop periostitis or even The tendon is ablated.

Rotational tendonitis prevention

The main preventive and health measures for this disease are as follows:

1, vitamin supplements are beneficial to the healing of tendonitis, daily vitamin C 1000 mg, -carotene (vitamin A) 10000 international units, especially do not cause joint sprains, such as no ice bag at hand, can be replaced with frozen vegetable bags, the most Use a sports boron band to wrap it around the injured area, but don't be too tight to avoid pain.

2, should fully prepare for activities before the exercise, especially athletes.

3, if tendonitis is caused by work, but must continue to work in the injured area can not get rest, should change the type of work to the higher level, can also let a human engineering expert on-site observation, after the analysis of the work situation And propose changes: before and after work, try to stretch the lower body, take 5-10 minutes every hour to rest the injured area, do not involve the injured part when working, for the sports athletes due to the greater intensity, should be fully treated and rest, Stop the recurrence.

Rotational tendon complication Complications, spinal muscular atrophy, comminuted fracture

In patients with this disease, if you do not pay attention to rest or treatment, because the movement of the lesion is too much, often the condition is constantly worsening. In the later stage, the main complications include the following problems:

1, chronic swelling (gravity edema).

2, muscle atrophy.

3, avulsion fracture.

4, the joint is stiff.

5. The ligament is slack.

Rotating belt tendon symptoms Common symptoms Joint pain, severe pain, arm stretching, pain, upper extremity, abduction, lifting, shoulder movement limitation, thumb, tendon extension... scapular muscle atrophy

For the early stages of the disease, the pain only occurs when the upper arm is lifted high and the abduction is performed. Later, the arm will also appear when the arm is shaken. Usually, the pain occurs when pushing the object forward, but when the thing is pulled, there is no or only There is mild pain.

When the upper arm straightens the shoulder joint and abducts, the rotation is tender, especially when the affected limb is higher than the plane of the shoulder joint (if the affected limb is lower than the body side, there is no tenderness). Acute pain. The decline in shoulder abductor muscle strength is usually due to the disuse of the deltoid muscle. MRI examination does not suggest partial tearing of the rotating band, but can show complete tear.

Rotational tendonitis examination

In order to rule out the condition of bone injury, X-ray examination and bone scan examination should be performed when it is difficult to diagnose.

Magnetic resonance can help determine the severity of tendon injury. Although MRI does not suggest partial tearing of the rotating band, it can show complete tearing, which has a certain significance for differential diagnosis.

Diagnosis and differentiation of rotator cuff tendonitis

diagnosis

Diagnosis can be made based on medical history, clinical manifestations, and examination.

Differential diagnosis

There are two main diseases that need to be differentiated from this disease:

1. Acromial sac bursitis: mainly manifested as pain under the shoulder, tenderness, and can be radiated to the deltoid muscle, severe cases of micro-swollen, long-term disease can cause local muscle atrophy, shoulder joints can not be abduction, external rotation and other actions.

2. Fat biceps long-head tenosynovitis; slow onset, gradually worsening, pain, tenderness, mainly due to intergranular nodules, and biceps muscle resistance to flexion and elbow pain. For a long time, there are also dysfunction and muscle atrophy.
