The shoulder joint is the joint with the largest range of motion in the upper limbs.
It is indispensable for most of the upper limb activities in daily life.
Such as lifting heavy objects, dressing, drinking water, writing, daily study and work, etc.
Over time, shoulder injuries are inevitable.
In clinical work.
Rotator cuff injuries are the most common disease in the field of sports medicine.
What does a rotator cuff injury look like? How is it**?
This article has you covered.
After playing ball and getting clean, I suddenly can't lift my hands, can't lift heavy objects, and has symptoms such as shoulder pain and weakness?
Wei Hewei, director of the Department of Sports Medicine of our hospital, reminded that it is likely that a rotator cuff injury occurred.
Where is the rotator cuff?
The rotator cuff muscles are composed of supraspinatus, infraspinatus, teres minor and subscapularis muscles, which have the functions of maintaining the joint cavity sealing, supporting and dynamically stabilizing the glenohumeral joint, preventing the humeral head from moving upward, and ensuring the smooth completion of abduction, internal rotation and external rotation of the shoulder joint.
Rotator cuff injury**.
1.Acromion shape problem: Everyone's acromion shape may be different, there are flat, curved, hooked, etc. When the shoulder joint is moving, the greater tuberosity of the humerus is easy to hit the acromion and the ligaments next to it, resulting in rotator cuff injury.
2.Degeneration of rotator cuff tissue: With age, rotator cuff tissue will degenerate, which is a major reason why rotator cuff injuries are more common in middle and old age.
3.Overuse: Shoulder overuse can lead to rotator cuff injuries in certain occupations that require long-term shoulder movement, such as teachers, athletes, painters, and housewives who often do household chores.
4.Trauma: Acute trauma may lead to rotator cuff injury, such as avulsion fractures of the greater tuberosity of the humerus.
In addition, the impingement theory holds that 95% of tendon rupture is caused by impingement. When the shoulder is abducted, the tendon cuff is bumped by the rocoacular arch, causing congestion, edema, and degeneration, resulting in tendon rupture. According to the theory of degeneration and trauma, rotator cuff tears most often occur approximately 1 cm from the supraspinatus tendon dental point, which is considered to be a risk zone for ischemia.
What are the manifestations of rotator cuff injury?
Rotator cuff injuries are one of the most common sports injuries in the upper extremities. Shoulder pain, weakness, and limitation of movement may manifest as well as unusual murmurs.
Patients with mild rotator cuff injuries have less significant pain, and over time, rotator cuff injuries worsen and pain becomes more severe. Rotator cuff injuries are typically characterized by nocturnal pain, back-hand pain, and an "arc of pain," which worsens when the shoulder is abducted 60° to 120°.
What is the mechanism of rotator cuff injury?
In daily life, the repeated abduction of the shoulder joint is particularly unfriendly to the rotator cuff, such as playing badminton, baseball, swimming, weightlifting, etc., repeated abnormal movements make the rotator cuff tendons and bones and ligaments constantly rub, or the repeated stretching of the muscles causes minor injuries, strains and even tears of the tendons and bursa. Shoulder turns in gymnastics, sudden excessive shoulder extension during weight lifting, throwing shots, and strong smashes in badminton are typical mechanisms that cause this injury.
How about rotator cuff injuries**?
First, the conservative method.
When the rotator cuff injury is short-lived, the severity of the injury is mild, and there is no significant pain and limited mobility, conservative treatment may be an option**.
1.Brake breaks.
In the acute phase, the first thing to do is to rest the affected shoulder, reduce the movement that causes symptoms, and avoid overstimulation of the injured area and induce pain. When symptoms are severe, an upper limb sling can be used for suspension and braking rest for more than 2 weeks until the pain is significantly relieved.
2.Oral anti-inflammatory pain relievers.
Oral non-steroidal anti-inflammatory drugs are often preferred to reduce inflammation, and appropriate oral administration can reduce inflammation and relieve pain, and the effect is better with physical **, and it is necessary to take the drug under the guidance of a professional doctor.
3.Intra-articular drug injections.
4.Physics**.
Cold therapy, laser, medium frequency, hot hermitage**, iontophoresis, traditional Chinese medicine rubbing** (Wentong ointment, painkiller oil) and other physical ** can warm the meridians, promote blood circulation and eliminate blood stasis, and relieve pain.
2. Surgery**.
If the condition does not improve or worsens after conservatism**, surgery should be considered as soon as possible**. At present, arthroscopic minimally invasive surgery is the most commonly used surgical modality.
3. How to train effectively after surgery.
Depending on the severity of the rotator cuff injury, active or passive shoulder training is generally started at 0-6 weeks.
1.Basic version of active training: the affected limb gradually recovers the range of motion of shoulder forward flexion, abduction, external rotation and internal rotation through the three actions of "climbing the wall", "lying on the table" and "rubbing the back", and completes the overhead action, which is required to gradually reach the contralateral level.
2.Enhanced passive training: training through the upper limb CPM machine.
How can rotator cuff injuries be prevented?
1.Pay attention to warm-up when exercising, and the exercise posture is reasonable and standard.
2.Exercise should be moderate, not high-intensity exercise.
3.Avoid overstretching the shoulder joint.
4.Prevent accidents, such as accidental falls.
5.Strengthen shoulder muscle training, such as elastic band resistance training.
