What is Shoulder Impingement Syndrome?

Acromion impingement occurs when the greater tuberosity of the humerus repeatedly impacts the anterolateral structure of the acromion during abduction of the shoulder joint, causing hyperplasia and sclerosis on the surface of the humeral head of the acromion. The compression of the glenohumeral joint tissue below the acromion leads to shoulder pain, limited range of motion, and local mechanical irritation symptoms known as acromion impingement. Treatments for acromion impingement include:

1. Conservative treatment: Some patients gradually improve and recover function through conservative treatment. This includes rest and avoidance of lifting; physical therapy; local blocking, acupuncture, and massage may also be beneficial. Physical therapy takes several weeks to several months.

2. Surgical treatment: If conservative treatment is ineffective, surgical treatment is required. The goal of surgical treatment is to eliminate the impact of the humerus and create a space for its movement.

3. Minimally invasive surgical treatment can be used to decompress the acromion impingement.

Precautions for patients with acromion impingement:

1. Minimize shoulder activity in daily life and perform certain professional training.

2. After surgery, patients should pay attention to their diet, avoid spicy and stimulating foods, rest more, and avoid strenuous exercise to prevent affecting the surgical treatment outcome. Rehabilitation training can be performed according to the doctor's instructions.
