1. Delta muscle fibrosis

Delta fibromyalgia is a disease that affects the mobility of the shoulder joint. Its characteristic makes it impossible for the patient to bring the arm into contact with the chest at the anatomical position of the shoulder blade. The disease can be congenital or acquired. Cases of Delta muscle fibrosis may be due to the patient's history of multiple intramuscular injections into the Delta muscle.
Delta muscle fibrosis has a gradual progression, muscle cells gradually turn into fibroblasts due to physico-chemical factors such as trauma (muscle constriction), local bleeding, edema (not nourishing the tissues). muscle organization) or by chemical agents that change the nutrients as well as the metabolism of muscle cells. The result of this condition will be loss of elasticity of the muscle, causing contraction and loss of motor function of the muscle.
Delta muscle fibrosis can easily be misdiagnosed as anterior shoulder dislocation, anterior neck paralysis. Therefore, an accurate diagnosis of fibromyalgia will help to correct it more effectively, especially in the early stages.

2. Diagnosis of disease

2.1. Implementing the quadrants

Examination of medical history: Injury, infection of shoulder joint, antibiotic or vaccine injection, time of appearance of deformity.
Evaluation of clinical function: To perform this process, the doctor will rely on the most prominent and recognizable signs of Delta muscle fibrosis through assessment of joint movement, palpation of the shoulder joint...
Observe the shoulder joint: First, we will observe from the front the sacral processes (shoulders are lowered, the upper ends of the bones are protruding first). Next, we will observe the forearms and elbows indents on the skin surface, grooves. concave along the muscle body (medial bundle of the Delta muscle)
Observation from the back: lateral scapula are pulled low with fibrosis, the medial margin of the scapula is detached from the posterior thoracic wall, the lower pole of the scapula can be rotated outward. In addition, the spines behind the shoulder blades are prominent.
The patient cannot bring the arm close to the torso when at rest, the elbows are difficult or impossible to touch when bringing the arm forward in the flexed elbow position. The shoulder blades are raised and rotated in the shape of a bird's wings.
Mobilize the shoulder joint. The brachial-brachial angle is the critical angle to evaluate the fibromyalgia of the Delta. If this angle is greater than 25 degrees, it will be one of the decisive indicators of surgical treatment.
Move shoulder-width apart. The degree of delta muscle fibrosis can limit adduct motion in the scapula below 90 degrees and even below 45 degrees.
Shoulder joint movement. The disease can limit shoulder joint movement to less than 90 degrees, even the spine may tilt to the same side.
Based on the preliminary examination results, the doctor can give some indications for tests such as: Ultrasound (Can see the fibrous strip of the Delta muscle, the size is less than 1cm in diameter and about 6-8cm in length. ); X-ray . Observe the image of shoulder dislocation; Electromyography )This test will determine if there is damage to the peripheral nerves that control muscle movement); Muscle enzymes (measurement of Creatinine Phosphokinase to determine if there is a state of destruction of muscle cells); histopathology (assessment of muscle degeneration or invasion of fibroblasts replacing muscle cells)

2.2. Differential diagnosis

Some diseases related to neuromuscular and shoulder joint need to be differential diagnosis such as: Duchenne muscular dystrophy, spinal muscular dystrophy, congenital polyarthritis, brachial plexus palsy.

3. Principles of rehabilitation of fibromyalgia Delta

Delta fibromyalgia rehabilitation treatment is based on increased mobility of the shoulder and elbow joints. At the same time, against fibrosis and muscle atrophy in the shoulder joint.
Some commonly used methods and techniques for the recovery of fibromyalgia Delta:
Infrared physiotherapy: high frequency electricity and ultrasound. This method is applied 72 hours after Delta muscle surgery and this is the preparation phase before entering the training process. Mobility exercises: Doctors will base on the specific situation of each patient to prescribe exercise exercises to restore function of fibromyalgia. The patient will be instructed by the technicians to perform exercises such as: shoulder-hand joint exercise, humeral head rotation, external arm rotation, exercise combined with external flexion and external rotation, shoulder cross training, exercise training. external rotation of the arm, combined movement of flexion and external rotation, movement of the arm in a sitting position. After rehabilitation of Delta fibromyalgia, patients are still monitored and re-examined after 3 months, 6 months, 12 months and 36 months to ensure that there will be no recurrence of fibromyalgia conditions, limiting movement or joint deformity.
