Symptoms of disease - pain in the delta

Delta (deltoid muscle) is a big fat muscle, starting from the collarbone and shoulder blades on the back of the shoulder and running to the place of his attachment to the upper part of the forearm. This muscle is triceps, i.e. consists of three beams: front, middle and back and their circuits resembles the Greek letter delta, hence, actually, the name. The main function of a delta of the muscles is the ascent and the rotation of the hand. Front head (bundle) deltoid muscles raises his hand forward, average - to the side, the back - to - back. Skeletal structure of the shoulder belt largely determines the width of the shoulders. The so-called "direct" collarbone gives a wide shoulders "square" look at the time as the "oblique" collarbone makes the shoulders of the more visually sloping and narrow. This is something that is given to you by nature. Is it possible to deceive the nature and make your shoulders are broader? Yes, of course. And an important role in this process is given the training of a delta of the muscles.

Proximally fiber front, middle and rear sections of the muscles are attached respectively to the collarbone, acromion blades and spine of the scapula. Distally all of them are attached to the deltoid tuberosity shoulder bone. Different location muscle fibers in the middle part of the muscles in comparison with the front and rear parts of the causes different arrangement of zones of the end records. Function: the front part of the top aspect of the deltoid muscle, covering a head of the humerus bone, bend the upper extremity, the middle part of the alter and the rear part of the unbend the arm at the shoulder joint. All parts of the deltoid muscles help lead the upper extremity. The front portion of the muscle is the antagonist of the rear during flexion and extension of the hand. Reducing at the same time, average, front and rear deltoid muscles help supraspinatus muscle aside the upper extremity in the shoulder joint. Functional unit: the front part of the deltoid muscle function synergistically with clavicular part of the large pectoral muscle, a long head biceps muscles and rostral muscle. The rear part is working together with the widest muscle of back, the big round muscle and long head of the biceps.

Movement, in which participates delta (deltoid muscle):
- Bending arm is made of muscles that cross the transverse axis of the shoulder joint and located in front of it. It is include: the front part of the deltoid muscle; the large breast muscle; rostral -shoulder muscle; biceps muscle of his shoulder.
- Extension of the shoulder muscles produce, also crossing the transverse axis of the joint, but lying back from her, the rear part of the deltoid muscle; the broadest back muscle; big and small round muscles, the long head triceps muscles. Muscles that produce the abduction of the shoulder, cross sagittal axis and are outwards from it, this into the deltoid and supraspinatus muscles.
- Pronation of the shoulder are muscles that cross the vertical axis: subscapular muscle; widest muscle of the back; a large circular muscle; pectoral muscle: the front part of the deltoid muscle.



Which diseases there is pain in the delta

Causes of pain in the delta (deltoid muscle):

1. Damage axillary nerve (n. Axillaris, mixed nerve). The motor fibers innervate the deltoid muscle and small circular muscle, sensitive in composition of the upper lateral cutaneous nerve shoulder (n. cutaneus brachii lateralis superior) - the skin of the outer surface of the shoulder.
The defeat of axillary nerve in the supraclavicular fossa, involving in process of the musculo-cutaneous nerve (n. musculocutaneus), causing paralysis of Erbs: the inability to raise his shoulder as a result of the paralysis of n. deltoideus and violation of the sensitivity of the skin to the outer surface of the shoulder.

2. Reflected the pain of the active myofascial trigger points of the deltoid muscle (m.deltoideus) unlike most of the muscle does not apply to a considerable distance, and is localized in the affected (front, middle or back) part of the muscles. The location of myophascial the trigger point corresponds to the status of a separate zone of the end of the motive of the record.

Activation and long-term existence of myofascial trigger points may be a result of the impact of the trauma that occurs most often during a sporting event or other physical activity, for example as a result of excessive extension of the hands in the shoulder joint, after subcutaneous injection of drugs due to irritation of chemicals tissues in the location of the latent myofascial trigger points. Under the influence of key myofascial trigger points, located in other muscles, especially in infraspinatus muscle, in the deltoid muscle of may appear satellite trigger points.

3. If the hand does not hurt, but a pain, as with bruises, most likely you have spasm (delta) into the deltoid muscle. Spasm can cause: the sharp contraction of the muscle in powerlifting, overloading by the repeated lifting and lowering arm (when walking, skiing, painting walls); the rise and retention of heavy burdens on the shoulders; intramuscular injection in this area, arthrosis, osteochondrosis.

4. Tendinitis of the shoulder and biceps. Although it usually take for the injured shoulder hurts (because it is), bicep tendonitis is actually the result of the exit of its tendon from his bed on the top of the hamerusa, the largest bone of the shoulder. In 95% of cases the situation can be corrected. The pain is felt under the front beam deltoid muscles and therefore is often taken for the injured shoulder. This is usually misdiagnosed as bursitis or stretching of the joint bags shoulder. If biceps tendon not to return to the place, then this will cause the disease shoulder, so as biceps bunch of stabilizes the shoulder joint. When she is not there, where necessary, side and rear shoulder tendons have the additional stress, gradually become inflamed and start getting sick. Ultimately, this can lead to a swelling of the total shoulder joint.

What causes such a widespread and painful injury? For bodybuilders is almost always work on his chest. The main culprits - bench press and leg press the incline bench. Pullovers and breeding of hands is also involved, especially performed on the Pitch-Dec-simulator, when the arms are raised. If you have already had a similar injury, you should keep clear of Pitch-Dec, like the plague.

Does this mean that it is necessary to avoid the load on his chest? Of course, no. Because the exercise is not to blame for what its doing the wrong. First of all, you have to stretch and to establish a tendon. Second: do not use too wide grip with presses. The best on the shoulder width or slightly wider. And, thirdly, to give elbows back so that they, hands and point of contact of the neck to the chest lay on one line, right under the burden. When you touch the chest below this point, or bring your elbows close to the body, the emphasis of the load is transferred from the chest on the tendon front of the deltas and the underlying bunch of biceps in her bed.

If it is not in its place, any additional work cause its friction with the bone in an attempt to regain normal position. This leads to an inflammatory process and the appearance of the tumor. Swollen connection is not placed in their bed. So any exercise and movement irritate her even more, and you have a "self-renewing " injury. If you still continue to train, you have not only local pain - soon will be impossible motion of the whole upper body. You destabilizes the joint bag shoulder. I saw an x-ray of a patient with chronic tendinitis, whose bunch so long was not in a place that gradually rubbed a new couch, in the bones of the parallel nature.

What to do if such an injury? First of all, we must completely eliminate the burden on the chest, as well as other movements that cause pain. Then you need to remove the tumor, so that you can return a bunch of the place. Take anti-inflammatory drugs, such as ibuprofen, and apply ice to the shoulder 2-3 times a day for about 20 minutes. When the swelling went down (usually this happens after 8-10 days) you need to put the bundle on the place. Unfortunately, this is easier said than done. Very few doctors are familiar with this issue and can cope with such a task. If someone is trying to help you by rotating your hands back and forth - in fact, he simply does not understand what it is doing. It is necessary to manipulate the top of the head humerus under the tendon.

5. Pain in the delta may also cause a variety of injury when performing heavy physical loads, or when not correct tactics of the exercise.
