Shoulder
The shoulder is a body part in which the arm is attached to the trunk. It consists of the union of three bones: humerus, scapula and collarbone and perform a variety of movement thanks to a complex system composed of four articular joints that act synergistically.
- Glenohumeral joint
It is the main joint, anteriorly in the tendon of the long head of the biceps and the subscapularis muscle is. On its rear face is a rotator cuff formed by the supraspinatus, infraspinatus and teres minor that are inserted into the greater tuberosity - Ariculación acromioclavicular
It is a very mobile joint held by the acromioclavicular ligament. Connects the lateral end of the clavicle to the acromion. - Joint esternoclavicular
Shaped saddle and is held by the ligament costoclavicular. It is a synovial joint (moves freely) and connect the clavicle to the sternum. - Scapular thoracic joint and scapular humeral
Joints are atypical, scapular humeral includes the subacromial space.
Major shoulder pathologies
- Rheumatoid arthritis
- Osteoarthritis
- Strain and biceps tendinitis
- Problems of sternoclavicular joint
- Thoracic Outlet Syndrome
- It is produced by compression of the neurovascular structures leaving the thoracic cavity, when addressing the upper extremities. The most common symptom is pain due to compression of the brachial plexus
- Labrum Breaks
- Rotator cuff tear
- Capsulitis
- Calcifying tendinitis
- Dislocation and recurrent dislocation
In recent years there has been a dramatic improvement in imaging techniques, in minimally invasive surgical procedures and joint replacement that affect the shoulder.
FAQ
- I have been told that I have a torn rotator cuff (supraspinatus tendon) Is it better to have surgery?
Depends on the type and size of the tear, of age and physical activity undertaken. Typically a complete break of more than 1 cm. be operated. The procedure is performed arthroscopically (minimally invasive, minimum income, only herida) and results are usually excellent in experienced hands. Including elderly patients in pain can perform arthroscopic debridement infiltration associated with hyaluronic acid and growth factors which can greatly alleviate the symptomatology. - Note that the shoulder seems to be out of place and it hurts in the front and top. An MRI can not see anything, What can I do?
If you made often requiring external rotation movements and retropulsion (namely, bring the shoulder back and throw up as if something) you may have a SLAP lesion (impeller and detachment of the biceps tendon). The best treatment is the arthroscopic repair in the hands of a skilled surgeon. - Are growth factors are useful when a cuff is repaired?
The growth factor in the arthroscopy is useful to promote healing of the rupture, however, not all types of growth factors that are currently on the market served (some may worsen fibrosis and stiffness), so you should always check with an expert. - I have a torn sleeve and I want to infiltrate hyaluronic acid, Will I will make some effect?
In a ruptured tendon, hyaluronic acid does not make any effect, however, when there is a joint problem, as the incipient osteoarthritis between the humeral head and the glenoid, it can be very effective - I lost shoulder movement largely after surgery, ¿Should I conform?
You must go to an experienced surgeon, is possible to recover much of the movement making a arthrolysis of adhesions and fibrosis by arthroscopy.
