Patologia do ombro


Patologia do ombro
Fracturas

As fracturas podem envolver a clavícula, colo do úmero e omoplata
A clavícula é o osso do organismo que mais se fractura
Há um ponto fraco a a 1/3 da extremidade externa. Nesta fractura a espádua o osso tende a descer
As fracturas da clavícula e do colo do úmero são provocadas em geral por quedas, colisões ou acidentes de automóvelComo a omoplata está protegida pelo tórax e músculos circundantes, a sua fractura é rara, podendo observar-se em acidentes de automovel, quase sempre associada a lesões do tórax

Instabilidade da espadua


Left: Normal shoulder stability. Right: Head of the humerus dislocated to the front of the shoulder.



Luxações  da espadua

As luxações são  frequentes.
Como os tendões e ligamentos estão essencialmente nas regiões superior e anterior, nas luxações o úmero tem tendência a se deslocar para baixo
Como os principais ligamentos cruzam a face superior da articulação, é mais frequente a luxação inferior do úmero, na direcção da axila
A luxação acromio-clavicular é conhecida como espadua separada
A luxação esternoclavicular separa a clavícula do esterno
Na luxação glenohumeral a separação pode ser para diante ou para trás

Bursites da espadua
A bursite infra-acromial pode tornar-se muito dolorosa quando o deltóide comprime a bolsa durante o movimento do ombro
Shoulder

Shoulder Bursitis


Ombro congelado
A cápsula da articulação gleno-umeral inflama-se e torna-se rígida e forma adesões que limitam grandemente os movimentos da articulação.
Esta situação dura seis meses a mais de três anos
Muitas vezes a causa é desconhecida mas nalguns casos está associada a imobilização por fractura ou a traumatismos

o the ligaments that hold your collarbone to your shoulder blade. In a mild separated shoulder, the ligaments may just be stretched. In severe injuries, ligaments may be completely ruptured.
In most people, a separated shoulder doesn't usually require surgery. Instead, conservative treatment — such as rest, ice and pain relievers — is often enough to relieve the pain. Most

Sindroma de impacto do ombro ( impingement)
Impingement syndrome occurs when the rotator cuff tendons rub against the roof of the shoulder, the acromion.


The acromion "impinges" on the rotator cuff and bursa.
In most parts of the body, the bones are surrounded by muscles. In the shoulder region, however, the muscle and tendons are surrounded by bone. If one taps on the top of the shoulder, bone can be felt immediately under the skin. Underneath that bone is the rotator cuff, a group of muscles and tendons that we use to lift the arm up overhead. The rotator cuff is sandwiched between the arm bone and the top of the shoulder (acromion). This unique arrangement of muscle and tendon between bone contributes to the development of impingement syndrome (shoulder bursitis, rotator cuff tendinitis).
When an injury to the rotator cuff occurs, it responds by swelling much the way an ankle does when it is sprained. However, because the rotator cuff is surrounded by bone, its swelling causes a number of events to occur. The pressure within the tendon increases, resulting in compression (squeezing) and loss of blood flow in the capillaries (small blood vessels).
When the blood flow is reduced, the tendon tissue begins to fray much like a rope. As the tissue swells, it results in the classic features of a pain like a toothache.
