A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. [1] A partial dislocation is referred to as a subluxation . Dislocations are often caused by sudden trauma on the joint like an impact or fall.
The shape of the ends of the bones—Some joints normally have a large range of movement, such as the shoulder and hip. Both are ball-and-socket joints. If a shallow rather than a deep socket is inherited, a relatively large range of movement will be possible. If the socket is particularly shallow, then the joint may dislocate easily.
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
Hip Dislocation. A hip dislocation occurs when the ball of the hip joint moves out of place from where it’s supposed to be in the socket. The most common cause is car accidents. Jumping down ...
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
Acromioclavicular joint dislocation is a common injury to the shoulder and is occurs most often in athletes. [5] This injury has a higher prevalence in men compared to women and approximately 5 men for every 1 women experience this type of injury. [ 5 ]
Subluxation is when the joint is still partially attached to the bone. [2] When a person has a dislocated jaw it is difficult to open and close the mouth. [3] Dislocation can occur following a series of events if the jaw locks while open or unable to close. If the jaw is dislocated, it may cause an extreme headache or inability to concentrate.
A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa. [2] Symptoms include shoulder pain and instability. [ 2 ] Complications may include a Bankart lesion , Hill-Sachs lesion , rotator cuff tear , or injury to the axillary nerve .
