Can you dislocate your manubrium?
Manubriosternal dislocations are divided into two types: In a Type I dislocation, the body of the sternum is displaced in a dorsal direction; in Type II dislocation, the body is displaced to the ventral side of the manubrium. A manubriosternal dislocation may be caused by direct or indirect trauma.
What type of joint is Manubriosternal joint?
secondary cartilaginous joint
The manubriosternal joint is a type of secondary cartilaginous joint or symphysis, formed by the inferior border of the manubrium and the superior border of the sternal body. Both sides of the joint are irregular and undulating and covered with hyaline cartilage 2.
Does the Manubriosternal joint move?
There is very little movement of the manubriosternal joint but there may be a small amount of angular movement during respiration 4.
Can a sternum be dislocated?
If you dislocate your sternum, it usually become separated from the clavicle. However, ribs can separate from the sternum as well. In many cases, as the joint that connects the two bones separates, you’ll hear a popping sound.
What to do for a type 2 manubriosternal dislocation?
In our table, most patients had type 2 dislocation of manubriosternal joint and thoracic fracture. Some studies recommended conservation treatment for sternal fracture and MSJ dislocation [ 7, 8, 13 ]; while others prefered to open reduction and fixation [ 5, 9, 10, 11, 12 ].
What kind of dislocation is manubriosternal joint fracture?
The powerful force is transmitted from the clavicles and ribs to the sternum, resulting in the fracture and dislocation of the sternum. For manubriosternal joint dislocation, it was a type 2 with a flexion-distraction injury of the thoracolumbar spine.
Which is the best treatment for MSJ dislocation?
Some studies recommended conservation treatment for sternal fracture and MSJ dislocation [ 7, 8, 13 ]; while others prefered to open reduction and fixation [ 5, 9, 10, 11, 12 ]. In Jones’s study [ 9 ], they had patients combined with MSJ dislocation and lower cervical and lumbar fractures.
How is manubriosternal dislocation related to the thoracic cage?
The patient had appearance deformity of the manubriosternal joint. This case supports the concept of the existence and clinical relevance of the thoracic cage theory, the thoracolumbar vertebrae should also be included in the thoracic cage theory. Manubriosternal dislocations are rare, and may be related to spine fractures.
