Where does the word syn come from in synostosis?
Craniosynostosis (from cranio, cranium; + syn, together; + ostosis relating to bone) is a condition in which one or more of the fibrous sutures in an infant skull prematurely fuses by turning into bone (ossification).
When do you need surgery for a synostosis?
A synostosis is a fusion of two neighboring bones. Sometimes, more than two bones can be involved, creating an aggregate synostosis where multiple bones are joined together when they should be separately articulated. In some cases, treatment may not be necessary, and in others, surgery is required to separate the bones and correct the problem.
Do you need to separate Y shaped synostosis?
Y-shaped synostosis should be separated whether the branches are symmetrical or asymmetrical, the latter having one branch shorter than the other. Because the epiphyses are already divergent, simple separation does not effectively correct Y-shaped synostosis.
When do you need a cast for synostosis?
After surgery, the site may need to be placed in a cast for stability during healing. A synostosis is a fusion of two neighboring bones. Sometimes, more than two bones can be involved, creating an aggregate synostosis where multiple bones are joined together when they should be separately articulated.
Where do most cases of synostosis take place?
Most cases are sporadic, congenital (due to a defect in longitudinal segmentation at the 7th week of development) and less often post-traumatic, bilateral in 60%, and more common in males. Familial cases in association with autosomal dominant transmission appear to be concentrated in certain geographic regions, such as Sicily .
Why do people with synostosis have more pain?
Increased wrist motion may compensate for the absent forearm motion. It has been suggested that individuals whose forearms are fixed in greater amounts of pronation (over 60 degrees) face more problems with function than those with around 20 degrees of fixation. Pain is generally not a problem, unless radial head dislocation should occur.
