My child was born without metopic ridge, yet a definitive ridge has now formed. Her head growth has been normal. She is now 1. Should I be concerned?
See pediatrician: It may not be anything to worry about, but your pediatrician should evaluate not only the child's head growth (head circumference) but also the shape of the head. Just having a ridge in and of itself does not always mean that something is wrong, but when it associated with an abnormality of the shape of the skull, it can be a problem. ...Read more

Could craniosynostosis be missed until 15 months? Child has a ridge along metopic suture, but pediatrician says too late for diagnosis.
Craniosynostosis: Ridging along a metopic suture does not necessarily mean craniosynostosis. There are other findings associated with it that fit into the diagnosis of trigonocephaly. It is not too late for a diagnosis and a work up by a craniofacial surgeon might be helpful here for you. ...Read moreSee 2 more doctor answers
Metopic synostosis: Surgery is really the only option at present. Surgery for metopics is really based on how severe the synostosis is on examination. A mild ridge most do nothing. Severe ridge with dimpling lateral to the eyes and close set ears are the more concerning types. ...Read moreSee 2 more doctor answers
My so was born with Metopic Synotosis (Cranio Synotosis) I was wondering what long term issues will he suffer with he now has high blood pressure?
Unlikely: Metopic synostosis is more a cosmetic issue than anything else. The majority of babies are born with that suture already functionally closed in the womb. Some have a pronounced keel shaped forehead that fades as they get older, but it does not create the same type of problems we find with other forms of synostosis. ...Read more
Rigidity: Rigidity is an abnormality of muscle tone that can occur in certain neurological conditions. It is a resistance to movement. An example of this is Parkinson's disease which can cause rigidity. That is not the only condition that can cause rigidity though. ...Read more
Does this help?: 'cogwheel' rigidity and 'leadpipe' rigidity are two types identified with parkinson's disease. 'leadpipe' rigidity results when an increase in muscle tone causes a sustained resistance to passive movement throughout the whole range of motion, with no fluctuations.'cogwheel' rigidity is a combination of leadpipe rigidity and tremor which presents as a jerky resistance to passive movement. ...Read more
Spasticity is an increased resistance to the passive movement of a joint due to abnormally high muscle tone, and varies with the amplitude and speed of the joint motion. Seen after a stroke.
Rigidity is an increased resistance to the passive movement of a joint which is constant throughout the range of joint motion, and not related to the speed of joint movement. Seen in Parkinson's disease. ...Read more
See below: It is mostly the quality of the movement. With rigidity, the muscle tone stays pretty much the same when someone moves the limb, there is constant resistance to movement. It has also been called "lead pipe" rigidity. In spasticity, there is initial resistance to movement and then the resistance gives way. This is called "clasp-knife" spasticity. Rigidity is often seen in parkinsons. ...Read more
None: Not quite sure what you mean by muscle wall rigidity, muscles do not have "walls". They are made of bundles of muscle fibers and the bundles are encased in strong elastic tissue called fascia. They have to increase in diameter as they contract, and then relax back to the original shape as they lengthen. A rigid wall would prevent shape changes. Swollen muscles can feel like there's a rigid wall. ...Read more
This is abnormal: Rigidity is an involuntary response to an injury or other abnormal situation. Muscle tone or firmness is a different situation. You can develop muscle tone and firmness by working muscles as with exercise. ...Read more
The skeletal system.: The bones of the skeletal system provide the structure and rigidity. Crustaceans in the seas, however, are soft on the inside and have outer shells to provide this same structure and rigidity. ...Read more
