Pectus excavatum

(Page 2)

There are other types of OI, but they occur very infrequently and most are considered subtypes of the moderately severe form (type IV).

Complications are largely based on the type of OI present. They are often directly related to the problems with weak bones and multiple fractures.

Complications may include:

• Hearing loss (common in type I and type III)
• Heart failure (type II)
• Respiratory problems and pneumonias due to chest wall deformities
• Spinal cord or brain stem problems
• Permanent deformity

Severe forms are usually diagnosed early in life, but mild cases may not be noted until later in life. Make an appointment with your health care provider if you or your child have symptoms of this condition.
