Magnet for Pectus Excavatum treatment

Pectus excavatum is a congenital disorder which causes the chest to have a sunken or “caved in” appearance. It is the most common congenital chest wall abnormality in children.

For more than 50 years, pectus excavatum has been corrected by major surgical reconstruction through the use of either the Nuss or Ravitch procedures. Both of these procedures require big operations and hospitalization for pain management.

In an effort to make the pectus excavatum operation better for patients and their families, surgeons at UCSF have developed a novel method to correct the pectus excavatum chest wall deformity. With the Magnetic Mini-Mover Procedure (3MP), the deformed costal cartilage is gradually reformed by a controlled gradual outward “pull” on the depressed breastbone. This is achieved with only minimal surgery and without the need for painful implanted chest wall struts.

Two magnets, one inside the chest and the other outside the chest, are used to create a magnetic force field which applies a controlled sustained force. The goal is to promote the rib cartilage to move to a more normal position. This results in a more gradual correction of the chest wall over a period of months using nominal force-this is the same principle used in moving teeth with orthodontic braces. (adapted from Pediatric surgery UCSF.. link)
