一項研究將檢測使用磁鐵糾正桶狀胸，就象使用矯形器逐漸糾正牙齒一樣。

這種"磁鐵微小-移動方案"也叫做3MP，是由California-San Francisco大學(San Francisco, USA)兒童醫院的研究人員開發的。3MP使用的設備包括2部分：一種鈦包裹的磁鐵-只有1/4英寸大小，在門診隨訪的時候，手術植入兒童的胸骨上，第2塊磁鐵放置于重量很輕的塑料綁帶中，兒童在穿衣服的時候佩帶。這兩塊磁鐵之間的吸引力將綁帶定位，產生一種持續的可控制的外部拉力將骨骼、胸腔壁重新塑形。因為內部磁鐵就放置在皮膚之下，患者可以在手術當天回家，而沒有什么不舒適。根據畸形程度不同，兒童佩帶這種綁帶3-12個月。

Using Magnets to Correct 'Sunken Chest'
 
A new study will examine the use of magnets to correct sunken chest in the same way that orthodontic braces gradually realign teeth.

The "Magnetic Mini-Mover Procedure," known as 3MP, was developed by researchers at the University of California - San Francisco (San Francisco, USA) Children's Hospital. 3MP uses a device that includes two parts: a titanium-encased magnet about the size of a quarter that is surgically attached to the child's breastbone during an outpatient visit, and a second magnet embedded in a lightweight plastic brace that the child wears under clothing. The attraction between the two magnets holds the brace in place, creating a steady, controlled, outward pull on the internal magnet to reshape the bone, cartilage, and chest wall. Because the internal magnet is placed just under the skin during an outpatient visit, the child can go home on the day of the procedure with relatively little discomfort. The child wears the brace for three to 12 months, depending on the severity of the deformity.
