摘要：
A forced growth axial growing spine device includes a central body portion having opposing ends. At least one housing is disposed at one end of the central body portion. The at least one housing includes a locking mechanism. At least one rigid member is coupled to the central body portion. The locking mechanism allows the rigid member to translate in one direction and inhibits translation of the rigid member in an opposing direction. Additionally, the central body portion includes a cam and at least one port. One or more ball bearings may be inserted into the ports. Operation of the cam in conjunction with the ball bearing urges the rigid member away from the cam, thereby increasing an overall length of the forced growth axial growing spine device.
