An implantable bone distraction device and method of using the device are disclosed. The device includes spaced first and second low profile blocks for subcutaneous implantation and attachment to osteotomically separated bone sections. The first block defines a drive chamber bore while the second block defines a threaded bore. A rotatable drive rod having a first end is received in the drive chamber bore of the first block. The rotatable drive rod's other end is threadably received in the threaded bore of the second block. The device further includes drive rod actuator located in the drive chamber bore for cooperating with the first end of the drive rod to rotate the drive rod so that one can adjust the depth to which the rod's threaded end is received in the threaded bore of the second block. This enables one to adjust the spacing between the first and second blocks, thereby enabling one to controllably distract the separated bone sections to enhance bone growth therebetween. |
