摘要：
Various surgical devices and methods for facilitating distraction of adjacent vertebrae and/or insertion of an intervertebral implant material therebetween are disclosed. The devices include an elongated barrel having a cannula. Implant materials may be inserted through the cannula. The barrel is expandable to distract the adjacent vertebrae. In one embodiment, the barrel includes a first section and a second section. In one embodiment, an inner member is reciprocally positioned within the barrel. Advancement of the inner member within the cannula causes distraction of the barrel.
