摘要： An orthopedic screw system. The screw system comprises an outer member and an inner screw. The outer member has a longitudinal inner channel that defines an interior sidewall and is provided with screw threads on its exterior and interior sidewalls. An inner screw has threads constructed and arranged to engage with those on the interior sidewall, such that the inner screw may be secured within the inner channel. When secured within the inner channel, at least a portion of the length of the inner screw extends beyond the outer member. Methods of installing the orthopedic screw system into osteoporotic or otherwise weakened bone are also disclosed.
