Abstract: The risk of bone cement extravasation can be reduced by delivering a calcium-dependent polymerizing sealant into a bone structure prior to delivery of bone cement into that structure. The polymerization of the sealant in response to the calcium within the bone structure can fill cracks and any other potential cement leakage paths, thereby minimizing the potential for subsequent extravasation. The benefits of the use of a calcium-dependent polymerizing sealant can be provided in any procedure involving the use of bone cement, such as spinal fixation, vertebroplasty, and kyphoplasty, among others.

Abstract: Novel bone screw and plate assemblies including locking confirmation mechanisms are provided. In certain cases, a locking confirmation mechanism is operably attached to the plate, and comprises a toggling arm having an upper portion, a mid-portion and a lower portion. When a bone screw is positioned in a plate in an unlocked configuration, the locking confirmation mechanism assumes a first position. When the bone screw is positioned in the plate in a locked configuration, this causes the locking confirmation mechanism to pivot and assume a second position. The locking confirmation mechanism thus provides a convenient visual and/or tactile means to assess when the screw is in a locked configuration.
