Acromioclavicular joint repair system

摘要

A system is disclosed for repairing and reconstructing a joint which has been injured by trauma, and especially an acromioclavicular joint. Means are disclosed to strengthen the repair or reconstruction and to maintain alignment while the ligaments in the joint heal, thus allowing more aggressive rehabilitation. A new joint repair tool is disclosed which is inserted into two separated bones adjacent to their respective articular joint surfaces to connect the two bones and approximate the adjacent bearing articular joint surfaces while still allowing motion between the two bones. Instruments to perform the methods are also disclosed.

主权项

1. An instrument for repairing separated bones of a joint comprising
a first component which includes means for being affixed to a first bone of a separated joint at a location spaced apart from surfaces in the joint bearing against each other, a second component which includes means for being affixed to a second bone of the separated joint at a location spaced apart from surfaces in the joint bearing against each other, and a mobile component having a length which is adjustable to a predetermined distance joined to and flexibly connecting the first and second components limiting independent movement between the first and second components and bones and allowing normal physiological motion of the bones and their joint surfaces.
