Abstract: Drill guide assemblies are adjustable for proper alignment of drill holes in the glenoid with the drill holes in the coracoid during a Latarjet procedure. The drill guide has an aimer arm extending from the body of the drill guide which has a fixed angle with respect to a drill sleeve inserted through the guide. The aimer arm can move up or down relative to the drill sleeve while maintaining the fixed angle relative to the drill sleeve by actuation of a translation member on the body.

Abstract: A strut measurement and feedback device and corresponding systems and methods for use with an external fixator are disclosed. The strut measurement and feedback device can be attached to a strut of an external fixator. The strut measurement and feedback device can confirm that the strut measurement and feedback device is attached to a proper strut to be adjusted. The strut measurement and feedback device can provide real-time feedback to an individual as the length of the strut is being adjusted to ensure the length adjustment complies with a prescription for the length of the strut. As a result, a patient can more effectively comply with the prescription as adjustments to the strut are made over time, thereby improving the likelihood of successful bone alignment.

Abstract: Implants, instruments, and methods are presented for fixing adjacent bone portions to promote fusion of the bone portion.

Abstract: Anchor delivery systems include anchors having a generally cylindrical body with a rail on top for positioning within a delivery device slot. The rail incorporates a side-bulge as a retaining feature which axially extends along a majority of the length of the rail. The bulge interferes with a corresponding hourglass cutout in the delivery device slot to prevent the anchor from stripping out of the delivery device when the delivery device is retracted through tissue. The anchors are symmetrical along a length and width to facilitate loading within the delivery device. The distal portion of the delivery device includes a series of distally-extending barbs that intentionally change the penetration force required to push the device tip through tissue.

Abstract: An anchor delivery system includes both a straight and curved drill guide along with a flexible drill, a flexible obturator and a flexible anchor inserter. The curved drill guide has a distal tip with approximately a 15° bend from the primary axis of the drill guide. Both the drill and the obturator have a reduced diameter section to improve flexibility during passage through the curved drill guide. Additionally, a surface of the inserter shaft has a laser cut pattern which permits flexing of the inserter around the inner diameter of the curved drill guide.
