Abstract: Methods and kits are provided to treat scapho-lunate ligament tears, which involve stabilization of the scaphoid and lunate both dorsally and volarly. The treatments can be performed through open, mini-open or arthroscopic procedures, as an intra-capsular or extra-capsular repair and stabilization procedure. The treatment procedures involve the use of sutures or wires to fix the relative orientations of the scaphoid and lunate, and the optional use of bone anchors or other bone attachment devices to create a capsulodesis between the lunate and scaphoid, or other bones, to lift the scaphoid into the desired position. Localization of the entry point of the sutures or wires into the bones are used to improve positioning of the bone anchors, sutures and wires.

Abstract: Provided herein are trans-abdominal gastric systems and related methods that are useful in a range of applications for accessing internal regions of a patient. A cannula has internal and external anchors to reliably secure the anchor to an abdominal wall of the patient. An introducer with a capture element facilitates system placement by retrograde introduction. Upon completion, the system is removed and the gastric and abdominal wall incision and defect closed by sutures specially connected to the system that ensures reliable system removal and suture closure in a configuration that is outside the abdominal wall. The systems and methods are particularly suited for use with conventional laparoscopic or endoscopic medical instruments.

Abstract: A method and system for performing a total joint arthroplasty procedure on a patient's damaged bone region. A CT image or other suitable image is formed of the damaged bone surfaces, and location coordinate values (xn,yn,zn) are determined for a selected sequence of bone surface locations using the CT image data. A mathematical model z=f(x,y) of a surface that accurately matches the bone surface coordinates at the selected bone slice locations, or matches surface normal vector components at selected bone surface locations, is determined. The model provides a production file from which a cutting jig and an implant device (optional), each patient-specific and having controllable alignment, are fabricated for the damaged bone by automated processing.

Abstract: A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.
