Abstract: A core training apparatus for the golf swing. A semicircular member is coupled with a support member, and a resistance member is connected to one of the coupling points. The resistance member is secured to a fixed point, and the user rotates the apparatus back and forth with the user standing at the center rotational axis of the semicircular member, with the resistance member being guided along the semicircular member. The back-and-forth rotation acts to increase and decrease tension on the resistance member thereby exercising the core of the user.

Abstract: Surgical methods for stabilizing a joint are disclosed. The methods aid in surgical repairs by allowing for quick and reproducible repairs to be made. A bone tunnel is formed anteriorly/posteriorly in clavicle, and a bone tunnel is formed superiorly in acromion. At least one cannulated insert is provided into one or both of bone tunnels to protect the bone from abrasions caused by a flexible construct. A flexible construct is passed through the acromion tunnel and the clavicle tunnel. An attachment device may then be positioned on at least one side of the clavicle and/or acromion tunnel, and the flexible construct is attached to the attachment device.

Abstract: A bioabsorbable interference screw having a tapered profile which extends along substantially the entire length of the screw. The tapered profile makes the screw easy to insert while providing superior fixation resulting from a progressively increasing diameter. Upon insertion, the screw engages cortical bone at the back end of the bone tunnel and fills all but 5-10 mm. of the tunnel, thereby providing increased fixation strength while also promoting fast healing. The screw includes a head provided with a specially designed drive socket with radially extending slots at its outer end for receiving corresponding protrusions on the shaft of screwdriver. The drive socket optimizes the torque capacity of the screw. To maintain wall thickness, the socket has a taper corresponding to the tapered outer profile of the screw. The taper of the socket also permits easy insertion of the tip and shaft of the driver into the screw.

Abstract: A variable tilt angle shoulder prosthesis includes a variable tilt angle, comprising a head component including a proximal portion configured to interface with a glenoid process and a distal surface including a socket depression defined therein; a humeral shaft; a humeral neck at the end of the shaft including a proximal ball end which is configured to couple with the socket depression of the humeral head as a ball-in socket joint, adjustable, upon coupling with said humeral neck, to a selected tilt angle among a plurality of tilt angles relative to an elongate direction of said shaft to substantially match said prosthesis to a natural tilt angle of a humeral head of a patient.

Abstract: A shoulder arthroplasty apparatus includes a stemless humeral head for coupling to a previously cut humeral surface. The base of the humeral head has a stabilizing base extension that is impacted into a cancellous region of the cut humeral surface. A preferred base extension has a cruciform shape including two planar fins intersecting at or near the center of the base. The periphery of the humeral head is formed to match the cortical margins of the cut humeral surface. The humeral head is preferably cemented or press-fit to the humeral surface. The humeral head has any of a range of peripheral shapes and sizes matching the specific shape and size of the anatomic neck of a humeral surface. A method for performing the shoulder arthroplasty includes a new surgical approach using a guide to cut accurately and safely on the anatomic neck of the humerus and another guide to properly orient the reaming of the glenoid.

Abstract: The present invention provides a golf exercise apparatus that includes a resistance such that during an exercise emulating a golf swing, muscles of the axial skeleton and lower extremities of a golfer are strengthened. The golf exercise apparatus includes a support base, an axial shaft coulpled to the support base, and means for resisting the muscles of the golfer during the golf swing when the golfer is coupled with the shaft of the exercise apparatus. The golf exercise apparatus preferably provides progressive resistance to the muscles of the golfer during a downswing of the golfer. The support base preferably comprises at least one end having a reverse bevel such that the support base is securable under a closed door by wedging the end having the reverse bevel under the door. Alternatively, a support frame is coupled to the support base by wedging the end having the reverse bevel with the frame.

Abstract: A surgical implant for securing ligament grafts into a joint. The implant has back-biting threads that allow the implant to be advanced into bone by impaction. If necessary, the implant can be removed from the bone by rotation. The implant is used, for example, for knee ligament repair by forming a longitudinal socket in a bone. The socket is intersected by a transverse pin. A flexible strand is drawn with the pin through the bone. A looped portion of the flexible strand is diverted so as to protrude out of the entrance to the longitudinal socket. The ends of the flexible strand remain accessible on either side of the bone. The ligament graft is captured within the strand loop protruding from the entrance to the socket. The strand is retracted into the socket, drawing the graft into the socket by pulling on the accessible ends of the flexible strand. The graft is fixed in the socket using the transverse implant.

Abstract: A limb positioning apparatus utilizing a structural member having a compartment with an opening thereto. The structural member is supported at a predetermined position relative to the limb and at a certain distance from the limb. A first line is linked or attached to the limb and connected to a constant force spring located within the compartment of the structural member. A second line is attachable to the limb and is also connected to a constant force spring lying within the compartment of the structural member. The forces exerted by the first and second constant force springs are applied cumulatively or alternatively to provide a pre-determined tension force on the limb of the patient.

Abstract: A double-forked arthroscopic tool is provided for inserting a looped, double strand of semitendinosus tendon into the femoral tunnel during ACL reconstruction. The double strand of tendon is fixed in the tunnel by a transverse implant, which passes just under the apex of the looped tendon, such that the tendon is securely looped over the implant in the femoral tunnel.

Abstract: A prosthetic glenoid for use in the shoulder is comprised of a cup having three flanges. To prepare the shoulder for implantation of the cup, the glenoid fossa is reamed to a depth at which the acromion, coracoid, and lateral portion of the scapula form a tri-flanged configuration. The cup is proportioned to be positioned in the reamed glenoid fossa such that each of the three flanges of the cup corresponds to one of the three bones forming the tri-flanged configuration of bone.

Abstract: A tendon leader used in knee surgery utilizing an elongated stem member. The stem includes a leading end and a trailing end. A tendon engaging tube is held to the stem for guiding placement of a tendon in a knee.

Abstract: A ligament repair kit and procedure for installing a cannulated bone screw and ligament washer to retain ligament at a bone site using a first cannula in conjunction with selected obturators to engage and relocate ligament and in conjunction with a drill bit to drill a bone hole for anchoring, and using a second larger cannula with a driver to screw a bone screw into the bone hole retaining the relocated ligament at the anchoring site.

Abstract: A tendon stripper and leader set for stripping a tendon to a select diameter and engaging the stripped end with a tendon leader sized to the stripped tendon for positioning the tendon during bone attachment or other procedures. The tendon stripper is formed as an elongated tool with a handle, a long slender neck and a tip having a coiled eyelet with a stripping edge and a side entry slot, the tendon leader comprising an elongated semirigid leader with a woven expandable end sized to enlarge over the end of a stripped tendon on installation and contract around the tendon during tension for relocating the tendon.
