Filed:

Apr 18, 2000

Appl. No.:

09/551064

Inventors:

Brian S. Schumacher - Jacksonville FL
Kevin T. Stone - Winona Lake IN

Assignee:

Walter Lorenz Surgical, Inc. - Jacksonville FL

International Classification:

A61B 1756

US Classification:

606 69, 606 70, 606 71

Abstract:

A bone distractor for distracting bone on opposite sides of an osteotomy of the bone. Included are a first affixation member for affixation to the bone on one side of the osteotomy and a second affixation member for affixation to the bone on another side of the osteotomy. A distraction element includes a screw having a rotatable member engaging the first and second affixation members for distracting the first and second affixation members relative to each other in response to rotation of the rotatable member. The first and second affixation members comprise resorbable material that is resorbed in the body after distraction is complete, thereby minimizing the size of the surgical wound required to remove the non-resorbable screw. Bone screws for affixing the affixation members to bone comprise a resorbable material, whereby the bone distractor can be explanted without explanting the bone screws.

US Classification:

606 72, 606 73, 606213

Abstract:

A clamp assembly for repairing a bone defect according to the invention includes a base, a cap opposing the base, and a post connecting the cap and the base in a fastening position on adjacent bone plate and surrounding cranium. The clamp assembly may further include an applier interacting with the post to position the cap and base in the fastening position. A method according to the invention includes placing the base and cap on opposing internal and external surfaces of the bone plate, with a portion of each of the base and cap overlapping a border of junction between the bone plate and surrounding bone. The post is rotated to bring the base and cap to the fastening position. The method may further include removing a distal portion of the post projecting from the cap and leaving a proximal portion of the post projecting from the cap and which can be deformed to secure the base and cap in the fastening position.

International Classification:

A61B 17/80

US Classification:

606 69

Abstract:

An elongated plate for coupling severed bone regions comprising at least one bridge region, the at least one bridge region terminating in at least two bone fixation regions. The at least two bone fixation regions each contain at least one aperture for receiving a suitable fastening device for securing the elongated plate to the bone regions to be coupled. The bridge region may be configured so as to be easily severed by a suitable severing device such as surgical scissors. The elongated plate and fastening device may be formed from a bio-compatible or bio-resorbable material.

US Classification:

606/070000, 606/069000, 606/073000

Abstract:

A system for mandibular reconstruction generally includes an elongated locking plate having a plurality of internally threaded apertures and a plurality of fasteners. Each fastener includes a main body portion having an upper threaded shaft and a lower threaded shaft. The lower threaded shaft is adapted to engage the mandible. Each fastener further includes a removable head portion internally threaded for engaging the upper shaft portion and externally threaded for engaging a selected one of the internally threaded apertures of the locking plate. In the preferred embodiment, the thread leads of the head portion and lower shaft of the main body portion are identical. A method of mandibular osteosynthesis utilizes the system of osteosynthesis and generally comprises the steps of temporarily securing the elongated locking plate to the mandible with at least one fastener by engaging the threads of the lower portion with the mandible and threadably engaging the head with the locking plate, unthreading the head portion from the main body of the fastener to thereby allow displacement of the locking plate from the mandible without removing the fasteners from the mandible, performing a surgical procedure (e.g., removal of a cancerous growth), and re-securing the elongated plate to the fastener with the removable head portion.

US Classification:

606/072000, 606/073000

Abstract:

A clamp assembly according to the invention can be fixed through an opening between adjacent members. The clamp assembly includes a base, a cap opposing the base, and a post connecting the cap and the base in a fastening position on the adjacent members. The post includes a torque-limiting feature to prevent over tightening of the cap and base. The clamp assembly may further include an applier interacting with the post to position the cap and base in the fastening position. A method according to the invention includes placing the base and cap on opposing internal and external surfaces of the adjacent members. The post is rotated to bring the base and cap to the fastening position, and a torque-limiting feature prevents over tightening. The method may further include removing a distal portion of the post projecting from the cap and leaving a proximal portion of the post projecting from the cap and which can be deformed to secure the base and cap in the fastening position.

International Classification:

US Classification:

606102

Abstract:

A method of implanting a hip prosthesis includes utilization of a device at the implantation site to confirm that the femoral prosthesis will have a neck length corresponding to a preoperative plan. First, a desired neck size for the femoral prosthesis is determined. Then, the femoral prosthesis is positioned in the femur. Next, a locator rod component is advanced toward the femoral prosthesis along an axis parallel to the longitudinal axis of the femoral prosthesis until a greater trochanter locator mounted on the side of the locator rod component is as close as possible to contacting the greater trochanter of the femur. Next, a neck sizing component, which has neck size markings on its outer surface, is placed on the neck projection of the femoral prosthesis. Finally, a reference distance is determined by identifying which of the reference distance markings of the locator rod component corresponds to a desired neck size marking on the neck measuring device along a line substantially perpendicular to the longitudinal axis of the femoral prosthesis. The determined reference distance should correspond to a planned reference distance that was determined in an appropriate preoperative templating and measuring procedure.

Abstract:

A method and apparatus for performing pectus excavatum repair on a deformed sternum. The apparatus includes an elongated pectus bar having a first end and a second end. The elongated pectus bar provides a minimum bendable strength of about 65 in-lbs or a minimum material yield strength of 35. times. 10. sup. 6 psi or a minimum bendable stiffness of about 1000 lb-in. sup. 2. The elongated pectus bar is shaped into a convexly curved pectus bar. The convexly curved bar is passed under the deformed sternum with the convexity facing posteriorly. The elongated pectus bar is then rotated so that the convexity faces anteriorly such that the deformed sternum is raised into a desired position.
