20030100906, May 29, 2003

Filed:

Nov 27, 2002

Appl. No.:

10/305369

Inventors:

Richard Rosa - Short Hills NJ, US
Vernon Hartdegen - Collierville TN, US
Eric Stookey - Cordova TN, US
Brian Harris - Cordova TN, US
Robert Fencl - Cordova TN, US

International Classification:

A61F005/00

US Classification:

606/086000

Abstract:

A method of minimally invasive unicompartmental knee replacement includes accessing a knee through a minimal incision, forming a planar surface along a tibial plateau of the knee, forming a planar posterior surface along a posterior aspect of the corresponding femoral condyle, resurfacing a distal aspect of the femoral condyle to form a resurfaced area having a curved portion, implanting a prosthetic tibial component on the planar surface along the tibial plateau and implanting a prosthetic femoral component on the prepared surface of the femoral condyle formed by the planar posterior surface and the resurfaced area. The curved portion of the resurfaced area has an anterior-posterior curvature corresponding to a fixation surface of the prosthetic femoral component. Prior to implantation, the femur and tibia are prepared to receive fixation structure of the femoral and tibial components.

International Classification:

A61F005/00

US Classification:

606/086000

Abstract:

Instrumentation for use in minimally invasive unicompartmental knee replacement includes a tibial cutting guide for establishing a planar surface along a tibial plateau and a tibial stylus having an anatomic contour for controlling the depth of the planar surface along the tibial plateau. The instrumentation further comprises a posterior resection block for preparing a posterior femoral resection, with a forward portion of the posterior resection block having a configuration corresponding to the configuration of a prosthetic femoral component. Instrumentation comprising a resection block and a resurfacing guide are provided for surgically preparing a femoral condyle to receive a prosthetic femoral component. The instrumentation further includes a resurfacing guide and a resurfacing instrument for resurfacing a femoral condyle to a controlled depth. Instrumentation is provided for intramedullary alignment of femoral instruments. Also, instrumentation is provided for preparing the femur and tibia to receive fixation structure of prosthetic femoral and tibial components.

Appl. No.:

10/678701

Inventors:

Keith Raskin - New York City NY, US
Brian Harris - Cordova TN, US

International Classification:

A61B017/58

US Classification:

606/092000

Abstract:

A radially ported bone graft needle, particularly useful in minimally invasive procedures, is provided. The bone graft needle delivers bone graft material to a bone defect area by extruding the bone graft material both axially and radially simultaneously.

International Classification:

A61B 17/58

US Classification:

606088000

Abstract:

Instrumentation for surgically resurfacing a femoral condyle to receive a prosthetic femoral component in minimally invasive unicompartmental knee replacement surgery. The instrumentation includes a resurfacing guide for attachment to a femur and a rail member externally delineating an area of a femoral condyle of the femur that is to be surgically resurfaced to receive a prosthetic femoral component. The resurfacing guide has an abutment wall. The instrumentation includes a resurfacing instrument having a tissue removing surface for removing anatomical tissue from the delineated area of the femoral condyle, the tissue removing surface being movable along the delineated area to remove anatomical tissue therefrom. The resurfacing instrument has a engagement wall for contacting the abutment wall to limit the depth to which anatomical tissue is removed.
