摘要： A device for guiding a drilling of a femoral head of a femur in femoral head resurfacing comprises a body defining a guide channel adapted to receive and guide a drilling component therein. Arms are pivotally connected to the body and biased toward one another, the arms each having a contact end extending below the body, the contact ends adapted to contact a femoral neck when the body is in a hovering position relative to the femoral head. Sensors produce a signal indicative of an orientation angle of each of the arms relative to the body. A processor unit calculates the orientation angles of the arms from the signal, and evaluates from the orientation angles an alignment of the body relative to the femur. A visual output produces a visual signal representative of said alignment. A method for aligning a drill guide device on a femur for subsequent drilling a femoral head with a guide channel in the drill guide device is also provided.

摘要： A device for performing a surgical procedure on a knee includes an adjustable femoral portion, a tibial portion and at least one sensor coupled with the femoral and/or tibial portions to sense pressure exerted by the femoral and tibial portions against one another. The femoral portion is adapted for removably coupling with a distal end of a femur to adjust tension in soft tissue adjacent the knee and has at least one positioning feature adapted to move relative to the distal end of the femur as the femoral portion is adjusted, thus helping position a femoral prosthetic on the distal end of the femur. The sensor(s) may be adapted to sense pressure at medial and lateral sides of the knee, and relative pressures may be displayed as data on a visual display. Adjustments to the femoral member may be made to balance pressure at flexion and extension of the knee.

摘要： Systems, devices, and methods are provided for measuring forces in the space of a knee during surgery. Such forces can be caused by tension in the ligaments of the knee. A femoral member is engaged with a distal femur. While the knee is flexed, partially extended, or fully extended, a force sensor and a gauge shim can be placed in the gap between the femoral member and the tibial plateau to measure the forces therebetween. The force sensor provides an accurate and quantifiable measurement of force, making knee replacement surgery and ligament tension balancing more accurate, standardized and repeatable. The force sensor comprises an elongate housing which comprises a thin force sensing distal portion and a proximal handle portion.

摘要： A method for aligning a bone cutting guide on a tibia may involve coupling a cutting guide alignment device and an attached cutting guide with a tibia, adjusting the alignment device in a varus/valgus orientation, adjusting the alignment device in an anterior/posterior orientation, attaching the cutting guide to the tibia, and removing the alignment device from the cutting guide, leaving the cutting guide attached to the tibia. The adjustments to the alignment device may be made according to vertically and horizontally oriented laser lights emitted from the alignment device. As the alignment device is adjusted, the bone cutting guide attached to the alignment device changes position relative to the tibia.
