  • Ligament balancing femoral trial
    Patent number: 9005208
    Abstract: An instrument for setting ligament tension between a distal femur and a proximal tibia has a rod mounted on a femur. The rod has an extension extending along a first axis. A first drive element is mounted on the distal femur and is rotatable about a second axis. A body is rotatably mounted on the rod extension for rotation about the first axis. The body has a second drive element engaging the first drive element and a third drive element extending about a third axis offset from the first and second axes. A ligament tensioning element is mounted on the body and has a foot for engaging a posterior condyle of a femur and has a fourth drive element. A fifth drive element engages both the third and fourth drive elements for moving the ligament balancer with respect to the body along the third axis.

  • Acetabular shell removal tool
    Publication number: 20060195105
    Abstract: A tool for separating an acetabular shell of a hip prosthesis from the surrounding pelvic bone includes a fixture which attaches to the acetabular shell and has a chisel guide mounted on it. A chisel associated with the chisel guide is curved to conform to the outer periphery of the acetabular shell, and the chisel guide causes the chisel to circumscribe the acetabular shell as the chisel is inserted between the acetabular shell and the pelvis.
