Apparatus for alignment of knee arthroplasty tibial cutting block

摘要

The apparatus comprises a femoral trial component 1 having means (4, fig 1) to releasably attach an extension arm 5 having a distal end 6. In use, this distal end is used to locate a tibial cutting block (7, fig 3). Once the cutting block is releasably attached to the tibia the extension arm can be removed. The device may also comprise locating lugs 9 through which an alignment rod 8 may be located. The alignment rod may also releasably engage an ankle halter (10-11, fig 4), the halter being configured to allow traction to the lower leg during realignment.
