摘要

A device (400) for positioning a bone cutting guide (432) on a tibia may- include a tibial attachment member (402) including a varus/valgus adjustment member (406), an anterior/posterior adjustment member (408), and at least one aperture for coupling with a pin inserted into the tibia. The device may also include a stationary arm (410) fixedly attachable to the tibial attachment member (402) at one end and extending to a pivot joint (412) at an opposite end. Further, the device may include a pivoting arm (414) movably attached at one end to the stationary arm (410) at a pivot joint (412). The device may also include a light emitter (416) attachable to the pivoting arm (414). A depth selection member (424) movably coupled to the stationary arm (410) and configured to removably attach to the bone cutting guide (432) can also be included in the device. A stylus (426) removably attachable to the bone cutting guide (432) can also be part of the device.
