Extramedullary proximal tibial guide

摘要

An extramedullary proximal tibial guide includes a distal end carrying a vertically adjustable ankle bracket as well as an ankle pointer, and a proximal end carrying a saw guide. The saw guide includes a saw guiding slot which is so configured as to have an open area between the bottom of a slot rail and portions of the top of the bone which is to be resected so that the surgeon may precisely view the location of engagement of the surgical saw with the bone structure. The surface area of engagement between the saw guide and the bone is made quite small with a sharp bone contacting edge to facilitate micro adjustment. Laterally of the saw guiding slot, side flares are provided which are designed to protect the patellar tendon and soft tissues during resection. The ankle bracket is held in place about the ankle of the patient through the use of a fastener including a ball chain and a spring. The inventive guide is provided with structures permitting the various required adjustments, which structures are recessed within the guide structure to avoid protrusions which could interfere with the surgical procedure.
