Tibial Punch Tower Assembly. Non-Sterile. CAT NO. 8000-1089. Howmedica Osteonics Corp., 59 Route 17, Allendale, NJ 07401. During primary Scorpio TKA procedures, the Scorpio Tibial Punch Tower (8000-1089) is used in conjunction with Scorpio Tibial Keel Punches (3760-0305/-0709/-1113 and 3761-0305/-0709/-1113) and Tibial Templates (3750-0003/-0005/-0007/-0009/-0013) to prepare the tibia for baseplate implantation. Per the surgical protocol for Duracon and Scorpio Total Knee Systems with Xcelerate Instrumentation (LSPK31 03/03), tibial templates are used to determine the appropriate coverage of the tibial plateau. Once a template size is selected, the device is secured to the plateau with fixation pins, and the tibial punch tower is assembled by placing the tower onto the two small locating pins on the tibial template. A keel punch is then selected, assembled into the channel of the tower, and impacted with a mallet. Depending on the intended implant size, several keel punches of increasing size may be utilized to incrementally enlarge the cavity. Each keel punch is advanced until it fully seats on the tibial template. Tibial preparation is considered complete when the final keel punch fully seats on the tibial template.
