Product Overview
The M/L Taper with Kinectiv Technology allows the surgeon to fit the implant to the patient. A system of modular stem and neck components designed to help the surgeon restore the natural hip joint center intraoperatively by addressing leg length, offset, and version independently. The broad array of neck options enables the surgeon to precisely match a wide range of male and female patient anatomies without compromise.
Research has shown high variability in head height, offset and version among patients.1-3 Although the most profound differences can be appreciated between men and women, there is much variation among all patients.
Stems with modular heads and cups with modular liners have achieved widespread adoption. The system of modular necks allows the surgeon to efficiently respond intraoperatively to excessive femoral version, muscle laxity or contracture, discrepancies with x-ray templating, and unanticipated cup version, depth or height.
The intraoperative flexibility of independent leg length, offset and version allows the surgeon to:
• Equalize leg length
• Alleviate impingement
• Optimize range of motion
• Ensure optimum joint stability
The keystone to Kinectiv Technology is the exclusive use of +0 femoral heads. This allows independent adjustment of leg length and offset since all adjustments are made with the necks. Leg length is of primary concern in total joint replacement for surgeons and patients. Kinectiv Technology allows the surgeon to optimize leg length without affecting offset and conversely offset without affecting leg length.
Range of motion and joint stability is another primary issue.4,5 With the exclusive use of the +0 head, every neck has been optimized to this head length to maximize range of motion. In addition, the ante/retroverted necks allow the surgeon to intraoperatively fine tune the range of motion depending on the patient anatomy and implant position.
