Design and Technology for ACCORD◊ Cable System
Effectiveness of an orthopaedic cable is measured by its strength and resistance to fretting. Many cables are made of seven bundles of seven strands each (Figure 1). However, the ACCORD Cable System contains 19 bundles of seven strands each (Figure 2) which gives it up to four times the fatigue life of previous 7x7 cable designs.1 Also, the 19x7 configuration makes the ACCORD Cable System more flexible, so it can be positioned easily.1
The ACCORD Cable System is an efficient system - primarily because it allows a clamped cable to be loosened and retightened. Other cable systems employ a crimp that deforms the cable and can only be used one time. With the ACCORD Cable System, you can simply unlock the clamp, reapply tension to the cable, and clamp the cable again.
The ACCORD Cable System offers multiple options. Titanium trochanteric grips come in two sizes and in four lengths for a total of eight options. The “small” and “standard” sizes represent the portion of the grip that captures the trochanter and they are based on anatomic studies of actual femurs. ACCORD grips also come in four lengths (allowing for 3, 5, 8 and 11 cables). Trials are also available to help you determine which trochanter size will be needed. There are also three sizes of titanium plates (150, 200 and 250mm) that can be used with the cobalt chrome cables. For trauma situations. ACCORD Cable System includes stainless steel cables, screws, and spikes.
