Abstract
An orthopedic cerclage device for binding and stabilizing fractured bone segments is formed from an elongate fabric strip adapted to be tied tightly about the bone to secure the fractured bone parts together. The fabric strip has a plurality of transverse ribs raised from one face of the fabric. The strip is wrapped tightly about the bone with the ribbed surface engaging the bone. The strip is secured in place by a locking member. The primary pressure applied to the bone by the device is at the ribs so that the segments of the strip between the ribs do not adversely cut off vascular circulation in the bone. The fabric structure of the device also allows bone tissue to grow into the interstices of the device thereby incorporating it intimately into the healed bone. Also disclosed is a novel knitted fabric in which the ribs are knitted integrally into the stitch pattern of the fabric.
