Sponge-like polymer could repair bone defects

By PlasticsToday Staff
Published: August 14th, 2014

A sponge-like polymer, polycaprolactone (PCL) shows promise as a medical material that can be used to fill gaps in human bone and serve as a scaffold to promote new bone growth. Injuries, birth defects (such as cleft palates), or the removal of tumors can create gaps in bone that are too large to heal naturally. The gaps can dramatically alter a person's appearance when they occur in the head, face, or jaw. The polymer has the potential to improve upon the two most commonly used procedures to repair these bone gaps.

Polyurethane: Form meets function

As a young architect, Frank Lloyd Wright worked for Louis Sullivan's architecture firm in Chicago. Sullivan is known for designing some of the earliest skyscrapers using steel-frame constructions. His famous adage, "form follows function," is still used by many architects who recognize the purpose of a building should be the starting point for its design. Wright later evolved the phrase to "form and function are one."
