Absorbable materials in orthopaedic surgery.

The most important surgical biodegradable polymers are aliphatic polyesters of -hydroxy acid derivates. Implants made of these polymers that are currently used include sutures and fiber constructions, porous composites and drug delivery system and partially or totally biodegradable devices. Development and experimental and clinical use of absorbable devices in the fixation of fractures or osteotomies are presented. The clinical experience is based on 1,300 operated patients. The results in the fixation of cancellous bone fractures or osteotomies with absorbable implants are comparable to those of metallic implants but there is no need for removal procedures as with metallic osteosyntheses. This substantially benefits the individual as well as save money.
