Clinical Application of Resorbable Biomaterials in Reconstructive Surgeryubt a successful procedure. Cortical bone and steel are very different materials, especially concerning the elastic properties. The elasticity constant of bone is only 1/10 of implant steel, and tensile strength is 10 times lower. In the months following internal fixation, bone substance is decreasi

Biodegradable PLA Versus Stainless Steel Intramedullary Devices for Fracture Fixation. A Comperativehes and wooden legs have been examples of simple yet meaningfull atttempts to improve body functions. As man’s knowledge and technical skill increased, so did his ability to provide more sophisticated surgical procedures and implants designed to aid the natural process of self-repair. Most implants

Einzelkonstruktionen aus dem Maschinenbau, sutures, and drug delivery systems. As-polymerized, high molecular weight poly(L-laetide) (PLLA) as synthesized according to Leenslag et al..has been successfully used for fracture fixation and orbital floor reconstruction in animals and humans.. PLLA is considered to be a fully resorbable, biocompatible material..

Die Bankkalkulation in der Praxis for 1, 2 and 3 weeks. Degradation was determined by measuring dry weight loss, mechanical properties (compression test) and SEM surface analysis. BDF 2 samples were found to degrade in such a way, that considerable weight loss was measured, fissures at material surface were observed and the specime

Further samples of the same materials were
