متن کاملPersistence of indentation with bioabsorbable poly-L/D-lactide versus silicone sponge scleral buckling implants.
PURPOSE To measure the amount and duration of indentation depth achieved with biodegradable poly-L/D-lactide 96/4 (PLA96) and silicone sponge implants. METHODS Thirty rabbits underwent a scleral buckling procedure. A PLA96 buckling implant was used in 15 rabbits and a silicone sponge buckling implant was in 15 rabbits. A circumferential scleral buckling implant was sutured episclerally on the...
متن کاملNew Bioabsorbable Implants for the Fixation of Metaphyseal Bone An Experimental and Clinical Study
The purpose of the present study was to investigate the suitability of bioabsorbable drawn selfreinforced polyglycolide (SR-PGA) and poly-L/DL-lactide 70:30 (SR-PLA70) implants in experimental and clinical fixations of cancellous bone osteotomies, arthrodeses and fractures. The study consists of a set of two experimental and two clinical studies, including 109 experimental animals and 87 patien...
متن کاملBioabsorbable implants in orthopaedics: new developments and clinical applications.
The use of bioabsorbable implants in orthopaedic surgical procedures is becoming more frequent. Advances in polymer science have allowed the production of implants with the mechanical strength necessary for such procedures. Bioabsorbable materials have been utilized for the fixation of fractures as well as for soft-tissue fixation. These implants offer the advantages of gradual load transfer to...
متن کاملSafety of bioabsorbable implants in vitro
BACKGROUND The aim of the present study was to investigate the safety of bioabsorbable plates and screws in humans. METHODS For this purpose, an implant system based on [poly(lactic-co-glycolic acids)(85:15)] was designed. The system was tested for pH, temperature, and swelling and then its surface morphology was analyzed for surface porosity using environmental electron microscopy. Then, the...
