Foreign-body reactions to fracture fixation implants of biodegradable synthetic polymers.
Biodegradable rods of polyglycolide or lactide-glycolide copolymer were used in the internal fixation of a variety of fractures and osteotomies in 516 patients. A clinically manifest foreign-bodyExpand
Bioabsorbable polymers: Materials technology and surgical applications
Abstract Biostable and bioabsorbable biomaterials are used to manufacture implants for supporting, replacement, augmentation and guiding of growth of tissues. Bioabsorbable implants are a betterExpand
Biodegradable polylactide-glycolide copolymer implants for fracture fixation were developed and tested in rabbits. In a prospective clinical study 44 patients with a displaced fracture of the ankleExpand
Bioabsorbable fixation in orthopaedic surgery and traumatology.
Bioabsorbable internal fixation devices were introduced clinically in the treatment of fractures and osteotomies of the extremities at the Department of Orthopaedics and Traumatology, HelsinkiExpand
Outcome of clavicular fracture in 89 patients
SummaryDuring 1982, 118 patients with clavicular fracture were treated in the Department of Orthopaedics and Traumatology, Helsinki University Central Hospital. Eighty-nine patients appeared for theExpand
Ultra-high-strength absorbable self-reinforced polyglycolide (SR-PGA) composite rods for internal fixation of bone fractures: in vitro and in vivo study.
The ultra-high-strength, self-reinforced (SR) absorbable polymeric composites, consisting of reinforcement elements, like fibers, and of matrix polymer which have the same chemical elementExpand
Degradation and tissue replacement of an absorbable polyglycolide screw in the fixation of rabbit femoral osteotomies.
Degradation and tissue replacement of a totally absorbable polyglycolide screw, 4.5 millimeters in diameter and thirty millimeters in length, were studied histologically, morphometrically, andExpand
The effects of fibre reinforcement and gold plating on the flexural and tensile strength of PGA/PLA copolymer materials in vitro.
Changes in the flexural and/or tensile strength of plates and rods made of PGA/PLA copolymer submerged in water for a period of 4 wk were investigated. During this time, the effects of PGA/PLA fibreExpand
Bone changes after experimental osteotomies fixed with absorbable self-reinforced poly-L-lactide screws or metallic screws studied by plain radiographs, quantitative computed tomography and magnetic
The healing of the distal femoral osteotomy fixed with self-reinforced poly-L-lactide (SR-PLLA) or metallic screws in 16 rabbits was evaluated with plain radiographs, quantitative computed tomographyExpand
Comparison of in vitro hydrolysis, subcutaneous and intramedullary implantation to evaluate the strength retention of absorbable osteosynthesis implants.
To evaluate the behaviour of mechanical properties of absorbable osteosynthesis implants in vivo, the strength retention of self-reinforced polyglycolide rods in distilled water at 37 degrees C inExpand
