Abstract

A new swelling copolymeric material suitable for self-anchoring bone implants was introduced in part I of this two-part article. The main goal in the second part of the study was to investigate the in vitro fixation characteristics of these novel implants in bone using push-out mechanical testing. Specifically, we examined the various factors that influence the in vitro fixation levels achieved by these anchors and identified a range of copolymer compositions that provide good fixation characteristics for these implants. The factors studied included the copolymer composition, presence of AS-4 carbon fiber reinforcement, and the time of implantation (in an environment of saline solution). The push-out tests were conducted on smooth cylindrical plugs of the swelling materials that were implanted in bovine cortical bone. The bone-implant system was then immersed in saline solution for various periods of time ranging from 1 to 28 days prior to push-out testing. The refixation characteristics of the implants were also investigated in this study by performing repeated push-out tests on a single implant without completely dislodging the implant from the bone. Holding strengths comparable and often exceeding many current orthopedic fix...Continue Reading

Angelman Syndrome

Angelman syndrome is a neurogenetic imprinting disorder caused by loss of the maternally inherited UBE3A gene and is characterized by generalized epilepsy, limited expressive speech, sleep dysfunction, and movement disorders. Here is the latest research.
