Bone block fixation by ultrasound activated resorbable pin osteosynthesis: a biomechanical in vitro analysis of stability
2010, Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and EndodontologyCitation Excerpt :However, the determined tensile forces, 80-100 N, match the results of other authors.24 Many authors applied the same experimental design, performing pull-out tests on screws.25-33 Nunamaker and Perren34 and Bluemlein et al.35,36 used small tension-measuring detectors for the measurement of axial forces on osteosynthesis screws.

2003, ArthroscopyCitation Excerpt :Good results have been reported after ACL reconstruction with hamstring grafts fixed with metallic interference screws.4 However, nonmetallic interference screw fixation has been recommended by some researchers because of concerns about potential graft laceration from metallic threads and metallic implants interfering with future knee imaging studies.7 Unfortunately, use of nonmetallic implants makes confirming the position of the implants difficult, if not impossible, on plain radiographs.
Primary stability with tibial press-fit fixation of patellar ligament graft: An experimental study in ovine knees
2001, ArthroscopyCitation Excerpt :With fixation on the cortical side, either block fracture or ligamentous rupture will occur. In their report, Tuompo et al.15 emphasized the importance of the bone block/ligament angle for the primary stability of the graft. It was shown that angulations of at least approximately 30° to 40° provided for a 3-fold load-to-failure.
Bioabsorbable polyglyconate interference screw fixation in anterior cruciate ligament reconstruction: A prospective computed tomography -Controlled study
2000, ArthroscopyCitation Excerpt :In the case of bioabsorbable screws, holding strength must be maintained up to this time despite degradation of the implant. Initial pullout strength in vitro has proved to be sufficient for most biodegradable screws.8,33,34 The CT images in our study showed bone block ingrowth between 6 and 12 weeks.
Is screw divergence in femoral bone-tendon-bone graft fixation avoidable in anterior cruciate ligament reconstruction using a single-incision technique? A radiographically controlled cadaver study
2000, ArthroscopyCitation Excerpt :ACL graft fixation in the bony tunnel is still a point of concern in knee ligament surgery and the object of intensive research. A trend toward accelerated rehabilitation programs and the use of bioabsorbable implants underlines the importance of sufficient initial early fixation.11,12,21,22 Interference screw fixation of patellar bone-tendon-bone grafts has proven to be a reliable method and has been shown to provide pullout strength exceeding that afforded by fixation with staples, cortical screws, or sutures over buttons.13,14,23
