A contoured locking plate for distal fibular fractures in osteoporotic bone: A biomechanical cadaver study

Comparison of modern locked plating and antiglide plating for fixation of osteoporotic distal fibular fractures

“…The impetus for the locking plate used in our study was to provide increased fixation in the distal fragment and compare it to antiglide plating. The data in this study, and in the study by Zahn et al infers that the construct is biomechanically strengthened with the increased number of distal locking screws [7]. This increased construct stiffness may provide superior stability at the fracture site during healing, but we do not believe it would change the long-term biomechanics at the ankle joint after fracture union.…”

“…Minihane et al demonstrated superiority of antiglide plating to lateral locked plating [4], however, in the lateral locked plate group, there were only two screws placed distal to the fracture. Since that study, newer periarticular plates have been developed, and Zahn et al has described an anatomically contoured laterally based periarticular locking plate with four 2.7 mm distal locking screws to be biomechanically stronger than a non-locking laterally based anatomically contoured plate [7]. The impetus for the locking plate used in our study was to provide increased fixation in the distal fragment and compare it to antiglide plating.…”

“…Prior studies demonstrating the superior function of posterolateral non-locking antiglide fixation, such as that by Minihane et al, utilized a locking one third tubular plate in their comparison, which only provided two points of fixation in the distal segment [4]. However, more recently Zahn et al have shown that anatomically contoured distal fibular locking plates are biomechanically superior to non-locking lateral plates in a cadaveric model [7]. By increasing the distal fixation with modern locked plating, this may decrease the rate of peroneal irritation while providing a construct that may exhibit biomechanical superiority, especially in patients with poor bone quality.…”

Effective combination of bone substitute and screws in the jail technique: a biomechanical study of tibial depression fractures

“…They were harvested from fresh-frozen cadavers and the bone mineral density was determined by quantitative computer tomography (pQCT; Stratec Inc., XCT2000, Pforzheim, Germany) [5][6][7]. All specimens clearly showed a loss of the metaphyseal spongiosa as in osteoporotic bones.…”
