“…In contrast, the results of the present study reveal no statistically significant correlation between BMD and biomechanical stability of variable locking plate fixation. These findings correspond to findings of other studies investigating plate fixation [29,32,35]. In conclusion, based on the results of the present study we consider variable locking plate fixation superior to single screw fixation concerning biomechanical stability for proximal chevron osteotomy.…”

“…However, the donor age is similar to other biomechanical studies which focus on the comparison of surgical methods for hallux valgus reconstruction [34][35][36]. Also, due to the relatively high donor age, BMD shows lower values than in some comparable studies [20,29].…”

Purpose The proximal chevron osteotomy provides high correctional power. However, relatively high rates of dorsiflexion malunion of up to 17 % are reported for this procedure. This leads to insufficient weight bearing of the first ray and therefore to metatarsalgia. Recent biomechanical and clinical studies pointed out the importance of rigid fixation of proximal metatarsal osteotomies. Therefore, the aim of the present study was to compare biomechanical properties of fixation of proximal chevron osteotomies with variable locking plate and cancellous screw respectively. Methods Ten matched pairs of human fresh frozen cadaveric first metatarsals underwent proximal chevron osteotomy with either variable locking plate or cancellous screw fixation after obtaining bone mineral density. Biomechanical testing included repetitive plantar to dorsal loading from 0 to 31 N with the Results The variable locking plate construct reveals statistically superior results in terms of bending stiffness and dorsal angulation compared to the cancellous screw construct. There was a statistically significant correlation between bone mineral density and maximum tolerated load until construct failure occurred for the screw construct (r=0.640, p=0.406). Conclusion The results of the present study indicate that variable locking plate fixation shows superior biomechanical results to cancellous screw fixation for proximal chevron osteotomy. Additionally, screw construct failure was related to levels of low bone mineral density. Based on the results of the present study we recommend variable locking plate fixation for proximal chevron osteotomy, especially in osteoporotic bone.

“…Promising results could be achieved with the use of the plantar plate for TMT I arthrodesis [12,16]. In a biomechanical study Marks et al described a clear advantage of the plantar osteosynthesis with a one-third tubular plate over a screw osteosynthesis in neuropathic feet [11].…”

Plantar versus Dorsomedial Locked Plating for Lapidus Arthrodesis: A Biomechanical Comparison

Abstract: Plantar plating appears to offer biomechanical benefit. Clinical studies will be required to show whether this translates into earlier resumption of weightbearing and into lower rates of nonunion.
