A first ray dorsiflexion osteotomy is commonly performed for cavovarus foot correction. There are multiple techniques to fix this osteotomy, ranging from wires, screws, and plates or a combination of these. We present our results using a varisation staple (Biomet©) as an alternative fixation device. We performed a retrospective outcome analysis of a consecutive series of 10 cavovarus feet that underwent a dorsiflexion osteotomy (dorsal closing wedge) of the first metatarsal fixed with two varisation staples. The results were measured at a mean three monthly follow-ups and included union and complication rates, as well as clinical and radiographic assessment of cavus deformity correction. There was a 100% union rate with no complications or cases of delayed union. No metalwork removal was requested in any case at follow-up. First ray dorsiflexion osteotomies are most commonly fixed using a 3.5mm cortical screw. We demonstrate that our alternative and novel technique using varisation staples achieved a 100% union rate while avoiding the prominent hardware complications known to occur with cortical screws or plates.
第一跖骨背屈截骨术常用于治疗高弓内翻足。固定该截骨术有多种技术，包括钢丝、螺钉、钢板或这些方法的组合。我们展示了使用一种可变型钉（Biomet©）作为替代固定装置的结果。我们对连续10例接受第一跖骨背屈截骨术（背侧闭合楔形截骨）并使用两枚可变型钉固定的高弓内翻足进行了回顾性结果分析。结果在平均每三个月的随访中进行测量，包括骨愈合率和并发症发生率，以及对高弓畸形矫正的临床和影像学评估。骨愈合率为100%，无并发症或延迟愈合病例。随访期间，任何病例均未要求取出内固定物。第一跖骨背屈截骨术最常用3.5毫米皮质骨螺钉固定。我们证明，我们使用可变型钉的替代新技术实现了100%的骨愈合率，同时避免了已知与皮质骨螺钉或钢板相关的明显内固定并发症。
