Valgus malalignment can be corrected with a biplanar lateral opening wedge distal femoral osteotomy (bLOWDFO) in patients with symptomatic lateral compartment disease. Advantages of a lateral opening wedge technique over the medial closing wedge technique include avoidance of vascular structures and theoretically better control of the amount of correction. The advantages of a bLOWDFO over a uniplanar osteotomy are that it creates a larger surface area for healing, and provides inherent stability to control the osteotomy intraoperatively. The purpose of this article is to present a reproducible technique for bLOWDFO and review the indications, preoperative planning, rationale, and clinical outcomes.
对于有症状的外侧间室疾病患者,外翻畸形可通过双平面外侧开口楔形股骨远端截骨术(bLOWDFO)进行矫正。外侧开口楔形技术相对于内侧闭合楔形技术的优势包括避免血管结构,并且理论上能更好地控制矫正量。bLOWDFO相对于单平面截骨术的优势在于它能创造更大的愈合表面积,并在术中提供内在稳定性以控制截骨。本文的目的是介绍一种可重复的bLOWDFO技术,并回顾其适应症、术前规划、原理和临床结果。
