The surgeon must determine the pathologic elements that need correction. Close observation for an increased HV angle, increased IM angle, pronation of the first toe, increased DMAA, enlarged medial eminence, and subluxation of the sesamoids must be performed. While there are a large number of procedures available for the management of HV, no one method sufficiently corrects all HV deformities. The upper limits of deformity correction for each procedure vary with the surgeon and their familiarity with each procedure. Ultimately, the surgeon must attempt to maintain a flexible first MTP joint and preserve the normal weightbearing pattern of the forefoot. Patient education also can be assistive in avoiding aggravating activities and making better choices in shoe wear. Tracings of the weightbearing foot and the shoe can be used to demonstrate to patients the size differences between the natural size and shape of the foot and that of the shoe, both pre- and postoperatively.
外科医生必须确定需要矫正的病理因素。必须密切观察拇外翻角度增加、跖间角增加、第一趾旋前、远端关节面角增加、内侧突起增大以及籽骨半脱位等情况。虽然有大量手术方法可用于治疗拇外翻,但没有一种方法能充分矫正所有拇外翻畸形。每种手术的畸形矫正上限因外科医生及其对每种手术的熟悉程度而异。最终,外科医生必须努力保持第一跖趾关节灵活,并保留前足的正常负重模式。患者教育也有助于避免加重病情的活动,并在鞋类选择上做出更好的决定。负重足和鞋子的描图可用于向患者展示术前和术后足部自然尺寸和形状与鞋子的尺寸差异。
