Many methods of fixation have been used after proximal abductory metatarsal osteotomies for the correction of metatarsus primus varus. The methods include external immobilization and the application of devices such as stainless steel wire, Kirschner wires, staples, and compression plates. We have combined external immobilization with compression screw fixation across the osteotomy site. Two different types of screws were used: 1) an AO screw 3.6 mm. wide and 26 to 28 mm. long and 2) a standard Woodruff screw 3.5 mm. wide and 31.8 to 44.4 mm long. Twenty-two procedures were reviewed. When we compared the results, we found the AO screw to be superior in the degree of rigid fixation which it provides, as judged by the extent of postoperative callus formation.
在进行近端外展跖骨截骨术以矫正第一跖骨内翻后，已经使用了多种固定方法。这些方法包括外部固定以及应用诸如不锈钢丝、克氏针、U形钉和加压钢板等器械。我们将外部固定与通过截骨部位的加压螺钉固定相结合。使用了两种不同类型的螺钉：1）一枚宽3.6毫米、长26至28毫米的AO螺钉，以及2）一枚宽3.5毫米、长31.8至44.4毫米的标准伍德拉夫螺钉。回顾了22例手术。当我们比较结果时，根据术后骨痂形成的程度判断，发现AO螺钉在提供的刚性固定程度方面更具优势。
