: Distal chevron metatarsal osteotomy bunionectomy is a commonly performed procedure for the treatment of mild to moderate hallux valgus. We continue to use the intraosseous sliding osteotomy plate system for fixation of the distal metatarsal osteotomy. With the addition of the Akin osteotomy, we are able to obtain reliable, reproducible correction with better cosmesis and increased patient satisfaction for more advanced deformities.
: We prospectively evaluated 138 (145 feet) consecutive patients who underwent double osteotomy bunionectomy using the intramedullary plate system and 3.2-mm cannulated screw system. The senior author performed all operative procedures. Patients were evaluated preoperatively, postoperatively, and at the final follow-up using the American Orthopaedic Foot & Ankle Society (AOFAS) forefoot scoring system.
: All osteotomy sites of operatively corrected feet healed. There were no hardware failures. A small number of patients complained of stiffness and pain related to the hardware. All patients dramatically improved their AOFAS scores compared with preoperative values. The hallux valgus angle was corrected by a mean of 17.3 degrees (range, 10 to 20 degrees), and the intermetatarsal angle was corrected by a mean of 6.8 degrees (range, 5 to 9 degrees).
: Chevron osteotomy paired with an Akin osteotomy (double osteotomy bunionectomy) resulted in excellent function and pain relief. We continue to recommend the use of the intramedullary plate system and 3.2-mm cannulated screw system because of its low profile, reliability of fixation, and relative ease of use.

对于轻度至中度拇外翻，跖骨远端 Chevron 截骨术合并囊炎切除术是一种常用的治疗方法。我们继续使用骨内滑动截骨钢板系统固定跖骨远端截骨术。通过增加 Akin 截骨术，我们能够获得可靠、可重复的矫正效果，改善美容效果，提高更严重畸形患者的满意度。
我们前瞻性评估了 138 例（145 足）连续接受髓内钢板系统和 3.2mm 空心螺钉系统双截骨术合并囊炎切除术的患者。高级作者进行了所有手术操作。患者在术前、术后和最终随访时使用美国矫形足踝协会（AOFAS）前足评分系统进行评估。
所有手术矫正足部的截骨部位均愈合。无内固定失败。少数患者因内固定物出现僵硬和疼痛。与术前相比，所有患者的 AOFAS 评分均显著提高。拇外翻角平均矫正 17.3 度（范围 10 度至 20 度），跖骨间角平均矫正 6.8 度（范围 5 度至 9 度）。
Chevron 截骨术加 Akin 截骨术（双截骨术合并囊炎切除术）可获得良好的功能和缓解疼痛。我们继续推荐使用髓内钢板系统和 3.2mm 空心螺钉系统，因为其具有低轮廓、固定可靠和相对易用的特点。
