METHODS: The inclusion period was 6 months finishing in April 2021. The study analyzed the following x-ray parameters: preoperative and postoperative intermetatarsal angle (IMA), preoperative and postoperative hallux valgus angle (HVA), preoperative and postoperative coronal rotation of the first metatarsal according Hardy and Clapham\'s classification as described by Kim et al., preoperative and postoperative shape of the first metatarsal head as described by Ono et al. RESULTS: 33 patients matched our inclusion and exclusion criteria. Most patients underwent the surgery for the left foot (n = 18), compared to the right foot (n = 15). We found statistically significant differences between preoperative and postoperative IMA (p < 0.001), preoperative and postoperative HVA (p < 0.001). Preoperative and postoperative coronal rotation of the first metatarsal as classified by Hardy and Clapham was significantly different (p < 0.001), as well as preoperative and postoperative shape of the first metatarsal head (p < 0.01).
CONCLUSIONS: DROMO can correct the metatarsal rotation through minimal invasive surgery. From our perspective, DROMO technique should be another alternative for HV correction technique which in time can be associated as a local anesthetic technique, DROMO results are attractive for an ambulatory procedure.
方法:纳入期为6个月,于2021年4月结束。该研究分析了以下X射线参数:术前和术后的meta骨间角(IMA),术前和术后的外翻角(HVA),根据Kim等人描述的Hardy和Clapham分类,术前和术后第一跖骨冠状旋转。,如Ono等人所述,第一跖骨头的术前和术后形状。结果:33例患者符合我们的纳入和排除标准。大多数患者接受了左脚手术(n=18),与右脚相比(n=15)。我们发现术前和术后IMA之间有统计学意义的差异(p<0.001),术前和术后HVA(p<0.001)。根据Hardy和Clapham的分类,第一跖骨的术前和术后冠状旋转存在显着差异(p<0.001),术前、术后第一跖骨头的形态(p<0.01)。
结论:DROMO可以通过微创手术矫正跖骨旋转。从我们的角度来看,DROMO技术应该是HV矫正技术的另一种替代方法,该技术在时间上可以作为局部麻醉技术。DROMO结果对于门诊程序具有吸引力。
