摘要:


文题释义

拇外翻畸形:是指拇趾在第一跖趾关节处向外侧偏斜移位,是一种复杂的解剖畸形,一般表现为拇趾在第一跖趾关节处向外侧偏斜,关节内侧出现明显的骨赘,一些患者骨赘处软组织因长期受鞋子摩擦挤压而出现红肿、积液,严重拇外翻患者可出现其他足趾的偏斜、骑跨。
第一跖骨三维层面:截骨矫形术为目前临床治疗中重度拇外翻的主要方案,可快速纠正拇外翻畸形,恢复关节正常的生理位置,同时可促进周围肌腱、韧带等软组织的正常活动功能恢复,而跖趾关节活动依靠第一跖趾关节的匹配性,术后跖趾关节匹配性较差可能导致术后拇外翻复发,拇外翻畸形患者第一跖骨相对位置畸形结构复杂,截骨矫形术治疗中主要以第一跖骨水平面畸形作为参考。

摘要
背景:拇外翻主要通过截骨矫形进行治疗,但术后存在复发、畸形风险,因此术后评估畸形情况具有重大意义。
目的:分析拇外翻截骨矫形后第一跖骨三维层面畸形指标变化与术后功能预后的相关性,及对临床治疗的指导意义。
方法:选择2022年1-12月衡水市人民医院手足外科收治的拇外翻畸形患者100例(足),均行Scarf截骨矫形治疗。治疗前、治疗后6个月拍摄负重位足部正侧位X射线片及模拟负重位CT片,观察测量第1-2跖骨间角、足正位X射线片胫侧籽骨位置、第一跖骨旋转α角、远端关节面固角、拇外翻角,分析第一跖骨三维层面畸形量化指标之间的相关性,比较治疗前、治疗后6个月畸形量化指标及美国足踝外科协会评分的差异,并分析治疗后6个月第一跖骨三维层面畸形量化指标与美国足踝外科协会评分的相关性,评估畸形量化指标预测功能预后的效能。
结果与结论:①治疗前,拇外翻角与第一跖骨旋转α角之间无相关性(P > 0.05),与远端关节面固角、第1-2跖骨间角、足正位X射线片胫侧籽骨位置之间呈正相关(P < 0.05);远端关节面固角、第1-2跖骨间角、第一跖骨旋转α角、胫侧籽骨位置之间均呈正相关(P < 0.05);②相较于治疗前,治疗后6个月美国足踝外科协会评分明显升高(P < 0.05),畸形量化指标均减小(P < 0.05);③治疗后6个月畸形量化指标与美国足踝外科协会评分功能、疼痛、力线及总评分均呈负相关(P < 0.05);④提示第一跖骨三维层面畸形量化指标对于拇外翻畸形患者术前评估具有较高的应用价值,为临床术前评估、疗效评估提供了参考依据,以针对性展开后续治疗,降低截骨矫形后复发风险,改善预后。

Abstract: BACKGROUND: Bunion is mainly treated by osteotomy and orthopedic surgery, but there is a risk of recurrence and deformity in the postoperative period, so postoperative evaluation of deformity is of great importance. 
OBJECTIVE: To analyze the correlation of the changes in the three-dimensional deformity indicators of the first metatarsal bone after conventional osteotomy for correction of hallux valgus deformity with postoperative functional prognosis, and their guiding significance for clinical treatment. 
METHODS: One hundred patients (feet) with hallux valgus deformity in Department of Hand and Foot Surgery, Hengshui People’s Hospital were selected from January to December 2022, and all of them underwent Scarf osteotomy and orthopedic surgery. Preoperative and 6-month postoperative orthopedic X-rays of the foot in weight-bearing position and simulated weight-bearing position CT films were taken to observe and measure the intermetatarsal angle of the first and second metatarsal bones, tibial lateral sesamoid bone position on orthopedic X-rays of the foot, first metatarsal rotational α-angle, distal articular facet fixation angle, and the angle of the hallux valgus. The correlation of deformity quantifiers at the three-dimensional level of the first metatarsal bone was analyzed, and deformity quantifiers and American Orthopaedic Foot & Ankle Society scores were compared preoperatively and at 6 months postoperatively. The correlation between the quantitative index of deformity at the three-dimensional level of the first metatarsal bone and the American Orthopaedic Foot & Ankle Society score 6 months after treatment was analyzed to evaluate the efficacy of the quantitative indicators of the deformity in predicting functional prognosis.
RESULTS AND CONCLUSION: (1) Before treatment, the hallux valgus angle had no correlation with the first metatarsal rotational α-angle (P > 0.05), but was positively correlated with distal articular facet fixation angle, intermetatarsal angle of the first and second metatarsal bones, and tibial lateral sesamoid bone position on orthopedic X-ray films of the foot (P < 0.05). Distal articular facet fixation angle, intermetatarsal angle of the first and second metatarsal bones, first metatarsal rotational α-angle, and tibial lateral sesamoid bone position on orthopedic X-rays of the foot were all positively correlated (P < 0.05). (2) American Orthopaedic Foot & Ankle Society scores were significantly higher at 6 months postoperatively compared with preoperatively (P < 0.05), and the deformity quantifiers were all lower (P < 0.05). (3) There was a negative correlation of the deformity quantifiers at 6 months postoperatively with the American Orthopaedic Foot & Ankle Society score function, pain, force line, and total score (P < 0.05). (4) The quantitative deformity index of the first metatarsal bone in three dimensions is of high value for the preoperative evaluation, which provides a reference basis for clinical preoperative evaluation and assessment of the efficacy of the treatment, in order to carry out the follow-up treatment, reduce the risk of postoperative recurrence, and improve the prognosis.
