Abstract:
The research results are inconsistent that assessing whether the increased obliquity of the distal articular surface of the medial cuneiform leads to an increase in hallux valgus angle. Thus, this study investigated the relationship between distal medial cuneiform obliquity and hallux valgus by measuring various angles in weightbearing anteroposterior radiographs of the foot. In total, 679 feet of 538 patients with the radiographs were included in the study. We measured radiographic parameters including hallux valgus angle, first to second intermetatarsal angle, metatarsus adductus angle, first metatarsus cuneiform angle, distal medial cuneiform angle, and first proximal metatarsal articular angle. The surface morphology (flat or curved) of the first tarsometatarsal joint was also recorded. Our results analysis revealed a weak negative correlation between distal medial cuneiform angle and both hallux valgus angle and first to second intermetatarsal angle, contrary to our assumption. So we believe that distal medial cuneiform angle was relatively constant and it cannot be used as a characteristic angle for quantifying hallux valgus. First metatarsus cuneiform angle was a characteristic indicator of hallux valgus and was positively correlated with its severity (p < .000), indicating that it can be used to measure the size of hallux valgus. It can also be used as a reference factor for the first metatarsal osteotomy in clinical bunion orthopedics. First tarsometatarsal joint morphology was unrelated to hallux valgus, whereas metatarsus adductus angle, and first proximal metatarsal articular angle should be considered in hallux valgus.
摘要:
研究结果不一致,无法评估内侧楔形文字远端关节面倾斜度的增加是否会导致外翻角度的增加。因此,本研究通过测量足部负重前后X线片的不同角度,探讨远端内侧楔形文字倾斜与外翻的关系。总的来说,该研究包括538名具有X光片的患者中的679英尺。我们测量了射线照相参数,包括外翻角,第一至第二跖骨间角度,meta骨内收角度,第一跖骨楔形角,远端内侧楔形文字角,和第一跖骨近端关节角。还记录了第一滑掌关节的表面形态(平坦或弯曲)。我们的结果分析显示,远端内侧楔形文字角与外翻角和第一至第二跖骨间角之间呈弱负相关,与我们的假设相反。因此,我们认为远端内侧楔形文字角相对恒定,不能用作量化外翻的特征角。第一跖骨楔状角是外翻的特征性指标,与外翻的严重程度呈正相关(p<.000),表明它可以用来测量外翻的大小。它也可以作为临床骨性愈合骨科中第一跖骨截骨术的参考因素。第一跖骨关节形态与外翻无关,而meta骨内收角度,外翻应考虑第一跖骨近端关节角。
