Abstract：
UNASSIGNED: If not corrected, the first metatarsal pronation rotation deformity is deemed responsible for the high hallux valgus (HV) deformity recurrence rate. Its correction method by osteotomy and arthrodesis has been recommended, just like the metatarsus primus varus (MPV) deformity correction. Since the pathogenesis of the first metatarsal pronation is not well understood, there may be other surgical approaches to correct it.
UNASSIGNED: A 53-year-old female\'s HV feet presented with severe left hallux pronation, and positive radiological round head and inferior tubercle shift signs of the first metatarsal. She underwent a non-osteotomy non-arthrodesis soft-tissue procedure that was expected to correct the MPV deformity but not the pronation deformity. Post-operative hallux pronation was reversed, and round head and inferior tubercle signs were corrected.
UNASSIGNED: The first metatarsal hypermobility and displacement of HV feet are probably in all three planes. Correction of MPV in the first metatarsal entirety in the transverse plane without osteotomy or arthrodesis can also induce a correction effect on its sagittal and frontal planes.

摘要：
■如果未更正，第一跖骨旋前旋转畸形被认为是高外翻（HV）畸形复发率的原因。建议采用截骨术和关节固定术的矫正方法，就像meta骨发膜内翻（MPV）畸形矫正一样。由于第一跖骨旋前的发病机制尚不清楚，可能还有其他手术方法来纠正它。
■一名53岁的女性HV双脚出现严重的左外翻，第一跖骨放射学阳性圆头和下结节移位征象。她接受了非截骨非关节固定术软组织手术，有望纠正MPV畸形，但不能纠正内旋畸形。术后外翻逆转,圆头和下结节征得到纠正。
■HV脚的第一meta骨过度活动和位移可能在所有三个平面中。在不进行截骨术或关节固定术的情况下，在横向平面上矫正第一meta骨的MPV也可以对其矢状和额面产生矫正作用。
