A common pediatric fracture is often overlooked due to the subtle deformity of the proximal first metatarsal. The injury is produced during a fall from a height, resulting in a flexion force that wedges the oblique first cuneiform-first metatarsal epiphysis into the first metatarsal-second metatarsal interspace. The injury is more severe than indicated by the bone injury, in that ligaments are involved in subluxation. Anatomic features of the first metatarsal-first cuneiform area present a suitable site for the described injury to occur. The pathogenesis of adult Lisfranc tarsometatarsal dislocation is the model for the pediatric equivalent. The clinical, physical, and radiologic findings of 16 patients are reviewed.
一种常见的儿童骨折常因第一跖骨近端的细微畸形而被忽视。这种损伤是在从高处跌落时产生的，导致一种屈曲力，使斜形的第一楔骨 - 第一跖骨骨骺楔入第一跖骨 - 第二跖骨间隙。该损伤比骨骼损伤所显示的更为严重，因为韧带也参与了半脱位。第一跖骨 - 第一楔骨区域的解剖特征为所述损伤的发生提供了合适的部位。成人Lisfranc跗跖关节脱位的发病机制是儿童相应损伤的模型。本文回顾了16例患者的临床、体格检查和影像学检查结果。
