The authors describe a new surgical technique for the correction of a hallux abducto valgus deformity. The crescentic "shelf" osteotomy combines a dorsal-to-plantar crescentic osteotomy with a medial-to-lateral transverse osteotomy at the first metatarsal base. This technique allows triplanar correction, stable open reduction with internal fixation, and precise intermetatarsal reduction. This article discusses alternate base osteotomies, anatomical considerations of the first metatarsal, and data predicting frontal and sagittal plane motion of the distal fragment. Also included is a procedural guide followed by examples and possible complications. An analysis of 22 procedures are presented. The article briefly introduces the capital crescentic shelf osteotomy with review of the procedure.
作者描述了一种用于矫正拇外翻畸形的新手术技术。新月形“骨嵴”截骨术结合了第一跖骨基底从背侧到跖侧的新月形截骨术和从内侧到外侧的横向截骨术。该技术允许进行三平面矫正、稳定的切开复位内固定以及精确的跖骨间复位。本文讨论了替代的基底截骨术、第一跖骨的解剖学考虑因素以及预测远端骨折块额状面和矢状面运动的数据。还包括一份手术指南，随后是实例和可能的并发症。展示了对22例手术的分析。本文简要介绍了新月形骨嵴截骨术并对手术过程进行了回顾。
