Direct-type cavus foot deformities are most commonly encountered and are primarily sagittal plane deformities. Direct deformities should be delineated from rarer triplane pes cavovarus deformities. The lateral weight-bearing radiograph is the cornerstone of imaging evaluation of direct pes cavus foot deformity. The apex of Meary talo-first metatarsal angle on the lateral radiograph represents the pinnacle of the cavus deformity and assists in subclassification of the deformity. With routine application, ancillary radiographic imaging techniques, such as the modified Saltzman view or the modified Coleman block test, can give valuable insight into deformity assessment and surgical planning.
直接型马蹄内翻足畸形最为常见，主要为矢状面畸形。直接畸形应与罕见的三平面马蹄内翻足畸形区分开来。侧位负重位 X 线片是直接型马蹄内翻足畸形影像学评估的基石。侧位 X 线片上 Meary 距跟第一跖骨角的顶点代表了内翻畸形的最高点，并有助于对畸形进行亚分类。通过常规应用辅助影像学检查技术，如改良 Salzman 位或改良 Coleman -block 试验，可对内翻畸形的评估和手术计划提供有价值的信息。
