Stress fractures are uncommon in skeletally immature patients and usually affect adolescents involved in competitive sports, whereas they are very rare in young children. Involvement of the fourth metatarsal is very infrequent and has been associated with metatarsus adductus deformities. The authors describe a stress fracture of the proximal fourth metatarsal occurred in a 5.5-year-old child with a relapsed clubfoot. Operative correction of the deformity and cast immobilization provided consolidation of the fracture. Stress fractures of lateral metatarsals may represent a possible source of pain in recurrent clubfeet, even in young children. In these cases, early correction of the deformity is required.
应力性骨折在骨骼未成熟的患者中并不常见，通常影响参与竞技运动的青少年，而在幼儿中则非常罕见。第四跖骨受累非常少见，且与内收足畸形有关。作者描述了一例发生在一名5.5岁复发性马蹄内翻足儿童的近端第四跖骨应力性骨折。手术矫正畸形并石膏固定促使骨折愈合。外侧跖骨的应力性骨折可能是复发性马蹄内翻足疼痛的一个潜在原因，即使在幼儿中也是如此。在这些情况下，需要尽早矫正畸形。
