胫骨的缺血坏死或Blount′s病是指胫骨近侧承受内翻成角的压力,造成相关的内侧干骺端受压短缩、退变和进一步的变化。目前,儿童胚骨的Blount′s病的病因尚不明。作者观察了27例肾性骨病患者,其中11例因膝外翻就诊。11例中8例患者X线表现类似Blount′s病,均发生在胚骨近端外侧骨骺和干骺端。男5例,女3例,年龄11～20岁。典型X线表现为胫骨近侧干骺端外侧骨骺变扁伴相关的囊性变、延迟骨化和增宽。而Blount′s病胚骨近侧骨骺变化包括内侧骨骺呈鸟嘴状,相应干骺端的不规则骨化,骨骺进行性骨化甚至被受压短缩的干骺端替代,变扁宽的骺板延迟闭合,并伴受
Ischemic necrosis of the tibia or Blount’s disease refers to the pressure at the proximal tibia that undergoes valgus angulation, causing compression, degeneration, and further changes in the associated medial metaphysis. At present, the etiology of Blount’s disease in children’s bones is not known. The authors looked at 27 patients with renal osteodystrophy, of which 11 were treated with valgus. Eight of the 11 patients had similar X-ray findings to Blount’s disease, both of which occurred in the proximal epiphyseal metaphysis and the metaphysis. 5 males and 3 females, aged 11 to 20 years old. Typical X-ray showed the proximal metaphyseal tibia epiphyseal flattening associated with cystic degeneration, delaying ossification and broadening. The changes in the proximal epiphysis of the blastocyst of Blount’s disease, including the inside of the epiphyseal were beak-like, the corresponding metaphyseal irregular ossification, epiphyseal progressive ossification or compression shortening metaphyseal replacement, variable flattened epiphyseal Delayed closure of the plate, accompanied by
