Four children are described, each with spontaneous osteonecrosis affecting nearly one-third of the lateral femoral condyle. All the children had a motor and a sensory deficit in the affected limb: two had been previously treated for neuroblastoma of the spine, one for an infected lumbar dermoid cyst and one had spina bifida. We consider that these disorders, singly or in combination, may lead to repeated excessive loading of the lateral femoral condyle, which cannot be appreciated in a knee that is not protected by normal sensation.
本文描述了4名儿童，他们均患有自发性骨坏死，累及近三分之一的外侧股骨髁。所有患儿患侧肢体均有运动和感觉功能障碍：其中2名曾接受过脊柱神经母细胞瘤治疗，1名曾接受过感染性腰部皮样囊肿治疗，1名患有脊柱裂。我们认为，这些疾病单独或共同作用，可能导致外侧股骨髁反复承受过度负荷，而在没有正常感觉保护的膝关节中，这种情况不易察觉。
