内生软骨瘤病的特点是发生于下肢长管状骨的骨骺和干骺端的单侧内生软骨瘤,此病损广泛起源于生长板闭合前的骨骺内,并直接蔓延过骨骺生长板到干骺端,造成肢体严重不等长、成角畸形、未成熟长骨不对称性生长停滞及关节不对称。研究对象为8例患儿(5男3女),初诊时平均年龄5.8岁,均无 Endochondromatous disease is characterized by unilateral endochondromas of the bone and metaphyseal end of long tubular bones of the lower extremities. This lesion originates extensively in the epiphyseal bone before the growth plate is closed and directly spreads over the epiphyseal growth plate to dryness. Sputum, resulting in severe limb length, angular deformity, immature long bone asymmetry growth stagnation and joint asymmetry. The study population consisted of 8 children (5 men and 3 women). The average age at the time of initial diagnosis was 5.8 years old.
