儿童胫骨上段骨折较少见,但可并发膝外翻畸形。其特点是骨折线位于胫骨近侧上1/4干骺端,不波及骺板,可为青枝或完全骨折,膝外翻发生于骨折愈合后1～5个月内,呈进行性加重,一般至18个月时可停止发展。同时伴有惠肢过长畸形。其发生机理有多种学说,目前较一致的认识是由于胫骨上段血流量变化致胫骨上端不对称性生长,并与儿童发育中正常膝外翻现象有关。非手术疗法多无效。手术治疗复发率高。近年对其自然病程观察中发现多数可自行矫正或改善。 Upper tibial fractures in children is rare, but may be associated with valgus deformity. It is characterized by fracture line located in the proximal tibia 1/4 metaphyseal, does not affect the epiphyseal plate can be green branches or complete fracture, knee valgus occurred in fracture healing within 1 to 5 months, was progressive increase, Normally 18 months to stop the development. At the same time with the benefits of limb deformity. The mechanism of occurrence of a variety of doctrines, the current consensus is that the upper tibia due to changes in blood flow caused by asymmetric upper tibia growth and normal development of children with knee valgus phenomenon. Non-surgical treatment and more ineffective. Surgical treatment of recurrence rate. In recent years, most of the observation of its natural history found that they can correct or improve on their own.
