Ilizarov's biology includes that, in the presence of tension and stress, both regeneration of bone and soft tissues with cellular proliferation and their biological synthesis become vigorous. The Ilizarov's external fixator has five functions namely: compression, distraction, de-angulation, derotation and translocation. The principles of this procedure include: corticotomy instead of conventional osteotomy, placement of 4-5 sets of 1.5 mm wires transfixed in the bones at different levels under tension of 70-110 kg on the circular rings without acute diastasis until the 5 th to 7th day, and then, callotasis-callus distraction. The quality and quantity of the regenerated bone within the widening distraction gap are closely related to the maximum preservation of bone marrow and periosseous blood supply, and a distraction of 1 mm per day and preferably done by 4 times 0.25 mm each time should be emphasized. Experiences in 17 cases of pseudarthrosis and unequal length of leg treated with Ilizarov's technique are presented.
伊里扎洛夫生物学理论认为，在存在张力和压力的情况下，骨和软组织的再生以及细胞增殖和生物合成都会变得活跃。伊里扎洛夫外固定器具有五项功能，即：加压、牵引、成角矫正、旋转矫正和移位。该手术的原则包括：采用皮质切开术而非传统截骨术，在无急性骨间隙的情况下，于环形支架上以70 - 110千克的张力在不同水平将4 - 5组1.5毫米的钢丝横穿固定于骨中，直至第5至7天，然后进行骨痂牵伸。牵伸间隙增宽时再生骨的质量和数量与骨髓和骨膜血供的最大程度保留密切相关，应强调每天1毫米的牵伸，最好每次以0.25毫米分4次进行。本文介绍了应用伊里扎洛夫技术治疗17例骨不连和腿长不等的经验。
