［Objective］To explore the clinical efficiency,operative methods,apparatus assembly and postoperative administration of Ilizarov technique in the correction of talipes equinovarus.［Method］From January 2003 to May 2006,32 patients were corrected with QIN Si-he's orthotics devices on the Ilizarov principle of tension-stress,which involved 15 males and 17 females,the age ranged from 10 to 25 years.

［目的］探讨Ilizarov技术矫正马蹄内翻足畸形的手术方法及器械改良、术后管理方法的改进及疗效［方法］2003年1月～2006年5月，根据Ilizarov张力应力法则，应用秦泗河改良的外固定矫形器，遵循Ilizarov穿针固定的基本原则，共手术治疗马蹄内翻足32例，男15例，女17例；年龄10～25岁，平均17岁。

The experimental result shows that after reclaiming the tailings with garbage fertilizer, Leucaena leucocephala Dewit. can grow well on the tin-zinc tailings pond while it is restricted in the tailings ponds without any reclamation; the contents of As, Pb and Zn in Leucaena leucocephala Dewit. are not high, only a little above those in normal plants.

试验结果表明：在用垃圾肥对尾砂进行改良之后，银合欢能在锡锌尾砂库上较好地生长，而在未经过任何改良的纯尾砂库上则明显受到抑制；银合欢不同组织中的As、Pb、Zn含量均不高，仅略高於一般植物的背景值。

Methods 49 cases with unilateral cleft lip were repaired on modified Millard's method. These ways include: The improved type"Ⅰ"didn't make cut under the anterior naris;the distinction between the wet and dry vermilion of the lip, and the application in the operation; closed in the wound near at pyriform aperture edge by"L-flap"and"M-flap"; relaxed alae nasi and made a slack cut in the nasal cavity; flexible use for"5～x"back cut and "C-flap".

对49例先天性单侧唇裂应用改良的Millard法修复：改良Ⅰ式不在患侧鼻孔下方作切口，减少了瘢痕形成；利用患侧干燥红唇组织重建健侧唇弓部分的红唇欠缺；利用小瓣&L&、&M&连同唇颊黏膜瓣来参与闭合梨状缘附近的伤口促进愈合；松解患侧鼻翼外侧脚及鼻腔内作松弛切口重建前鼻孔；灵活掌握&5～x&的返切和&C&瓣的旋转推进方向来延长唇高。
