跟腱瘢痕瓣的Z形设计和临床应用

目的设计Z形跟腱瘢痕瓣用于烧伤或外伤后的跟腱瘢痕挛缩畸形的修复.方法根据跟腱挛缩和足内翻的程度,设计Z形瓣切开的中轴位于跟腱部位的纵行挛缩线上,长8～12cm,侧臂长度5～8cm,夹角各为60°.形成的两跟腱瘢痕瓣相互沿中轴滑动以达到松解和延长跟腱.1994年3月～1999年8月临床应用7例,烧伤6例,外伤1例.结果7例均能达到踝关节功能位矫正,无一例发生瘢痕瓣缺血和坏死.结论Z形跟腱瘢痕瓣的血供丰富,挛缩的跟腱易于松解,手术安全可靠.

DESIGN OF Z-SHAPED ACHILLES TENDON SCAR COMPOSITE FLAPS TO CORRECT THE TENDON-SCAR CONTRACTURE

OBJECTIVE: To modify the design of the Achilles tendon-scar composite flap into the Z-shape and to apply it into clinic situations to correct the tendon-scar contracture after burn and other injures. METHODS: According to degree of contracture and strephenopedia, the central limb of Z-shaped design lay in contracture line of posterior ankle area just over the Achilles tendon and extended 8 to 12 cm in length. Lateral limbs extended 5 to 8 cm and usual angles of the Z-shape was 60 degrees. The two tendon-scar composite flaps were made and slipped along the central limb between them. From March 1994 to August 1999, seven patients with Achilles tendon scar contracture were operated with this method. RESULTS: Excellent relieving of the Achilles tendon-scar contractue was achieved. No such complications happened as ischemia and necrosis of the flaps. CONCLUSION: The Z-shaped tendon-scar composite flap is practical in clinics. It is characterized by abundant blood supply, easily procedure and reliable result.
