摘要
目的：用复合组织移植急诊修复手部掌指关节部复合组织缺损。方法：用吻合血管的跖趾关节复合组织皮瓣急诊修复手部掌指关节、肌腱、神经及皮肤缺损１６例，共１８个跖趾关节，皮瓣。面积最小４ｃｍ×７ｃｍ，最大８ｃｍ×１０ｃｍ。结果：皮瓣均成活，创面Ⅰ期愈合１２例，Ⅱ期愈合４例。术后随访６～１２个月，重建掌指关节活动度：主动屈曲平均２５度～７０度，被动屈曲３０度～８５度。主动背伸在－２０度～１０度范围。相应手指及皮瓣感觉均在Ｓ３以上。术后２个月Ｘ线片证实关节移植部位均骨性愈合，关节无狭窄。结论：该术式能在急诊时一次修复手掌指关节部多种组织缺损。
Objective: To introduce a method of repairing the composite defect of joint, tendon, nerve and skin at the metacarpophalangeal joint level. Methods:16 cases of composite tissue defect at MP joint have been treated with free transplantation of the metatarsophalangeal joint composite flap.In 2 of these cases,two metatarsophalangeal joints sharing a common vessel were harvested.The smallest flap had an area of 4cm×7cm, the largest one 8cm×10cm.Results:All flaps survived.The wound healed by first intention in 12 cases,and secondary intention in 4 cases. Each case was followed up for 6 to 12 months. The average range of motion of the reconstructed MP joint was: 25°～70°of active flexion,30°～85°of passive flexion and -20°～-10°of active extention.The sensation of the flap was above S 3 .The X ray films showed bone union without narrowing of joint space.Conclusion:The operation can be used to repair the composite tissue defects at MP joint level in one time with a promising functional result.
