断层甲床游离移植一期修复手指甲床缺损的临床研究

目的 甲床与甲板的生长来源及组织学特征,探讨断层甲床游离移植一期修复手指甲床缺损的治疗方法的可行性、安全性,综合评价术后手指功能情况.方法 通过考证甲床与甲板的基础研究方面的进展,总结我院于2003年8月～2005年8月临床应用第一足趾断层甲床游离移植治疗外伤性甲床缺损15例20指.结果 所有患者均获得随访,随访时间7～26个月,移植甲床全部成活,甲板生长平整无明显畸形,对指端软组织保护、防止指腹软组织向背侧旋转作用明显,同时保留甲板对手指的修饰作用.结论 断层甲床游离移植符合甲床与甲体生长及生发规律,甲板外形良好,尽可能的保留了甲板基本功能,手术方法操作简单,适合在基层医院开展.

Clinical research on primary repairing of nail bed defect by fault nail bed free grafting

Objective To research the origin and histologic characteristics of nail bed and nail plate, approach the feasibility and safety of primary repairing of nail bed defect by fault nail bed free grafting, and to evaluate postoperative finger function.Methods Summarizing primary repairing of traumatic nail bed defect by fault nail bed free grafting of hallux in 15 patients 20 fingers between August 2003 and August 2005.Results Every patient got follow-up, from 7 to 26 months.All grafts survived and all nail beds grew evenly, without obvious deformity. The soft tissue of fingertips was protected and the dorsal rotation of soft tissue of finger pulps was prevented. The modification of nail beds was reserved.Conclusion Fault nail bed free grafting accord with the growth and development rule of nail bed and nail body, reserving fine exterior adapt to develop in grass-roots hospitals and basic function of nail plate, simplifying the operation, and deserved to be applied.
