摘　　要：游离第２足趾或关节移植术是最主要的拇、手指再造方法之一。但至今尚未见有关供足Ｘ线方面研究的报告。笔者采用双足标准正位及负重侧位Ｘ线摄片，对２７例术后病人平均随访５．６６年。按手术截趾平面及随访时间不同行自身对照分层分析。结果；（１）第１跖骨和其近节趾骨长轴夹角比非手术侧平均增大３．７５°，原有外翻畸形的病人，术后供足畸形加重；（２）跖骨截骨组的远期随访病人供足外侧纵弓平均增大３°，（３）术后供足１～３趾间距平均比非手术侧小９．１３ｍｍ；（４）术后供足最大宽度变小；（５）跖骨截骨组４１．６７％的病人出现残留跖骨密度降低。本组只有少数病人稍感供足不适，但均不需治疗。Free seconad toe and joint transfer is one of the most important methods in thumb or finger reconstruction. But so far, report on the donor foot X-ray changes with both feet under weight has not been seen. We studied 27 cases. The average follow-up period was 5. 66 years (3 month to 17 years ). The results were evaluated statistically by self-controlled and sectional analyses according to the plane of resection and follow-up time. The concluSions were: (1)The first metatnrsophalangeal angle averagely increased 3. 75 degree, comparing with non-operative foot. The donor foot deformity would be more obvious in patients with hallux valnus after operation. (2)Lateral longitudinal arch averagely increased 3 degrees in long term metatarsal refection cases. (3)The distance between big and third toe in the donor foot averagely shortened 9. 13 millimeters. (4)The biggest width of the donor foot reduced after operation. (5)In 41. 67 percent of patients the density of survived metatarsal decreased. Slight trouble existed in only a few patients in this group, and was not noticed generally.
