目的为短伸肌腱转位修复第一跖骨深横韧带提供解剖学基础。方法对48例新鲜尸体足和足趾移植再造手指手术55足短伸肌进行解剖、测量。利用短伸肌腱修复第一跖骨深横韧带。结果母短伸肌及腱全长,男性(14.10±0.77)cm,女性(12.89±0.38)cm;肌腱长度,男性(9.4O±0.51)cm,女性(8.59±0.25)cm;肌腱厚度(1.10±0.08)mm;宽度(3.90±0.12)mm,其长度足能成双股连结于第一跖骨头与第三跖骨头之间。结论短伸肌腱在长度、厚度、宽度等方面完全能够用来修复第一跖骨深横韧带。
Objective To provide an anatomical basis for the transposition of short extensor tendon to repair the first deep transverse ligament of the first metatarsal. Methods 48 cases of fresh cadaver feet and toes transplantation and reconstruction of the fingers and feet of 55 feet short extensor muscle anatomy and measurement. Repair of the first metatarsal deep transverse ligament by short extensor tendon. Results The length of the main short extensor and tendon were 14.10 ± 0.77 cm in male and 12.89 ± 0.38 cm in female. The length of tendon was 9.4 ± 0.51 cm in male and 8.59 ± 0.25 cm in female. The thickness of tendon was 1.10 ± 0.08) mm; width (3.90 ± 0.12) mm, which is sufficiently long to be double-stranded between the first metatarsal head and the third metatarsal head. Conclusions The extensors tendon can be used to repair the first transverse metatarsal deep transverse ligament in length, thickness and width.
