在30侧成人下肢标本上,观测了拇展肌形态和血供。设计了以足底内侧动脉或其深支为蒂的拇展肌或肌皮瓣转位修复跟腱和皮肤缺损的术式。并作了拇展肌肌腱和跟腱的拉伸破坏试验:拇展肌肌腱载荷平均为66.4kg,跟腱载荷平均为235.2kg。两者载荷之比为1∶3.5.
In 30 adult lower extremity specimens, the morphology and blood supply of abductor hallucis were observed. A surgical approach was designed to transposition the Achilles tendon and skin defect with the transposition of the medial plantar artery or the deep branch of the abductorum hallucis or myocutaneous flap. Tensile abduction of tendon and Achilles tendon was performed on the abductor hallucis: The average tendon load of the abductor hallucis was 66.4 kg and the average load of the tendon was 235.2 kg. The ratio between the two loads is 1: 3.5.
