槌趾に対する長母指屈筋腱延長術について

抄録

A school boy aged seventeen years sustained a open fracture of right tibial and fibular shaft in a motorcycle accident.
He had marked swelling of the injured leg and loss of sensation in right foot.
When the plaster was removed a month later, he noticed equino-varus deformity of right ankle and clawed deformity of right toes.
We repaired the clawed deformities of the hallux and other toes by the lengthening of the flexor hallucis longus tendon.
The slip between the flexor hallucis longus and flexor digitorum longus tendon was confirmed anatomically.
We think the lengthening of the flexor hallucis longus tendon is a excellent treatment for the claw toe deformity which was not caused by paralysis of the intrinsic muscles.
