Extensor (foot mother) long tendon transfer

1. Can be used as an orthopaedic toe claw toe. The claw toe is flexion of the interphalangeal joint, the metatarsophalangeal joint is overextended, and the metatarsal head is plantar flexion at the same time. Patients with claw-shaped toes can have diarrhea due to pressure on the toe end, back of the toe, and bottom of the forefoot, which affects walking and standing. The deformity can be corrected by using the long tendon extension and interphalangeal joint fusion. 2. Can be used as an auxiliary operation to correct high arched feet. High arched feet, also known as hollow feet and claw-shaped feet, have three characteristics: ⑴ forefoot plantar flexion combined with high arch; ⑵ may have an enlarged heel; ⑶ toe upturned or Claw shape [Figure 1]. High arched feet are mostly caused by weakened dorsi extensor muscles and paralysis of interosseous and vermiform muscles. This deformity is more common in children over 3 years of age, and it increases with age. Although the deformity of the foot is not serious, it can seriously affect the function of the diseased foot. Therefore, for those who still have malformations in non-surgical treatment, early surgery should be used to balance muscle strength to prevent the development of malformations. The extension of the extensor long tendon can be used as an auxiliary orthopedic operation. In addition to correcting the toe or claw shape, it can also improve the extension of the back of the foot, correct the forefoot flexion and the high arch. 3. It can be used as an auxiliary operation to enhance the dorsiflexion of the foot and adjust the balance of muscle strength, such as varus varus foot caused by peroneus paralysis. It can transfer the tibialis anterior tendon to the sacrum and transfer the long tendon of the extensor to the first. 1 Metatarsal neck; For the plantar flexion and valgus foot caused by the tibialis anterior muscle paralysis, the long fibular tendon can be transferred to the back of the foot, and the long tendon of the extensor foot can also be transferred. In this way, on one hand, the back extension force of the foot can be enhanced, and on the other hand, the balance of the inward and outward force of the foot can be maintained to prevent secondary deformities.
