Tendon Transfer for Treatment of Sequela of Nerve Injury in Lower Limbs
摘要
Introduction: Among the possible complications of compressive neuropathy and traumatic injury to the peroneal nerve is paresis for foot dorsiflexion, also known as “drop foot.” Objective: To describe the main myotendinous transfer techniques available to restore the movement of dorsiflexion in patients with drop foot. Discussion: In the myotendinous transposition technique of the tibialis posterior muscle (TPM) via circumtibial, the patient is placed in supine position, with the limb extended and a cushion under the knee. Three incisions are made in the foot: the first over the insertion point of the TPM tendon, the second above the medial malleolus, and the third on the dorsum of the foot. The tendon is sectioned at the level of the first incision, on the medial side of the foot, and pulled through the second incision, on the medial side of the ankle. After the tendon transfer in the subcutaneous plane to the third incision on the dorsum of the foot, it is sutured to the tendon of the tibialis anterior muscle with the foot in forced dorsiflexion. Conclusion: The myotendinous transfer technique of the TPM is an interesting option for the correction of the loss of dorsiflexion of the foot in cases of peroneal nerve injury.
