Randomized Controlled Trial
[Clinical observation of ultrasound guided popliteal sciatic nerve combined saphenous nerve block for hallux valgus patients with metatarsophalangeal joint dislocation].
To explore clinical effects of ultrasound guided popliteal sciatic nerve combined saphenous nerve block in patients with anterior foot orthopedics. ⋯ Ultrasound guided popliteal sciatic nerve combined saphenous nerve block could meet demand of hallux valgus patients with metatarsophalangeal joint dislocation. Compared with lumbar anesthesia, it could maintain hemodynamic stability, prolong effective analgesia time after operation, and improve patients' overall comfort and safety for free activity above the knee joint.
