Case study: Calcaneal fracture
A 45-year-old male patient arrived at the emergency room in severe pain, exhibiting a deformed right heel following a fall from a ladder. X-ray imaging confirmed the presence of a calcaneal fracture. Due to the complex nature of the fracture, surgical intervention was recommended.
Nerve block techniques
The calcaneus fracture repair was performed under a popliteal and adductor canal block.
- Popliteal block: A high-frequency linear transducer was used to identify the sciatic nerve sheath in the popliteal fossa. A 22-gauge needle was advanced out-of-plane under ultrasound guidance to administer 15 mL of 1% ropivacaine into the sciatic nerve sheath between the tibial and common peroneal nerves.

- Adductor canal block: After identifying the saphenous nerve in the adductor canal, 5 mL of 1% ropivacaine was injected for tourniquet pain management. The tourniquet was positioned just below the knee for the surgical procedure.

SaN, saphenous nerve; FA, femoral artery; FV, femoral vein; SaM, sartorius muscle; VMM, vastus medialis muscle; ALM, adductor longus muscle; AMM, adductor magnus muscle.
The combination of the popliteal and adductor canal blocks served as a complete anesthetic and postoperative analgesia in this patient. The patient reported minimal pain in the immediate postoperative period with a pain score of 1-2/10. The surgery itself proceeded smoothly, without any complications. Early postoperative mobilization was encouraged and showed good progress.
