Tips for the IPACK Block
The IPACK block, designed as a motor-sparing technique, involves the injection of local anesthetic into the space between the popliteal artery and the posterior capsule of the knee. It offers a supplementary pain management solution to the femoral nerve or adductor canal blocks, specifically for posterior knee pain. By targeting the sensory articular branches of the sciatic nerve and avoiding the motor branches of the tibial and common peroneal nerves, the IPACK block circumvents the motor weakness and foot drop associated with traditional sciatic nerve blocks, facilitating early rehabilitation without masking potential intraoperative injuries to the common peroneal nerve.
Follow these 3 key steps for a successful IPACK block
- Place the transducer transversely over the medial aspect of the knee, 2-3 cm above the patella.
- Slide the transducer proximal and distal to identify the distal femoral shaft and popliteal artery.
- Insert the needle in-plane, from the anteromedial aspect of the knee, toward the space between the popliteal artery and femur, and inject 15-20 mL of local anesthetic.
