Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Subgluteal Sciatic Nerve Block

Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the subgluteal location 1-3 cm caudad to the inferior border of the gluteus maximus muscle.

Group Type ACTIVE_COMPARATOR

Subgluteal Sciatic Nerve Block

Intervention Type PROCEDURE

Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the subgluteal location 1-3 cm caudad to the inferior border of the gluteus maximus muscle. After catheter placement, outcome measures will be assessed.

Popliteal Sciatic Nerve Block

Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the popliteal location 1-3 cm cephalad to the sciatic bifurcation.

Group Type ACTIVE_COMPARATOR

Popliteal Sciatic Nerve Block

Intervention Type PROCEDURE

Patients randomized to this group will receive a sciatic nerve block with the catheter tip insertion at the popliteal location 1-3 cm cephalad to the sciatic bifurcation. After Catheter placement outcome measures will be assessed.
