Overview
Brief Summary
The purpose of this study is to learn if using a suprainguinal fascia iliaca (SIFI) injection technique (also called a "nerve block") that numbs the nerves going to the side and front of the upper leg will improve pain control after surgery. The SIFI technique uses a numbing solution (local anesthetics) that is injected next to nerves in the hip to reduce pain. This block may affect movement in the leg and make the legs weak. The amount of leg weakness is not known and assessment of this will be included in the study. Many institutions use the SIFI block for patients having total hip replacements, with the hope of providing good pain relief combined with improved mobility after surgery.

Outcomes
Primary Outcomes
Numeric Pain Score at 4 Hours Postoperatively, as Measured by Numerical Rating Scale (NRS) 11
Time Frame: 4 hours postoperatively
The NRS 11 ranges from 0 (no pain) to 10 (intense pain).
Secondary Outcomes
- Motor Strength, as Measured by Dynamometry(4 hours postoperatively)
- Numeric Pain Score at 24 Hours, as Measured by NRS 11(24 hours)
- Cumulative Opioid Consumption(24 hours)
- Ambulation, as Measured by Distanced Walked(post-op day 0)
