Suprainguinal Fascia Iliaca (SIFI) Block Improves Analgesia Following Total Hip Arthroplasty

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.

Arm Intervention/treatment
Experimental: Suprainguinal Fascia Iliaca (SIFI) block
A nerve block technique using a numbing medication called ropivacaine.
Procedure: Suprainguinal fascia iliaca (SIFI) block
An ultrasound guided nerve block using a medication that numbs the nerve called ropivacaine.

Drug: Ropivacaine
Local anesthetic (numbing drug)
Other Name: Naropin

Placebo Comparator: Sham group
The same nerve block technique as above, however using an inactive solution of salt water.
Procedure: Sham block
An ultrasound guided nerve block using a medication that does NOT numb the nerve called saline, or salt water.

Drug: Saline
Salt water placebo
Other Name: Salt water

Primary Outcome Measures :
  1. Numeric pain score, as measure by numerical rating scale (NRS) 11 [ Time Frame: 4 hours postoperatively ]

Secondary Outcome Measures :
  1. Cumulative opioid consumption [ Time Frame: 24 hours ]
    IV morphine equivalents

  2. Motor strength, as measured by dynamometry [ Time Frame: 4 hours postoperatively ]
  3. Numeric pain score, as measure by NRS 11 [ Time Frame: 24 hours ]
  4. Ambulation, as measured by distanced walked [ Time Frame: post-op day 0 ]
