The aim of this project is to evaluate the efficacy of preoperative erector spinae blocks in arthroscopic hip surgery. This will be a prospective randomized controlled trial.
The aim of this project is to evaluate the efficacy of preoperative erector spinae blocks in arthroscopic hip surgery. This will be a prospective randomized controlled trial. The control group will not receive a preoperative block prior to surgery, but will receive local anesthetic at the surgical site at the conclusion of the surgery. The study group will receive a preoperative block and local anesthetic. The primary outcomes will be pain levels and opioid consumption in the post-operative care unit. The secondary outcomes will be pain levels and opioid consumption post-operatively, and functional outcome measures.

Post Anesthesia Care Unit Opioids
Total morphine milligram equivalents of administered in the post-operative care unit
Time frame: 6 hours post-operatively
Post Anesthesia Care Unit Pain
Visual analogue pain score at the time of discharge from the Post Anesthesia Care Unit in which 0 equals no pain and 10 equals extreme pain
Time frame: 6 hours post-operatively
Hip disability and Osteoarthritis Outcome Score
Hip disability and Osteoarthritis Outcome score at post-op visits in which 0 equals no pain and 100 equals unbearable pain
Time frame: 1 year post-operatively
Patient Reported Outcomes measurement Information System Score
Patient Reported Outcomes measurement Information System score at post-op visits in which 0 equals no pain and 10 equals extreme pain
Time frame: 1 year post-operatively
Range Of Motion
Hip range of motion in degrees of motion, will be examined by the operative surgeon in the office measured by flexion 0-110 degrees with 0 being no range of motion and 110 being full range of motion, internal rotation -5-25 degrees with -5 being no range of motion and -25 being full range of motion, and external rotation 0-60 degrees with 0 being no range of motion and 60 being full range of motion.
Time frame: 1 year post-operatively
Outpatient Opioids
Opioids consumed after discharge from hospital
Time frame: 4 weeks post discharge

Pain scores each day for the first 4 weeks after surgery on the Visual Analog Scale in which 0 equals no pain and 10 equals unbearable pain
Time frame: 4 weeks post discharge
