Study Comparing Regional Anesthetic Blocks and Periarticular Infiltration for the Management of Post-operative Pain After Direct Anterior Total Hip Arthroplasty (DA THA pain)

This study is enrolling participants by invitation only.

To compare two methods of post-operative pain management in patients undergoing total hip arthroplasty. There is a perception that the periarticular injections may not be as effective in controlling post-operative pain.

Both methods are current standard of care. The investigators want to compare the outcomes of each when patients are randomized to one of the methods compared to the other method of post-operative pain control.

Estimated Enrollment: 150
Study Start Date: May 2016
Estimated Study Completion Date: May 2019
Estimated Primary Completion Date: May 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
L2 paravertebral block
regional anesthetic nerve blocks using an L2 paravertebral block with ropivacaine
Other: L2 paravertebral block
nerve block group will receive preoperatively a L2 paravertebral block with indwelling catheter
Active Comparator: periarticular injection group
periarticular local injection into the periarticular soft tissues at the time of hip replacement using a combination of ropivacaine, epinephrine, ketorolac and morphine sulphate (periarticular injection group).
Other: periarticular injection group
periarticular injection group will receive the injection cocktail towards the end of the total hip replacement prior to skin closure.
