Inclusion Criteria:

• Adult patients undergoing elective primary total hip arthroplasty for osteoarthritis by a single surgeon.

Exclusion Criteria:

• patients age < 18,
• documented allergy to local anesthetic,
• presence of peripheral neuropathy,
• patients with current long term opioid use defined as receiving an opioid on most days in a 90 day period, and
• patients with a contraindication to spinal and regional anesthesia such as coagulopathy or infection at the site of the regional technique.
• Additionally, patients who receive general anesthesia during the surgery, either as part of the planned anesthetic (at the discretion of the patient's assigned anesthesiologist) or as a rescue anesthetic after a failed spinal, will be excluded from the study. More specifically, if a patient is found to be moving their lower extremities or showing signs of sensation in the lower extremities 15 minutes after the spinal procedure is performed, this would be considered a failed spinal. In the case of a failed spinal, general anesthesia would be required to continue with surgery. After detection of a failed spinal, the anesthesiologist would make a determination about the safety of proceeding with general anesthesia versus aborting the surgery. If safe and consented for, or if emergent general anesthesia is required, the patient would be induced (given medications to begin) general anesthesia in a manner appropriate for the individual patient, taking into account their body habitus and medical history. Any patient who undergoes general anesthesia, including those for whom it is used as a rescue anesthetic as described, will be excluded from the study.
