Overview
Brief Summary
The purpose of this study is to compare infiltration pain and anesthetic efficacy between lidocaine and Bacteriostatic saline (BS) for ultrasound (US) guided intraarticular hip injections.
Detailed Description
Local anesthesia is commonly used to reduce pain during joint injections, particularly for deep joints like the hip. Lidocaine is the most commonly used local anesthetic in most medical practices. It is well known that lidocaine infiltration itself is painful. Many strategies have been studied to minimize pain associated with lidocaine administration, including buffering, warming, and slowing infiltration rate. BS is an alternative local anesthetic that has been shown to be less painful when injected into subcutaneous tissues compared with lidocaine. However, BS use has not been widely implemented for local anesthesia, and it has not been studied in the context of joint injections.

Outcomes
Primary Outcomes
VAS for Pain Score During Local Anesthesia Infiltration
Time Frame: baseline to 5-10 minutes later -- immediately after local anesthetic injection administration
The Visual Analog Scale (VAS) for Pain is a validated tool used to measure pain. A 100mm horizontal line anchored by "no pain" (score of 0) and "pain as bad as it could be" (score of 100).
Secondary Outcomes
- VAS for Pain Score During Subsequent Hip Joint Injection (Local Anesthetic Efficacy)(baseline to 5-10 minutes later -- immediately after hip joint injection)
- Anesthetic Infiltration Duration(baseline)
