Summary

The purpose of this research study is to determine if the insertion site of a perineural catheter, or tiny tube placed next to the nerves that go to the hip which you will have surgery, affects the amount of pain relief that is experienced after surgery.

Detailed description

To determine the association between perineural catheter location and postoperative analgesia, analgesic requirements, ambulatory distance, and flexion following hip arthroplasty. Primary Hypothesis: Differing the catheter insertion site (femoral vs. psoas compartment) for a perineural local anesthetic infusion is not associated with lower pain scores during the 24-hour period beginning the morning following hip arthroplasty.

Conditions

• Hip Arthroplasty
• Hip Pain

Interventions

Type	Name	Description
PROCEDURE	Femoral Nerve Block vs. Psoas Compartment Nerve Block	Patients, undergoing hip arthroplasty or hip resurfacing will be randomized to one of two groups: femoral nerve block or psoas compartment nerve block. Patients randomized to femoral nerve block will receive this block prior to surgery. Patients randomized to psoas compartment nerve block will receive this block prior to surgery. Both patients will receive Mepivicaine via catheter prior to surgery and following surgery, Ropivicaine via pain pump.
