Clinical Trial Summary

The purpose of the study is to assess the accuracy of Butterfly IQ ultrasound for intra-articular hip injections, and to see if an injection given intra-articular before incision provides any benefit in preemptive pain relief or blood loss reduction.


Description:

This study is designed to be prospective randomized (1:1) controlled independent trial. Subjects are male and female, aged 18 and above, who are suitable candidates for either a unilateral (i.e. single) total hip replacement. Subjects that are scheduled with a single, extensively trained Physician Assistant assisting in their surgery will be exclusively included. This is single site study with projected enrollment of 150 subjects

Outcome

Type Measure Description Time frame Safety issue
Primary Accuracy Primary objective is to determine the accuracy of the Butterfly IQ portable app based ultrasound device used in intra-articular hip injections determined by patient reported pain ratings using the PROMIS pain score Surgery
Secondary Blood Loss Evaluate blood loss as determined by relative change in HCT preoperatively and on the first post-operative day. Postoperative day 1
