Brief reportOffice-Based Ultrasound-Guided Intra-Articular Hip Injection: Technique for Physiatric Practice
Section snippets
Methods
At the time of writing, we used a Merlin 1101 compact ultrasound machinea with a 6- to 12-MHz, 40-mm–long linear array transducer and standard B-mode imaging. Depending on the scanning frequency, this machine provides good visualization to a depth of 9cm below the skin. Hip injections are typically performed with the transducer frequency set at 9 or 12MHz. The 12-MHz setting provides better spatial resolution than the 9-MHz setting but with less penetration. Our procedure is to attempt
Discussion
This report shows that it is feasible for the physiatrist to perform ultrasound-guided intra-articular hip injections in an office setting with compact, portable, affordable equipment. Most important, ultrasound allows the physiatrist to identify and avoid important neurovascular structures and ensure accurate placement of the needle intra-articularly. Accurate needle placement is essential to correctly interpret a diagnostic injection or the efficacy of a therapeutic injection.
The primary
Conclusions
There are multiple indications for intra-articular hip injections in physiatric practice.1, 2, 3, 4, 5, 6, 7 Given the increasing availability, portability, and affordability of newer ultrasound machines, physiatrists can obtain the necessary skills and successfully integrate ultrasound-guided hip injections into their clinical practices. At the time of this report, formal certification programs for ultrasound-guided interventions do not exist for physiatrists. Interested physiatrists are
