The purpose of this investigation was to describe a technique for sonographically guided proximal tibiofibular joint (PTFJ) injections and compare its accuracy with that of palpation guided injections in a cadaveric model. ⋯ This cadaveric investigation suggests that sonographic guidance can be used to inject the PTFJ with a high degree of accuracy and should be considered superior to palpation guidance. Clinicians should consider using sonographic guidance to inject the PTFJ for diagnostic or therapeutic purposes when clinically indicated.

Comparative Study
Comparison of infection rates among ultrasound-guided versus traditionally placed peripheral intravenous lines.
The purpose of this study was to compare infection rates of peripheral intravenous (IV) lines placed under ultrasound guidance with traditionally placed IV lines. ⋯ Both traditional and ultrasound-guided approaches had low infection rates, suggesting that there is no increased risk of infection with ultrasound guidance for peripheral IV lines.

The purpose of this study was to determine the utility of bedside sonography to differentiate soft tissue abnormalities from joint effusions. ⋯ Our study suggests that bedside sonography is useful in differentiating joint effusions from soft tissue abnormalities and directing appropriate therapy.

Randomized Controlled Trial Comparative Study
A trainee-based randomized comparison of stimulating interscalene perineural catheters with a new technique using ultrasound guidance alone.
Compared to the well-established stimulating catheter technique, the use of ultrasound guidance alone for interscalene perineural catheter insertion is a recent development and has not yet been examined in a randomized fashion. We hypothesized that an ultrasound-guided technique would require less time and produce equivalent results compared to electrical stimulation (ES) when trainees attempt interscalene perineural catheter placement. ⋯ Trainees using a new ultrasound-guided technique can place inter-scalene perineural catheters in less time compared to a well-documented technique using ES with a stimulating catheter and can produce equivalent results.
