Three velamentous cord insertions were recorded in first trimester, none of which normalised—two remained velamentous during the pregnancy and one evolved to marginal in second trimester.

And for good reason – precision is an ally whenever you are inserting a needle into a human body. With some imagination, I am able to conjure up a gruesome Hollywood-esque image of someone gripping a syringe in a gloved fist and thrusting it towards a body with the intention of hitting a target under the skin. In my mind, there is an element of chance as to whether the needle hits the intended anatomical target. It's a stab in the dark. In a more nuanced and stable clinical scenario, the insertion point is carefully considered and the odds of missing may be relatively low. But no matter how low, it seems intuitively sensible to use any imaging guidance available. And increasingly, that guidance is provided by ultrasound. Ultrasound has been established as a helpful addition to inserting intravenous lines, taking biopsies and draining free fluid, to name but a few.</p><p>If one assumes that the person inserting a needle has absolutely no knowledge of underlying anatomy and is simply taking a stab whilst hoping it will hit its spot then it is easy to perceive the massive benefit of ultrasound-guided procedures. But that simply isn't true. Medical students spend many hours learning about surface anatomy and how it relates to the underlying layers of tissue, muscle and bone below the skin. Doctors have a great understanding of anatomy and use their hands to palpate for certain underlying structures such as bony processes, tendons and veins, in order to piece together an image in their mind about the underlying anatomy. Anyone who has had blood taken knows that those technicians who do this are adept at feeling the anatomy on the inside of the elbow to find a vein to puncture and drain blood from no matter how deep it is. It is a well-honed skill.</p><p>But taking blood is one thing, injecting substances is quite another. Intra-articular injections for the treatment of joint osteoarthritis have been popular for some time and are safely performed using anatomical landmarks only. But increasingly, practitioners are using ultrasound to guide needle placement. In this issue of AJUM, Oo <i>et al</i>.<span>¹</span> have performed a systematic review of ultrasound-guided injections and concluded that clinical outcomes are superior compared with landmark-guided injections. As a potential patient, I can see how this may build confidence in the procedure, but the added benefit of improved clinical outcomes makes ultrasound guidance even more compelling.</p><p>All new approaches come with a learning curve however and potentially some questions about who should do these procedures. Those with extensive landmark-guided experience may find the ultrasound hinders the process at first.

Ultrasound-guided IA injection has proven evidence of higher accuracy in administering IA injectates into the joints than landmark-guided or blind IA injections. However, questions remain about translating higher accuracy rates of ultrasound-guided injection into better clinical improvements. Therefore, we examined the symptomatic benefits (pain, function and patient satisfaction) of ultrasound-guided injection in knee, hip and hand OA compared with blind injections by synthesising a systematic review and meta-analysis of randomised controlled trials (RCT).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>PubMed, Medline and Embase databases were searched for eligible studies from their inception to August 28, 2023.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Out of 295 records, our meta-analysis included four RCTs (338 patients with knee OA), demonstrating significant improvement in procedural pain [−0.89 (95% CI −1.25, −0.53)], pain at follow-up [−0.51 (95% CI −0.98, −0.04)] and function [1.30 (95% CI 0.86, 1.73)], favouring ultrasound guidance.
