There is a growing interest in the application of ultrasound (US) guidance for diagnostic and therapeutic joint injections. US provides direct visualization of soft tissues and the outer borders of bony structures. With real-time needle guidance the success rate of intra-articular injections improves and iatrogenic damage to anatomic structures can be avoided. An US machine is more readily available, transferrable and more affordable than a fluoroscopy machine or CT scanner and lacks the risk of radiation. These factors make US a valuable alternative to procedures performed either blind or under fluoroscopic or CT guidance. This article focuses on the rationale for injections in the upper and lower extremity joints and describes and illustrates the different US-guided injection techniques.

The evolution of regional anesthesia techniques has markedly influenced the management of postoperative pain, particularly in thoracic surgery. As part of a multimodal analgesic approach, fascial plane blocks have gained prominence due to their efficacy in providing targeted analgesia with minimal systemic side effects. Among these, the superficial intercostal plane (SPIP) block and deep parasternal intercostal plane (DPIP) block are of notable interest.

Gas bubbles, commonly used in medical ultrasound (US), witness advancements with nanobubbles (NB), providing improved capabilities over microbubbles (MB). NBs offer enhanced penetration into capillaries and the ability to extravasate into tumors following systemic injection, alongside prolonged circulation and persistent acoustic contrast. Low-frequency insonation (<1 MHz) with NBs holds great potential in inducing significant bioeffects, making the monitoring of their acoustic response critical to achieving therapeutic goals.

Rationale And Objectives: This study aimed to evaluate the efficacy of ultrasound (US)-guided local steroid injection in carpal tunnel syndrome (CTS) using shear wave elastography (SWE).
Materials And Methods: A total of 47 wrists from 41 patients diagnosed with mild to moderate idiopathic CTS, based on clinical and electrophysiological criteria, were enrolled between June and October 2024. All participants underwent US-guided local steroid injection.

Background: Laparoscopic radical gastrectomy has been reported to be associated with substantial trauma and pain. This study compared the impact of ultrasound-(US)-guided, bilateral, double-injection intertransverse process block (ITPB) on postoperative analgesia with subcostal transversus abdominis plane block (TAPB) in patients who were undergoing laparoscopic radical gastrectomy.
Methods: Sixty-two patients who were undergoing laparoscopic radical gastrectomy surgery under general anesthesia were included.

Article Synopsis
- Cervical radiculopathies are typically treated with nerve root injections, and this study introduces a new ultrasound-guided technique for better visualization and injection accuracy.
- A 56-year-old patient with chronic C6 radiculopathy received treatment using this method, combining 5% dextrose and vitamin B12, which significantly improved their symptoms.
- The new technique ensures precise needle placement and effective medication spread while minimizing risks and reducing the need for fluoroscopy, lowering radiation exposure and enhancing treatment outcomes.
